Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Interim Financial Statements
	The accompanying unaudited 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, 2014, collectively referred to as the “2014 Annual Report”.  The Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained, as well as variable interest entities for which DuPont is the primary beneficiary.
	Basis of Presentation
	Certain reclassifications of prior year's data have been made to conform to current year's presentation.
	The company’s cost structure has been impacted by the global, multi-year initiative to redesign its global organization and operating model to improve productivity and agility across all businesses and functions. Effective December 31, 2014, in order to better align to the transforming company’s organization and resulting cost structure, certain costs were reclassified from other operating charges to selling, general and administrative expenses. Prior year data has been reclassified to conform to current year presentation.   Other operating charges primarily include, costs associated with the Performance Chemical separation, product claim charges and non-capitalizable costs associated with capital projects. Selling, general and administrative expense primarily includes selling and marketing expenses, commissions, functional costs, and business management expenses.
	Foreign Currency Translation
	The company's worldwide operations utilize the U.S. dollar (USD) or local currency as the functional currency, where applicable. The company identifies its separate and distinct foreign entities and groups the foreign entities into two categories: 1) extension of the parent (USD functional currency) and 2) self-contained (local functional currency). If a foreign entity does not clearly align with either category, factors are evaluated and a judgment is made to determine the functional currency.
	For foreign entities where the USD is the functional currency, all foreign currency asset and liability amounts are remeasured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.
	For foreign entities where the local currency is the functional currency, assets and liabilities denominated in local currencies are translated into USD at end-of-period exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the local currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during the period.
	The company changes the functional currency of its separate and distinct foreign entities only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed. As a result of the planned separation of its Performance Chemicals segment, coupled with the Company’s redesign initiative, the functional currency at certain of the company’s foreign entities is being re-evaluated which, in some cases, has resulted in a change in the foreign entities’ functional currency during the first quarter of 2015.
	Venezuelan Foreign Currency
	Venezuela is considered a highly inflationary economy under GAAP and the USD is the functional currency for the company's subsidiaries in Venezuela. The official exchange rate continues to be set through the National Center for Foreign Commerce (CENCOEX, previously CADIVI). Based on its evaluation of the restrictions and limitations affecting the availability of specific exchange rate mechanisms, management concluded in the second quarter of 2014 that the SICAD 2 auction process would be the most likely mechanism available. As a result, in the second quarter of 2014, the company changed from the official exchange rate to the SICAD 2 exchange rate.
	During the first quarter of 2015, the Venezuelan government enacted additional changes to the country’s foreign exchange systems including the replacement of SICAD 2 and introduction of the SIMADI (Foreign Exchange Marginal System) auction process. Given the replacement of SICAD 2 with SIMADI, management has concluded that the SIMADI auction process would be the most likely exchange mechanism available. As a result, effective in the first quarter of 2015, the company changed from the SICAD 2 to the SIMADI exchange rate, to remeasure its Bolivar Fuertes (VEF) denominated net monetary assets which resulted in a pre-tax charge of $3 recorded within other income, net in the company’s interim Consolidated Income Statements for the three months ended March 31, 2015. The remaining net monetary assets and non-monetary assets are immaterial at March 31, 2015.
	Recent Accounting Pronouncements
	In February 2015, the FASB issued ASU No. 2015-02 Consolidation (Topic 810), Amendments to the Consolidation Analysis. The amendments under the new guidance modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminate the presumption that a general partner should consolidate a limited partnership. The ASU is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. A reporting entity also may apply the amendments retrospectively. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
	In May 2014, the FASB and the International Accounting Standards Board (IASB) jointly issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (IFRS). 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 ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. The FASB proposed that a deferral of the effective date is necessary to provide adequate time to effectively implement the new revenue standard. It is important to note that the FASB’s proposed deferral is not a final decision. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
	In April 2014, the FASB issued authoritative guidance amending existing requirements for reporting discontinued operations.  Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. Public entities will apply the amended guidance prospectively to all disposals occurring within annual periods beginning on or after December 15, 2014 and interim periods within those years. The company adopted this standard on January 1, 2015. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under previous standards.

	Performance Chemicals
	On October 24, 2013, DuPont announced that it intends to separate its Performance Chemicals segment through a U.S. tax-free spin-off to shareholders, subject to customary closing conditions. The company expects to complete the separation on July 1, 2015, subject to final approval from DuPont's Board of Directors. During the three months ended March 31, 2015 and 2014, respectively, the company incurred $81 and $16 of costs associated with the transaction which were reported in other operating charges in the company's interim Consolidated Income Statements. These transaction costs primarily relate to professional fees associated with preparation of regulatory filings and separation activities within finance, legal and information system functions.

Employee Separation / Asset Related Charges, Net	Employee Separation / Asset Related Charges, Net
	During first quarter of 2015, a $38 pre-tax impairment charge was recorded in employee separation / asset related charges, net within the Other segment. The majority relates to a cost basis investment in which the assessment resulted from the venture's revised operating plan reflecting underperformance of its European wheat based ethanol facility and deteriorating European ethanol market conditions. One of the primary investors has communicated they would not fund the revised operating plan of the investee. As a result, the carrying value of our 6 percent cost basis investment in this venture exceeded its fair value by $37, such that an impairment charge was required.
	2014 Restructuring Program
	At March 31, 2015, total liabilities related to the 2014 restructuring program were $223. A complete discussion of restructuring initiatives is included in the company's 2014 Annual Report in Note 3, "Employee Separation / Asset Related Charges, Net."
	Account balances for the 2014 restructuring program are summarized below:

	1	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 net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on the company's interim Consolidated Income Statements. The increase in pre-tax exchange gains over prior year was driven by gains on foreign currency contracts due to strengthening of the USD versus global currencies partially offset by losses on the related foreign currency-denominated monetary assets and liabilities. The $64 net exchange gain for the three months ended March 31, 2015, includes a $(40) pre-tax exchange loss, $(38) after-tax, associated with the devaluation of the Ukrainian hryvnia. The $(96) net exchange loss for the three months ended March 31, 2014, includes a $(39) pre-tax exchange loss, $(27) after-tax, associated with the devaluation of the Ukrainian hryvnia.

Provision for Income Taxes	Income Taxes
	In the first quarter 2015, the company recorded a tax provision of $566, including $212 of tax expense associated with the company’s policy of hedging the foreign currency-denominated monetary assets and liabilities of its operations and gains or losses on foreign currency contracts.
	In the first quarter 2014, the company recorded a tax provision of $357, including $28 of tax benefit associated with the company's policy of hedging the foreign currency-denominated monetary assets and liabilities of its operations and gains or losses on foreign currency contracts.
	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. It is reasonably possible that net reductions to the company’s global unrecognized tax benefits could be in the range of $100 to $125 within the next twelve months with the majority due to the settlement of uncertain tax positions with various tax authorities.

	Guarantees
	Indemnifications
	In connection with acquisitions and divestitures, 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 transaction. 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, 2015 and December 31, 2014, the company had directly guaranteed $498 and $513, 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 47 percent of the $315 of guaranteed obligations of customers and suppliers. Set forth below are the company's guaranteed obligations at March 31, 2015:
		Short-Term		Long-Term		Total
	Obligations for customers and suppliers1:
	Bank borrowings (terms up to 7 years)	$	230	$	84	$	314

	Imprelis®
	The company has received claims and lawsuits alleging that the use of Imprelis® herbicide caused damage to certain trees. Sales of Imprelis® were suspended in August 2011 and the product was last applied during the 2011 spring application season. The lawsuits seeking class action status were consolidated in multidistrict litigation in federal court in Philadelphia, Pennsylvania. In February 2014, the court entered the final order dismissing these lawsuits as a result of the class action settlement.
	As part of the settlement, DuPont paid about $7 in plaintiffs' attorney fees and expenses. In addition, DuPont is providing a warranty against new damage, if any, caused by the use of Imprelis® on class members' properties through May 2015. Certain class members opted out of the class action settlement and made independent claims or filed suit in various state courts, the majority of which were removed to federal court in Philadelphia. In the third quarter 2014, the company settled or reached settlements in principle for the majority of these claims and lawsuits. About 37 lawsuits are pending claiming property and related damage at March 31, 2015. This represents a decrease of 3 from the number of lawsuits pending at December 31, 2014.
	The company has established review processes to verify and evaluate damage claims. There are several variables that impact the evaluation process including the number of trees on a property, the species of tree with reported damage, the height of the tree, the extent of damage and the possibility for trees to naturally recover over time. Upon receiving claims, DuPont verifies their accuracy and validity which often requires physical review of the property.
	DuPont recorded income of $35 for insurance recoveries, within other operating charges in the interim Consolidated Income Statements, for the three months ended March 31, 2015. At March 31, 2015, DuPont had an accrual balance of $231 related to these claims and insurance receivables of $25.
	Insurance recoveries are recognized when collection of payment is considered probable. The remaining coverage under the insurance program is $300 for costs and expenses. DuPont has submitted requests for payment to its insurance carriers for costs associated with this matter. The timing and outcome remain uncertain.
	Litigation
	The company is subject to various legal proceedings arising out of the normal course of its business 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
	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. At March 31, 2015, DuPont has an accrual balance of $14 related to the PFOA matters discussed below.
	The accrual includes charges related to DuPont's obligations under agreements with the U.S. Environmental Protection Agency and voluntary commitments to the New Jersey Department of Environmental Protection.  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 Provisional Health Advisory.
	Drinking Water Actions
	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.
	DuPont and attorneys for the class reached a settlement in 2004 that binds about 80,000 residents. In 2005, DuPont paid the plaintiffs’ attorneys’ fees and expenses of $23 and made a payment of $70, which class counsel designated to fund a community health project.  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 studies were conducted in communities exposed to PFOA to evaluate available scientific evidence on whether any probable link exists, as defined in the settlement agreement, between exposure to PFOA and human disease.
	The C8 Science Panel found probable links, as defined in the settlement agreement, between exposure to PFOA and pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol.
	In May 2013, a panel of three independent medical doctors released its initial recommendations for screening and diagnostic testing of eligible class members. In September 2014, the medical panel recommended follow-up screening and diagnostic testing three years after initial testing, based on individual results. The medical panel has not communicated its anticipated schedule for completion of its protocol. The company is obligated to fund up to $235 for a medical monitoring program for eligible class members and, in addition, administrative costs associated with the program, including class counsel fees.  In January 2012, the company put $1 in an escrow account to fund medical monitoring as required by the settlement agreement.  The court appointed Director of Medical Monitoring has established the program to implement the medical panel's recommendations and the registration process, as well as eligibility screening, is ongoing. Diagnostic screening and testing has begun and associated payments to service providers are being disbursed from the escrow account.
	In addition, under the settlement agreement, the company 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 (LHWA), and private well users.
	Class members may pursue personal injury claims against DuPont only for those human diseases for which the C8 Science Panel determined a probable link exists. At March 31, 2015, there were approximately 3,500 lawsuits filed in various federal and state courts in Ohio and West Virginia, an increase of about 600 over December 31, 2014. In accordance with a stipulation reached in the third quarter 2014 and other court procedures, these lawsuits have been or will be served and consolidated in multi-district litigation in Ohio federal court (MDL). Based on information currently available to the company the majority of the lawsuits allege personal injury claims associated with high cholesterol and thyroid disease from exposure to PFOA in drinking water.  There are 32 lawsuits alleging wrongful death. While attorneys for the plaintiffs have indicated that additional lawsuits may be filed, the company expects the rate of such filings to substantially decrease. In 2014, six plaintiffs from the MDL were selected for individual trial. The first trial is scheduled to begin in September 2015, and the second in November 2015. DuPont denies the allegations in these lawsuits and is defending itself vigorously.
	Additional Actions
	An Ohio action brought by the LHWA is ongoing. In addition to general claims of PFOA contamination of drinking water, the action claims “imminent and substantial endangerment to health and or the environment” under the Resource Conservation and Recovery Act (RCRA). In the second quarter 2014, DuPont filed a motion for summary judgment and LHWA moved for partial summary judgment. In the first quarter of 2015, the court granted in part and denied in part both parties’ motions. As a result, the litigation process will continue with respect to certain of the plaintiffs’ claims.
	PFOA Summary
	While it is probable that the company will incur costs related to funding the medical monitoring program, such costs cannot be reasonably estimated due to uncertainties surrounding the level of participation by eligible class members and the scope of testing. DuPont believes that it is reasonably possible that it could incur losses related to the other PFOA matters discussed above; however, a range of such losses, if any, cannot be reasonably estimated at this time, due to the uniqueness of the individual MDL plaintiff's claims and the company's defenses to those claims both as to potential liability and damages on an individual claims basis, among other factors.
	Environmental
	The company is also subject to contingencies pursuant to environmental laws and regulations that in the future may require the company to take further action to correct the effects on the environment of prior disposal practices or releases of chemical or petroleum substances by the company or other parties. The company accrues for environmental remediation activities consistent with the policy as described in the company's 2014 Annual Report in Note 1, “Summary of Significant Accounting Policies.” Much of this liability results from the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, often referred to as Superfund), Resource Conservation and Recovery Act (RCRA) and similar state and global laws. These laws require the company to undertake certain investigative, remediation and restoration activities at sites where the company conducts or once conducted operations or at sites where company-generated waste was disposed. The accrual also includes estimated costs related to a number of sites identified by the company for which it is probable that environmental remediation will be required, but which are not currently the subject of enforcement activities.
	Remediation activities vary substantially in duration and cost from site to site. These activities, and their associated costs, depend on the mix of unique site characteristics, evolving remediation technologies, diverse regulatory agencies and enforcement policies, as well as the presence or absence of potentially responsible parties. At March 31, 2015, the Condensed Consolidated Balance Sheet included a liability of $482, relating to these matters and, in management's opinion, is appropriate based on existing facts and circumstances. The average time frame over which the accrued or presently unrecognized amounts may be paid, based on past history, is estimated to be 15-20 years. Considerable uncertainty exists with respect to these costs and, under adverse changes in circumstances, the potential liability may range up to $1,100 above the amount accrued as of March 31, 2015.

Financial Instruments Disclosure [Abstract]
Financial Instruments	Financial Instruments
	Debt
	The estimated fair value of the company's total debt including interest rate financial instruments was determined using level 2 inputs within the fair value hierarchy, as described in the company's 2014 Annual Report in Note 1, “Summary of Significant Accounting Policies.” Based on quoted market prices for the same or similar issues or on current rates offered to the company for debt of the same remaining maturities, the fair value of the company's debt was approximately $11,168 and $11,394 as of March 31, 2015 and December 31, 2014, respectively.
	Cash Equivalents
	The fair value of cash equivalents approximates its stated value.  The estimated fair value of the company's cash equivalents was determined using level 1 and level 2 inputs within the fair value hierarchy, as described in the company's 2014 Annual Report in Note 1, “Summary of Significant Accounting Policies.”  Level 1 measurements are based on observable net asset values and level 2 measurements are based on current interest rates for similar investments with comparable credit risk and time to maturity.  The company held $0 and $1,436 of money market funds (level 1 measurements) as of March 31, 2015 and December 31, 2014, respectively.  The company held $1,700 and $3,293 of other cash equivalents (level 2 measurements) as of March 31, 2015 and December 31, 2014, 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's derivative assets and liabilities are reported on a gross basis in the Condensed Consolidated Balance Sheets. 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:
		March 31, 2015			December 31, 2014
	Derivatives designated as hedging instruments:
	Interest rate swaps	$	—		$	1,000
	Foreign currency contracts	71			434
	Commodity contracts	265			388
	Derivatives not designated as hedging instruments:
	Foreign currency contracts	8,959			10,586
	Commodity contracts	86			166
	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 and option 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 copper, corn, soybeans 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.
	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 occuring. The following table summarizes the after-tax effect of cash flow hedges on accumulated other comprehensive loss for the three months ended March 31, 2015 and 2014:
		Three Months Ended

		2015			2014

	Additions and revaluations of derivatives designated as cash flow hedges	(16		)	24
	Clearance of hedge results to earnings	4			11
	Ending balance	$	(18	)	$	(13	)
	At March 31, 2015, an after-tax net loss of $4 is expected to be reclassified from accumulated other comprehensive loss into earnings over the next 12 months.
	Derivatives not Designated in Hedging Relationships
	Foreign Currency Contracts
	The company routinely uses forward exchange and options 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.
	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 and soybean meal.
	Fair Values of Derivative Instruments
	The table below presents the fair values of the company's derivative assets and liabilities within the fair value hierarchy, as described in the company's 2014 Annual Report in Note 1, “Summary of Significant Accounting Policies.”

Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Interim Financial Statements
	The accompanying unaudited 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, 2014, collectively referred to as the “2014 Annual Report”.  The Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained, as well as variable interest entities for which DuPont is the primary beneficiary.
	Basis of Presentation
	Certain reclassifications of prior year's data have been made to conform to current year's presentation.
	The company’s cost structure has been impacted by the global, multi-year initiative to redesign its global organization and operating model to improve productivity and agility across all businesses and functions. Effective December 31, 2014, in order to better align to the transforming company’s organization and resulting cost structure, certain costs were reclassified from other operating charges to selling, general and administrative expenses. Prior year data has been reclassified to conform to current year presentation.   Other operating charges primarily include, costs associated with the Performance Chemical separation, product claim charges and non-capitalizable costs associated with capital projects. Selling, general and administrative expense primarily includes selling and marketing expenses, commissions, functional costs, and business management expenses.
Foreign Currency Translations Policy [Policy Text Block]	Foreign Currency Translation
	The company's worldwide operations utilize the U.S. dollar (USD) or local currency as the functional currency, where applicable. The company identifies its separate and distinct foreign entities and groups the foreign entities into two categories: 1) extension of the parent (USD functional currency) and 2) self-contained (local functional currency). If a foreign entity does not clearly align with either category, factors are evaluated and a judgment is made to determine the functional currency.
	For foreign entities where the USD is the functional currency, all foreign currency asset and liability amounts are remeasured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.
	For foreign entities where the local currency is the functional currency, assets and liabilities denominated in local currencies are translated into USD at end-of-period exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the local currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during the period.
	The company changes the functional currency of its separate and distinct foreign entities only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed. As a result of the planned separation of its Performance Chemicals segment, coupled with the Company’s redesign initiative, the functional currency at certain of the company’s foreign entities is being re-evaluated which, in some cases, has resulted in a change in the foreign entities’ functional currency during the first quarter of 2015.
	Venezuelan Foreign Currency
	Venezuela is considered a highly inflationary economy under GAAP and the USD is the functional currency for the company's subsidiaries in Venezuela. The official exchange rate continues to be set through the National Center for Foreign Commerce (CENCOEX, previously CADIVI). Based on its evaluation of the restrictions and limitations affecting the availability of specific exchange rate mechanisms, management concluded in the second quarter of 2014 that the SICAD 2 auction process would be the most likely mechanism available. As a result, in the second quarter of 2014, the company changed from the official exchange rate to the SICAD 2 exchange rate.
	During the first quarter of 2015, the Venezuelan government enacted additional changes to the country’s foreign exchange systems including the replacement of SICAD 2 and introduction of the SIMADI (Foreign Exchange Marginal System) auction process. Given the replacement of SICAD 2 with SIMADI, management has concluded that the SIMADI auction process would be the most likely exchange mechanism available. As a result, effective in the first quarter of 2015, the company changed from the SICAD 2 to the SIMADI exchange rate, to remeasure its Bolivar Fuertes (VEF) denominated net monetary assets which resulted in a pre-tax charge of $3 recorded within other income, net in the company’s interim Consolidated Income Statements for the three months ended March 31, 2015. The remaining net monetary assets and non-monetary assets are immaterial at March 31, 2015.
Recent Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements
	In February 2015, the FASB issued ASU No. 2015-02 Consolidation (Topic 810), Amendments to the Consolidation Analysis. The amendments under the new guidance modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminate the presumption that a general partner should consolidate a limited partnership. The ASU is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. A reporting entity also may apply the amendments retrospectively. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
	In May 2014, the FASB and the International Accounting Standards Board (IASB) jointly issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (IFRS). 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 ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. The FASB proposed that a deferral of the effective date is necessary to provide adequate time to effectively implement the new revenue standard. It is important to note that the FASB’s proposed deferral is not a final decision. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
	In April 2014, the FASB issued authoritative guidance amending existing requirements for reporting discontinued operations.  Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. Public entities will apply the amended guidance prospectively to all disposals occurring within annual periods beginning on or after December 15, 2014 and interim periods within those years. The company adopted this standard on January 1, 2015. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under previous standards.

	1	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 net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on the company's interim Consolidated Income Statements. The increase in pre-tax exchange gains over prior year was driven by gains on foreign currency contracts due to strengthening of the USD versus global currencies partially offset by losses on the related foreign currency-denominated monetary assets and liabilities. The $64 net exchange gain for the three months ended March 31, 2015, includes a $(40) pre-tax exchange loss, $(38) after-tax, associated with the devaluation of the Ukrainian hryvnia. The $(96) net exchange loss for the three months ended March 31, 2014, includes a $(39) pre-tax exchange loss, $(27) after-tax, associated with the devaluation of the Ukrainian hryvnia.
	2	Miscellaneous income and expenses, net, includes interest items, certain insurance recoveries and litigation settlements and other items.

[1]	Included a charge of $(40) associated with remeasuring the company's Ukranian hryvnia net monetary assets in the three months ended March 31, 2015, which was recorded in other income, net in the company's interim Consolidated Income Statements.
[2]	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 net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on the company's interim Consolidated Income Statements. The increase in pre-tax exchange gains over prior year was driven by gains on foreign currency contracts due to strengthening of the USD versus global currencies partially offset by losses on the related foreign currency-denominated monetary assets and liabilities. The $64 net exchange gain for the three months ended MarchB 31, 2015, includes a $(40) pre-tax exchange loss, $(38) after-tax, associated with the devaluation of the Ukrainian hryvnia. The $(96) net exchange loss for the three months ended MarchB 31, 2014, includes a $(39) pre-tax exchange loss, $(27) after-tax, associated with the devaluation of the Ukrainian hryvnia
