Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Interim Financial Statements The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the company’s Annual Report on Form 10-K for the year ended December 31, 2017, collectively referred to as the “2017 Annual Report”. The interim Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained. Principles of Consolidation and Basis of Presentation DowDuPont Inc. ("DowDuPont") was formed on December 9, 2015 to effect an all-stock, merger of equals strategic combination between The Dow Chemical Company ("Dow") and DuPont (the "Merger Transaction"). On August 31, 2017 at 11:59 pm ET, (the "Merger Effectiveness Time") pursuant to the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), Dow and DuPont each merged with wholly owned subsidiaries of DowDuPont ("Mergers") and, as a result of the Mergers, Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the Merger Agreement. DowDuPont intends to pursue, subject to certain customary conditions, including, among others, the effectiveness of registration statements filed with the Securities and Exchange Commission and approval by the Board of Directors of DowDuPont, the separation of the combined company's agriculture business, specialty products business and materials science business through a series of tax-efficient transactions (collectively, the "Intended Business Separations"). For purposes of DowDuPont's financial statement presentation, Dow was determined to be the accounting acquirer in the Merger and DuPont's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. In connection with the Merger and the related accounting determination, DuPont has elected to apply push-down accounting and reflect in its financial statements the fair value of its assets and liabilities. DuPont's interim Consolidated Financial Statements for periods following the close of the Merger are labeled “Successor” and reflect DowDuPont’s basis in the fair values of the assets and liabilities of DuPont. All periods prior to the closing of the Merger reflect the historical accounting basis in DuPont's assets and liabilities and are labeled “Predecessor.” The interim Consolidated Financial Statements and footnotes include a black line division between the columns titled "Predecessor" and "Successor" to signify that the amounts shown for the periods prior to and following the Merger are not comparable. See Note 3 for additional information on the Merger. Transactions between DuPont and DowDuPont, Dow and their affiliates and other associated companies are reflected in the Successor consolidated financial statements and disclosed as related party transactions when material. Related party transactions with Dow and DowDuPont are included in Note 7 . As a condition of the regulatory approval for the Merger Transaction, the company was required to divest certain assets related to its crop protection business and research and development ("R&D") organization, specifically the company’s Cereal Broadleaf Herbicides and Chewing Insecticides portfolios, including Rynaxypyr ® , Cyazypyr ® and Indoxacarb as well as the crop protection R&D pipeline and organization, excluding seed treatment, nematicides, and late-stage R&D programs. On March 31, 2017, the company entered into a definitive agreement (the "FMC Transaction Agreement") with FMC Corporation ("FMC"). Under the FMC Transaction Agreement, FMC would acquire the crop protection business and R&D assets that DuPont was required to divest in order to obtain European Commission ("EC") approval of the Merger Transaction as described above, (the "Divested Ag Business") and DuPont agreed to acquire certain assets relating to FMC’s Health and Nutrition segment, excluding its Omega-3 products (the "H&N Business") (collectively, the "FMC Transactions"). On November 1, 2017, the company completed the FMC Transactions through the disposition of the Divested Ag Business and the acquisition of the H&N Business. The sale of the Divested Ag Business meets the criteria for discontinued operations and as such, results of operations are presented as discontinued operations and have been excluded from continuing operations for all periods presented. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The comprehensive income and cash flows related to the Divested Ag Business have not been segregated and are included in the interim Consolidated Statements of Comprehensive Income and interim Condensed Consolidated Statements of Cash Flows, respectively, for all periods presented. Amounts related to the Divested Ag Business are consistently included or excluded from the Notes to the interim Consolidated Financial Statements based on the respective financial statement line item. See Note 4 for additional information. Certain reclassifications of prior year's data have been made to conform to current year's presentation. As described in Note 2 , effective January 1, 2018, the company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. In conjunction with the adoption of this ASU, the company retrospectively reclassified the non-service components of net periodic benefit cost in the interim Consolidated Statements of Operations, as described in Note 2 . Significant Accounting Policies The company has updated it revenue recognition policy since issuance of its 2017 Annual Report as a result of the adoption of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) in the first quarter 2018. See Notes 2 and 5 for additional information. See Note 1, "Summary of Significant Accounting Policies," in the 2017 Annual Report for more information on DuPont's other significant accounting policies. Revenue The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To determine revenue recognition for the arrangements that the company determines are within the scope of Topic 606, the company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 5 for additional information on revenue recognition. Changes in Accounting and Reporting Within the Successor period, DuPont made the following changes in accounting and reporting to harmonize its accounting and reporting with DowDuPont. Within the Successor period of the interim Consolidated Statements of Operations: • Included royalty income within net sales. In the Predecessor periods, royalty income is included within sundry income - net. • Eliminated the other operating charges line item. In the Successor period, a majority of these costs are included within cost of goods sold. These costs are also included in selling, general and administrative expenses and amortization of intangibles in the Successor period. • Presented amortization of intangibles as a separate line item. In the Predecessor periods, amortization is included within selling, general and administrative expenses, other operating charges, and research and development expenses. • Presented integration and separation costs as a separate line item. In the Predecessor periods, these costs are included within selling, general and administrative expenses. • Included interest accrued related to unrecognized tax benefits within the provision for income taxes on continuing operations. In the Predecessor period, interest accrued related to unrecognized tax benefits is included within sundry income - net. Within the Successor period of the interim Condensed Consolidated Statements of Cash Flows: • Included foreign currency exchange contract settlements within cash flows from operating activities, regardless of hedge accounting qualification. In the Predecessor period, DuPont reflected non-qualified hedge programs, specifically forward contracts, options and cash collateral activity, within cash flows from investing activities. In the Predecessor period, DuPont reflected cash flows from qualified hedge programs within the line item to which the program related (i.e., revenue hedge cash flows presented within changes from accounts receivable).

Recent Accounting Guidance

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which was further updated in March, April, May and December 2016, as well as September and November 2017. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The new standard resulted in additional disclosure requirements to describe the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The standard permits the use of either the retrospective or modified retrospective (cumulative-effect) transition method of adoption. The company adopted this standard in the first quarter of 2018 and applied the modified retrospective transition method to contracts not completed at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting under Topic 605 (Revenue Recognition). The company recognized the cumulative effect of applying the new revenue standard as an adjustment to the opening balance of retained earnings in the beginning of 2018. See Note 5 for additional disclosures regarding the company's contracts with customers. In accordance with Topic 606, the disclosure of the impact of adoption to the company's interim Condensed Consolidated Balance Sheet was as follows: (In millions, except per share amounts) As Reported December 31, 2017 Effect of Adoption of ASU 2014-09 Updated January 1, 2018 Current assets Accounts and notes receivable - net $ 5,239 $ 65 $ 5,304 Inventories 8,633 (53 ) 8,580 Other current assets 981 115 1,096 Deferred income taxes $ 480 $ 1 $ 481 Liabilities and Equity Current liabilities Accounts payable $ 4,831 $ (3 ) $ 4,828 Accrued and other current liabilities 4,384 120 4,504 Deferred income tax liabilities $ 5,836 $ 3 $ 5,839 Retained earnings $ 175 $ 8 $ 183 The most significant changes as a result of adopting ASU No. 2014-09 relate to the reclassification of the company's return assets and refund liabilities in the agriculture product line on the interim Condensed Consolidated Balance Sheets. Under previous guidance, the company accrued the amount of expected product returns as a reduction of net sales and a reduction of accounts and notes receivable - net, and the value associated with the products expected to be recovered in inventory along with a corresponding reduction in cost of goods sold. Under Topic 606, the company now separately presents the amount of expected product returns as refund liabilities, included in accrued and other current liabilities, and the products expected to be recovered as return assets, included in other current assets in the consolidated balance sheets. The reclassification of return assets and refund liabilities was $61 million and $119 million , respectively, at January 1, 2018. The effect on the interim Consolidated Statements of Operations and the interim Condensed Consolidated Statement of Cash Flows was not material. The following table summarizes the effects of adopting the new accounting standard related to revenue recognition on the company's interim Condensed Consolidated Balance Sheet: March 31, 2018 (In millions, except per share amounts) As Reported Effect of Change Balance without Adoption of Topic 606 Current assets Accounts and notes receivable - net $ 7,147 $ (205 ) $ 6,942 Inventories 7,901 111 8,012 Other current assets 1,287 (168 ) 1,119 Deferred income taxes $ 330 $ (1 ) $ 329 Liabilities and Equity Current liabilities Accrued and other current liabilities $ 4,133 $ (258 ) $ 3,875 Deferred income tax liabilities $ 5,669 $ (2 ) $ 5,667 Accumulated deficit $ (881 ) $ (3 ) $ (884 ) In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The new guidance makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The new guidance requires adoption on a retrospective basis unless it is impracticable to apply, in which case the company would be required to apply the amendments prospectively as of the earliest date practicable. The company adopted this standard on January 1, 2018 and there was no material impact. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than when the asset is sold to an outside party. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The new guidance requires adoption on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The company adopted this standard on January 1, 2018 and there was no adjustment to retained earnings. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash (a consensus of the FASB Emerging Issues Task Force), which clarifies how entities should present restricted cash and restricted cash equivalents in the statement of cash flows, and, as a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. An entity with a material balance of restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The company adopted this standard on January 1, 2018. See the interim Condensed Consolidated Statement of Cash Flows for the new presentation of restricted cash as well as Note 8 for a reconciliation of cash, cash equivalents and restricted cash (included in other current assets) presented on the interim Condensed Consolidated Balance Sheets to the total cash, cash equivalents and restricted cash presented in the interim Condensed Consolidated Statements of Cash Flows. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business. The new guidance narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities (collectively, the "set") is not a business. To be considered a business, the set would need to include an input and a substantive process that together significantly contribute to the ability to create outputs, as defined by the ASU. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, and should be applied prospectively. Early adoption is permitted. The company adopted this standard on January 1, 2018 and will apply it prospectively to all applicable transactions after the adoption date. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance requires registrants to present the service cost component of net periodic benefit cost in the same income statement line item or items as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Registrants will present the other components of net periodic benefit cost separately from the service cost component; and, the line item or items used in the income statement to present the other components of net periodic benefit cost must be disclosed. The new standard must be adopted retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement, and prospectively for the capitalization of the service cost component of net periodic benefit cost in assets. The company adopted this guidance on January 1, 2018, and will record the other components of net periodic benefit cost in sundry income - net. The following table summarizes the reclassification of those costs from cost of goods sold, research and development expense, and selling, general and administrative expenses to sundry income - net in the interim Consolidated Statements of Operations: Summary of Changes to the interim Consolidated Statement of Operations For the Three Months Ended March 31, 2017 (Predecessor) (in millions) As reported 1 Effect of Change Updated Cost of goods sold $ 4,209 $ (57 ) $ 4,152 Research and development expense $ 384 $ (16 ) $ 368 Selling, general and administrative expenses $ 1,221 $ (31 ) $ 1,190 Sundry income - net $ 306 $ (104 ) $ 202 1. Includes adjustments for discontinued operations. Accounting Guidance Issued But Not Adopted as of March 31, 2018 In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged items in the financial statements. For cash flow and net investment hedges existing as of the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year in which an entity adopts. Presentation and disclosure guidance is required to be adopted prospectively. The new standard is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted in any interim period. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption. The company will early adopt the new guidance in the second quarter of 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under the new guidance will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new leasing standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The company is currently evaluating the impact of adopting this guidance on the Consolidated Financial Statements and related disclosures. The company is the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	BUSINESS COMBINATIONS Merger with Dow Upon completion of the Merger, (i) each share of common stock, par value $0.30 per share, of the company (the "DuPont Common Stock") was converted into the right to receive 1.2820 fully paid and non-assessable shares of DowDuPont common stock, par value $0.01 per share, ("DowDuPont Common Stock"), in addition to cash in lieu of any fractional shares of DowDuPont Common Stock, and (ii) each share of DuPont Preferred Stock— $4.50 Series and DuPont Preferred Stock— $3.50 Series (collectively "DuPont Preferred Stock") issued and outstanding immediately prior to the Merger Effectiveness Time remains issued and outstanding and was unaffected by the Merger. As provided in the Merger Agreement, at the Merger Effectiveness Time, all options relating to shares of DuPont Common Stock that were outstanding immediately prior to the effective time of the Merger were generally automatically converted into options relating to shares of DowDuPont Common Stock and all restricted stock units and performance based restricted stock units relating to shares of DuPont Common Stock that were outstanding immediately prior to the effective time of the Mergers were generally automatically converted into restricted stock units relating to shares of DowDuPont Common Stock, in each case, after giving effect to appropriate adjustments to reflect the Mergers and otherwise generally on the same terms and conditions as applied under the applicable plans and award agreements immediately prior to the Merger Effectiveness Time. Prior to the Merger, shares of DuPont Common Stock were registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended and listed on the New York Stock Exchange (the “NYSE”). As a result of the Merger, on August 31, 2017 , the company requested that the NYSE withdraw the shares of DuPont Common Stock from listing on the NYSE and filed a Form 25 with the U.S. Securities and Exchange Commission ("SEC") to report that DuPont Common Stock is no longer listed on the NYSE. DuPont continues to have preferred stock outstanding and it remains listed on the NYSE. DowDuPont Common Stock is listed and trades on the NYSE, ticker symbol DWDP. As a condition of the regulatory approval of the Merger, DuPont was required to divest a portion of its crop protection product line, including certain research and development capabilities. See Note 4 for additional information. Preliminary Allocation of Purchase Price Based on an evaluation of the provisions of Accounting Standards Codification ("ASC") 805, "Business Combinations" ("ASC 805"), Dow was determined to be the accounting acquirer in the Merger. DowDuPont has applied the acquisition method of accounting with respect to the assets and liabilities of DuPont, which have been measured at fair value as of the date of the Merger. In connection with the Merger and the related accounting determination, DuPont has elected to apply push-down accounting and reflect in its financial statements the fair value of assets and liabilities. Such fair values have been reflected in the Successor Consolidated Financial Statements. DuPont's assets and liabilities were measured at estimated fair values as of the Merger Effectiveness Time, primarily using Level 3 inputs. Estimates of fair value represent management's best estimate which require a complex series of judgments about future events and uncertainties. Third-party valuation specialists were engaged to assist in the valuation of these assets and liabilities. The total fair value of consideration transferred for the Merger was $74,680 million . Total consideration is comprised of the equity value of the DowDuPont shares as of the Merger Effectiveness Time that were issued in exchange for DuPont shares, the cash value for fractional shares, and the portion of DuPont's share awards and share options earned as of the Merger Effectiveness Time. The following table summarizes the fair value of consideration exchanged as a result of the Merger: (In millions, except exchange ratio) DuPont Common Stock outstanding as of the Merger Effectiveness Time 868.3 DuPont exchange ratio 1.2820 DowDuPont Common Stock issued in exchange for DuPont Common Stock 1,113.2 Fair value of DowDuPont Common Stock issued 1 $ 74,195 Fair value of DowDuPont equity awards issued in exchange for outstanding DuPont equity awards 2 485 Total consideration $ 74,680 1. Amount was determined based on the price per share of Dow Common Stock of $66.65 on August 31, 2017. 2. Represents the fair value of replacement awards issued for DuPont's equity awards outstanding immediately before the Merger and attributable to the service periods prior to the Merger. The previous DuPont equity awards were converted into the right to receive 1.2820 shares of DowDuPont Common Stock. The acquisition method of accounting requires, among other things, that identifiable assets acquired and liabilities assumed be recognized on the balance sheet at their respective fair value as of the acquisition date. In determining the fair value, DowDuPont utilized various forms of the income, cost and market approaches depending on the asset or liability being fair valued. The estimation of fair value required significant judgments related to future net cash flows (including net sales, cost of products sold, selling and marketing costs, and working capital/contributory asset charges), discount rates reflecting the risk inherent in each cash flow stream, competitive trends, market comparables and other factors. Inputs were generally determined by taking into account historical data, supplemented by current and anticipated market conditions, and growth rates. The table below presents the preliminary fair value that was allocated to DuPont's assets and liabilities based upon fair values as determined by DowDuPont. The valuation process to determine the fair values is not yet complete. DuPont estimated the preliminary fair value of acquired assets and liabilities as of the Merger Effectiveness Time based on information currently available and continues to adjust those estimates upon refinement of market participant assumptions for integrating businesses, finalization of tax returns in the pre-merger period and application of push-down accounting at the subsidiary level. In the first quarter of 2018, DowDuPont made measurement period adjustments to reflect facts and circumstances in existence as of the Merger Effectiveness Time. These adjustments primarily included a $282 million increase in goodwill, a $98 million decrease in property, plant, and equipment, an $80 million decrease in indefinite-lived trademarks and trade names and customer-related assets, a $56 million increase in noncontrolling interests, a $28 million decrease in investments in nonconsolidated affiliates and a $16 million decrease in assets held for sale. The preliminary fair values are substantially complete with the exception of identifiable intangible assets, property, plant, and equipment, income taxes and goodwill. As DuPont finalizes the fair values of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period, but no later than one year from the date of the Merger. DuPont will reflect measurement period adjustments, if any, in the period in which the adjustments are recognized. Final determination of the fair values may result in further adjustments to the values presented in the following table.

These costs to date primarily have consisted of financial advisory, information technology, legal, accounting, consulting, and other professional advisory fees associated with the preparation and execution of activities related to the Merger and the Intended Business Separations. These costs are recorded within integration and separation costs in the Successor period and within selling, general and administrative expenses in the Predecessor period within the interim Consolidated Statements of Operations. Successor Predecessor (In millions) Three Months Ended March 31, 2018 Three Months Ended March 31, 2017 Integration and separation costs $ 255 Selling, general and administrative expenses $ 170 H&N Business On November 1, 2017, the company completed the FMC Transactions through the acquisition of the H&N Business and the divestiture of the Divested Ag Business. The acquisition is being integrated into the nutrition and health product line to enhance DuPont’s position as a leading provider of sustainable, bio-based food ingredients and allow for expanded capabilities in the pharma excipients space. The company accounted for the acquisition in accordance with ASC 805, which requires the assets acquired and liabilities assumed to be recognized on the balance sheet at their fair values as of the acquisition date. The purchase accounting and purchase price allocation for the H&N Business are substantially complete. However, the company continues to refine the preliminary valuation of certain acquired assets, such as intangibles, deferred income taxes, and property, plant and equipment, which could impact the amount of residual goodwill recorded. The company will finalize the amounts recognized as it obtains the information necessary to complete the analysis, but no later than one year from the date of the acquisition. The preliminary fair value allocated to the assets acquired and liabilities assumed for the H&N Business at November 1, 2017 was $1,970 million . There were no material updates to the purchase accounting and purchase price allocation for the three months ended March 31, 2018. For additional information regarding the acquisition of the H&N Business, see Note 3, "Business Combinations," in the 2017 Annual Report.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	DIVESTITURES AND OTHER TRANSACTIONS Merger Remedy - Divested Ag Business On March 31, 2017, the company and FMC entered into the FMC Transaction Agreement. Under the FMC Transaction Agreement, and effective upon the closing of the transaction on November 1, 2017, FMC acquired the Divested Ag Business that DuPont was required to divest in order to obtain EC approval of the Merger Transaction and DuPont acquired the H&N Business. See further discussion of the FMC Transactions in Note 1 . The sale of the Divested Ag Business meets the criteria for discontinued operations and as such, earnings are included within (loss) income from discontinued operations after income taxes for all periods presented. For the three months ended March 31, 2018, the company recorded a loss from discontinued operations before income taxes related to the Divested Ag Business of $10 million ( $5 million after tax). The following table summarizes the results of operations of the Divested Ag Business presented as discontinued operations for the three months ended March 31, 2017: Predecessor (In millions) Three Months Ended March 31, 2017 Net sales $ 424 Cost of goods sold 162 Other operating charges 4 Research and development expenses 32 Selling, general and administrative expenses 39 Income from discontinued operations before income taxes 187 Provision for income taxes 27 Income from discontinued operations after income taxes $ 160 The following table presents depreciation and capital expenditures of the discontinued operations related to the Divested Ag Business: Predecessor (In millions) Three Months Ended March 31, 2017 Depreciation $ 8 Capital expenditures $ 4 Food Safety Diagnostic Sale In February 2017, the company completed the sale of global food safety diagnostics to Hygiena LLC. The sale resulted in a pre-tax gain of $162 million ( $86 million net of tax). The gain was recorded in sundry income - net in the company's interim Consolidated Statement of Operations for the three months ended March 31, 2017 . Performance Chemicals On July 1, 2015, DuPont completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company (the "Separation"). In connection with the Separation, the company and The Chemours Company ("Chemours") entered into a Separation Agreement (the "Separation Agreement"). Pursuant to the Separation Agreement and the amendment to the Separation Agreement, as discussed below, Chemours indemnifies DuPont against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In 2017, DuPont and Chemours amended the Separation Agreement to provide for a limited sharing of potential future perfluorooctanoic acid (“PFOA”) liabilities for a period of five years beginning July 6, 2017. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At March 31, 2018 , the indemnified assets are $82 million within accounts and notes receivable - net and $332 million within other assets along with the corresponding liabilities of $82 million within accrued and other current liabilities and $332 million within other noncurrent obligations in the interim Condensed Consolidated Balance Sheet. See Note 14 for further discussion of the amendment to the Separation Agreement and certain litigation and environmental matters indemnified by Chemours. Loss from discontinued operations after income taxes for the three months ended March 31, 2017 includes a charge of $335 million ( $224 million net of tax) in connection with the PFOA multi-district litigation settlement. See Note 14 for further discussion.

Revenue (Notes)

Revenue (Notes)	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	REVENUE Revenue Recognition Products Substantially all of DuPont's revenue is derived from product sales. Product sales consist of sales of DuPont's products to supply manufacturers, distributors, and farmers. DuPont considers purchase orders, which in some cases are governed by master supply agreements, to be a contract with a customer. Contracts with customers are considered to be short-term when the time between order confirmation and satisfaction of the performance obligations is equal to or less than one year. Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms for contracts related to product lines other than agriculture generally average 30 to 60 days after invoicing, depending on business and geography. Payment terms for agriculture product line contracts are generally less than one year from invoicing. The company elected the practical expedient and will not adjust the promised amount of consideration for the effects of a significant financing component when DuPont expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. The company has elected to recognize shipping and handling activities when control has transferred to the customer as an expense in cost of goods sold. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, DuPont elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less. The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates for variable consideration are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, DuPont allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances. Licenses of Intellectual Property DuPont enters into licensing arrangements with customers under which it licenses its intellectual property, such as patents and trademarks. Revenue from the majority of intellectual property licenses is derived from sales-based royalties. The company estimates the expected amount of sales-based royalties based on historical sales by customer. Revenue for licensing agreements that contain sales-based royalties is recognized at the later of (i) when the subsequent sale occurs or (ii) when the performance obligation to which some or all of the royalty has been allocated is satisfied. Contract Balances Contract liabilities primarily reflect deferred revenue from prepayments under agriculture product line contracts with customers where the company receives advance payments for products to be delivered in future periods. DuPont classifies deferred revenue as current or noncurrent based on the timing of when the company expects to recognize revenue. Contract assets primarily include amounts related to contractual rights to consideration for completed performance not yet invoiced within the industrial biosciences product line. Accounts receivable are recorded when the right to consideration becomes unconditional. Contract Balances March 31, 2018 Topic 606 Adjustments January 1, 2018 December 31, 2017 (In millions) Accounts and notes receivable - trade 1 $ 5,699 $ 87 $ 3,976 Contract assets - current 2 $ 57 $ 54 $ — Deferred revenue - current 3 $ 1,904 $ 2 $ 2,014 Deferred revenue - noncurrent 4 $ 49 $ — $ 48 1. Included in accounts and notes receivable - net in the Consolidated Balance Sheets. 2. Included in other current assets in the Consolidated Balance Sheets. 3. Included in accrued and other current liabilities in the Consolidated Balance Sheets. 4. Included in other noncurrent obligations in the Consolidated Balance Sheets. The decrease in deferred revenue from December 31, 2017 to March 31, 2018 was primarily due to the timing of agriculture product line seed deliveries to customers for the North America growing season . Revenue recognized during the three months ended March 31, 2018 from amounts included in deferred revenue at the beginning of the period was $563 million . Disaggregation of Revenue Effective with the Merger, DuPont’s business activities are components of its parent company’s business operations. DuPont’s business activities, including the assessment of performance and allocation of resources, are reviewed and managed by DowDuPont. Information used by the chief operating decision maker of DuPont relates to the company in its entirety. Accordingly, there are no separate reportable business segments for DuPont under ASC Topic 280 “Segment Reporting” and DuPont's business results are reported in this Form 10-Q as a single operating segment. The company has one reportable segment with the following principal product lines: agriculture, packaging and specialty plastics, electronics and imaging, nutrition and health, industrial biosciences, transportation and advanced polymers and safety and construction. The company believes disaggregation of revenue by principal product line best depicts the nature, amount, timing, and uncertainty of its revenue and cash flows.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	RESTRUCTURING AND ASSET RELATED CHARGES - NET DowDuPont Cost Synergy Program In September and November 2017, DowDuPont and the company approved post-merger restructuring actions under the DowDuPont Cost Synergy Program (the “Synergy Program”), adopted by the DowDuPont Board of Directors. The plan is designed to integrate and optimize the organization following the Merger and in preparation for the Intended Business Separations. Based on all actions approved to date under the Synergy Program, DuPont expects to record total pre-tax restructuring charges of $430 million to $600 million , comprised of approximately $320 million to $360 million of severance and related benefits costs; $110 million to $140 million of costs related to contract terminations; and up to $100 million of asset related charges. The Synergy Program includes certain asset actions that are reflected in the preliminary fair value measurement of DuPont’s assets as of the merger date. Current estimated total pre-tax restructuring charges could be impacted by future adjustments to the preliminary fair value of DuPont’s assets. As a result of these actions, the company recorded pre-tax restructuring charges of $187 million for the period September 1 through December 31, 2017, consisting of severance and related benefit costs of $153 million , contract termination costs of $31 million and asset related charges of $3 million . For the three months ended March 31, 2018, DuPont recorded a pre-tax charge of $97 million , consisting of severance and related benefit costs of $68 million and contract termination costs of $29 million . The charge for the three months ended March 31, 2018 was recognized in restructuring and asset related charges - net in the company's interim Consolidated Statements of Operations. Substantially all of the remaining restructuring charges are expected to be incurred in 2018 and the related actions, including employee separations, associated with this plan are expected to be substantially complete by the end of 2019. DuPont account balances and activity for the Synergy Program in the Successor period are summarized below: (In millions) Severance and Related Benefit Costs Contract Termination Charges Total Balance as of December 31, 2017 $ 133 $ 28 $ 161 Charges to loss from continuing operations for the three months ended March 31, 2018 68 29 97 Payments (31 ) (16 ) (47 ) Net translation adjustment 1 — 1 Balance as of March 31, 2018 $ 171 $ 41 $ 212 2017 Restructuring Program At March 31, 2018, total liabilities related to the program were $15 million . The actions associated with this plan were substantially complete in 2017. A complete discussion of restructuring initiatives is included in the company's 2017 Annual Report in Note 5, "Restructuring and Asset Related Charges - Net." During the three months ended March 31, 2017, a net charge of $152 million was recorded, consisting of $119 million of asset related charges and $33 million of severance and related benefit costs. The asset related charges mainly consist of accelerated depreciation associated with the closure of the safety and construction product line at the Cooper River manufacturing site located near Charleston, South Carolina.

Miscellaneous income and expenses - net, includes interest items (Predecessor period only), gains related to litigation settlements, and other items. The following table summarizes the impacts of the company's foreign currency hedging program on the company's results of operations. The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The hedging program gains (losses) are largely taxable (tax deductible) in the United States (U.S.), whereas the offsetting exchange gains (losses) on the remeasurement of the net monetary asset positions are often not taxable (tax deductible) in their local jurisdictions. The net pre-tax exchange gains (losses) are recorded in sundry income - net and the related tax impact is recorded in provision for income taxes on continuing operations in the interim Consolidated Statements of Operations.

Income Tax Disclosure [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 (“transition tax”) on earnings of foreign subsidiaries that were previously tax deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves towards a territorial system. At March 31, 2018, the company had not completed its accounting for the tax effects of The Act; however, as described below, the company has made reasonable estimates of the effects on its existing deferred tax balances and the one-time transition tax. In accordance with Staff Accounting Bulletin 118 ("SAB 118"), during the measurement period, income tax effects of the Act may be refined upon obtaining, preparing, or analyzing additional information, 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 by U.S. regulatory and standard-setting bodies. • As a result of The Act, the company 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 company is still analyzing certain aspects of The Act and refining its calculations. In the first quarter 2018, a $48 million charge was recorded to provision for income taxes on continuing operations in the company's interim Consolidated Statements of Operations to adjust the provisional amount related to the remeasurement of the company's deferred tax balance, resulting in a benefit of $(2,668) million since the enactment of The Act. • 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. The company 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 Federal income tax return is filed. The company has not recorded a change to the $715 million provisional charge recorded during the fourth quarter 2017 with respect to the one-time transition tax. • In the first quarter 2018, the company recognized a charge of $16 million to provision for income taxes on continuing operations in the company's interim Consolidated Statements of Operations as a result of an indirect impact of the Act related to certain inventory. • 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"). The company is evaluating the 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. DuPont and its subsidiaries are included in DowDuPont's consolidated federal income tax group and consolidated tax return. Generally, the consolidated tax liability of the DowDuPont U.S. tax group for each year will be apportioned among the members of the consolidated group based on each member’s separate taxable income. DuPont and Dow intend that to the extent Federal and/or State corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or tax matters agreement. Each year the company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the company. As a result, there is an uncertainty in income taxes recognized in the company's financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. The ultimate resolution of such uncertainties is not expected to have a material impact on the company's results of operations. During the three months ended March 31, 2017, the company recognized a tax benefit of $57 million , as well as a $50 million pre-tax benefit on associated accrued interest reversals, related to a reduction in the company's unrecognized tax benefits due to the closure of various tax statutes of limitations. Income from continuing operations during the three months ended March 31, 2017 includes a tax benefit of $53 million and a pre-tax benefit of $47 million for accrued interest reversals (recorded in sundry income - net). Loss from discontinued operations during the three months ended March 31, 2017 includes a tax benefit of $4 million and a pre-tax benefit of $3 million for the accrued interest reversal.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	SHORT-TERM BORROWINGS, LONG-TERM DEBT AND AVAILABLE CREDIT FACILITIES Repurchase Facility In February 2018, the company entered into a new committed receivable repurchase facility of up to $1,300 million (the "2018 Repurchase Facility") which expires in December 2018. From time to time, the company and the banks modify the monthly commitment amounts to better align with working capital requirements. Under the 2018 Repurchase Facility, DuPont may sell a portfolio of available and eligible outstanding agriculture product line customer notes receivables to participating institutions and simultaneously agree to repurchase at a future date. The 2018 Repurchase Facility is considered a secured borrowing with the customer notes receivables inclusive of those that are sold and repurchased, equal to 105 percent of the outstanding amounts borrowed utilized as collateral. Borrowings under the 2018 Repurchase Facility will have an interest rate of LIBOR + 0.75 percent . As of March 31, 2018 , $42 million of notes receivable, recorded in accounts and notes receivable - net, were pledged as collateral against outstanding borrowings under the Repurchase Facility of $40 million , recorded in short-term borrowings and capital lease obligations on the interim Condensed Consolidated Balance Sheet. Term Loan and Revolving Credit Facilities In March 2016, the company entered into a credit agreement that provides for a three -year, senior unsecured term loan facility in the aggregate principal amount of $4,500 million (as may be amended, from time to time, the "Term Loan Facility") under which DuPont may make up to seven term loan borrowings and amounts repaid or prepaid are not available for subsequent borrowings. The proceeds from the borrowings under the Term Loan Facility will be used for the company's general corporate purposes including debt repayment, working capital and funding a portion of DowDuPont's costs and expenses. The Term Loan Facility was amended in 2018 to extend the maturity date to June 2020, at which time all outstanding borrowings, including accrued but unpaid interest, become immediately due and payable, and to extend the date on which the commitment to lend terminates to June 2019. At March 31, 2018 , the company had made three term loan borrowings in an aggregate principal amount of $1,500 million and had unused commitments of $3,000 million under the Term Loan Facility. In addition, in 2018 the company amended its $3,000 million revolving credit facility to extend the maturity date to June 2020.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENT LIABILITIES Guarantees Indemnifications In connection with acquisitions and divestitures as of March 31, 2018 , the company has indemnified respective parties against certain liabilities that may arise in connection with these transactions and business activities prior to the completion of the transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. In addition, the company indemnifies its duly elected or appointed directors and officers to the fullest extent permitted by Delaware law, against liabilities incurred as a result of their activities for the company, such as adverse judgments relating to litigation matters. If the indemnified party were to incur a liability or have a liability increase as a result of a successful claim, pursuant to the terms of the indemnification, the company would be required to reimburse the indemnified party. The maximum amount of potential future payments is generally unlimited. Obligations for Equity Affiliates & Others The company has directly guaranteed various debt obligations under agreements with third parties related to equity affiliates, customers and suppliers. At March 31, 2018 and December 31, 2017 , the company had directly guaranteed $284 million and $297 million , respectively, of such obligations. These amounts represent the maximum potential amount of future (undiscounted) payments that the company could be required to make under the guarantees. The company would be required to perform on these guarantees in the event of default by the guaranteed party. The company assesses the payment/performance risk by assigning default rates based on the duration of the guarantees. These default rates are assigned based on the external credit rating of the counterparty or through internal credit analysis and historical default history for counterparties that do not have published credit ratings. For counterparties without an external rating or available credit history, a cumulative average default rate is used. In certain cases, the company has recourse to assets held as collateral, as well as personal guarantees from customers and suppliers. Assuming liquidation, these assets are estimated to cover approximately 20 percent of the $80 million of guaranteed obligations of customers and suppliers. Set forth below are the company's guaranteed obligations at March 31, 2018 . The following tables provide a summary of the final expiration year and maximum future payments for each type of guarantee: Guarantees at March 31, 2018 (Successor) Final Expiration Year Maximum Future Payments (In millions) Obligations for customers and suppliers 1 : Bank borrowings 2022 $ 80 Obligations for non-consolidated affiliates 2 : Bank borrowings 2018 168 Residual value guarantees 3 2029 36 Total guarantees $ 284 1. Existing guarantees for customers and suppliers, as part of contractual agreements. 2. Existing guarantees for non-consolidated affiliates' liquidity needs in normal operations. 3. The company provides guarantees related to leased assets specifying the residual value that will be available to the lessor at lease termination through sale of the assets to the lessee or third parties. Litigation The company is subject to various legal proceedings arising out of the normal course of its current and former business operations, including product liability, intellectual property, commercial, environmental and antitrust lawsuits. It is not possible to predict the outcome of these various proceedings. Although considerable uncertainty exists, management does not anticipate that the ultimate disposition of these matters will have a material adverse effect on the company's results of operations, consolidated financial position or liquidity. However, the ultimate liabilities could be material to results of operations in the period recognized. PFOA Matters DuPont used PFOA (collectively, perfluorooctanoic acids and its salts, including the ammonium salt), as a processing aid to manufacture some fluoropolymer resins at various sites around the world including its Washington Works' plant in West Virginia. Pursuant to the Separation Agreement discussed in Note 4 , the company is indemnified by Chemours for the PFOA matters discussed below and has recorded a total indemnification asset of $14 million . U.S. Environmental Protection Agency (“EPA") and New Jersey Department of Environmental Protection (“NJDEP”) DuPont is obligated under agreements with the EPA, including a 2009 consent decree to which Chemours was added in 2017, and has made voluntary commitments to the NJDEP. These obligations and voluntary commitments include surveying, sampling and testing drinking water in and around certain company sites and offering treatment or an alternative supply of drinking water if tests indicate the presence of PFOA in drinking water at or greater than the national health advisory level established from time to time by the EPA. At March 31, 2018, the company had an accrual of $14 million related to these obligations and voluntary commitments. The company recorded an indemnification asset corresponding to the accrual balance at March 31, 2018. Leach v. DuPont In August 2001, a class action, captioned Leach v. DuPont, was filed in West Virginia state court alleging that residents living near the Washington Works facility had suffered, or may suffer, deleterious health effects from exposure to PFOA in drinking water. A settlement was reached in 2004 that binds approximately 80,000 residents, (the "Leach Settlement"). In addition to paying $23 million to plaintiff’s attorneys for fees and expenses and $70 million to fund a community health project, the company is obligated to fund up to $235 million for a medical monitoring program for eligible class members and to pay administrative costs and fees associated with the program. Since the establishment in 2012 of an escrow account to fund medical monitoring as required by the settlement agreement, approximately $2 million has been contributed to the account and approximately $1 million has been disbursed from the account. The company also must continue to provide water treatment designed to reduce the level of PFOA in water to six area water districts, including the Little Hocking Water Association, and private well users. While it is probable that the company will incur liabilities related to funding the medical monitoring program and providing water treatment, the company does not expect any such liabilities to be material. Under the Leach Settlement, the company funded a series of health studies which were completed in October 2012 by an independent science panel of experts (the "C8 Science Panel"). The C8 Science Panel found probable links, as defined in the Leach Settlement, between exposure to PFOA and pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol. Leach class members may pursue personal injury claims against DuPont only for the six human diseases for which the C8 Science Panel determined a probable link exists. Following the Leach Settlement, approximately 3,550 lawsuits alleging personal injury claims were filed in various federal and state courts in Ohio and West Virginia. These lawsuits are consolidated in multi-district litigation ("MDL") in the U.S. District Court for the Southern District of Ohio. MDL Settlement In the first quarter of 2017, the MDL was settled for $670.7 million in cash (the "MDL Settlement"), half of which was paid by Chemours and half paid by DuPont. The portion paid by DuPont was recorded, for the three months ended March 31, 2017, within loss from discontinued operations after income taxes in the interim Consolidated Statements of Operations. In 2017, all payments under the settlement agreement were made by both companies. DuPont’s payment was not subject to indemnification or reimbursement by Chemours. In exchange for that payment, DuPont and Chemours are receiving releases of all claims by the settling plaintiffs. The MDL Settlement was entered into solely by way of compromise and settlement and is not in any way an admission of liability or fault by DuPont or Chemours. All of the MDL plaintiffs participated and resolved their claims within the MDL Settlement. Post MDL Settlement PFOA Personal Injury Claims The MDL Settlement did not resolve claims of plaintiffs who did not have claims in the MDL or whose claims are based on diseases first diagnosed after February 11, 2017. At March 31, 2018, 34 lawsuits alleging personal injury, including kidney and testicular cancer, from exposure to PFOA in drinking water had been filed against the company in West Virginia and Ohio. In addition, three lawsuits are pending in federal court in New York on behalf of five individuals who are residents of Hoosick Falls, New York. The plaintiffs claim personal injuries, including kidney cancer, thyroid disease and ulcerative colitis, from alleged exposure to PFOA discharged into the air and water from nearby manufacturing facilities owned and operated by defendant third parties. Plaintiffs claim that PFOA used at the facilities was purchased from or manufactured by the company and co-defendant, 3M Company. Water Utility and Related Actions Actions filed by local water utilities pending in Alabama and New Jersey state court allege contamination from PFOA, and in the case of the Alabama action, perfluorinated chemicals and compounds, including PFOA, (“PFCs”) used in co-defendant manufacturers’ operations. In February 2018, the State of Ohio filed suit in Ohio state court alleging natural resource damages from historical PFOA emissions from the Washington Works site. The plaintiffs in these suits seek monetary damages, remediation and other costs / damages. While it is reasonably possible that the company could incur liabilities related to the post MDL Settlement PFOA personal injury claims and the water utility and related actions described above, any such liabilities are not expected to be material. Chemours is defending and indemnifying the company in these matters in accordance with the amendment to the Separation Agreement discussed below. Amendment to Separation Agreement Concurrent with the MDL Settlement, DuPont and Chemours amended the Separation Agreement to provide for a limited sharing of potential future PFOA liabilities (i.e., indemnifiable losses, as defined in the Separation Agreement) for a period of five years beginning July 6, 2017. During that five -year period, Chemours will annually pay future PFOA liabilities up to $25 million and, if such amount is exceeded, DuPont would pay any excess amount up to the next $25 million (which payment will not be subject to indemnification by Chemours), with Chemours annually bearing any further excess liabilities. After the five -year period, this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Separation Agreement will continue unchanged. There have been no charges incurred by DuPont under this arrangement through March 31, 2018. Chemours has also agreed that it will not contest its liability to DuPont under the Separation Agreement for PFOA liabilities on the basis of ostensible defenses generally applicable to the indemnification provisions under the Separation Agreement, including defenses relating to punitive damages, fines or penalties or attorneys’ fees, and waives any such defenses with respect to PFOA liabilities. Chemours has, however, retained defenses as to whether any particular PFOA claim is within the scope of the indemnification provisions of the Separation Agreement. It is possible that new lawsuits could be filed against DuPont related to PFOA that may not be within the scope of the MDL Settlement. Any such new litigation would be subject to indemnification by Chemours under the Separation Agreement, as amended. Fayetteville Works Facility, North Carolina Prior to the separation of Chemours, the company introduced GenX as a polymerization processing aid and a replacement for PFOA at the Fayetteville Works facility. The facility is now owned and operated by Chemours which continues to manufacture and use GenX. Chemours is responding to ongoing inquiries and investigations from federal, state and local investigators, regulators and other governmental authorities as well as inquiries from the media and local community stakeholders. These inquiries and investigations involve the discharge of GenX and certain similar compounds from the Chemours’ facility at Fayetteville Works into the Cape Fear River in Bladen County, North Carolina. In August 2017, the U.S. Attorney’s Office for the Eastern District of North Carolina served the company with a grand jury subpoena for testimony and the production of documents related to alleged discharges of GenX from the Fayetteville Works facility into the Cape Fear River. In the fourth quarter of 2017, DuPont was served with additional subpoenas relating to the same issue. It is possible that these ongoing inquiries and investigations, including the grand jury subpoena, could result in penalties or sanctions, or that additional litigation will be instituted against Chemours and/or the company. At March 31, 2018, several actions, filed on behalf of putative classes of property owners and residents in areas near or who draw drinking water from the Cape Fear River, are pending in federal court against Chemours and the company. DowDuPont has been dismissed without prejudice from all such actions in which it was named. These actions relate to the alleged discharge of certain PFCs into the river from the operations and wastewater treatment at the Fayetteville Works facility. The actions, filed in the fourth quarter of 2017 and consolidated into a single purported class action, seek various relief including medical monitoring, property damages and injunctive relief. Separate actions filed by the various North Carolina water authorities including Cape Fear Public Utility Authority and Brunswick County, North Carolina, have been consolidated into a single purported class action seeking actual and punitive damages as well as injunctive relief. In the first quarter of 2018, approximately 70 plaintiffs, who own property near the Fayetteville Works facility, filed an action seeking damages for nuisance allegedly caused by releases of certain PFCs from the site. Management believes the probability of loss with respect to these actions is remote. The company has an indemnification claim against Chemours with respect to current and future inquiries and claims, including lawsuits, related to the foregoing. At March 31, 2018, Chemours is defending and indemnifying the company in the pending civil actions. Environmental 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 March 31, 2018 , the company had accrued obligations of $430 million for probable environmental remediation and restoration costs, including $61 million for the remediation of Superfund sites. These obligations are included in accrued and other current liabilities and other noncurrent obligations in the interim Condensed Consolidated Balance Sheets. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the company has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to $885 million above the amount accrued at March 31, 2018 . Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the company’s results of operations, financial condition and cash flows. It is the opinion of the company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the company’s results of operations, financial condition or cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. Pursuant to the Separation Agreement, the company is indemnified by Chemours for certain environmental matters, included in the liability of $430 million , that have an estimated liability of $242 million as of March 31, 2018 , and a potential exposure that ranges up to approximately $430 million above the amount accrued. As such, the company has recorded an indemnification asset of $242 million corresponding to the company’s accrual balance related to these matters at March 31, 2018 , including $42 million related to the Superfund sites.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments Disclosure [Text Block]	FINANCIAL INSTRUMENTS At March 31, 2018 , the company had $3,838 million ( $5,205 million at December 31, 2017 ) of held-to-maturity securities (primarily time deposits and money market funds) classified as cash equivalents, as these securities had maturities of three months or less at the time of purchase; and $246 million ( $952 million at December 31, 2017 ) of held-to-maturity securities (primarily time deposits) classified as marketable securities as these securities had maturities of more than three months to less than one year at the time of purchase. The company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. These securities are included in cash and cash equivalents, marketable securities, and other current assets in the consolidated balance sheets. Available-for-sale securities are reported at estimated fair value with unrealized gains and losses reported as a component of accumulated other comprehensive loss. There were no sales of available-for-sale securities for the three months ended March 31, 2018 and 2017, respectively. Derivative Instruments Objectives and Strategies for Holding Derivative Instruments In the ordinary course of business, the company enters into contractual arrangements (derivatives) to reduce its exposure to foreign currency, interest rate and commodity price risks. The company has established a variety of derivative programs to be utilized for financial risk management. These programs reflect varying levels of exposure coverage and time horizons based on an assessment of risk. Derivative programs have procedures and controls and are approved by the Corporate Financial Risk Management Committee, consistent with the company's financial risk management policies and guidelines. Derivative instruments used are forwards, options, futures and swaps. The company has not designated any nonderivatives as hedging instruments. The company's financial risk management procedures also address counterparty credit approval, limits and routine exposure monitoring and reporting. The counterparties to these contractual arrangements are major financial institutions and major commodity exchanges. The company is exposed to credit loss in the event of nonperformance by these counterparties. The company utilizes collateral support annex agreements with certain counterparties to limit its exposure to credit losses. The company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Market and counterparty credit risks associated with these instruments are regularly reported to management. The notional amounts of the company's derivative instruments were as follows: Notional Amounts Successor (In millions) March 31, 2018 December 31, 2017 Derivatives designated as hedging instruments: Commodity contracts $ 264 $ 587 Derivatives not designated as hedging instruments: Foreign currency contracts 9,959 10,454 Commodity contracts 34 6 Foreign Currency Risk The company's objective in managing exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency rate changes. Accordingly, the company enters into various contracts that change in value as foreign exchange rates change to protect the value of its existing foreign currency-denominated assets, liabilities, commitments and cash flows. The company routinely uses forward exchange contracts to offset its net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of its operations. The primary business objective of this hedging program is to maintain an approximately balanced position in foreign currencies so that exchange gains and losses resulting from exchange rate changes, net of related tax effects, are minimized. The company also uses foreign currency exchange contracts to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues. The objective of the hedge program is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates. Commodity Price Risk Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as corn, soybeans, soybean oil and soybean meal. The company enters into over-the-counter and exchange-traded derivative commodity instruments to hedge the commodity price risk associated with agricultural commodity exposures. Derivatives Designated as Cash Flow Hedges Foreign Currency Contracts The company uses foreign currency exchange instruments such as forwards and options to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues. In addition, the company occasionally uses forward exchange contracts to offset a portion of the company’s exposure to certain foreign currency-denominated transactions such as capital expenditures. Commodity Contracts The company enters into over-the-counter and exchange-traded derivative commodity instruments, including options, futures and swaps, to hedge the commodity price risk associated with agriculture commodity exposures. While each risk management program has a different time maturity period, most programs currently do not extend beyond the next two -year period. Cash flow hedge results are reclassified into earnings during the same period in which the related exposure impacts earnings. Reclassifications are made sooner if it appears that a forecasted transaction is not probable of occurring. The following table summarizes the after-tax effect of cash flow hedges on accumulated other comprehensive loss: Successor Predecessor (In millions) Three Months Ended March 31, 2018 Three Months Ended March 31, 2017 Beginning balance $ (2 ) $ 7 Additions and revaluations of derivatives designated as cash flow hedges 12 2 Clearance of hedge results to earnings (1 ) (5 ) Ending balance $ 9 $ 4 At March 31, 2018 , an after-tax net gain of $4 million is expected to be reclassified from accumulated other comprehensive loss into earnings over the next twelve months. Derivatives not Designated in Hedging Relationships Foreign Currency Contracts The company routinely uses forward exchange contracts to reduce its net exposure, by currency, related to foreign currency-denominated monetary assets and liabilities of its operations so that exchange gains and losses resulting from exchange rate changes are minimized. The netting of such exposures precludes the use of hedge accounting; however, the required revaluation of the forward contracts and the associated foreign currency-denominated monetary assets and liabilities intends to achieve a minimal earnings impact, after taxes. The company also uses foreign currency exchange contracts to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on the contracts offset changes in the USD value of the related foreign currency-denominated revenues. Commodity Contracts The company utilizes options, futures and swaps that are not designated as hedging instruments to reduce exposure to commodity price fluctuations on purchases of inventory such as corn, soybeans, soybean oil and soybean meal. Fair Value of Derivative Instruments Asset and liability derivatives subject to an enforceable master netting arrangement with the same counterparty are presented on a net basis in the interim Condensed Consolidated Balance Sheets. The presentation of the company's derivative assets and liabilities is as follows: Successor March 31, 2018 (In millions) Balance Sheet Location Gross Counterparty and Cash Collateral Netting 1 Net Amounts Included in the Condensed Consolidated Balance Sheet Asset derivatives: Derivatives not designated as hedging instruments: Foreign currency contracts Other current assets $ 33 $ (24 ) $ 9 Total asset derivatives $ 33 $ (24 ) $ 9 Liability derivatives: Derivatives not designated as hedging instruments: Foreign currency contracts Accrued and other current liabilities $ 70 $ (20 ) $ 50 Total liability derivatives $ 70 $ (20 ) $ 50 1.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Interim Financial Statements The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the company’s Annual Report on Form 10-K for the year ended December 31, 2017, collectively referred to as the “2017 Annual Report”. The interim Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained.
Pushdown Accounting [Policy Text Block]	Principles of Consolidation and Basis of Presentation DowDuPont Inc. ("DowDuPont") was formed on December 9, 2015 to effect an all-stock, merger of equals strategic combination between The Dow Chemical Company ("Dow") and DuPont (the "Merger Transaction"). On August 31, 2017 at 11:59 pm ET, (the "Merger Effectiveness Time") pursuant to the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), Dow and DuPont each merged with wholly owned subsidiaries of DowDuPont ("Mergers") and, as a result of the Mergers, Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the Merger Agreement. DowDuPont intends to pursue, subject to certain customary conditions, including, among others, the effectiveness of registration statements filed with the Securities and Exchange Commission and approval by the Board of Directors of DowDuPont, the separation of the combined company's agriculture business, specialty products business and materials science business through a series of tax-efficient transactions (collectively, the "Intended Business Separations"). For purposes of DowDuPont's financial statement presentation, Dow was determined to be the accounting acquirer in the Merger and DuPont's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. In connection with the Merger and the related accounting determination, DuPont has elected to apply push-down accounting and reflect in its financial statements the fair value of its assets and liabilities. DuPont's interim Consolidated Financial Statements for periods following the close of the Merger are labeled “Successor” and reflect DowDuPont’s basis in the fair values of the assets and liabilities of DuPont. All periods prior to the closing of the Merger reflect the historical accounting basis in DuPont's assets and liabilities and are labeled “Predecessor.” The interim Consolidated Financial Statements and footnotes include a black line division between the columns titled "Predecessor" and "Successor" to signify that the amounts shown for the periods prior to and following the Merger are not comparable. See Note 3 for additional information on the Merger. Transactions between DuPont and DowDuPont, Dow and their affiliates and other associated companies are reflected in the Successor consolidated financial statements and disclosed as related party transactions when material. Related party transactions with Dow and DowDuPont are included in Note 7 .
Discontinued Operations, Policy [Policy Text Block]	As a condition of the regulatory approval for the Merger Transaction, the company was required to divest certain assets related to its crop protection business and research and development ("R&D") organization, specifically the company’s Cereal Broadleaf Herbicides and Chewing Insecticides portfolios, including Rynaxypyr ® , Cyazypyr ® and Indoxacarb as well as the crop protection R&D pipeline and organization, excluding seed treatment, nematicides, and late-stage R&D programs. On March 31, 2017, the company entered into a definitive agreement (the "FMC Transaction Agreement") with FMC Corporation ("FMC"). Under the FMC Transaction Agreement, FMC would acquire the crop protection business and R&D assets that DuPont was required to divest in order to obtain European Commission ("EC") approval of the Merger Transaction as described above, (the "Divested Ag Business") and DuPont agreed to acquire certain assets relating to FMC’s Health and Nutrition segment, excluding its Omega-3 products (the "H&N Business") (collectively, the "FMC Transactions"). On November 1, 2017, the company completed the FMC Transactions through the disposition of the Divested Ag Business and the acquisition of the H&N Business. The sale of the Divested Ag Business meets the criteria for discontinued operations and as such, results of operations are presented as discontinued operations and have been excluded from continuing operations for all periods presented. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The comprehensive income and cash flows related to the Divested Ag Business have not been segregated and are included in the interim Consolidated Statements of Comprehensive Income and interim Condensed Consolidated Statements of Cash Flows, respectively, for all periods presented. Amounts related to the Divested Ag Business are consistently included or excluded from the Notes to the interim Consolidated Financial Statements based on the respective financial statement line item. See Note 4 for additional information.
Reclassification, Policy [Policy Text Block]	Changes in Accounting and Reporting Within the Successor period, DuPont made the following changes in accounting and reporting to harmonize its accounting and reporting with DowDuPont. Within the Successor period of the interim Consolidated Statements of Operations: • Included royalty income within net sales. In the Predecessor periods, royalty income is included within sundry income - net. • Eliminated the other operating charges line item. In the Successor period, a majority of these costs are included within cost of goods sold. These costs are also included in selling, general and administrative expenses and amortization of intangibles in the Successor period. • Presented amortization of intangibles as a separate line item. In the Predecessor periods, amortization is included within selling, general and administrative expenses, other operating charges, and research and development expenses. • Presented integration and separation costs as a separate line item. In the Predecessor periods, these costs are included within selling, general and administrative expenses. • Included interest accrued related to unrecognized tax benefits within the provision for income taxes on continuing operations. In the Predecessor period, interest accrued related to unrecognized tax benefits is included within sundry income - net. Within the Successor period of the interim Condensed Consolidated Statements of Cash Flows: • Included foreign currency exchange contract settlements within cash flows from operating activities, regardless of hedge accounting qualification. In the Predecessor period, DuPont reflected non-qualified hedge programs, specifically forward contracts, options and cash collateral activity, within cash flows from investing activities. In the Predecessor period, DuPont reflected cash flows from qualified hedge programs within the line item to which the program related (i.e., revenue hedge cash flows presented within changes from accounts receivable). Certain reclassifications of prior year's data have been made to conform to current year's presentation. As described in Note 2 , effective January 1, 2018, the company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. In conjunction with the adoption of this ASU, the company retrospectively reclassified the non-service components of net periodic benefit cost in the interim Consolidated Statements of Operations, as described in Note 2 .
Revenue Recognition, Policy [Policy Text Block]	Revenue The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To determine revenue recognition for the arrangements that the company determines are within the scope of Topic 606, the company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 5 for additional information on revenue recognition.

Accounting Policies [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which was further updated in March, April, May and December 2016, as well as September and November 2017. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The new standard resulted in additional disclosure requirements to describe the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The standard permits the use of either the retrospective or modified retrospective (cumulative-effect) transition method of adoption. The company adopted this standard in the first quarter of 2018 and applied the modified retrospective transition method to contracts not completed at the date of initial application. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting under Topic 605 (Revenue Recognition). The company recognized the cumulative effect of applying the new revenue standard as an adjustment to the opening balance of retained earnings in the beginning of 2018. See Note 5 for additional disclosures regarding the company's contracts with customers. In accordance with Topic 606, the disclosure of the impact of adoption to the company's interim Condensed Consolidated Balance Sheet was as follows: (In millions, except per share amounts) As Reported December 31, 2017 Effect of Adoption of ASU 2014-09 Updated January 1, 2018 Current assets Accounts and notes receivable - net $ 5,239 $ 65 $ 5,304 Inventories 8,633 (53 ) 8,580 Other current assets 981 115 1,096 Deferred income taxes $ 480 $ 1 $ 481 Liabilities and Equity Current liabilities Accounts payable $ 4,831 $ (3 ) $ 4,828 Accrued and other current liabilities 4,384 120 4,504 Deferred income tax liabilities $ 5,836 $ 3 $ 5,839 Retained earnings $ 175 $ 8 $ 183 The most significant changes as a result of adopting ASU No. 2014-09 relate to the reclassification of the company's return assets and refund liabilities in the agriculture product line on the interim Condensed Consolidated Balance Sheets. Under previous guidance, the company accrued the amount of expected product returns as a reduction of net sales and a reduction of accounts and notes receivable - net, and the value associated with the products expected to be recovered in inventory along with a corresponding reduction in cost of goods sold. Under Topic 606, the company now separately presents the amount of expected product returns as refund liabilities, included in accrued and other current liabilities, and the products expected to be recovered as return assets, included in other current assets in the consolidated balance sheets. The reclassification of return assets and refund liabilities was $61 million and $119 million , respectively, at January 1, 2018. The effect on the interim Consolidated Statements of Operations and the interim Condensed Consolidated Statement of Cash Flows was not material. The following table summarizes the effects of adopting the new accounting standard related to revenue recognition on the company's interim Condensed Consolidated Balance Sheet: March 31, 2018 (In millions, except per share amounts) As Reported Effect of Change Balance without Adoption of Topic 606 Current assets Accounts and notes receivable - net $ 7,147 $ (205 ) $ 6,942 Inventories 7,901 111 8,012 Other current assets 1,287 (168 ) 1,119 Deferred income taxes $ 330 $ (1 ) $ 329 Liabilities and Equity Current liabilities Accrued and other current liabilities $ 4,133 $ (258 ) $ 3,875 Deferred income tax liabilities $ 5,669 $ (2 ) $ 5,667 Accumulated deficit $ (881 ) $ (3 ) $ (884 ) In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The new guidance makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The new guidance requires adoption on a retrospective basis unless it is impracticable to apply, in which case the company would be required to apply the amendments prospectively as of the earliest date practicable. The company adopted this standard on January 1, 2018 and there was no material impact. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than when the asset is sold to an outside party. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The new guidance requires adoption on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The company adopted this standard on January 1, 2018 and there was no adjustment to retained earnings. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash (a consensus of the FASB Emerging Issues Task Force), which clarifies how entities should present restricted cash and restricted cash equivalents in the statement of cash flows, and, as a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. An entity with a material balance of restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The company adopted this standard on January 1, 2018. See the interim Condensed Consolidated Statement of Cash Flows for the new presentation of restricted cash as well as Note 8 for a reconciliation of cash, cash equivalents and restricted cash (included in other current assets) presented on the interim Condensed Consolidated Balance Sheets to the total cash, cash equivalents and restricted cash presented in the interim Condensed Consolidated Statements of Cash Flows. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business. The new guidance narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities (collectively, the "set") is not a business. To be considered a business, the set would need to include an input and a substantive process that together significantly contribute to the ability to create outputs, as defined by the ASU. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, and should be applied prospectively. Early adoption is permitted. The company adopted this standard on January 1, 2018 and will apply it prospectively to all applicable transactions after the adoption date. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance requires registrants to present the service cost component of net periodic benefit cost in the same income statement line item or items as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Registrants will present the other components of net periodic benefit cost separately from the service cost component; and, the line item or items used in the income statement to present the other components of net periodic benefit cost must be disclosed. The new standard must be adopted retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement, and prospectively for the capitalization of the service cost component of net periodic benefit cost in assets. The company adopted this guidance on January 1, 2018, and will record the other components of net periodic benefit cost in sundry income - net. The following table summarizes the reclassification of those costs from cost of goods sold, research and development expense, and selling, general and administrative expenses to sundry income - net in the interim Consolidated Statements of Operations: Summary of Changes to the interim Consolidated Statement of Operations For the Three Months Ended March 31, 2017 (Predecessor) (in millions) As reported 1 Effect of Change Updated Cost of goods sold $ 4,209 $ (57 ) $ 4,152 Research and development expense $ 384 $ (16 ) $ 368 Selling, general and administrative expenses $ 1,221 $ (31 ) $ 1,190 Sundry income - net $ 306 $ (104 ) $ 202 1. Includes adjustments for discontinued operations. Accounting Guidance Issued But Not Adopted as of March 31, 2018 In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The new guidance expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged items in the financial statements. For cash flow and net investment hedges existing as of the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year in which an entity adopts. Presentation and disclosure guidance is required to be adopted prospectively. The new standard is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted in any interim period. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption. The company will early adopt the new guidance in the second quarter of 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under the new guidance will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new leasing standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The company is currently evaluating the impact of adopting this guidance on the Consolidated Financial Statements and related disclosures. The company is the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases. A complete discussion of these leases is included in the company's 2017 Annual Report in Note 14, "Commitments and Contingent Liabilities."

Revenue from Contract with Customer [Abstract]
Revenue Recognition, Sales of Goods	Products Substantially all of DuPont's revenue is derived from product sales. Product sales consist of sales of DuPont's products to supply manufacturers, distributors, and farmers. DuPont considers purchase orders, which in some cases are governed by master supply agreements, to be a contract with a customer. Contracts with customers are considered to be short-term when the time between order confirmation and satisfaction of the performance obligations is equal to or less than one year. Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms for contracts related to product lines other than agriculture generally average 30 to 60 days after invoicing, depending on business and geography. Payment terms for agriculture product line contracts are generally less than one year from invoicing. The company elected the practical expedient and will not adjust the promised amount of consideration for the effects of a significant financing component when DuPont expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. The company has elected to recognize shipping and handling activities when control has transferred to the customer as an expense in cost of goods sold. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, DuPont elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less. The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates for variable consideration are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, DuPont allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances.
Revenue Recognition, Licenses of Intellectual Property	Licenses of Intellectual Property DuPont enters into licensing arrangements with customers under which it licenses its intellectual property, such as patents and trademarks. Revenue from the majority of intellectual property licenses is derived from sales-based royalties. The company estimates the expected amount of sales-based royalties based on historical sales by customer. Revenue for licensing agreements that contain sales-based royalties is recognized at the later of (i) when the subsequent sale occurs or (ii) when the performance obligation to which some or all of the royalty has been allocated is satisfied.
