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, 2018, collectively referred to as the “2018 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 ("Historical Dow") and Historical 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"), Historical Dow and Historical DuPont each merged with wholly owned subsidiaries of DowDuPont ("Mergers") and, as a result of the Mergers, Historical Dow and Historical 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 U.S. Securities and Exchange Commission ("SEC") 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" and the transactions to accomplish the Intended Business Separations, the "separations"). On February 26, 2018, DowDuPont announced the corporate brand names that each company plans to assume once the Intended Business Separations occur. Materials science is called Dow, agriculture will be called Corteva TM Agriscience, and specialty products will be called DuPont. Effective as of 5:00 pm ET on April 1, 2019, DowDuPont completed the previously announced separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock, par value $0.01 per share (the “Dow Common Stock”), to holders of DowDuPont's common stock, par value $0.01 per share (the “DowDuPont Common Stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”). DowDuPont expects to complete the previously announced intended separation of its agriculture business into a separate and independent public company on June 1, 2019 by way of a distribution of Corteva, Inc., a Delaware corporation and wholly-owned subsidiary of DowDuPont (“Corteva”), through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock, par value $0.01 per share, to holders of DowDuPont Common Stock as of a record date to be set by DowDuPont’s Board of Directors (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”). Refer to Notes 3 and 18 for additional information. Transactions between Historical DuPont and DowDuPont, Historical Dow and their affiliates and other associated companies are reflected in the Consolidated Financial Statements and disclosed as related party transactions when material. Related party transactions with Historical Dow and DowDuPont are included in Note 6 . 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 Historical 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 Historical 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 the three months ended March 31, 2018. 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 the three months ended March 31, 2018. 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 3 for additional information. Significant Accounting Policies The company has updated its leasing policy since the issuance of its 2018 Annual Report as a result of the adoption of ASU No. 2016-02, Leases (Topic 842) in the first quarter 2019. See Notes 2 and 11 for additional information. See Note 1, "Summary of Significant Accounting Policies," in the 2018 Annual Report for more information on Historical DuPont's other significant accounting policies. Leases The company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and the company has the right to control the asset. Operating lease right-of-use ("ROU") assets are included in other assets on the company’s Consolidated Balance Sheets. Operating lease liabilities are included in accrued and other current liabilities and other noncurrent obligations on the company’s Consolidated Balance Sheets. Finance lease assets are included in property, plant and equipment on the company’s Consolidated Balance Sheets. Finance lease liabilities are included in short-term borrowings and finance lease obligations and long-term debt on the company’s Consolidated Balance Sheets. Operating lease ROU assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the company’s leases do not provide the lessor's implicit rate, the company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The company recognizes lease expense for these leases on a straight-line basis over the lease term. The company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. In the Consolidated Statements of Operations, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term.

Recent Accounting Guidance

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on their balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from previous U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance issued in 2014 (Topic 606). The company adopted this standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 (Leases). In addition, the company has elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, does not require reassessment of prior conclusions related to contracts containing a lease, lease classification, and initial direct lease costs. As an accounting policy election, the company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and will account for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the company’s interim Condensed Consolidated Balance Sheet: (In millions) As Reported December 31, 2018 Effect of Adoption of ASU 2016-02 Updated January 1, 2019 Assets Property, plant and equipment - net of accumulated depreciation $ 12,186 $ 9 $ 12,195 Other assets $ 1,810 $ 758 $ 2,568 Liabilities and Equity Current liabilities Short-term borrowings and finance lease obligations $ 2,160 $ 1 $ 2,161 Accrued and other current liabilities $ 4,233 $ 234 $ 4,467 Long-Term Debt $ 5,812 $ 8 $ 5,820 Other noncurrent obligations $ 1,620 $ 524 $ 2,144 The adoption of the new guidance did not have a material impact on the company's interim Consolidated Statement of Operations and had no impact on the interim Condensed Consolidated Statement of Cash Flows.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	DIVESTITURES AND OTHER TRANSACTIONS The Intended Business Separations As discussed in the company’s 2018 Annual Report and in Note 1 , DowDuPont announced its intent to pursue the separation of the combined company's agriculture business, specialty products business and materials science business through a series of tax-efficient transactions. Refer to Note 18 for additional information on the Intended Business Separations and the separations. Integration and Separation Costs Integration and separation costs have been and are expected to be significant. These costs 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 within the interim Consolidated Statements of Operations. Three Months Ended March 31, (In millions) 2019 2018 Integration and separation costs $ 405 $ 255 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 Historical DuPont was required to divest in order to obtain EC approval of the Merger Transaction and Historical DuPont acquired the H&N Business. See further discussion of the FMC Transactions in Note 1 . The sale of the Divested Ag Business met the criteria for discontinued operations and as such, earnings were included within loss 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). Performance Chemicals On July 1, 2015, Historical 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 "Chemours Separation"). In connection with the Chemours Separation, the company and The Chemours Company ("Chemours") entered into a Separation Agreement (as amended, the "Chemours Separation Agreement"). Pursuant to the Chemours Separation Agreement, as discussed below, Chemours indemnifies Historical 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, Historical DuPont and Chemours amended the Chemours 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, 2019, the indemnification assets are $84 million within accounts and notes receivable - net and $289 million within other assets along with the corresponding liabilities of $84 million within accrued and other current liabilities and $289 million within other noncurrent obligations in the interim Condensed Consolidated Balance Sheet. See Note 13 for further discussion of the amendment to the Chemours Separation Agreement and certain litigation and environmental matters indemnified by Chemours.

Revenue (Notes)

Revenue (Notes)	3 Months Ended
	Mar. 31, 2019
Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	REVENUE Revenue Recognition Products Substantially all of Historical DuPont's revenue is derived from product sales. Product sales consist of sales of Historical DuPont's products to supply manufacturers, distributors, and farmers. Historical 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. Licenses of Intellectual Property Historical 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. Historical 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, 2019 December 31, 2018 (In millions) Accounts and notes receivable - trade 1 $ 5,619 $ 4,130 Contract assets - current 2 $ 36 $ 48 Deferred revenue - current 3 $ 2,033 $ 1,927 Deferred revenue - noncurrent 4 $ 28 $ 30 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 change in deferred revenue from December 31, 2018 to March 31, 2019 was substantially due to the receipt of customer prepayments under agriculture product line contracts, partially offset by agriculture seed deliveries to customers for the North America growing season, which were delayed due to weather conditions. Revenue recognized during the three months ended March 31, 2019 from amounts included in deferred revenue - current at the beginning of the period was approximately $460 million . Disaggregation of Revenue Effective with the Merger, Historical DuPont’s business activities are components of DowDuPont’s business operations. Historical 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 Historical DuPont relates to the company in its entirety. Accordingly, there are no separate reportable business segments for Historical DuPont under ASC 280 “Segment Reporting” and Historical 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.

Includes non-service related components of net periodic benefit credits (costs) (interest cost, expected return on plan assets, and amortization of unrecognized loss). 3. Miscellaneous income and expenses - net, includes 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 (benefit from) 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 December 31, 2018, the company had completed its accounting for the tax effects of The Act. • 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 . In the first quarter of 2018, the company recorded a $48 million charge 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. • In the first quarter of 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. Historical 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. Historical DuPont and Historical 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 first and second quarters of 2019, in connection with the Intended Business Separations, the company has and expects to continue repatriating certain funds from its foreign subsidiaries that are not needed to finance local operations or separation activities. During the three months ended March 31, 2019, the company recorded tax expense of $13 million associated with these repatriation activities. Beyond these expected repatriations, the company is still asserting indefinite reinvestment related to certain investments in foreign subsidiaries. During the three months ended March 31, 2019, the company recorded a tax benefit of $102 million related to an internal legal entity restructuring associated with the Intended Business Separations.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	LEASES The company has operating and finance leases for real estate, airplanes, railcars, fleet, certain machinery and equipment, and information technology assets. The company’s leases have remaining lease terms of 1 year to 50 years . For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend the lease when it is reasonably certain that the company will exercise that option. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable lease payments are not presented as part of the initial ROU asset or lease liability. Certain of the company's leases include residual value guarantees. These residual value guarantees are based on a percentage of the lessor's asset acquisition price and the amount of such guarantee declines over the course of the lease term. The portion of residual value guarantees that are probable of payment are included in the related lease liability on the accompanying Consolidated Balance Sheet other than certain finance leases that include the maximum residual value guarantee amount in the measurement of the related liability given the election to use the package of practical expedients at the date of adoption. At March 31, 2019, the company has future maximum payments for residual value guarantees in operating leases of $46 million with final expirations through 2028. The company's lease agreements do not contain any material restrictive covenants.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	SHORT-TERM BORROWINGS, LONG-TERM DEBT AND AVAILABLE CREDIT FACILITIES Repurchase Facility In February 2019, the company entered into a new committed receivable repurchase facility of up to $1,300 million (the "2019 Repurchase Facility") which expires in December 2019. From time to time, the company and the banks modify the monthly commitment amounts to better align with working capital requirements. Under the 2019 Repurchase Facility, Historical 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 2019 Repurchase Facility is considered a secured borrowing with the customer notes receivable inclusive of those that are sold and repurchased, equal to 105 percent of the outstanding amounts borrowed utilized as collateral. Borrowings under the 2019 Repurchase Facility have an interest rate of LIBOR + 0.75 percent . As of March 31, 2019, $20 million of notes receivable, recorded in accounts and notes receivable - net, were pledged as collateral against outstanding borrowings under the 2019 Repurchase Facility of $19 million , recorded in short-term borrowings and finance 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 (the "Term Loan Facility") under which Historical 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 were used for the company's general corporate purposes including debt repayment, working capital and funding a portion of DowDuPont's costs and expenses. At March 31, 2019, the company had made six term loan borrowings in an aggregate principal amount of $3,000 million and had unused commitments of $1,500 million under the Term Loan Facility. See Note 18 for further discussion on the repayment of the term loan in May 2019.

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, 2019 , 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, and customers. At March 31, 2019 and December 31, 2018 , the company had directly guaranteed $239 million and $259 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. Assuming liquidation, these assets are estimated to cover approximately 7 percent of the $73 million of guaranteed obligations of customers. Set forth below are the company's guaranteed obligations at March 31, 2019. The following table provides a summary of the final expiration year and maximum future payments for each type of guarantee: Guarantees at March 31, 2019 Final Expiration Year Maximum Future Payments (In millions) Obligations for customers 1 : Bank borrowings 2022 $ 73 Obligations for non-consolidated affiliates 2 : Bank borrowings 2019 166 Total guarantees $ 239 1. Existing guarantees for select customers, as part of contractual agreements. The terms of the guarantees are equivalent to the terms of the customer loans that are primarily made to finance customer invoices. Of the total maximum future payments, $72 million had terms less than a year. 2. Existing guarantees for non-consolidated affiliates' liquidity needs in normal operations. 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 Liabilities Historical DuPont is a party to legal proceedings relating to the use of PFOA (collectively, perfluorooctanoic acids and its salts, including the ammonium salt) by its former Performance Chemicals segment, which separated from Historical DuPont in July 2015 through the spin-off of all the issued and outstanding stock of Chemours. While it is reasonably possible that the company could incur liabilities related to PFOA, any such liabilities are not expected to be material. As discussed in Note 3 and below, the company is indemnified by Chemours under the Chemours Separation Agreement, as amended. The company has recorded a liability of $22 million and an indemnification asset of $22 million at March 31, 2019 , primarily related to testing drinking water in and around certain historic 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. Leach Settlement and MDL Settlement Historical DuPont has residual liabilities under its 2004 settlement of a West Virginia state court class action, Leach v. DuPont, which alleged that PFOA from Historical DuPont’s former Washington Works facility had contaminated area drinking water supplies and affected the health of area residents. The settlement class has about 80,000 members. In addition to relief that was provided to class members years ago, the settlement requires Historical DuPont to continue providing PFOA water treatment to six area water districts and private well users and to fund, through an escrow account, up to $235 million for a medical monitoring program for eligible class members. As of March 31, 2019 , approximately $2 million had been disbursed from the account since its establishment in 2012 and the remaining balance is approximately $1 million . The Leach settlement permits class members to pursue personal injury claims for six health conditions (and no others) that an expert panel appointed under the settlement reported in 2012 had a “probable link” (as defined in the settlement) with PFOA: pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol. After the expert panel reported its findings, approximately 3,550 personal injury lawsuits were filed in federal and state courts in Ohio and West Virginia and consolidated in multi-district litigation in the U.S. District Court for the Southern District of Ohio (“MDL”). The MDL was settled in early 2017 for $670.7 million in cash, with Chemours and Historical DuPont (without indemnification from Chemours) each paying half. 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, 2019 , approximately 57 lawsuits were pending alleging personal injury, including kidney and testicular cancer, thyroid disease and ulcerative colitis, from exposure to PFOA through air or water, only 3 of which are not part of the MDL or were not otherwise filed on behalf of Leach class members. Other PFOA Actions Historical DuPont is a party to other PFOA lawsuits that do not involve claims for personal injury. Chemours, pursuant to the Chemours Separation Agreement, is defending and indemnifying, with reservation, the company in these lawsuits. New York . Historical DuPont is a defendant in about 52 lawsuits, including a putative class action, brought by persons who live in and around Hoosick Falls, New York. These lawsuits assert claims for medical monitoring and property damage based on alleged PFOA releases from manufacturing facilities owned and operated by co-defendants in Hoosick Falls and allege that Historical DuPont and 3M supplied some of the materials used at these facilities. Historical DuPont is also one of more than ten defendants in a lawsuit brought by the Town of East Hampton, New York alleging PFOA and perfluorooctanesulfonic acid ("PFOS") contamination of the town’s well water. New Jersey . At December 31, 2018, two lawsuits were pending, one brought by a local water utility and the second a putative class action, against Historical DuPont alleging that PFOA from Historical DuPont’s former Chambers Works facility contaminated drinking water sources. The putative class action was dismissed without prejudice by the plaintiffs. In late March of 2019, the New Jersey State Attorney General (the “NJAG”) filed four lawsuits against the company, Chemours, 3M and others alleging that former Historical DuPont operations at the Chambers Works, Pompton Lakes Works, Parlin and Repauno sites in New Jersey, caused damage to the State’s natural resources. Two of these lawsuits (those involving the Chambers Works and Parlin sites) allege contamination from per- and polyfluoroalkyl substances (“PFAS”). The lawsuit related to Parlin names an additional DowDuPont subsidiary. The Ridgewood Water District in New Jersey filed suit in the first quarter 2019 against Historical DuPont alleging losses related to the investigation, remediation and monitoring of polyfluorinated surfactants (“PFS”), including PFOA, in water supplies. Alabama . Historical DuPont is one of more than thirty defendants in one lawsuit by a local water utility alleging contamination from perfluorinated chemicals and compounds (“PFCs”), including PFOA, used by co-defendant carpet manufacturers to make their products more stain and grease resistant. Ohio . Historical DuPont is a defendant in three lawsuits: an action by the State of Ohio based on alleged damage to natural resources, a putative nationwide class action brought on behalf of anyone who has detectable levels of perfluorinated chemicals, including PFOA, in their blood, and an action by the City of Dayton claiming losses related to the investigation, remediation and monitoring of PFAS, including PFOA, in water supplies. Other . Dozens of cases have been filed against 3M and other defendants primarily alleging property damage from contamination in connection with the use of firefighting foams that contain PFOS. At March 31, 2019 , Historical DuPont was named in 4 of these cases. Historical DuPont did not make firefighting foam and has never made or supplied PFOS or products that contained PFOS. Chemours Separation Agreement Amendment As discussed in Note 3 , concurrent with the MDL Settlement, Historical DuPont and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future PFOA liabilities for a five -year period that began on July 6, 2017. During that five -year period, Chemours will annually pay the first $25 million of future PFOA liabilities and, if that amount is exceeded, Historical DuPont will pay any excess amount up to the next $25 million , with Chemours annually bearing any excess liabilities above that amount. At the end of the five -year period, this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Chemours Separation Agreement will continue unchanged. As part of this amendment, Chemours also agreed that it would not contest its liability for PFOA liabilities on the basis of certain ostensible defenses it had previously raised, including defenses relating to punitive damages, and would waive 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 Chemours Separation Agreement. There have been no charges incurred by Historical DuPont under this arrangement through March 31, 2019 . 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 in Bladen County, North Carolina. The facility is now owned and operated by Chemours, which continues to manufacture and use GenX. In 2017, the facility became and continues to be the subject of inquiries and government investigations relating to the alleged discharge of GenX and certain similar compounds into the air and Cape Fear River. 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 documents related to these discharges. Historical DuPont was served with additional subpoenas relating to the same issue and in the second quarter 2018, received a subpoena expanding the scope to any PFCs discharged from the Fayetteville Works facility into the Cape Fear River. 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, the company, or both. At March 31, 2019 , several actions are pending in federal court against Chemours and the company. One of these actions is a consolidated putative class action that asserts claims for medical monitoring and property damage on behalf of putative classes of property owners and residents in areas near or who draw drinking water from the Cape Fear River. Another action is a consolidated action brought by various North Carolina water authorities, including the Cape Fear Public Utility Authority and Brunswick County, that seek actual and punitive damages as well as injunctive relief. In addition, an action is pending in North Carolina state court on behalf of about 100 plaintiffs who own wells and property near the Fayetteville Works facility. The plaintiffs seek damages for nuisance allegedly caused by releases of certain PFCs from the site. While it is reasonably possible that the company could incur liabilities related to the actions described above, any such liabilities are not expected to be material. 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, 2019 , Chemours, with reservations, 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, 2019 , the company had accrued obligations of $384 million for probable environmental remediation and restoration costs, including $54 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 $790 million above the amount accrued at March 31, 2019 . 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. 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 Chemours Separation Agreement, the company is indemnified by Chemours for certain environmental matters, included in the liability of $384 million , that have an estimated liability of $185 million as of March 31, 2019 , and a potential exposure that ranges up to approximately $355 million above the amount accrued. As such, the company has recorded an indemnification asset of $185 million corresponding to the company’s accrual balance related to these matters at March 31, 2019 , including $35 million related to the Superfund sites.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments Disclosure [Text Block]	FINANCIAL INSTRUMENTS At March 31, 2019 , the company had $2,750 million ( $3,551 million at December 31, 2018 ) 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 $18 million ( $34 million at December 31, 2018 ) 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. 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 non-derivatives 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 (In millions) March 31, 2019 December 31, 2018 Derivatives designated as hedging instruments: Commodity contracts $ 351 $ 525 Derivatives not designated as hedging instruments: Foreign currency contracts $ 1,442 $ 2,057 Commodity contracts $ 125 $ 9 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, after 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 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: Three Months Ended March 31, (In millions) 2019 2018 Beginning balance $ (26 ) $ (2 ) Additions and revaluations of derivatives designated as cash flow hedges 4 12 Clearance of hedge results to earnings (3 ) (1 ) Ending balance $ (25 ) $ 9 At March 31, 2019 , an after-tax net loss of $10 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.

Subsequent Events [Abstract]
Subsequent Events [Text Block]	SUBSEQUENT EVENTS Intended Business Separations Prior to the Dow Distribution, Historical Dow conveyed or transferred the assets and liabilities aligned with Historical Dow’s agriculture business to separate legal entities (“DAS”) and the assets and liabilities associated with its specialty products business to separate legal entities (the “SP Entities”). On April 1, 2019, DAS and the SP Entities were transferred and conveyed to DowDuPont. In furtherance of the Intended Business Separations, the company engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization”) to realign its businesses into three subgroups: agriculture, materials science and specialty products. As part of the Internal Reorganization: • the assets and liabilities aligned with the company’s materials science business, including Historical DuPont’s ethylene and ethylene copolymers business, excluding its ethylene acrylic elastomers business, (“ECP”) were transferred or conveyed to separate legal entities (the “Materials Science Entities”) that were ultimately conveyed by DowDuPont to Dow; • the assets and liabilities aligned with the company’s specialty products business were transferred or conveyed to separate legal entities (“Specialty Products Entities”); • on April 1, 2019, Historical DuPont transferred and conveyed its Materials Science Entities to DowDuPont; • on May 1, 2019, Historical DuPont distributed its Special Products Entities to DowDuPont; and • on May 2, 2019, DowDuPont conveyed DAS to the company; in connection with the foregoing, the company issued additional shares of its Common Stock to DowDuPont. As a result of the foregoing, at May 2, 2019, the company holds all or substantially all the assets and liabilities associated with DowDuPont’s combined agriculture business. Beginning in the second quarter of 2019, ECP’s financial results for periods prior to April 1, 2019 will be reflected in Historical DuPont's Consolidated Financial Statements as a discontinued operation. Historical DuPont’s specialty products businesses financial results for periods prior to May 1, 2019, will also be reflected in the company’s Consolidated Financial Statements as a discontinued operation beginning in the second quarter of 2019. The transfer or conveyance of DAS to Historical DuPont will be treated as a transfer of entities under common control. As such, Historical DuPont will record the assets, liabilities, and equity of DAS on its balance sheet at their historical basis. Transfers of businesses between entities under common control requires the financial statements to be presented as if the transaction had occurred at the point at which common control first existed (the "Effective Time of the Merger"). Beginning in the second quarter of 2019, Historical DuPont’s historical financial statements and related notes will be revised to include the historical balances of DAS as of September 1, 2017. Separation Agreements In connection with the Dow Distribution and the intended Corteva Distribution, DowDuPont has entered into or will enter into certain agreements that will effect the separation, provide for the allocation of DowDuPont’s assets, employees, liabilities and obligations (including its investments, property and employee benefits and tax-related assets and liabilities) among DowDuPont, Dow, and Corteva (together, the “Parties” and each a “Party”) , and provide a framework for DowDuPont’s relationship with Dow and Corteva following the separations and Distributions. Effective April 1, 2019, the Parties entered into the following agreements: • Separation and Distribution Agreement - The Parties entered into an agreement that sets forth, among other things, the agreements among the Parties regarding the principal transactions necessary to effect the Distributions. It also sets forth other agreements that govern certain aspects of the Parties’ ongoing relationships after the completion of the Distributions (the "Separation and Distribution Agreement"). • Tax Matters Agreement - The Parties entered into an agreement that governs their respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. • Employee Matters Agreement - The Parties entered into an agreement that identifies employees and employee-related liabilities (and attributable assets) to be allocated (either retained, transferred and accepted, or assigned and assumed, as applicable) to the Parties as part of the Distributions and describes when and how the relevant transfers and assignments will occur. • Intellectual Property Cross-License Agreements - Dow and Corteva entered into an Intellectual Property Cross-License Agreement (the “Dow-Corteva IP Cross-License Agreement”). The Intellectual Property Cross-License Agreements set forth the terms and conditions under which the applicable Parties may use in their respective businesses, following each of the Distributions, certain know-how (including trade secrets), copyrights, and software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement. In connection with the intended Corteva Distribution, DowDuPont expects to enter into additional agreements, including an intellectual property cross-license agreement with Corteva. This agreement will set forth the terms and conditions under which DowDuPont and Corteva may use, in their respective businesses following the Corteva Distribution, certain know-how (including trade secrets), copyrights, and software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement. Debt Redemptions/Repayments On March 22, 2019, Historical DuPont issued notices of redemption in full of all of its outstanding notes (the “Make Whole Notes”) listed in the table below: (in millions) Amount 4.625% Notes due 2020 $ 474 3.625% Notes due 2021 296 4.250% Notes due 2021 163 2.800% Notes due 2023 381 6.500% Debentures due 2028 57 5.600% Senior Notes due 2036 42 4.900% Notes due 2041 48 4.150% Notes due 2043 69 Total $ 1,530 The Make Whole Notes were redeemed on April 22, 2019 at the make-whole redemption prices set forth in the respective Make Whole Notes. On and after the date of redemption, the Make Whole Notes were no longer deemed outstanding, interest on the Make Whole Notes ceased to accrue and all rights of the holders of the Make Whole Notes were terminated. On May 2, 2019 Historical DuPont terminated its Term Loan Facility and repaid the aggregate outstanding principal amount of $3 billion plus accrued and unpaid interest through and including May 1, 2019. In connection with the foregoing, Historical DuPont paid a total of $4.6 billion , which included breakage fees and accrued and unpaid interest on the Make Whole Notes and Term Loan Facility. The company funded the payments with cash from operations and a related party revolving loan of $4.1 billion from Corteva, Inc. with an interest rate of 4.275% , repayable in 5 years . Corteva, Inc. funded its loan to the company with contributions from DowDuPont. Historical DuPont anticipates the loss on the early extinguishment of debt to be approximately $18 million related to the difference between the redemption price and the par value of the Make Whole Notes and Term Loan Facility, partially offset by the write-off of unamortized step-up related to the fair value step-up of Historical DuPont’s debt. On May 7, 2019 , DowDuPont publicly announced the record date in connection with the intended Corteva Distribution. In connection with such announcement, the company will be required to mail a notice of redemption to holders of the $1,250 million aggregate principal amount of 2.200% Notes due 2020 and $750 million aggregate principal amount of Floating Rate Notes due 2020 (collectively, the “SMR Notes”) setting forth the date of redemption of the SMR Notes. The date of redemption will be on or before May 24, 2019. On the date of redemption, the company will be required to redeem all of the SMR Notes at a redemption price equal to 100% of the aggregate principal amount of the SMR Notes plus accrued and unpaid interest, if any, up to but excluding the date of redemption. Following the redemption, the SMR Notes will no longer be outstanding and will cease to bear interest and all rights of the holders of the SMR Notes will terminate. Historical DuPont believes the redemption will be funded with a draw down on the related party revolving loan from Corteva, however, the actual redemption could be funded through a combination of the related party loan and contributions.

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, 2018, collectively referred to as the “2018 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 [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 ("Historical Dow") and Historical 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"), Historical Dow and Historical DuPont each merged with wholly owned subsidiaries of DowDuPont ("Mergers") and, as a result of the Mergers, Historical Dow and Historical 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 U.S. Securities and Exchange Commission ("SEC") 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" and the transactions to accomplish the Intended Business Separations, the "separations").
Intended Business Separations [Policy Text Block]	On February 26, 2018, DowDuPont announced the corporate brand names that each company plans to assume once the Intended Business Separations occur. Materials science is called Dow, agriculture will be called Corteva TM Agriscience, and specialty products will be called DuPont. Effective as of 5:00 pm ET on April 1, 2019, DowDuPont completed the previously announced separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock, par value $0.01 per share (the “Dow Common Stock”), to holders of DowDuPont's common stock, par value $0.01 per share (the “DowDuPont Common Stock”), as of the close of business on March 21, 2019 (the “Dow Distribution”). DowDuPont expects to complete the previously announced intended separation of its agriculture business into a separate and independent public company on June 1, 2019 by way of a distribution of Corteva, Inc., a Delaware corporation and wholly-owned subsidiary of DowDuPont (“Corteva”), through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Corteva’s common stock, par value $0.01 per share, to holders of DowDuPont Common Stock as of a record date to be set by DowDuPont’s Board of Directors (the “Corteva Distribution” and, together with the Dow Distribution, the “Distributions”). Refer to Notes 3 and 18 for additional information.
Related Party Transactions [Policy Text Block]	Transactions between Historical DuPont and DowDuPont, Historical Dow and their affiliates and other associated companies are reflected in the Consolidated Financial Statements and disclosed as related party transactions when material. Related party transactions with Historical Dow and DowDuPont are included in Note 6 .
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 Historical 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 Historical 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 the three months ended March 31, 2018. 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 the three months ended March 31, 2018. 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.

Lessee, Leases [Policy Text Block]	The company has updated its leasing policy since the issuance of its 2018 Annual Report as a result of the adoption of ASU No. 2016-02, Leases (Topic 842) in the first quarter 2019. See Notes 2 and 11 for additional information. See Note 1, "Summary of Significant Accounting Policies," in the 2018 Annual Report for more information on Historical DuPont's other significant accounting policies. Leases The company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and the company has the right to control the asset. Operating lease right-of-use ("ROU") assets are included in other assets on the company’s Consolidated Balance Sheets. Operating lease liabilities are included in accrued and other current liabilities and other noncurrent obligations on the company’s Consolidated Balance Sheets. Finance lease assets are included in property, plant and equipment on the company’s Consolidated Balance Sheets. Finance lease liabilities are included in short-term borrowings and finance lease obligations and long-term debt on the company’s Consolidated Balance Sheets. Operating lease ROU assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the company’s leases do not provide the lessor's implicit rate, the company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The company recognizes lease expense for these leases on a straight-line basis over the lease term. The company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. In the Consolidated Statements of Operations, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. The company has operating and finance leases for real estate, airplanes, railcars, fleet, certain machinery and equipment, and information technology assets. The company’s leases have remaining lease terms of 1 year to 50 years . For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend the lease when it is reasonably certain that the company will exercise that option. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments.

Accounting Policies [Abstract]
Recent Accounting Guidance	Recently Adopted Accounting Guidance In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on their balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from previous U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance issued in 2014 (Topic 606). The company adopted this standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 (Leases). In addition, the company has elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, does not require reassessment of prior conclusions related to contracts containing a lease, lease classification, and initial direct lease costs. As an accounting policy election, the company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and will account for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the company’s interim Condensed Consolidated Balance Sheet: (In millions) As Reported December 31, 2018 Effect of Adoption of ASU 2016-02 Updated January 1, 2019 Assets Property, plant and equipment - net of accumulated depreciation $ 12,186 $ 9 $ 12,195 Other assets $ 1,810 $ 758 $ 2,568 Liabilities and Equity Current liabilities Short-term borrowings and finance lease obligations $ 2,160 $ 1 $ 2,161 Accrued and other current liabilities $ 4,233 $ 234 $ 4,467 Long-Term Debt $ 5,812 $ 8 $ 5,820 Other noncurrent obligations $ 1,620 $ 524 $ 2,144 The adoption of the new guidance did not have a material impact on the company's interim Consolidated Statement of Operations and had no impact on the interim Condensed Consolidated Statement of Cash Flows.

Revenue from Contract with Customer [Abstract]
Revenue Recognition, Sales of Goods	Products Substantially all of Historical DuPont's revenue is derived from product sales. Product sales consist of sales of Historical DuPont's products to supply manufacturers, distributors, and farmers. Historical 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 Recognition, Licenses of Intellectual Property	Licenses of Intellectual Property Historical 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.
