Accounting Policies [Abstract] | |
Significant Accounting Policies [Text Block] | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation Except as otherwise indicated by the context, the terms "Corporation" and "UCC" as used herein mean Union Carbide Corporation and its consolidated subsidiaries. The accompanying consolidated financial statements of the Corporation were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Corporation exercises control and, when applicable, entities for which the Corporation has a controlling financial interest. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method. The Corporation is a wholly owned subsidiary of The Dow Chemical Company ("Dow"). In accordance with the accounting requirements for wholly owned subsidiaries, the presentation of earnings per share is not required and therefore is not provided. The Corporation’s business activities comprise components of Dow’s global operations rather than stand-alone operations. Dow conducts its worldwide operations through principal product groups. Because there are no separable reportable business segments for UCC under the accounting guidance related to segment reporting and no detailed business information is provided to a chief operating decision maker regarding the Corporation’s stand-alone operations, the Corporation’s results are reported as a single operating segment. Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017, Dow and E. I. du Pont de Nemours and Company ("DuPont") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Dow and DuPont became subsidiaries of DowDuPont (the "Merger"). See Note 3 for additional information. Use of Estimates in Financial Statement Preparation The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Corporation's consolidated financial statements include amounts that are based on management's best estimates and judgments. Actual results could differ from those estimates. Related Companies Transactions with the Corporation's parent company, Dow, and other subsidiaries of Dow and DowDuPont have been reflected as related company transactions in the consolidated financial statements. Significant Accounting Policies Asbestos-Related Matters Accruals for asbestos-related matters, including defense and processing costs, are recorded based on an analysis of claim and resolution activity, defense spending and pending and future claims. These accruals are assessed at each balance sheet date to determine if the asbestos-related liability remains appropriate. Accruals for asbestos-related matters are included in the consolidated balance sheets in "Asbestos-related liabilities - current" and "Asbestos-related liabilities - noncurrent." This accounting policy was added in the fourth quarter of 2016. See Note 14 for additional information. Legal Costs The Corporation expenses legal costs as incurred, with the exception of defense and processing costs associated with asbestos-related matters. Foreign Currency Translation While the Corporation's consolidated subsidiaries are primarily based in the United States, the Corporation has small subsidiaries in Asia Pacific and the rest of the world. For those subsidiaries, the local currency has been primarily used as the functional currency. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in "Accumulated other comprehensive loss" ("AOCL"). Where the U.S. dollar is used as the functional currency, foreign currency gains and losses are reflected in income. Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in "Accrued and other current liabilities" and "Other noncurrent obligations" at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets in "Accounts receivable - Other." Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable. Cash and Cash Equivalents Cash and cash equivalents include time deposits and investments with maturities of three months or less at the time of purchase. Financial Instruments The Corporation calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Corporation uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows. Inventories Inventories are stated at the lower of cost or net realizable value. The method of determining cost for each subsidiary varies among last-in, first-out ("LIFO"); first-in, first-out ("FIFO"); and average cost, and is used consistently from year to year. The Corporation routinely exchanges and swaps raw materials and finished goods with other companies to reduce delivery time, freight and other transportation costs. These transactions are treated as non-monetary exchanges and are valued at cost. Property Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income. Impairment and Disposal of Long-Lived Assets The Corporation evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset's carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value, and depreciation is recognized over the remaining useful life of the assets. Other Intangible Assets Finite-lived intangible assets such as purchased customer lists, developed technology, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years. Investments in Related Companies Investments in related companies consist of the Corporation's ownership interests in Dow subsidiaries located in North America and Latin America. The Corporation accounts for these investments using the cost method as it does not have significant influence over the operating and financial policies of these related companies. Revenue Substantially all of the Corporation's revenues are generated by sales to Dow. Approximately 99 percent of the Corporation's sales are related to sales of product ( 99 percent in 2016 and 99 percent in 2015 ); the remaining 1 percent is related to the licensing of patents and technology ( 1 percent in 2016 and 1 percent in 2015 ). Revenue for product sales to related companies is recognized as risk and title to the product transfer to the related company, which occurs either at the time production is complete or free on board ("FOB") UCC's manufacturing facility, in accordance with the sales agreement between the Corporation and Dow. Revenue for product sales to trade customers is recognized as risk and title to the product transfer to the customer, which for trade sales, usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. UCC's standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as "Cost of sales" in the consolidated statements of income. Revenue related to the initial licensing of patents and technology is recognized when earned; revenue related to running royalties is recognized according to licensee production levels. Severance Costs Management routinely reviews its operations around the world in an effort to ensure competitiveness across its operations and geographic regions. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under ongoing benefit arrangements. These severance costs are accrued once management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated. Integration and Separation Costs The Corporation classifies expenses related to the Merger as integration and separation costs. Merger-related costs include: costs incurred to prepare for and close the Merger, post-Merger integration expenses and costs incurred to prepare for the separation of Dow’s agriculture business, specialty products business and materials science business. This accounting policy was added in the third quarter of 2017 as a result of the Merger. Income Taxes The Corporation accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The Corporation is included in the same consolidated federal income tax group and consolidated income tax return as Dow. The Corporation accounts for its income taxes following the formula in the Dow-UCC Tax Sharing Agreement used to compute the amount due to Dow or UCC for UCC's share of taxable income and tax attributes on the consolidated income tax return. This method generally follows the separate return method. The amounts reported as income taxes payable or receivable represent the Corporation's payment obligation (or refundable amount) to Dow based on a theoretical tax liability calculated on a separate return method. The Corporation recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Corporation accrues for non-income tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested. Changes in Financial Statement Presentation Consolidated Statements of Income In the third quarter of 2017, the Corporation changed the presentation of certain line items on the face of the consolidated statements of income to conform to the presentation that was adopted for DowDuPont. Costs associated with integration and separation activities are now separately reported as "Integration and separation costs" and "Interest income" has been reclassified to "Sundry income (expense) - net." The following table summarizes the changes made to the consolidated statements of income for the years ended December 31, 2016 and 2015: Summary of Changes to the Consolidated Statements of Income 2016 2015 In millions As Filed Updated As Filed Updated Sundry income (expense) - net $ 2 $ 16 $ (30 ) $ (22 ) Interest income $ 14 $ — $ 8 $ — Consolidated Statements of Cash Flows In the first quarter of 2017, the Corporation made a change to the consolidated statements of cash flows to include a new line under "Operating Activities" entitled "Asbestos-related payments." The new line captures cash payments made for asbestos-related claim and resolution activity as well as asbestos-related defense and processing costs (effective as of the fourth quarter of 2016 as a result of an accounting policy change). In the third quarter of 2017, the Corporation changed the presentation to the consolidated statements of cash flows to conform to the presentation that was adopted for DowDuPont. "Net periodic pension benefit cost" is now separately reported and has been reclassified from "Other assets and liabilities."

RECENT ACCOUNTING GUIDANCE
RECENT ACCOUNTING GUIDANCE | 12 Months Ended |

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
Recent Accounting Guidance [Text Block] | RECENT ACCOUNTING GUIDANCE Accounting Guidance Issued But Not Adopted at December 31, 2017 In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities. Entities will have the option of using either a full retrospective approach or a modified approach to adopt the guidance in ASU 2014-09. In May 2014, the FASB and International Accounting Standards Board formed The Joint Transition Resource Group for Revenue Recognition ("TRG"), consisting of financial statement preparers, auditors and users, to seek feedback on potential issues related to the implementation of the new revenue standard. As a result of feedback from the TRG, the FASB issued additional guidance to provide clarification, implementation guidance and practical expedients to address some of the challenges of implementation. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which is an amendment on assessing whether an entity is a principal or an agent in a revenue transaction. This amendment addresses issues to clarify the principal versus agent assessment and leads to more consistent application. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," which contains amendments to the new revenue recognition standard on identifying performance obligations and accounting for licenses of intellectual property. The amendments related to identifying performance obligations clarify when a promised good or service is separately identifiable and allows entities to disregard items that are immaterial in the context of a contract. The licensing implementation amendments clarify how an entity should evaluate the nature of its promise in granting a license of intellectual property, which will determine whether revenue is recognized over time or at a point in time. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," which provides clarity and implementation guidance on assessing collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The new standards have the same effective date and transition requirements as ASU 2014-09. The Corporation analyzed the impact of ASU 2014-09 and the related ASU's across all revenue streams to evaluate the impact of the new standard on revenue contracts. This included reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. The Corporation has completed contract reviews and validated the results of applying the new revenue guidance. The Corporation has finalized its accounting policies, the evaluation of the impact of the accounting and disclosure requirements on its business processes, controls and systems, and is currently drafting new disclosures required post-implementation in 2018. The Corporation will adopt the new standard using the modified retrospective approach, under which the cumulative effect of initially applying the new guidance is recognized as an adjustment to the opening balance of retained earnings in the first quarter of 2018. Based on the completed analysis, the Corporation has determined the adjustment will not have a material impact on the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases with lease terms of more than twelve months and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance will require disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from current U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance issued in 2014. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, using a modified retrospective approach, and early adoption is permitted. The Corporation has a team in place to evaluate the new guidance and is in the process of implementing a software solution to facilitate the development of business processes and controls around leases to the meet the new accounting and disclosure requirements upon adoption in the first quarter of 2019. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning period of adoption. Early adoption is permitted in the first interim period of an annual reporting period for which financial statements have not been issued. The Corporation will adopt the new guidance in the first quarter of 2018 and the adoption of this guidance will not have a material impact on the consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets," which clarifies the scope of guidance on nonfinancial asset derecognition in Accounting Standards Codification 610-20 and the accounting for partial sales of nonfinancial assets. The new guidance also conforms the derecognition guidance for nonfinancial assets with the model in the new revenue standard (ASU 2014-09). The new standard is effective for annual reporting periods, and interim periods within those fiscal years, beginning after December 15, 2017, and an entity is required to apply the amendments at the same time that it applies the amendments in ASU 2014-09. The Corporation will apply the new guidance with the implementation of the new revenue standard in the first quarter of 2018 and the adoption of the guidance will not have a material impact on the consolidated financial statements. In March 2017, the FASB issues ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which amends the requirements related to the income statement presentation of the components of net periodic benefit cost for employer sponsored defined benefit pension and other postretirement benefit plans. Under the new guidance, an entity must disaggregate and present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period, and only the service cost component will be eligible for capitalization. Other components of net periodic benefit cost will be presented separately from the line item(s) that includes the service cost. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted at the beginning of an annual period in which the financial statements have not been issued. Entities must use a retrospective transition method to adopt the requirement for separate presentation of the income statement service cost and other components, and a prospective transition method to adopt the requirement to limit the capitalization of benefit cost to the service component. The Corporation will adopt the new guidance in the first quarter of 2018 using a retrospective transition method to reclassify net periodic benefit cost, other than the service cost component, from "Cost of sales," "Research and development expenses" and "Selling, general and administrative expenses" to "Sundry income (expense) - net" in the consolidated statements of income. |

MERGER WITH DUPONT [Abstract] | |
Merger with DuPont [Text Block] | Effective August 31, 2017, Dow and DuPont completed the previously announced merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), by and among Dow, DuPont, DowDuPont, Diamond Merger Sub, Inc. and Orion Merger Sub, Inc. Pursuant to the Merger Agreement, (i) Diamond Merger Sub, Inc. was merged with and into Dow, with Dow surviving the merger as a subsidiary of DowDuPont (the "Diamond Merger") and (ii) Orion Merger Sub, Inc. was merged with and into DuPont, with DuPont surviving the merger as a subsidiary of DowDuPont (the "Orion Merger" and, together with the Diamond Merger, the "Mergers"). Following the consummation of the Mergers, each of Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Following the Merger, Dow and DuPont intend to pursue, subject to approval by the board of directors of DowDuPont ("DowDuPont Board"), the separation of the combined company's agriculture business, specialty products business and materials science business through one or more tax-efficient transactions ("Intended Business Separations"). On August 31, 2017, following the Diamond Merger, Dow requested that the New York Stock Exchange ("NYSE") withdraw the shares of Dow Common Stock from listing on the NYSE and file a Form 25 with the U.S. Securities and Exchange Commission ("SEC") to report that the shares of Dow Common Stock are no longer listed on the NYSE. The shares of Dow Common Stock were suspended from trading on the NYSE prior to the open of trading on September 1, 2017. On September 12, 2017, DowDuPont announced that the DowDuPont Board and management, with the assistance of independent advisors, completed their comprehensive review of the portfolio composition of the three intended independent companies. The DowDuPont Board unanimously concluded that, in light of knowledge gained since the announcement of the proposed merger of equals, certain targeted adjustments will be made between the materials science and specialty products businesses, which will enhance the competitive advantages of the intended resulting companies. As a result of this change, it is expected that a portion of UCC's business will move to the specialty products business as part of the Intended Business Separations, and the Corporation does not expect the Intended Business Separations to have a material impact on the Consolidated Financial Statements. |

Divestitures [text block] | DIVESTITURE Divestiture of Methylmercapto Propionaldehyde Assets On November 1, 2015, the Corporation completed the sale of its assets related to the production of methylmercapto propionaldehyde ("MMP") at the St. Charles Operations site in Taft, Louisiana to MMP SCO, LLC ("Novus"), a subsidiary of Novus International, Inc., for net proceeds of $31 million . Included in the divestiture was the Corporation's MMP manufacturing facility, as well as inventory. The Corporation continues to operate and provide services to the MMP facility under separate agreements with Novus. The net proceeds were included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets as a deferred gain and will be amortized to "Sundry income (expense) - net" in the consolidated statements of income over the 25-year term of the operating agreements. The transaction also included a 25-year acrolein supply agreement containing an upfront payment of $42.5 million which was reflected in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets and will be amortized to "Net trade sales" over the 25-year term of the agreement. Proceeds of $10 million for the sale of two related patents resulted in a pretax gain of $10 million and was included in "Sundry income (expense) - net" in the consolidated statements of income. |

Restructuring and Related Activities [Abstract] | |
Restructuring and Related Activities Disclosure [Text Block] | RESTRUCTURING AND ASSET RELATED CHARGES - NET 2017 Restructuring and Asset Related Charges In September 2017, the Corporation approved restructuring actions that are aligned with DowDuPont's synergy targets. As a result of these actions, the Corporation recorded a pretax restructuring charge for severance and related benefit costs of $8 million in the third quarter of 2017. In November 2017, the Corporation approved additional restructuring actions in connection with the restructuring program. A pretax restructuring charge for severance and related benefit costs of $2 million was recorded in the fourth quarter of 2017, as well as charges of $62 million for the write-off and write-down of manufacturing and facility assets at multiple UCC sites, including a steam unit in Institute, West Virginia. The impact of these charges was shown as "Restructuring and asset related charges - net" in the consolidated statements of income. These actions are expected to be substantially completed by the end of 2019. At December 31, 2017, severance of $2 million had been paid, leaving a liability of $8 million . 2016 Restructuring On June 27, 2016, the Corporation approved actions to further improve cost effectiveness with additional workforce reductions. As a result of these actions, the Corporation recorded a pretax restructuring charge in the second quarter of 2016 consisting of severance and related benefit costs of $1 million for the separation of approximately 5 positions. In the fourth quarter of 2016, the Corporation recorded an additional charge of $2 million related to the separation of an additional 16 positions, and in the second quarter of 2017, an additional charge of $2 million was recorded to adjust the charge for severance and related benefit costs. The impact of these charges was shown as "Restructuring and asset related charges - net" in the consolidated statements of income. At December 31, 2017, the liability for severance and related benefit costs was zero , substantially completing the 2016 restructuring program. 2015 Restructuring and Asset Related Charges On April 29, 2015, the Corporation approved actions to improve the cost effectiveness of the Corporation's global operations and further streamline the organization. These actions affected approximately 16 positions and resulted in the shutdown of a manufacturing facility that produced water soluble polymers in Institute, West Virginia, in the fourth quarter of 2015. As a result of these actions, the Corporation recorded pretax restructuring charges of $18 million in the second quarter of 2015 consisting of costs associated with exit and disposal activities of $2 million , severance and related benefit costs of $2 million and asset related charges of $14 million . In the fourth quarter of 2015, the Corporation recorded an additional charge of $1 million related to the separation of an additional 8 positions. At December 31, 2015, severance of $1 million had been paid, leaving a liability of $2 million for approximately 15 employees. During the second quarter of 2016, the Corporation recorded an unfavorable adjustment to the 2015 restructuring charge related to additional accruals for exit and disposal activities of $1 million , included in "Restructuring and asset related charges - net" in the consolidated statements of income. In 2016, severance of $2 million was paid, substantially completing the 2015 restructuring activities, with any remaining liabilities for contract cancellation fees to be settled over time. The Corporation expects to incur additional costs in the future related to restructuring activities, as UCC continually looks for ways to enhance the efficiency and cost effectiveness of its operations. Future costs are expected to include demolition costs related to the closed facilities; these will be recognized as incurred. The Corporation also expects to incur additional employee related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time. |

Income Tax Expense (Benefit), Continuing Operations [Abstract] | |
Income Tax Disclosure [Text Block] | INCOME TAXES On December 22, 2017, the Tax Cuts and Jobs Act ("The Act") was enacted. The Act reduces the U.S. federal corporate income tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves to a territorial system. At December 31, 2017, the Corporation had not completed its accounting for the tax effects of The Act; however, as described below, the Corporation made a reasonable estimate of the effects on its existing deferred tax balances and the one-time transition tax. In accordance with Staff Accounting Bulletin 118 (“SAB118”), income tax effects of The Act may be refined upon obtaining, preparing or analyzing additional information during the measurement period and such changes could be material. During the measurement period, provisional amounts may also be adjusted for the effects, if any, of interpretive guidance issued after December 31, 2017, by U.S. regulatory and standard-setting bodies. • As a result of The Act, the Corporation remeasured its U.S. federal deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent. However, the Corporation is still analyzing certain aspects of The Act and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the remeasurement of the Corporation’s deferred tax balance was $250 million , recorded as a charge to "Provision (Credit) for income taxes." • The Act requires a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits ("E&P"), which results in a one-time transition tax. As a result, the Corporation recorded an insignificant provisional amount for the transition tax liability for its foreign subsidiaries. The Corporation has not yet completed its calculation of the total post-1986 foreign E&P for its foreign subsidiaries as E&P will not be finalized until the DowDuPont federal income tax return is filed. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets, which is a defined term under The Act. • For tax years beginning after December 31, 2017, The Act introduces new provisions for U.S. taxation of certain global intangible low-taxed income ("GILTI"). Due to its complexity and a current lack of guidance as to how to calculate the tax, the Corporation is not yet able to determine a reasonable estimate for the impact of the incremental tax liability. When additional guidance is available, the Corporation will make a policy election on whether the additional liability will be recorded in the period in which it is incurred or recognized for the basis differences that would be expected to reverse in future years.

The tax rate for 2017 was unfavorably impacted by The Act and the recognition of a deferred gain. The tax rate for 2016 was favorably impacted by the release of a reserve in excess of the settlement of an uncertain tax position and from the asbestos-related charge. The tax rate for 2015 was favorably impacted by changes in valuation allowances on state income tax attributes. A change in uncertain tax positions in the fourth quarter of 2015 unfavorably impacted the tax rate and resulted in an increase in "Deferred income tax assets" and "Other noncurrent obligations" in the consolidated balance sheets. A transaction for the sale of stock between the Corporation and Dow in 2014 created a gain that was initially deferred for tax purposes. This deferred gain became taxable as a result of activities executed in anticipation of the intended separation of DowDuPont into three publicly traded companies. As a result, in the third quarter of 2017, the Corporation increased “Income taxes payable” in the consolidated balance sheets and recorded a charge to "Provision (Credit) for income taxes" in the consolidated statements of income of $97 million .

As a result of the settlement, the Corporation recorded a net decrease to uncertain tax positions of $67 million in "Other noncurrent obligations" in the consolidated balance sheets. The Corporation is included in Dow's consolidated federal income tax group and consolidated tax return. Current and deferred tax expenses are calculated for the Corporation as a stand-alone group and are allocated to the group from the consolidated totals, consistent with the Dow-UCC Tax Sharing Agreement. UCC is currently under examination in a number of tax jurisdictions, including the U.S. federal and various state jurisdictions. It is reasonably possible that these examinations may be resolved within twelve months. The impact on the Corporation’s results of operations is not expected to be material. Tax years that remain subject to examination for the Corporation's major tax jurisdictions are shown below: Tax Years Subject to Examination by Major Tax Jurisdiction at Dec 31, 2017 Earliest Open Year Jurisdiction United States: Federal income tax 2004 State and local income tax 2004 Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law, both legislated and concluded through the various jurisdictions' tax court systems. It is the opinion of the Corporation's management that the possibility is remote that costs in excess of those accrued will have a material impact on the Corporation's consolidated financial statements. |

Such covenants are typically based on the Corporation's size and financial position and include, subject to the exceptions and qualifications contained in the indentures, obligations not to (i) allow liens on principal U.S. manufacturing facilities, (ii) enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, or (iii) merge into or consolidate with any other entity or sell or convey all or substantially all of its assets. Failure of the Corporation to comply with any of these covenants could, after the passage of any applicable grace period, result in a default under the applicable indenture which would allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the subject notes. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies Disclosure [Text Block] | COMMITMENTS AND CONTINGENT LIABILITIES Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. At December 31, 2017 , the Corporation had accrued obligations of $114 million for probable environmental remediation and restoration costs, including $19 million for the remediation of Superfund sites. These obligations were included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets. This is management's best estimate of the costs for remediation and restoration with respect to environmental matters for which the Corporation has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately three times that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the Corporation's results of operations, financial condition and cash flows. It is the opinion of the Corporation's management that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Corporation's results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. At December 31, 2016 , the Corporation had accrued obligations of $145 million for probable environmental remediation and restoration costs, including $20 million for the remediation of Superfund sites. In the fourth quarter of 2016, the Corporation recorded an adjustment to the environmental accrual, primarily resulting from the culmination of negotiations with regulators and/or final stages of certain remediation projects. These charges were included in "Cost of sales" in the consolidated statements of income and were included in the total obligation of $145 million .

Capital expenditures for environmental protection were $9 million in 2017 , $10 million in 2016 and $14 million in 2015 . Litigation The Corporation is involved in a number of legal proceedings and claims with both private and governmental parties. These cover a wide range of matters, including, but not limited to: product liability; trade regulation; governmental regulatory proceedings; health, safety and environmental matters; employment; patents; contracts; taxes; and commercial disputes. Asbestos-Related Matters Introduction Separately, the Corporation is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that UCC sold in the past, alleged exposure to asbestos-containing products located on UCC's premises, and UCC's responsibility for asbestos suits filed against a former UCC subsidiary, Amchem Products, Inc. ("Amchem"). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to the Corporation's products. The Corporation expects more asbestos-related suits to be filed against UCC and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims. Estimating the Liability for Asbestos-Related Pending and Future Claims Based on a study completed by Ankura Consulting Group, LLC ("Ankura") in January 2003, the Corporation increased its December 31, 2002, asbestos-related liability for pending and future claims for a 15-year period ending in 2017 to $2.2 billion , excluding future defense and processing costs. Since then, the Corporation has compared current asbestos claim and resolution activity to the results of the most recent Ankura study at each balance sheet date to determine whether the accrual continues to be appropriate. In addition, the Corporation has requested Ankura to review the Corporation's historical asbestos claim and resolution activity each year since 2004 to determine the appropriateness of updating the most recent Ankura study. In October 2016, the Corporation requested Ankura to review its historical asbestos claim and resolution activity and determine the appropriateness of updating its December 2014 study. In response to the request, Ankura reviewed and analyzed asbestos-related claim and resolution data through September 30, 2016. The resulting study, completed by Ankura in December 2016, provided estimates for the undiscounted cost of disposing of pending and future claims against UCC and Amchem, excluding future defense and processing costs, for both a 15-year period and through the terminal year of 2049. Based on the study completed in December 2016 by Ankura, and the Corporation's own review of the asbestos claim and resolution activity, it was determined that an adjustment to the accrual was necessary. The Corporation determined that using the estimate through the terminal year of 2049 was more appropriate due to increasing knowledge and data about the costs to resolve claims and diminished volatility in filing rates. Using the range in the Ankura December 2016 study, which was estimated to be between $502 million and $565 million for the undiscounted cost of disposing of pending and future claims, the Corporation increased its asbestos-related liability for pending and future claims through the terminal year of 2049 by $104 million , included in "Asbestos-related charge" in the consolidated statements of income. At December 31, 2016 , the Corporation's asbestos-related liability for pending and future claims was $486 million , and approximately 14 percent of the recorded liability related to pending claims and approximately 86 percent related to future claims. Estimating the Liability for Asbestos-Related Defense and Processing Costs In September 2014, the Corporation began to implement a strategy designed to reduce and to ultimately stabilize and forecast defense costs associated with asbestos-related matters. The strategy included a number of important changes including: invoicing protocols including capturing costs by plaintiff; review of existing counsel roles, work processes and workflow; and utilization of enterprise legal management software, which enabled claim-specific tracking of asbestos-related defense and processing costs. The Corporation reviewed the information generated from this new strategy and determined that it now had the ability to reasonably estimate asbestos-related defense and processing costs for the same periods that it estimates its asbestos-related liability for pending and future claims. The Corporation believes that including estimates of the liability for asbestos-related defense and processing costs provides a more complete assessment and measure of the liability associated with resolving asbestos-related matters, which the Corporation believes is preferable in these circumstances. In October 2016, in addition to the study for asbestos claim and resolution activity, the Corporation requested Ankura to review asbestos-related defense and processing costs and provide an estimate of a reasonable forecast of defense and processing costs associated with resolving pending and future asbestos-related claims facing UCC and Amchem for the same periods of time that the Corporation uses for estimating resolution costs. In December 2016, Ankura conducted the study and provided the Corporation with an estimate of future defense and processing costs for both a 15-year period and through the terminal year of 2049. The resulting study estimated asbestos-related defense and processing costs for pending and future asbestos claims to be between $1,009 million and $1,081 million through the terminal year of 2049. In the fourth quarter of 2016, the Corporation elected to change its method of accounting for asbestos-related defense and processing costs from expensing as incurred to estimating and accruing a liability. This change is believed to be preferable as asbestos-related defense and processing costs represent expenditures related to legacy activities that do not contribute to current or future revenue generating activities of the Corporation. The change is also reflective of the manner in which the Corporation manages its asbestos-related exposure, including careful monitoring of the correlation between defense spending and resolution costs. Together, these two sources of cost more accurately represent the "total cost" of resolving asbestos-related claims now and in the future. This accounting policy change was reflected as a change in accounting estimate effected by a change in accounting principle. As a result of this accounting policy change and based on the December 2016 Ankura study of asbestos-related defense and processing costs and the Corporation's own review of the data, a pretax charge for asbestos-related defense and processing costs of $1,009 million was recorded in the fourth quarter of 2016, included in "Asbestos-related charge" in the consolidated statements of income. The Corporation's total asbestos-related liability, including defense and processing costs, was $1,490 million at December 31, 2016 , and was included in "Asbestos-related liabilities - current" and "Asbestos-related liabilities - noncurrent" in the consolidated balance sheets. Asbestos-Related Liability at December 31, 2017 In October 2017, the Corporation requested Ankura to review its historical asbestos claim and resolution activity (including asbestos-related defense and processing costs) and determine the appropriateness of updating its December 2016 study. In response to that request, Ankura reviewed and analyzed data through September 30, 2017. In December 2017, Ankura stated that an update of its December 2016 study would not provide a more likely estimate of future events than the estimate reflected in the study and, therefore, the estimate in that study remained applicable. Based on the Corporation's own review of the asbestos claim and resolution activity (including asbestos-related defense and processing costs) and Ankura's response, the Corporation determined that no change to the accrual was required. At December 31, 2017 , the asbestos-related liability for pending and future claims against UCC and Amchem, including future asbestos-related defense and processing costs, was $1,369 million , and approximately 16 percent of the recorded liability related to pending claims and approximately 84 percent related to future claims. Insurance Receivables The Corporation has receivables for insurance recoveries related to its asbestos liability as well as receivables for defense and resolution costs submitted to insurance carriers that have a settlement agreement in place regarding their asbestos-related insurance coverage. The Corporation continues to believe that its recorded receivable for insurance recoveries from all insurance carriers is probable of collection. At December 31, 2017 , the Corporation's receivable for insurance recoveries related to its asbestos liability was $37 million ( $41 million at December 31, 2016 ). Summary The Corporation's management believes the amounts recorded for the asbestos-related liability (including defense and processing costs) reflect reasonable and probable estimates of the liability based on current, known facts. However, future events, such as the number of new claims to be filed and/or received each year and the average cost of defending and disposing of each such claim, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs for the Corporation to be higher or lower than those projected or those recorded. Any such event could result in an increase or decrease in the recorded liability. Because of the uncertainties described above, the Corporation cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing UCC and Amchem. As a result, it is reasonably possible that an additional cost of disposing of asbestos-related claims, including future defense and processing costs, could have a material impact on the Corporation's results of operations and cash flows for a particular period and on the consolidated financial position. Other Litigation While it is not possible at this time to determine with certainty the ultimate outcome of any of the legal proceedings and claims referred to in this filing, management believes that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the results of operations, cash flows and financial position of the Corporation. Purchase Commitments The Corporation has outstanding purchase commitments and various commitments for take-or-pay or throughput agreements. The Corporation was not aware of any purchase commitments that were negotiated as part of a financing arrangement for the facilities that will provide the contracted goods or services or for the costs related to those goods or services at December 31, 2017 and 2016. Operating Leases The Corporation has leases primarily for facilities and distribution equipment. The future minimum rental payments under leases with remaining noncancelable terms in excess of one year are as follows: Minimum Lease Commitments at Dec 31, 2017 In millions 2018 $ 5 2019 4 2020 3 2021 2 2022 1 2023 and thereafter 6 Total $ 21 Rental expenses under leases were $32 million in 2017 , $28 million in 2016 and $29 million in 2015 . |

Retirement Benefits [Abstract] | |
Pension and Other Postretirement Benefits Disclosure [Text Block] | PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS Pension Plans The Corporation has a defined benefit pension plan that covers substantially all employees in the United States. Benefits are based on length of service and the employee's three highest consecutive years of compensation. Employees hired on or after January 1, 2008, earn benefits that are based on a set percentage of annual pay, plus interest. The Corporation also has a non-qualified supplemental pension plan. The Corporation's funding policy is to contribute to the plan when pension laws or economics either require or encourage funding. In 2017 , UCC contributed $162 million to its pension plans including contributions to fund benefit payments for its non-qualified supplemental plan. UCC expects to contribute approximately $42 million to its pension plans in 2018 . The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs are provided below: Pension Plan Assumptions Benefit Obligations at Dec 31 Net Periodic Costs for the Year Ended 2017 2016 2017 2016 2015 Discount rate 3.59 % 4.00 % 4.00 % 4.26 % 3.90 % Rate of compensation increase 4.25 % 4.25 % 4.25 % 4.50 % 4.50 % Expected return on plan assets — — 6.80 % 6.80 % 6.80 % Other Postretirement Benefits The Corporation provides certain health care and life insurance benefits to retired U.S. employees and survivors. The plan provides health care benefits, including hospital, physicians' services, drug and major medical expense coverage and life insurance benefits. The Corporation and the retiree share the cost of these benefits, with the Corporation portion increasing as the retiree has increased years of credited service, although there is a cap on the Corporation portion. The Corporation has the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under this plan. The Corporation funds most of the cost of these health care and life insurance benefits as incurred. In 2017 , UCC did not make any contributions to its other postretirement benefit plan trust. Likewise, UCC does not expect to contribute assets to its other postretirement benefit plan trust in 2018 . The weighted-average assumptions used to determine other postretirement benefit obligations and net periodic benefit costs for the plan are provided in the following table: Plan Assumptions for Other Postretirement Benefits Benefit Obligations at Dec 31 Net Periodic Costs for the Year Ended 2017 2016 2017 2016 2015 Discount rate 3.51 % 3.88 % 3.88 % 4.08 % 3.75 % Health care cost trend rate assumed for next year 6.75 % 7.00 % 7.00 % 7.25 % 7.05 % Rate to which the cost trend rate is assumed to decline (the ultimate health care cost trend rate) 5.00 % 5.00 % 5.00 % 5.00 % 5.00 % Year that the rate reaches the ultimate health care cost trend rate 2025 2025 2025 2025 2020 Assumed health care cost trend rates have a modest effect on the amounts reported for the health care plan. A one percentage point change in assumed health care cost trend rates would have an immaterial impact on service and interest cost and the postretirement benefit obligation. Assumptions The Corporation determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The Corporation's historical experience with the pension fund asset performance is also considered. Effective January 1, 2016, the Corporation adopted the spot rate approach to determine the discount rate utilized to measure the service cost and interest cost components of net periodic pension and other postretirement benefit costs. Under the spot rate approach, the Corporation calculates service cost and interest cost by applying individual spot rates from the Willis Towers Watson U.S. RATE:Link 60-90 corporate yield curve (based on 60th to 90th percentile high-quality corporate bond yields) to the separate expected cash flow components of service cost and interest cost. Prior to 2016, the service and interest cost components were determined based on the single discount rate used to measure the benefit obligation. The Corporation changed to the new method to provide a more precise measure of service and interest costs by improving the correlation between projected benefit cash flows and the discrete spot yield curves. The Corporation accounted for this change as a change in accounting estimate and it was applied prospectively starting in 2016. The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans were based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for the plans are individually discounted at the spot rates under the Willis Towers Watson U.S. RATE:Link 60-90 corporate yield curve (based on 60th to 90th percentile high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. The Corporation utilizes the Society of Actuaries’ mortality tables released in 2014 and a modified version of the generational mortality improvement scale released in 2014 for purposes of measuring the U.S. pension and other postretirement obligations, based on an evaluation of the mortality experience of its pension plans. Summarized information on the Corporation's pension and other postretirement benefit plans is as follows: Change in Projected Benefit Obligations, Plan Assets and Funded Status for all Plans Defined Benefit Pension Plans Other Postretirement Benefits In millions 2017 2016 2017 2016 Change in projected benefit obligations: Benefit obligation at beginning of year $ 4,025 $ 3,993 $ 264 $ 276 Service cost 38 39 1 1 Interest cost 129 131 8 8 Actuarial changes in assumptions and experience 241 155 (23 ) 4 Benefits paid (281 ) (285 ) (26 ) (25 ) Other (2 ) (8 ) — — Benefit obligation at end of year $ 4,150 $ 4,025 $ 224 $ 264 Change in plan assets: Fair value of plan assets at beginning of year $ 3,097 $ 3,173 $ — $ — Actual return on plan assets 331 165 — — Employer contributions 162 52 — — Asset transfers (2 ) (8 ) — — Benefits paid (281 ) (285 ) — — Fair value of plan assets at end of year $ 3,307 $ 3,097 $ — $ — Funded status at end of year $ (843 ) $ (928 ) $ (224 ) $ (264 ) Net amounts recognized in the consolidated balance sheets at Dec 31: Accrued and other current liabilities $ (2 ) $ (2 ) $ (15 ) $ (24 ) Pension and other postretirement benefits - noncurrent (841 ) (926 ) (209 ) (240 ) Net amount recognized $ (843 ) $ (928 ) $ (224 ) $ (264 ) Pretax amounts recognized in accumulated other comprehensive (income) loss at Dec 31: Net loss (gain) $ 2,083 $ 2,035 $ (86 ) $ (69 ) Prior service credit (12 ) (13 ) — — Pretax balance in accumulated other comprehensive (income) loss at end of year $ 2,071 $ 2,022 $ (86 ) $ (69 ) The accumulated benefit obligation for all defined benefit pension plans was $4.1 billion at December 31, 2017 and $4.0 billion at December 31, 2016 .

Plan assets totaled $3.3 billion at December 31, 2017 and $3.1 billion at December 31, 2016 , of which no DowDuPont or Dow common stock was directly held. The Corporation's investment strategy for the plan assets is to manage the assets in relation to the liability in order to pay retirement benefits to plan participants over the life of the plans. This is accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plan. The plan is permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposures and rebalancing the asset allocation. The plan uses value-at-risk, stress testing, scenario analysis and Monte Carlo simulation to monitor and manage both asset risk in the portfolios and surplus risk. Equity securities primarily include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities are primarily U.S. dollar based and include U.S. treasuries and investment grade corporate bonds of companies diversified across industries. Alternative investments primarily include investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types include various insurance contracts; and interest rate, equity and foreign exchange derivative investments and hedges. The Corporation mitigates the credit risk of investments by establishing guidelines with the investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Corporation and the external managers. Credit risk for hedging activity is mitigated by utilizing multiple counterparties, collateral support agreements, and centralized clearing where appropriate. The Northern Trust Collective Government Short Term Investment money market fund is utilized as the sweep vehicle for the pension plan, which from time to time can represent a significant investment. Approximately 35 percent of the liability of the pension plan is covered by a participating group annuity issued by Prudential Insurance Company. The weighted-average target allocation for plan assets of the Corporation's pension plans is summarized as follows: Target Allocation for Plan Assets at Dec 31, 2017 Target Allocation Asset Category Equity securities 23 % Fixed income securities 45 Alternative investments 27 Other 5 Total 100 % Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Corporation believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. For assets classified as Level 1 measurements (measured using quoted prices in active markets), the total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. For assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs such as foreign exchange rates, commodity prices, swap rates, interest rates, and implied volatilities obtained from various market sources. For other assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. For assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers or fund managers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager's investment valuation. Some pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements, and adjusted for estimated earnings and investment activity. These funds are classified as Level 3 due to the significant unobservable inputs inherent in the fair value measurement. The following table summarizes the bases used to measure the Corporation’s pension plan assets at fair value for the years ended December 31, 2017 and 2016 : Basis of Fair Value Measurements Dec 31, 2017 Dec 31, 2016 1 In millions Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Cash and cash equivalents $ 193 $ 153 $ 40 $ — $ 242 $ 237 $ 5 $ — Equity securities: U.S. equity securities $ 374 $ 357 $ 17 $ — $ 253 $ 236 $ 17 $ — Non - U.S. equity securities 472 404 61 7 294 234 54 6 Total equity securities $ 846 $ 761 $ 78 $ 7 $ 547 $ 470 $ 71 $ 6 Fixed income securities: Debt - government-issued $ 873 $ — $ 873 $ — $ 893 $ — $ 893 $ — Debt - corporate-issued 515 — 515 — 512 — 512 — Debt - asset-backed 24 — 24 — 33 — 33 — Total fixed income securities $ 1,412 $ — $ 1,412 $ — $ 1,438 $ — $ 1,438 $ — Alternative investments: Hedge funds $ 292 $ — $ 124 $ 168 $ 341 $ 21 $ 139 $ 181 Private market securities 237 — — 237 214 — — 214 Real estate 360 — — 360 329 — — 329 Derivatives - asset position 6 — 6 — 55 — 55 — Derivatives - liability position (32 ) — (32 ) — (66 ) — (66 ) — Total alternative investments $ 863 $ — $ 98 $ 765 $ 873 $ 21 $ 128 $ 724 Other investments $ (6 ) $ — $ (6 ) $ — $ 18 $ — $ (1 ) $ 19 Subtotal $ 3,308 $ 914 $ 1,622 $ 772 $ 3,118 $ 728 $ 1,641 $ 749 Items to reconcile to fair value of plan assets: Pension trust receivables 2 $ 2 $ 4 Pension trust payables 3 (3 ) (25 ) Total $ 3,307 $ 3,097 1.

As a result of the DowDuPont merger, certain classifications of prior period amounts have been revised to improve comparability with the presentation of Dow and DowDuPont, including the reclassification of $77 million at December 31, 2016 ( $51 million at December 31, 2015) of assets from fixed income securities to alternative investments. Defined Contribution Plans In addition to the qualified defined benefit pension plan, U.S. employees may participate in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which is partially matched by the Corporation. Expense recognized for all defined contribution plans was $21 million in 2017 , $17 million in 2016 and $16 million in 2015 . |

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | FAIR VALUE MEASUREMENTS The Corporation's investments in marketable securities are classified as available-for-sale. Proceeds from sales of available-for-sale securities in 2017 were $2 million ( $2 million in 2016 and $1 million in 2015 ). Portfolio managers regularly review all of the Corporation's holdings to determine if any investments are other-than-temporarily impaired. The analysis includes reviewing the amount of the impairment, as well as the length of time it has been impaired. In addition, specific guidelines for each instrument type are followed to determine if an other-than-temporary impairment has occurred. At December 31, 2017 and 2016 , there were no impairment indicators or circumstances that would result in a material adjustment of these investments. The Corporation's financial instruments are classified as Level 2 measurements. For assets and liabilities classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability, or by using observable market data points of similar, more liquid securities to imply the price. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. Assets that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets in active markets, adjusted for any terms specific to that asset. For all other assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. There were no transfers between Levels 1 and 2 in the years ended December 31, 2017 and 2016 . The following table summarizes the fair value of the Corporation's financial instruments at December 31, 2017 and 2016 : Fair Value of Financial Instruments 2017 2016 In millions Cost Gain Loss Fair Value Cost Gain Loss Fair Value Cash equivalents $ 9 $ — $ — $ 9 $ 7 $ — $ — $ 7 Debt securities 1 $ — $ — $ — $ — $ 2 $ — $ — $ 2 Long-term debt including debt due within one year $ (475 ) $ — $ (129 ) $ (604 ) $ (476 ) $ — $ (95 ) $ (571 ) 1.

Related Party Transactions [Abstract] | |
Related Party Transactions Disclosure [Text Block] | RELATED PARTY TRANSACTIONS The Corporation sells its products to Dow to simplify the customer interface process. Products are sold to and purchased from Dow at market-based prices in accordance with the terms of Dow’s intercompany pricing policies. After each quarter, the Corporation and Dow analyze the pricing used for the sales in that quarter and reach agreement on any necessary adjustments, at which point the prices are final. The Corporation also procures certain commodities and raw materials through a Dow subsidiary and pays a commission to that Dow subsidiary based on the volume and type of commodities and raw materials purchased. The commission expense was included in "Sundry income (expense) - net" in the consolidated statements of income. Purchases from that Dow subsidiary were approximately $1.7 billion in 2017 , $1.4 billion in 2016 and $1.7 billion in 2015 . The Corporation has a master services agreement with Dow whereby Dow provides services including, but not limited to, accounting, legal, treasury (investments, cash management, risk management, insurance), procurement, human resources, environmental, health and safety, and business management for UCC. Under the master services agreement with Dow, general administrative and overhead type services that Dow routinely allocates to various businesses are charged to UCC. The master services agreement cost allocation basis is headcount and includes a 10 percent service fee. This agreement resulted in expense of $33 million in 2017 , $27 million in 2016 and $30 million in 2015 for general administrative and overhead type services and the 10 percent service fee, and was included in "Sundry income (expense) - net" in the consolidated statements of income. The remaining activity-based costs were approximately $78 million in 2017 , $58 million in 2016 and $63 million in 2015 and were included in "Cost of sales" in the consolidated statements of income. Management believes the method used for determining expenses charged by Dow is reasonable. Dow provides these services by leveraging its centralized functional service centers to provide services at a cost that management believes provides an advantage to the Corporation. The monitoring and execution of risk management policies related to interest rate and foreign currency risks, which are based on Dow’s risk management philosophy, are provided as a service to UCC. As part of Dow’s cash management process, UCC is a party to revolving loans with Dow that have interest rates based on LIBOR (London Interbank Offered Rate) with varying maturities. At December 31, 2017 , the Corporation had a note receivable of $1.2 billion ( $1.4 billion at December 31, 2016 ) from Dow under a revolving loan agreement. The Corporation may draw from this note receivable in support of its daily working capital requirements and, as such, the net effect of cash inflows and outflows under this revolving loan agreement is presented in the consolidated statements of cash flows as an operating activity. The Corporation also has a separate revolving credit agreement with Dow that allows the Corporation to borrow or obtain credit enhancements up to an aggregate of $1 billion that matures on December 30, 2018. Dow may demand repayment with a 30-day written notice to the Corporation, subject to certain restrictions. A related collateral agreement provides for the replacement of certain existing pledged assets, primarily equity interests in various subsidiaries and joint ventures, with cash collateral. At December 31, 2017 , $949 million ( $947 million at December 31, 2016 ) was available under the revolving credit agreement. The cash collateral was reported as "Noncurrent receivables from related companies" in the consolidated balance sheets. On a quarterly basis, the Corporation's Board of Directors reviews and determines if there will be a dividend distribution to its parent company and sole shareholder, Dow. The Board takes into consideration the level of earnings and cash flows, among other factors, in determining the amount of the dividend distribution. In 2017 , the Corporation declared and paid dividends totaling $603 million to Dow. In 2016 , the Corporation declared and paid dividends totaling $500 million to Dow. In accordance with the Tax Sharing Agreement between the Corporation and Dow, the Corporation makes payments to Dow to cover the Corporation's estimated federal tax liability; payments were $294 million in 2017 , $415 million in 2016 and $310 million in 2015 . |

Segment Reporting [Abstract] | |
Business and Geographic Areas [Text Block] | BUSINESS AND GEOGRAPHIC REGIONS Dow conducts its worldwide operations through principal product groups, and the Corporation's business activities comprise components of Dow's principal product groups rather than stand-alone operations. The Corporation sells substantially all of its products to Dow in order to simplify the customer interface process at market-based prices in accordance with Dow's intercompany pricing policy. Because there are no separable reportable business segments for the Corporation and no detailed business information is provided to a chief operating decision maker regarding the Corporation's stand-alone operations, the Corporation's results are reported as a single operating segment. Sales are attributed to geographic regions based on customer location; long-lived assets are attributed to geographic regions based on asset location. Sales to external customers and long-lived assets by geographic region were as follows: Geographic Region Information United States Asia Pacific Rest of World Total In millions 2017 Sales to external customers 1 $ 110 $ 21 $ 12 $ 143 Long-lived assets $ 1,341 $ 9 $ 29 $ 1,379 2016 Sales to external customers 1 $ 95 $ 3 $ 10 $ 108 Long-lived assets $ 1,353 $ 10 $ 31 $ 1,394 2015 Sales to external customers 1 $ 70 $ 3 $ 14 $ 87 Long-lived assets $ 1,259 $ 10 $ 32 $ 1,301 1. Of total sales to external customers, sales in Malaysia were approximately 15 percent in 2017, 3 percent in 2016 and 4 percent in 2015, and are included in Asia Pacific. |
SUMMARY OF SIGNIFICANT ACCOUN27
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policy) | 12 Months Ended |
Dec. 31, 2017 | |
Accounting Policies [Abstract] | |
Consolidation, Policy [Policy Text Block] | Except as otherwise indicated by the context, the terms "Corporation" and "UCC" as used herein mean Union Carbide Corporation and its consolidated subsidiaries. The accompanying consolidated financial statements of the Corporation were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Corporation exercises control and, when applicable, entities for which the Corporation has a controlling financial interest. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method. The Corporation is a wholly owned subsidiary of The Dow Chemical Company ("Dow"). In accordance with the accounting requirements for wholly owned subsidiaries, the presentation of earnings per share is not required and therefore is not provided. The Corporation’s business activities comprise components of Dow’s global operations rather than stand-alone operations. Dow conducts its worldwide operations through principal product groups. Because there are no separable reportable business segments for UCC under the accounting guidance related to segment reporting and no detailed business information is provided to a chief operating decision maker regarding the Corporation’s stand-alone operations, the Corporation’s results are reported as a single operating segment. Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017, Dow and E. I. du Pont de Nemours and Company ("DuPont") each merged with subsidiaries of DowDuPont Inc. ("DowDuPont") and, as a result, Dow and DuPont became subsidiaries of DowDuPont (the "Merger"). See Note 3 for additional information. |
Use of Estimates, Policy [Policy Text Block] | The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Corporation's consolidated financial statements include amounts that are based on management's best estimates and judgments. Actual results could differ from those estimates. |
Related Companies, Policy [Policy Text Block] | Transactions with the Corporation's parent company, Dow, and other subsidiaries of Dow and DowDuPont have been reflected as related company transactions in the consolidated financial statements. |
Asbestos-Related Matters - Legal Costs [Policy Text Block] | Accruals for asbestos-related matters, including defense and processing costs, are recorded based on an analysis of claim and resolution activity, defense spending and pending and future claims. These accruals are assessed at each balance sheet date to determine if the asbestos-related liability remains appropriate. Accruals for asbestos-related matters are included in the consolidated balance sheets in "Asbestos-related liabilities - current" and "Asbestos-related liabilities - noncurrent." This accounting policy was added in the fourth quarter of 2016. See Note 14 for additional information. |
Legal Costs, Policy [Policy Text Block] | The Corporation expenses legal costs as incurred, with the exception of defense and processing costs associated with asbestos-related matters. |
Foreign Currency Transactions and Translations Policy [Policy Text Block] | While the Corporation's consolidated subsidiaries are primarily based in the United States, the Corporation has small subsidiaries in Asia Pacific and the rest of the world. For those subsidiaries, the local currency has been primarily used as the functional currency. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in "Accumulated other comprehensive loss" ("AOCL"). Where the U.S. dollar is used as the functional currency, foreign currency gains and losses are reflected in income. |
Environmental Costs, Policy [Policy Text Block] | Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in "Accrued and other current liabilities" and "Other noncurrent obligations" at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets in "Accounts receivable - Other." Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable. |
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and cash equivalents include time deposits and investments with maturities of three months or less at the time of purchase. |
Financial Instruments Accounting Policies [Text Block] | The Corporation calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Corporation uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows. |
Inventory, Policy [Policy Text Block] | Inventories are stated at the lower of cost or net realizable value. The method of determining cost for each subsidiary varies among last-in, first-out ("LIFO"); first-in, first-out ("FIFO"); and average cost, and is used consistently from year to year. The Corporation routinely exchanges and swaps raw materials and finished goods with other companies to reduce delivery time, freight and other transportation costs. These transactions are treated as non-monetary exchanges and are valued at cost. |
Property, Plant and Equipment, Policy [Policy Text Block] | Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income. |
Impairment and Disposal of Long-Lived Assets, Policy [Policy Text Block] | The Corporation evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset's carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value, and depreciation is recognized over the remaining useful life of the assets. |
Intangible Assets, Finite-Lived, Policy [Policy Text Block] | Finite-lived intangible assets such as purchased customer lists, developed technology, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years. |
Investments in Related Companies, Policy [Policy Text Block] | Investments in related companies consist of the Corporation's ownership interests in Dow subsidiaries located in North America and Latin America. The Corporation accounts for these investments using the cost method as it does not have significant influence over the operating and financial policies of these related companies. |
Revenue Recognition, Policy [Policy Text Block] | Substantially all of the Corporation's revenues are generated by sales to Dow. Approximately 99 percent of the Corporation's sales are related to sales of product ( 99 percent in 2016 and 99 percent in 2015 ); the remaining 1 percent is related to the licensing of patents and technology ( 1 percent in 2016 and 1 percent in 2015 ). Revenue for product sales to related companies is recognized as risk and title to the product transfer to the related company, which occurs either at the time production is complete or free on board ("FOB") UCC's manufacturing facility, in accordance with the sales agreement between the Corporation and Dow. Revenue for product sales to trade customers is recognized as risk and title to the product transfer to the customer, which for trade sales, usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. UCC's standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as "Cost of sales" in the consolidated statements of income. Revenue related to the initial licensing of patents and technology is recognized when earned; revenue related to running royalties is recognized according to licensee production levels. |
Severance Costs [Policy Text Block] | Management routinely reviews its operations around the world in an effort to ensure competitiveness across its operations and geographic regions. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under ongoing benefit arrangements. These severance costs are accrued once management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated. |
Business Combinations Policy [Policy Text Block] | The Corporation classifies expenses related to the Merger as integration and separation costs. Merger-related costs include: costs incurred to prepare for and close the Merger, post-Merger integration expenses and costs incurred to prepare for the separation of Dow’s agriculture business, specialty products business and materials science business. This accounting policy was added in the third quarter of 2017 as a result of the Merger. |
Income Tax, Policy [Policy Text Block] | The Corporation accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The Corporation is included in the same consolidated federal income tax group and consolidated income tax return as Dow. The Corporation accounts for its income taxes following the formula in the Dow-UCC Tax Sharing Agreement used to compute the amount due to Dow or UCC for UCC's share of taxable income and tax attributes on the consolidated income tax return. This method generally follows the separate return method. The amounts reported as income taxes payable or receivable represent the Corporation's payment obligation (or refundable amount) to Dow based on a theoretical tax liability calculated on a separate return method. The Corporation recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Corporation accrues for non-income tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested. |

The tax rate for 2016 was favorably impacted by the release of a reserve in excess of the settlement of an uncertain tax position and from the asbestos-related charge. The tax rate for 2015 was favorably impacted by changes in valuation allowances on state income tax attributes. A change in uncertain tax positions in the fourth quarter of 2015 unfavorably impacted the tax rate and resulted in an increase in "Deferred income tax assets" and "Other noncurrent obligations" in the consolidated balance sheets. |
