Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Company and Basis of Presentation	Description of the Company and Basis of Presentation Description of the Company Celanese Corporation and its subsidiaries (collectively, the "Company") is a global technology and specialty materials company. The Company's business involves processing chemical raw materials, such as methanol, carbon monoxide and ethylene, and natural products, including wood pulp, into value-added chemicals, thermoplastic polymers and other chemical-based products. Definitions In this Quarterly Report on Form 10-Q ("Quarterly Report"), the term "Celanese" refers to Celanese Corporation, a Delaware corporation, and not its subsidiaries. The term "Celanese US" refers to the Company's subsidiary, Celanese US Holdings LLC, a Delaware limited liability company, and not its subsidiaries. Basis of Presentation The unaudited interim consolidated financial statements for the three and six months ended June 30, 2017 and 2016 contained in this Quarterly Report were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for all periods presented and include the accounts of the Company, its majority owned subsidiaries over which the Company exercises control and, when applicable, variable interest entities in which the Company is the primary beneficiary. The unaudited interim consolidated financial statements and other financial information included in this Quarterly Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations. In the opinion of management, the accompanying unaudited consolidated balance sheets and related unaudited interim consolidated statements of operations, comprehensive income (loss), cash flows and equity include all adjustments, consisting only of normal recurring items necessary for their fair presentation in conformity with US GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP may have been condensed or omitted in accordance with rules and regulations of the Securities and Exchange Commission ("SEC"). These unaudited interim consolidated financial statements should be read in conjunction with the Company's consolidated financial statements as of and for the year ended December 31, 2016 , filed on February 10, 2017 with the SEC as part of the Company's Annual Report on Form 10-K. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the entire year. In the ordinary course of business, the Company enters into contracts and agreements relative to a number of topics, including acquisitions, dispositions, joint ventures, supply agreements, product sales and other arrangements. The Company endeavors to describe those contracts or agreements that are material to its business, results of operations or financial position. The Company may also describe some arrangements that are not material but in which the Company believes investors may have an interest or which may have been included in a Form 8-K filing. Investors should not assume the Company has described all contracts and agreements relative to the Company's business in this Quarterly Report. For those consolidated ventures in which the Company owns or is exposed to less than 100% of the economics, the outside stockholders' interests are shown as noncontrolling interests. The Company has reclassified certain prior period amounts to conform to the current period's presentation. Estimates and Assumptions The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of Net sales, expenses and allocated charges during the reporting period. Significant estimates pertain to impairments of goodwill, intangible assets and other long-lived assets, purchase price allocations, restructuring costs and other (charges) gains, net, income taxes, pension and other postretirement benefits, asset retirement obligations, environmental liabilities and loss contingencies, among others. Actual results could differ from those estimates. Change in accounting policy regarding share-based compensation Historically, the Company recognized share-based compensation net of estimated forfeitures over the vesting period of the respective grant. Effective January 1, 2017, the Company elected to change its accounting policy to recognize forfeitures as they occur. The new forfeiture policy election was adopted using a modified retrospective approach with a cumulative effect adjustment of $1 million to Retained earnings as of January 1, 2017. See Note 2 - Recent Accounting Pronouncements for further information.

Recent Accounting Pronouncements [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recent Accounting Pronouncements The following table provides a brief description of recent Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"): Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance clarifies the presentation and classification of the components of net periodic benefit costs in the consolidated statement of operations. January 1, 2018. Early adoption is permitted. The Company is currently evaluating the impact of adoption on its financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires the income tax consequences of an intra-entity transfer of assets other than inventory to be recognized when the transfer occurs rather than deferring until an outside sale has occurred. January 1, 2018. Early adoption is permitted. The Company does not expect adoption will have a material impact on its financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. January 1, 2018. Early adoption is permitted. The Company does not expect adoption will have a material impact on its financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The new guidance simplifies several aspects of the accounting for share-based payment transactions, including the timing of recognizing income tax consequences, classification of awards as either equity or liabilities, calculation of compensation expense and classification on the statement of cash flows. January 1, 2017. Early adoption is permitted. The Company adopted the new guidance effective January 1, 2017, as part of the FASB's simplification initiative. The adoption of the new guidance did not have a material impact to the Company. The Company changed its accounting policy regarding the recognition of stock-based compensation expense as part of the adoption ( Note 1 ). In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes the lease guidance under FASB Accounting Standards Codification ("ASC") Topic 840, Leases, resulting in the creation of FASB ASC Topic 842, Leases. The guidance requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. January 1, 2019. Early adoption is permitted. The Company is currently evaluating its population of leases, and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to its accounting for manufacturing and logistics equipment, and real estate operating leases. The Company anticipates recognition of additional assets and corresponding liabilities related to leases upon adoption. The Company plans to adopt the standard effective January 1, 2019. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Since that date, the FASB has issued additional ASUs clarifying certain aspects of ASU 2014-09. The new guidance requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance provides alternative methods of adoption. Subsequent guidance issued after May 2014 did not change the core principle of ASU 2014-09. January 1, 2018. The Company has completed its scoping and preliminary review of its significant revenue contracts to assess the potential impact on its consolidated financial statements and related disclosures. The Company plans to adopt the revenue guidance effective January 1, 2018, although it has not yet selected a transition method. Based on the Company's initial evaluation, though not currently quantified, it currently does not expect the adoption to have a material impact on its consolidated financial statements, as a majority of its revenue transactions are recognized when product is delivered.

Acquisitions, Dispositions and Plant Closures [Abstract]
Acquisitions, Dispositions and Plant Closures	Acquisitions, Dispositions and Plant Closures Acquisitions • Acetate Tow Joint Venture On June 18, 2017, Celanese, through various subsidiaries, entered into an agreement with affiliates of The Blackstone Group L.P. (the "Blackstone Entities") to form a joint venture which combines substantially all of the operations of the Company's cellulose derivatives business and the operations of the Rhodia Acetow cellulose acetate business formerly operated by Solvay S.A. and acquired by the Blackstone Entities on June 1, 2017. The Company's cellulose derivatives operations are included in the Consumer Specialties segment. The combined business will operate under a common governance structure through two separate joint ventures, each of which will be owned ultimately 70 percent and 30 percent by Celanese and the Blackstone Entities, respectively. One venture will primarily be comprised of the US operations being contributed and the other will be comprised of the remaining international operations being contributed. Closing of the transaction is subject to customary closing conditions, including: (i) waiting periods, clearances and/or approvals of the European Union and other jurisdictions requiring antitrust or similar approvals, and (ii) completion of the internal reorganization of the Company's cellulose derivatives business to facilitate the closing and operation of the joint venture post-closing. The agreement may be terminated by Celanese and/or the Blackstone Entities under certain limited circumstances, including if the closing is not consummated within one year of signing, which date may be extended by an additional 90 days, under certain circumstances. Pursuant to the terms of the agreement, once approved and upon closing, the Company is expected to consolidate the joint venture results, subject to the Blackstone Entities' noncontrolling interest. In connection with the agreement, the joint venture obtained commitments for credit facilities aggregating $2.4 billion to be entered into by the joint venture entities at the closing consisting of (i) senior secured ( $135 million ) and senior unsecured ( $65 million ) revolving credit facilities in an aggregate principal amount of $200 million , (ii) senior secured term loan facilities in an aggregate principal amount of $1.0 billion , (iii) a senior unsecured bridge facility in an aggregate principal amount of $800 million , which bridge facility will backstop the proposed issuance of $800 million senior unsecured notes by a joint venture subsidiary, and (iv) a senior unsecured term loan facility in an aggregate principal amount of $400 million . The credit facilities will be guaranteed by certain of the subsidiaries of the respective borrowers; however, only the $65 million senior unsecured revolving credit facility and the $400 million senior unsecured term loan credit facility will be guaranteed by Celanese. Approximately $2.2 billion of the proceeds of the debt financing are expected to be used, in part, to repay certain of the parties' existing indebtedness and a $1.6 billion dividend to the Company. • Nilit Plastics On May 3, 2017, using cash on hand and borrowings under the Company's senior unsecured revolving credit facility, the Company acquired the nylon compounding division of Nilit Group ("Nilit"), an independent producer of high performance nylon resins, fibers and compounds. Celanese acquired the nylon compounding product portfolio, customer agreements and manufacturing, technology and commercial facilities. The acquisition of Nilit increases the Company's global engineered materials product platforms, extends the operational model, technical and industry solutions capabilities and expands project pipelines. The acquisition was accounted for as a business combination and the acquired operations are included in the Advanced Engineered Materials segment. Pro forma financial information since the respective acquisition date has not been provided as the acquisition did not have a material impact on the Company's financial information. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income, market, or cost approach (or a combination thereof). Fair values were determined based on Level 3 inputs including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment and are susceptible to change. The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. However, any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations. The preliminary purchase price allocation for the Nilit acquisition is as follows: As of May 3, 2017 (In $ millions) Cash and cash equivalents 4 Trade receivables - third party and affiliates 21 Inventories 37 Property, plant and equipment, net 36 Intangible assets ( Note 7 ) 104 Goodwill (1) ( Note 7 ) 136 Other assets 11 Total fair value of assets acquired 349 Trade payables - third party and affiliates (8 ) Total debt ( Note 10 ) (12 ) Deferred income taxes (26 ) Benefit obligations (15 ) Other liabilities (2) (45 ) Total fair value of liabilities assumed (106 ) Net assets acquired 243 ______________________________ (1) Goodwill consists of expected revenue and operating synergies resulting from the acquisition. None of the goodwill is deductible for income tax purposes. (2) Includes a $29 million acquisition payment to Nilit Group after the date of close, which was paid as of June 30, 2017. During the six months ended June 30, 2017, transaction related costs of $1 million were expensed as incurred to Selling, general and administrative expenses in the unaudited interim consolidated statements of operations. The amount of pro forma Net earnings (loss) of Nilit included in the Company's unaudited interim consolidated statement of operations was less than 1% (unaudited) of its consolidated Net earnings (loss) had the acquisition occurred as of the beginning of 2017. The amount of Nilit Net earnings (loss) consolidated by the Company since the acquisition date was not material. • SO.F.TER. S.p.A. In December 2016, the Company acquired 100% of the stock of the Forli, Italy based SO.F.TER. S.p.A. ("SOFTER"), a leading thermoplastic compounder. The acquisition of SOFTER increases the Company's global engineered materials product platforms, extends the operational model, technical and industry solutions capabilities and expands project pipelines. The acquisition was accounted for as a business combination and the acquired operations are included in the Advanced Engineered Materials segment. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The purchase price allocation was based on preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. During the six months ended June 30, 2017 , the Company made adjustments to its purchase price allocation which primarily resulted in an increase of $3 million in property, plant and equipment and a reduction to goodwill of the same amount. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.

Ventures and Variable Interest Entities [Abstract]
Ventures and Variable Interest Entities	Ventures and Variable Interest Entities Consolidated Variable Interest Entities The Company has a joint venture, Fairway Methanol LLC ("Fairway"), with Mitsui & Co., Ltd., of Tokyo, Japan ("Mitsui"), in which the Company owns 50% of Fairway, for the production of methanol at the Company's integrated chemical plant in Clear Lake, Texas. The methanol unit utilizes natural gas in the US Gulf Coast region as a feedstock and benefits from the existing infrastructure at the Company's Clear Lake facility. Both Mitsui and the Company supply their own natural gas to Fairway in exchange for methanol tolling under a cost-plus off-take arrangement. The Company determined that Fairway is a variable interest entity ("VIE") in which the Company is the primary beneficiary. Under the terms of the joint venture agreements, the Company provides site services and day-to-day operations for the methanol facility. In addition, the joint venture agreements provide that the Company indemnifies Mitsui for environmental obligations that exceed a specified threshold, as well as an equity option between the partners. Accordingly, the Company consolidates the venture and records a noncontrolling interest for the share of the venture owned by Mitsui. Fairway is included in the Company's Acetyl Intermediates segment. The carrying amount of the assets and liabilities associated with Fairway included in the unaudited consolidated balance sheets are as follows: As of As of (In $ millions) Cash and cash equivalents 24 18 Trade receivables, net - third party & affiliate 10 8 Property, plant and equipment (net of accumulated depreciation - 2017: $70; 2016: $50) 714 734 Intangible assets (net of accumulated amortization - 2017: $2; 2016: $1) 25 26 Other assets 8 9 Total assets (1) 781 795 Trade payables 11 15 Other liabilities (2) 2 2 Total debt 5 5 Deferred income taxes 3 2 Total liabilities 21 24 ______________________________ (1) Assets can only be used to settle the obligations of Fairway. (2) Primarily represents amounts owed by Fairway to the Company for reimbursement of expenditures. Nonconsolidated Variable Interest Entities The Company holds variable interests in entities that supply certain raw materials and services to the Company. The variable interests primarily relate to cost-plus contractual arrangements with the suppliers and recovery of capital expenditures for certain plant assets plus a rate of return on such assets. Liabilities for such supplier recoveries of capital expenditures have been recorded as capital lease obligations. The entities are not consolidated because the Company is not the primary beneficiary of the entities as it does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance. The Company's maximum exposure to loss as a result of its involvement with these VIEs as of June 30, 2017 relates primarily to the recovery of capital expenditures for certain property, plant and equipment. The carrying amount of the assets and liabilities associated with the obligations to nonconsolidated VIEs, as well as the maximum exposure to loss relating to these nonconsolidated VIEs are as follows: As of As of (In $ millions) Property, plant and equipment, net 56 60 Trade payables 29 53 Current installments of long-term debt 10 10 Long-term debt 87 91 Restructuring reserves ( Note 14 ) 21 — Total liabilities 147 154 Maximum exposure to loss 203 240 The difference between the total liabilities associated with obligations to nonconsolidated VIEs and the maximum exposure to loss primarily represents take-or-pay obligations for services included in the Company's unconditional purchase obligations ( Note 18 ).

Environmental Remediation Obligations [Abstract]
Environmental	Environmental The Company is subject to environmental laws and regulations worldwide that impose limitations on the discharge of pollutants into the air and water, establish standards for the treatment, storage and disposal of solid and hazardous wastes, and impose record keeping and notification requirements. Failure to timely comply with these laws and regulations may expose the Company to penalties. The Company believes that it is in substantial compliance with all applicable environmental laws and regulations and engages in an ongoing process of updating its controls to mitigate compliance risks. The Company is also subject to retained environmental obligations specified in various contractual agreements arising from the divestiture of certain businesses by the Company or one of its predecessor companies. The components of environmental remediation reserves are as follows: As of As of (In $ millions) Demerger obligations ( Note 18 ) 25 18 Divestiture obligations ( Note 18 ) 16 16 Active sites 15 16 US Superfund sites 11 11 Other environmental remediation reserves 2 3 Total 69 64 Remediation Due to its industrial history and through retained contractual and legal obligations, the Company has the obligation to remediate specific areas on its own sites as well as on divested, demerger, orphan or US Superfund sites (as defined below). In addition, as part of the demerger agreement between the Company and Hoechst AG ("Hoechst"), a specified portion of the responsibility for environmental liabilities from a number of Hoechst divestitures was transferred to the Company ( Note 18 ). The Company provides for such obligations when the event of loss is probable and reasonably estimable. The Company believes that environmental remediation costs will not have a material adverse effect on the financial position of the Company, but may have a material adverse effect on the results of operations or cash flows in any given period. US Superfund Sites In the US, the Company may be subject to substantial claims brought by US federal or state regulatory agencies or private individuals pursuant to statutory authority or common law. In particular, the Company has a potential liability under the US Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, and related state laws (collectively referred to as "Superfund") for investigation and cleanup costs at certain sites. At most of these sites, numerous companies, including the Company, or one of its predecessor companies, have been notified that the US Environmental Protection Agency ("EPA"), state governing bodies or private individuals consider such companies to be potentially responsible parties ("PRP") under Superfund or related laws. The proceedings relating to these sites are in various stages. The cleanup process has not been completed at most sites, and the status of the insurance coverage for some of these proceedings is uncertain. Consequently, the Company cannot accurately determine its ultimate liability for investigation or cleanup costs at these sites. As events progress at each site for which it has been named a PRP, the Company accrues, as appropriate, a liability for site cleanup. Such liabilities include all costs that are probable and can be reasonably estimated. In establishing these liabilities, the Company considers the contaminants of concern, the potential impact thereof, the relationship of the contaminants of concern to its current and historic operations, its shipment of waste to a site, its percentage of total waste shipped to the site, the types of wastes involved, the conclusions of any studies, the magnitude of any remedial actions that may be necessary and the number and viability of other PRPs. Often the Company joins with other PRPs to sign joint defense agreements that settle, among PRPs, each party's percentage allocation of costs at the site. Although the ultimate liability may differ from the estimate, the Company routinely reviews the liabilities and revises the estimate, as appropriate, based on the most current information available. One such site is the Diamond Alkali Superfund Site, which is comprised of a number of sub-sites, including the Lower Passaic River Study Area, which is the lower 17-mile stretch of the Passaic River ("Lower Passaic River Site"), and the Newark Bay Area. The Company and 70 other companies are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study ("RI/FS") at the Lower Passaic River Site in order to identify the levels of contaminants and potential cleanup actions, including the potential migration of contaminants between the Lower Passaic River Site and the Newark Bay Area. Work on the RI/FS is ongoing, with a goal to complete it in 2018. In March 2016, the EPA issued its final Record of Decision concerning the remediation of the lower 8.3 miles of the Lower Passaic River Site ("Lower 8.3 Miles"). Pursuant to the EPA's Record of Decision, the Lower 8.3 Miles must be dredged bank to bank and an engineered cap must be installed at an EPA estimated cost of approximately $1.4 billion . The Company owned and/or operated facilities in the vicinity of the Lower 8.3 Miles, but has found no evidence that it contributed any of the primary contaminants of concern to the Passaic River. The Company is vigorously defending this matter and currently believes that its ultimate allocable share of the cleanup costs with respect to the Lower Passaic River Site, estimated at less than 1% , will not be material.

During the six months ended June 30, 2017 and 2016 , the Company recorded $4 million and $8 million , respectively, of employee termination benefits primarily related to the Company's ongoing efforts to align its businesses around its core value drivers. A partner in the Company's InfraServ equity affiliate investments exercised an option right, which is currently being disputed, to purchase additional ownership interests in the InfraServ entities from the Company. The purchase of these interests will reduce the Company's ownership interests in InfraServ GmbH & Co. Gendorf KG and InfraServ GmbH & Co. Knapsack KG from 39 percent and 27 percent , to 30 percent and 22 percent , respectively. Accordingly, during the three months ended June 30, 2017 , the Company reduced the carrying value of these investments by $4 million . In addition, the Company has reserved certain amounts for dividends received from the investments since the exercise notification was received. The Company's InfraServ investments are primarily owned by entities included in the Other Activities segment. During the six months ended June 30, 2017 , the Company provided notice of termination of a contract with a key raw materials supplier at its ethanol production unit in Nanjing, China. As a result, the Company recorded an estimated $50 million of plant/office closure costs primarily consisting of a $24 million contract termination charge and an $18 million reduction to its non-income tax receivable. The Nanjing, China ethanol production unit is included in the Company's Acetyl Intermediates segment.

Income Taxes	Income Taxes Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In percentages) Effective income tax rate 14 19 18 19 The lower effective income tax rate for the three months ended June 30, 2017 compared to the same period in 2016 is primarily due to foreign exchange losses in certain jurisdictions where the functional currency differs from the local currency and a release of a tax position due to an audit settlement in Germany. For the six months ended June 30, 2017 , the Company's uncertain tax positions increased $21 million , primarily due to the Nilit acquisition ( Note 3 ) and foreign exchange fluctuations. The Company's US tax returns for the years 2009 through 2012 are currently under audit by the US Internal Revenue Service and certain of the Company's subsidiaries are under audit in jurisdictions outside of the US. In connection with the Company's US federal income tax audit for 2009 and 2010, the Company has received $192 million of proposed pre-tax adjustments related to various intercompany charges. In the event the Company is wholly unsuccessful in its defense, an actual tax assessment would result in the consumption of up to $67 million of prior foreign tax credit carryforwards. The Company believes these proposed adjustments to be without merit and is vigorously defending its position.

Derivative Financial Instruments	Derivative Financial Instruments Net Investment Hedges The Company uses derivative instruments, such as foreign currency forwards, and non-derivative financial instruments, such as foreign currency denominated debt, that may give rise to foreign currency transaction gains or losses to hedge the foreign currency exposure of net investments in foreign operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company's financial assets and liabilities are measured at fair value on a recurring basis as follows: Derivatives. Derivative financial instruments, including commodity swaps and foreign currency forwards and swaps, are valued in the market using discounted cash flow techniques. These techniques incorporate Level 1 and Level 2 fair value measurement inputs such as spot rates and foreign currency exchange rates. These market inputs are utilized in the discounted cash flow calculation considering the instrument's term, notional amount, discount rate and credit risk. Significant inputs to the derivative valuation for commodity swaps and foreign currency forwards and swaps are observable in the active markets and are classified as Level 2 in the fair value measurement hierarchy. Fair Value Measurement Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Total Balance Sheet Classification (In $ millions) As of June 30, 2017 Derivatives Designated as Cash Flow Hedges Commodity swaps — 3 3 Current Other assets Commodity swaps — 1 1 Noncurrent Other assets Derivatives Not Designated as Hedges Foreign currency forwards and swaps — 3 3 Current Other assets Total assets — 7 7 Derivatives Designated as Cash Flow Hedges Foreign currency forwards — (1 ) (1 ) Current Other liabilities Derivatives Not Designated as Hedges Foreign currency forwards and swaps — (6 ) (6 ) Current Other liabilities Total liabilities — (7 ) (7 ) As of December 31, 2016 Derivatives Designated as Cash Flow Hedges Commodity swaps — 5 5 Current Other assets Derivatives Not Designated as Hedges Foreign currency forwards and swaps — 5 5 Current Other assets Total assets — 10 10 Derivatives Not Designated as Hedges Foreign currency forwards and swaps — (3 ) (3 ) Current Other liabilities Total liabilities — (3 ) (3 ) Carrying values and fair values of financial instruments that are not carried at fair value are as follows: Fair Value Measurement Carrying Amount Significant Other Observable Inputs (Level 2) Unobservable Inputs (Level 3) Total (In $ millions) As of June 30, 2017 Cost investments 159 — — — Insurance contracts in nonqualified trusts 47 47 — 47 Long-term debt, including current installments of long-term debt 2,993 2,890 215 3,105 As of December 31, 2016 Cost investments 155 — — — Insurance contracts in nonqualified trusts 49 49 — 49 Long-term debt, including current installments of long-term debt 2,938 2,826 217 3,043 In general, the cost investments included in the table above are not publicly traded and their fair values are not readily determinable; however, the Company believes the carrying values approximate or are less than the fair values. Insurance contracts in nonqualified trusts consist of long-term fixed income securities, which are valued using independent vendor pricing models with observable inputs in the active market and therefore represent a Level 2 fair value measurement. The fair value of long-term debt is based on valuations from third-party banks and market quotations and is classified as Level 2 in the fair value measurement hierarchy. The fair value of obligations under capital leases, which are included in long-term debt, is based on lease payments and discount rates, which are not observable in the market and therefore represents a Level 3 fair value measurement. As of June 30, 2017 and December 31, 2016 , the fair values of cash and cash equivalents, receivables, trade payables, short-term borrowings and the current installments of long-term debt approximate carrying values due to the short-term nature of these instruments. These items have been excluded from the table with the exception of the current installments of long-term debt.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments Guarantees The Company has agreed to guarantee or indemnify third parties for environmental and other liabilities pursuant to a variety of agreements, including asset and business divestiture agreements, leases, settlement agreements and various agreements with affiliated companies. Although many of these obligations contain monetary and/or time limitations, others do not provide such limitations. The Company has accrued for all probable and reasonably estimable losses associated with all known matters or claims. These known obligations include the following: • Demerger Obligations In connection with the Hoechst demerger, the Company agreed to indemnify Hoechst, and its legal successors, for various liabilities under the demerger agreement, including for environmental liabilities associated with contamination arising either from environmental damage in general ("Category A") or under 19 divestiture agreements entered into by Hoechst prior to the demerger ("Category B") ( Note 12 ). The Company's obligation to indemnify Hoechst, and its legal successors, is capped under Category B at €250 million . If and to the extent the environmental damage should exceed €750 million in aggregate, the Company's obligation to indemnify Hoechst and its legal successors applies, but is then limited to 33.33% of the remediation cost without further limitations. Cumulative payments under the divestiture agreements as of June 30, 2017 are $77 million . Most of the divestiture agreements have become time barred and/or any notified environmental damage claims have been partially settled. The Company has also undertaken in the demerger agreement to indemnify Hoechst and its legal successors for (i) 33.33% of any and all Category A liabilities that result from Hoechst being held as the responsible party pursuant to public law or current or future environmental law or by third parties pursuant to private or public law related to contamination and (ii) liabilities that Hoechst is required to discharge, including tax liabilities, which are associated with businesses that were included in the demerger but were not demerged due to legal restrictions on the transfers of such items. These indemnities do not provide for any monetary or time limitations. The Company has not been requested by Hoechst to make any payments in connection with this indemnification. Accordingly, the Company has not made any payments to Hoechst and its legal successors. Based on the Company's evaluation of currently available information, including the lack of requests for indemnification, the Company cannot estimate the Possible Loss for the remaining demerger obligations, if any, in excess of amounts accrued. • Divestiture Obligations The Company and its predecessor companies agreed to indemnify third-party purchasers of former businesses and assets for various pre-closing conditions, as well as for breaches of representations, warranties and covenants. Such liabilities also include environmental liability, product liability, antitrust and other liabilities. These indemnifications and guarantees represent standard contractual terms associated with typical divestiture agreements and, other than environmental liabilities, the Company does not believe that they expose the Company to any significant risk ( Note 12 ). The Company has divested numerous businesses, investments and facilities through agreements containing indemnifications or guarantees to the purchasers. Many of the obligations contain monetary and/or time limitations, which extend through 2037 . The aggregate amount of outstanding indemnifications and guarantees provided for under these agreements is $124 million as of June 30, 2017 . Other agreements do not provide for any monetary or time limitations. Based on the Company's evaluation of currently available information, including the number of requests for indemnification or other payment received by the Company, the Company cannot estimate the Possible Loss for the remaining divestiture obligations, if any, in excess of amounts accrued. Purchase Obligations In the normal course of business, the Company enters into various purchase commitments for goods and services. The Company maintains a number of "take-or-pay" contracts for purchases of raw materials, utilities and other services. Certain of the contracts contain a contract termination buy-out provision that allows for the Company to exit the contracts for amounts less than the remaining take-or-pay obligations. Additionally, the Company has other outstanding commitments representing maintenance and service agreements, energy and utility agreements, consulting contracts and software agreements. As of June 30, 2017 , the Company had unconditional purchase obligations of $1.9 billion , which extend through 2036 . Contingencies The Company is involved in legal and regulatory proceedings, lawsuits, claims and investigations incidental to the normal conduct of business, relating to such matters as product liability, land disputes, commercial contracts, employment, antitrust or competition compliance, intellectual property, workers' compensation, chemical exposure, asbestos exposure, taxes, trade compliance, prior acquisitions and divestitures, claims of legacy stockholders, past waste disposal practices and release of chemicals into the environment. The Company is actively defending those matters where the Company is named as a defendant and, based on the current facts, does not believe the outcomes from these matters would be material to the Company's results of operations, cash flows or financial position. European Commission In May 2017, the Company learned that the European Commission has opened a competition law investigation involving certain subsidiaries of the Company with respect to certain raw material purchases. The Company is cooperating with the European Commission. Because of the early stage of the investigation and the many uncertainties and variables involved, the Company is unable at this time to determine the outcome of this investigation and whether, and in what amount, any potential fines would be assessed.

Consolidating Guarantor Financial Information [Abstract]
Consolidating Guarantor Financial Information	Consolidating Guarantor Financial Information The Senior Notes were issued by Celanese US ("Issuer") and are guaranteed by Celanese Corporation ("Parent Guarantor") and the Subsidiary Guarantors ( Note 10 ). The Issuer and Subsidiary Guarantors are 100% owned subsidiaries of the Parent Guarantor. The Parent Guarantor and Subsidiary Guarantors have guaranteed the Notes fully and unconditionally and jointly and severally. For cash management purposes, the Company transfers cash between the Parent Guarantor, Issuer, Subsidiary Guarantors and non-guarantors through intercompany financing arrangements, contributions or declaration of dividends between the respective parent and its subsidiaries. The transfer of cash under these activities facilitates the ability of the recipient to make specified third-party payments for principal and interest on the Company's outstanding debt, Common Stock dividends and Common Stock repurchases. The unaudited interim consolidating statements of cash flows for the six months ended June 30, 2017 and 2016 present such intercompany financing activities, contributions and dividends consistent with how such activity would be presented in a stand-alone statement of cash flows. The Company has not presented separate financial information and other disclosures for each of its Subsidiary Guarantors because it believes such financial information and other disclosures would not provide investors with any additional information that would be material in evaluating the sufficiency of the guarantees. The unaudited interim consolidating financial statements for the Parent Guarantor, the Issuer, the Subsidiary Guarantors and the non-guarantors are as follows: CELANESE CORPORATION AND SUBSIDIARIES UNAUDITED INTERIM CONSOLIDATING STATEMENT OF OPERATIONS Three Months Ended June 30, 2017 Parent Guarantor Issuer Subsidiary Guarantors Non- Guarantors Eliminations Consolidated (In $ millions) Net sales — — 563 1,222 (275 ) 1,510 Cost of sales — — (457 ) (966 ) 280 (1,143 ) Gross profit — — 106 256 5 367 Selling, general and administrative expenses — — (26 ) (70 ) — (96 ) Amortization of intangible assets — — (1 ) (4 ) — (5 ) Research and development expenses — — (7 ) (10 ) — (17 ) Other (charges) gains, net — — (1 ) (2 ) — (3 ) Foreign exchange gain (loss), net — — — (4 ) — (4 ) Gain (loss) on disposition of businesses and assets, net — — (2 ) — — (2 ) Operating profit (loss) — — 69 166 5 240 Equity in net earnings (loss) of affiliates 231 233 163 34 (623 ) 38 Interest expense — (6 ) (24 ) (8 ) 8 (30 ) Refinancing expense — — — — — — Interest income — 6 1 2 (8 ) 1 Dividend income -

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Estimates and Assumptions, Policy [Policy Text Block]	Estimates and Assumptions The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of Net sales, expenses and allocated charges during the reporting period. Significant estimates pertain to impairments of goodwill, intangible assets and other long-lived assets, purchase price allocations, restructuring costs and other (charges) gains, net, income taxes, pension and other postretirement benefits, asset retirement obligations, environmental liabilities and loss contingencies, among others. Actual results could differ from those estimates.
Accounting Changes [Text Block]	Change in accounting policy regarding share-based compensation Historically, the Company recognized share-based compensation net of estimated forfeitures over the vesting period of the respective grant. Effective January 1, 2017, the Company elected to change its accounting policy to recognize forfeitures as they occur. The new forfeiture policy election was adopted using a modified retrospective approach with a cumulative effect adjustment of $1 million to Retained earnings as of January 1, 2017. See Note 2 - Recent Accounting Pronouncements for further information.

Variable Interest Entity, Not Primary Beneficiary [Member]
Variable Interest Entity [Line Items]
Schedule of Variable Interest Entities	The Company holds variable interests in entities that supply certain raw materials and services to the Company. The variable interests primarily relate to cost-plus contractual arrangements with the suppliers and recovery of capital expenditures for certain plant assets plus a rate of return on such assets. Liabilities for such supplier recoveries of capital expenditures have been recorded as capital lease obligations. The entities are not consolidated because the Company is not the primary beneficiary of the entities as it does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance. The Company's maximum exposure to loss as a result of its involvement with these VIEs as of June 30, 2017 relates primarily to the recovery of capital expenditures for certain property, plant and equipment. The carrying amount of the assets and liabilities associated with the obligations to nonconsolidated VIEs, as well as the maximum exposure to loss relating to these nonconsolidated VIEs are as follows: As of As of (In $ millions) Property, plant and equipment, net 56 60 Trade payables 29 53 Current installments of long-term debt 10 10 Long-term debt 87 91 Restructuring reserves ( Note 14 ) 21 — Total liabilities 147 154 Maximum exposure to loss 203 240 The difference between the total liabilities associated with obligations to nonconsolidated VIEs and the maximum exposure to loss primarily represents take-or-pay obligations for services included in the Company's unconditional purchase obligations ( Note 18 ).
