Intended Business Separations [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BACKGROUND AND BASIS OF PRESENTATION Corteva, Inc. is a leading global provider of seed and crop protection solutions focused on the agriculture industry. The company intends to leverage its rich heritage of scientific achievement to advance its robust innovation pipeline and continue to shape the future of responsible agriculture. The company's broad portfolio of agriculture solutions fuels farmer productivity around the globe. Corteva has two reportable segments: seed and crop protection. See Note 22 - Segment Information, to the Consolidated Financial Statements, for additional information on the company's reportable segments. Throughout these financial statements, except as otherwise noted by the context, the terms "Corteva" or "company" used herein mean Corteva, Inc. and its consolidated subsidiaries (including EIDP) and the term “EIDP” used herein means EIDP, Inc. (formerly known as E. I. du Pont de Nemours and Company) and its consolidated subsidiaries or EIDP, Inc. excluding its consolidated subsidiaries, as the context may indicate. Principles of Consolidation and Basis of Presentation On June 1, 2019, Corteva, Inc. became an independent, publicly traded company through the completed separation (the “Separation”) of the agriculture business of DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.) (“DowDuPont” or “DuPont”). The separation was effectuated through a pro rata distribution (the “Corteva Distribution”) of all of the then-issued and outstanding shares of common stock of Corteva, Inc. Subsequent to the Merger, Historical Dow and EIDP engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products ("Internal Reorganization"). On April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow common stock to holders of DowDuPont's common stock (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”). On April 1, 2019, Historical Dow entities, which held certain assets and liabilities aligned with Historical Dow’s agriculture business and the assets and liabilities associated with its specialty products business, respectively, were transferred and conveyed to DowDuPont. On April 1, 2019 and May 1, 2019, EIDP’s materials science and specialty products entities, along with their respective assets and liabilities, were conveyed to Dow and DowDuPont, respectively. On May 2, 2019, DowDuPont conveyed Historical Dow agricultural entities to EIDP. On May 6, 2019, the Board of Directors of DowDuPont approved the distribution of all the then issued and outstanding shares of common stock of Corteva, Inc., then a wholly-owned subsidiary of DowDuPont, to DowDuPont stockholders. On May 31, 2019, DowDuPont contributed EIDP to Corteva, Inc. and on June 1, 2019, the Separation was completed. Information related to the Corteva Distribution and its effect on the company's financial statements is discussed throughout these Notes to the Consolidated Financial Statements. During the first quarter 2020, the company recorded an increase of $40 million to APIC relating to net assets recorded as transferred as part of the 2019 Internal Reorganizations that were retained. Certain reclassifications of prior year's data have been made to conform to current year's presentation. Since 2018, Argentina has been considered a hyper-inflationary economy under U.S. GAAP and therefore the U.S. Dollar (“USD”) is the functional currency for our related subsidiaries. Argentina contributes approximately 5 percent to both the company's annual Sales and Segment Operating EBITDA. We remeasure net monetary assets and translate our financial statements utilizing the official Argentine Peso (“Peso”) to USD exchange rate. The ability to draw down Peso cash balances is limited at this time due to government restrictions and market availability of U.S. Dollars. The devaluation of the Peso relative to the USD over the last several years has resulted in the recognition of exchange losses (refer to Note 6 – Supplementary Information, to the Consolidated Financial Statements). As of December 31, 2022, a further 10 percent deterioration in the official Peso to USD exchange rate would reduce the USD value of our net monetary assets and negatively impact pre-tax earnings by approximately $15 million. We will continue to assess the implications to our operations and financial reporting.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Consolidated Financial Statements include the accounts of the company and subsidiaries in which a controlling interest is maintained. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has the ability to exercise significant influence but does not have a controlling interest are accounted for under the equity method. The company is also involved with certain joint ventures accounted for under the equity method of accounting that are variable interest entities ("VIEs"). The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2022 and 2021, the maximum exposure to loss related to the nonconsolidated VIEs is not considered material to the Consolidated Financial Statements. Use of Estimates in Financial Statement Preparation The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates. Cash and Cash Equivalents Cash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest. Restricted Cash Equivalents Restricted cash equivalents primarily consist of trust assets and contributions to the escrow account for the settlement of legacy PFAS matters and the associated qualified spend. Corteva classifies restricted cash equivalents as current or noncurrent based on the nature of the restrictions, which are included in other current assets and other assets, respectively, in the Consolidated Balance Sheets. See Note 6 - Supplementary Information, to the Consolidated Financial Statements, for further information. Marketable Securities Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. Investments classified as held-to-maturity are recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments. Investments classified as debt securities that are available-for-sale are carried at estimated fair value with unrealized gains and losses recorded as a component of accumulated other comprehensive income (loss) or current period earnings if an allowance for credit losses has been established. The cost of investments sold is determined by specific identification. Fair Value Measurements Under the accounting guidance for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The company uses the following valuation techniques to measure fair value for its assets and liabilities: Level 1 – Quoted market prices in active markets for identical assets or liabilities; Level 2 – Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs); Level 3 – Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability. Foreign Currency Translation The company's worldwide operations utilize the U.S. dollar ("USD") or a related foreign 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 or foreign subsidiaries operating in a hyper-inflationary environment (USD functional currency) and 2) self-contained (related foreign functional currency). If a foreign entity does not 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-denominated asset and liability amounts are re-measured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are re-measured at historical rates. Foreign currency income and expenses are re-measured at average exchange rates in effect during each month, except for expenses related to balance sheet amounts re-measured at historical exchange rates. Exchange gains and losses arising from re-measurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur. For foreign entities where a related foreign currency is the functional currency, assets and liabilities denominated in the related foreign 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 functional currency are re-measured into the functional 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 each month. 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. Inventories The company's inventories are valued at the lower of cost or net realizable value. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or net realizable value, whichever is lower; cost is generally determined by the average cost method. As of December 31, 2022, approximately 55% and 45% of the company's inventories were accounted for under the first-in, first-out ("FIFO") and average cost methods, respectively. As of December 31, 2021, approximately 60% and 40% of the company's inventories were accounted for under the first-in, first-out ("FIFO") and average cost methods, respectively. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as seeds. See Note 10 - Inventories, to the Consolidated Financial Statements, for further information. The company establishes an obsolescence reserve for inventory based upon quality considerations and assumptions about future demand and market conditions. Property, Plant and Equipment Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. When assets are surrendered, retired, sold, or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the Consolidated Balance Sheets and included in determining gain or loss on such disposals. Goodwill and Other Intangible Assets The company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level at least annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The company performs an annual goodwill impairment test in the fourth quarter. When testing goodwill for impairment, the company has the option to first perform qualitative testing to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the company chooses not to complete a qualitative assessment for a given reporting unit or if the initial assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is required. If additional quantitative testing is required, the reporting unit's fair value is compared with its carrying amount, and an impairment charge, if any, is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, limited to the amount of goodwill associated with the reporting unit. The company determines fair values for each of the reporting units using a discounted cash flow model (a form of the income approach) or the market approach. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The company's significant assumptions in this analysis include future cash flow projections, weighted average cost of capital, the terminal growth rate, and the tax rate. Under the market approach, the company uses metrics of publicly traded companies or historically completed transactions for comparable companies. See Note 12 - Goodwill and Other Intangible Assets, to the Consolidated Financial Statements, for further information on goodwill. Indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. The company performs an impairment assessment using the relief from royalty method (a form of the income approach) using Level 3 inputs within the fair value hierarchy. The significant assumptions used in the calculation included projected revenue, the royalty rate, the discount rate, and the terminal growth rate. These significant assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows. Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 2 years to 25 years. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are no longer considered held and used, they are removed from the Consolidated Balance Sheets. 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 leases 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. See Note 13 - Leases, to the Consolidated Financial Statements, for further information. Impairment of Long-Lived Assets The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from the assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset group. The company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value. Depreciation is recognized over the remaining useful life of the assets. Derivative Instruments Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. The company utilizes derivatives to manage exposures to foreign currency exchange rates and commodity prices. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings. For derivative instruments designated as cash flow hedges, the gain (loss) is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. For derivative instruments designated as net investment hedges, the gain (loss) is reported within accumulated other comprehensive income (loss) until the subsidiary is divested. In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, the net gain or loss in accumulated other comprehensive income (loss) generally remains in accumulated other comprehensive income (loss) until the item that was hedged affects earnings. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as hedges of anticipated transactions are reclassified as for trading purposes if the anticipated transaction is no longer probable. The company included foreign currency exchange contract settlements within cash flows from operating activities, regardless of hedge accounting qualification. See Note 19 - Financial Instruments, to the Consolidated Financial Statements, for additional discussion regarding the company's objectives and strategies for derivative instruments. Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheets in accrued and other current liabilities and other noncurrent obligations at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the Consolidated Balance Sheets as accounts and notes receivable - net. Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable. Revenue Recognition The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To determine the revenue recognition for an arrangement considered to be a contract with a customer, the company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 - Revenue, to the Consolidated Financial Statements, for additional information on revenue recognition. Prepaid Royalties The company currently has certain third-party biotechnology trait license agreements, which require up-front and variable payments subject to the licensor meeting certain conditions. These payments are reflected as other current assets and other assets in the Consolidated Balance Sheets and are amortized to cost of goods sold in the Consolidated Statement of Operations as seeds containing the respective trait technology are utilized over the life of the license. The rate of royalty amortization expense recognized is based on the company’s strategic plans which include various assumptions and estimates including product portfolio, market dynamics, farmer preferences, growth rates and projected planted acres. Changes in factors and assumptions included in the strategic plans, including potential changes to the product portfolio in favor of internally developed biotechnology, could impact the rate of recognition of the relevant prepaid royalty. At December 31, 2022, the balance of prepaid royalties reflected in other current assets and other assets in the Consolidated Balance Sheets was $224 million and $101 million, respectively. The majority of the balance of prepaid royalties relates to the company’s wholly owned subsidiary, Pioneer Hi-Bred International, Inc.’s (“Pioneer”) non-exclusive license in the United States and Canada for the Monsanto Company's Genuity ® Roundup Ready 2 Yield ® glyphosate tolerance trait and Roundup Ready 2 Xtend ® glyphosate and dicamba tolerance trait for soybeans (“Roundup Ready 2 License Agreement”). Each of these licensed technologies are now trademarks of the Bayer Group, which acquired the Monsanto Company in 2018. The prepaid royalty asset relates to a series of up-front, fixed and variable royalty payments to utilize the traits in Pioneer’s soybean product mix. The company’s historical expectation was that the technology licensed under the Roundup Ready 2 License Agreement would be used as the primary herbicide tolerance trait platform in the Pioneer ® brand soybean through the term of the agreement. DAS and MS Technologies, L.L.C. jointly developed and own the Enlist E3 TM herbicide tolerance trait for soybeans which provides tolerance to 2, 4-D choline in Enlist Duo ® and Enlist One ® herbicides, as well as glyphosate and glufosinate herbicides. In connection with the validation of breeding plans and large-scale product development timelines, during the fourth quarter of 2019, the company committed to accelerate the ramp up of the Enlist E3 TM trait platform in the company’s soybean portfolio mix across all brands, including Pioneer ® brands, over the subsequent five years. During the ramp-up period, the company has began to significantly reduce the volume of products with the Roundup Ready 2 Yield ® and Roundup Ready 2 Xtend ® herbicide tolerance traits, with expected minimal use of the trait platform thereafter for the remainder of the Roundup Ready 2 License Agreement (the “Transition Plan”). The rate of royalty expense has therefore increased significantly through higher amortization of the prepaid royalty as fewer seeds containing the respective trait are expected to be utilized. In connection with the departure from these traits, beginning January 1, 2020 the company presents and discloses the non-cash accelerated prepaid royalty amortization expense as a component of restructuring and asset related charges - net, in the Consolidated Statement of Operations. The accelerated prepaid royalty amortization expense represents the difference between the rate of amortization based on the revised number of units expected to contain the Roundup Ready 2 Yield ® and Roundup Ready 2 Xtend ® trait technology and the variable cash rate per the Roundup Ready 2 License Agreement. Further changes in factors and assumptions associated with usage of the trait platform licensed under the Roundup Ready 2 License Agreement, including the Transition Plan, could further impact the rate of recognition of the prepaid royalty and Consolidated Statement of Operations presentation of the accelerated prepaid royalty amortization expense. Cost of Goods Sold Cost of goods sold primarily includes the cost of manufacture and delivery, ingredients or raw materials, direct salaries, wages and benefits and overhead, non-capitalizable costs associated with capital projects, royalties and other operational expenses. No amortization of intangibles is included within cost of goods sold. Research and Development Research and development costs are expensed as incurred. Research and development expense includes costs (primarily consisting of employee costs, materials, contract services, research agreements, and other external spend) relating to the discovery and development of new products. Selling, General and Administrative Expenses Selling, general and administrative expenses primarily include selling and marketing expenses, commissions, functional costs, and business management expenses. Litigation and Other Contingencies Accruals for legal matters and other contingencies are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs, such as outside counsel fees and expenses, are charged to expense in the period incurred. Severance Costs Severance benefits are provided to employees under the company's ongoing benefit arrangements. Severance costs are accrued when management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated. Insurance/Self-Insurance The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable. Income Taxes The company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The current portion of uncertain income tax positions is included in income taxes payable or income tax receivable, and the long-term portion is included in other noncurrent obligations or other noncurrent assets in the Consolidated Balance Sheets. Income tax related penalties are included in the provision for (benefit from) income taxes in the Consolidated Statements of Operations. Interest accrued related to unrecognized tax benefits is included within the provision for (benefit from) income taxes from continuing operations in the Consolidated Statements of Operations. Earnings per Common Share The calculation of earnings per common share is based on the weighted-average number of the company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.

This standard is effective for fiscal years beginning after December 15, 2021, and early adoption is permitted. The company adopted this guidance on January 1, 2022 and it did not have a material impact on the company’s disclosures. Accounting Guidance Issued But Not Adopted as of December 31, 2022 In September 2022, the FASB issued ASU 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. This ASU includes amendments that require a buyer in supplier finance programs to disclose key terms of the programs and related obligations, including a rollforward of such obligations. This guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the rollforward requirement, which is effective for fiscal years beginning after December 15, 2023, and early adoption is permitted. Retrospective application to all periods in which a balance sheet is presented is required, except for the rollforward requirement, which will be applied prospectively. The adoption of this guidance will result in the company being required to include certain disclosures relating to supplier financing programs and related obligations.

Revenue (Notes)

Revenue from Contract with Customer [Abstract]
Revenue	REVENUE Revenue Recognition Products Substantially all of Corteva's revenue is derived from product sales. Product sales consist of sales of Corteva's products to farmers, distributors, and manufacturers. Corteva 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. However, the company has some long-term contracts which can span multiple years. Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms are generally less than one year from invoicing. The company elected the practical expedient and does not adjust the promised amount of consideration for the effects of a significant financing component when the company expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. When the company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to or at shipment), these are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, the company elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less. The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates of variable consideration included in the transaction price primarily utilize the expected value method based on historical experience. These estimates are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, the company allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances. Licenses of Intellectual Property Corteva enters into licensing arrangements with customers under which it licenses its intellectual property. Revenue from the majority of intellectual property licenses is derived from sales-based royalties. 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. Remaining Performance Obligations Remaining performance obligations represent the transaction price allocated to unsatisfied or partially unsatisfied performance obligations. The company applies the practical expedient to disclose the transaction price allocated to remaining performance obligations for only those contracts with an original duration of one year or more. The transaction price allocated to remaining performance obligations with an original duration of more than one year related to material rights granted to customers for contract renewal options were $131 million and $123 million at December 31, 2022 and December 31, 2021, respectively. The company expects revenue to be recognized for the remaining performance obligations evenly over the period of one year to six years. Contract Balances Contract liabilities primarily reflect deferred revenue from prepayments under contracts with customers where the company receives advance payments for products to be delivered in future periods. Corteva 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 conditional rights to consideration for completed performance not yet invoiced. Accounts receivable are recorded when the right to consideration becomes unconditional. Contract Balances December 31, 2022 December 31, 2021 (In millions) Accounts and notes receivable - trade 1 $ 4,261 $ 3,561 Contract assets - current 2 $ 26 $ 24 Contract assets - noncurrent 3 $ 64 $ 58 Deferred revenue - current $ 3,388 $ 3,201 Deferred revenue - noncurrent 4 $ 107 $ 120 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 other assets in the Consolidated Balance Sheets. 4. Included in other noncurrent obligations in the Consolidated Balance Sheets. Revenue recognized during the year ended December 31, 2022, December 31, 2021, and December 31, 2020 from amounts included in deferred revenue at the beginning of the period was $3,150 million, $2,613 million, and $2,540 million, respectively.

Restructuring and Related Activities Disclosure [Text Block]	RESTRUCTURING AND ASSET RELATED CHARGES - NET 2022 Restructuring Actions In connection with the company’s shift to a global business unit model, the company assessed its business priorities and operational structure to maximize the customer experience and deliver on growth and earnings potential. As a result of this assessment, the company has committed to restructuring actions that, combined with the impact of the company’s separate announcement to withdraw from Russia (“Russia Exit”) (collectively the “2022 Restructuring Actions”), is expected to result in total net pre-tax restructuring and other charges of $350 million to $420 million comprised of $105 million to $120 million of severance and related benefit costs, $125 million to $150 million of asset related charges, $65 million to $80 million of costs related to contract terminations (including early lease terminations) and $55 million to $70 million of other charges. Cash payments related to these charges are anticipated to be $180 million to $210 million, of which approximately $90 million has been paid through December 31, 2022, and primarily relate to the payment of severance and related benefits, contract terminations and other charges. The restructuring actions associated with these charges are expected to be substantially complete in 2023. The total net pre-tax restructuring and other charges included $48 million associated with the Russia Exit for the year ended December 31, 2022. The Russia Exit net pre-tax restructuring charges consisted of $6 million of severance and related benefit costs, $6 million of asset related charges, and $26 million of costs related to contract terminations (including early lease terminations). Other pre-tax charges associated with the Russia Exit were recorded to cost of goods sold and other income (expense) – net in the Consolidated Statement of Operations, relating to inventory write-offs of $2 million and settlement costs of $8 million, respectively. Additional pre-tax charges up to $20 million associated with the Russia Exit are possible, primarily associated with the collectibility of government receivables. The company also recorded a pre-tax benefit of $3 million relating to the sale of seeds already under production in Russia when the decision to exit the country was made and that the company was contractually required to purchase, which consisted of $8 million of net sales and $5 million of cost of goods sold in the Consolidated Statement of Operations (“Russian Seed Sale”).

The years ended December 31, 2022 and 2021 include a gain of $15 million and $19 million, respectively, relating to the sale of a business in the crop protection segment. The year ended December 31, 2020 includes a loss of $(53) million and a gain of $27 million relating to the sale of the La Porte site, for which the company signed an agreement in 2020, and closed during the first quarter of 2021, and the sale of a business in Asia Pacific in the crop protection segment, respectively. 2. Includes net pre-tax exchange gains (losses) of $(110) million, $(67) million and $(82) million associated with the devaluation of the Argentine peso for the years ended December 31, 2022, 2021 and 2020, respectively. 3.

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 other income (expense) - net and the related tax impact is recorded in provision for (benefit from) income taxes on continuing operations in the Consolidated Statements of Operations.

During the year ended December 31, 2022, the company adjusted the valuation allowances recorded against the net deferred tax asset position of various legal entities, the largest of which relates to a legal entity in Brazil that resulted in a tax benefit of $(36) million. 3. Prior year amounts in "other accruals and reserves" and "other – net" have been reclassified from their previous presentation to conform to the current year's presentation. Adjustments did not impact the amount of the net deferred tax asset (liability) recorded in the Consolidated Balance Sheets. Details of the company’s operating loss and tax credit carryforwards are shown in the following table: Operating Loss and Tax Credit Carryforwards Deferred Tax Asset (In millions) 2022 2021 Operating loss carryforwards Expire within 5 years $ 127 $ 123 Expire after 5 years or indefinite expiration 158 210 Total operating loss carryforwards $ 285 $ 333 Tax credit carryforwards Expire within 5 years $ 15 $ 14 Expire after 5 years or indefinite expiration 63 117 Total tax credit carryforwards $ 78 $ 131 Total Operating Loss and Tax Credit Carryforwards $ 363 $ 464 A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows: Total Gross Unrecognized Tax Benefits For the Year Ended December 31, (In millions) 2022 2021 2020 Total unrecognized tax benefits as of beginning of period $ 377 $ 395 $ 426 Decreases related to positions taken on items from prior years (3) (7) (14) Increases related to positions taken on items from prior years 4 13 5 Increases related to positions taken in the current year 11 9 6 Settlement of uncertain tax positions with tax authorities (24) (17) (18) Decreases due to expiration of statutes of limitations (5) (16) (7) Exchange (gain) loss (3) — (3) Total unrecognized tax benefits as of end of period $ 357 $ 377 $ 395 Total unrecognized tax benefits that, if recognized, would impact the effective tax rate $ 139 $ 157 $ 156 Total amount of interest and penalties (benefits) recognized in provision for (benefit from) income taxes on continuing operations $ 1 $ 1 $ (2) Total accrual for interest and penalties associated with unrecognized tax benefits at end of period $ 13 $ 11 $ 18 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 changes to the company’s global unrecognized tax benefits could be significant; however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made. As of December 31, 2022, the company has made advance deposits of approximately $90 million to a foreign taxing authority, partially as a prerequisite to petition the court related to an open tax examination. These payments are accounted for as a prepaid asset, included in other assets in the Consolidated Balance Sheets. Tax years that remain subject to examination for the company’s major tax jurisdictions are shown below: Tax Years Subject to Examination by Major Tax Jurisdiction at December 31, 2022 Earliest Open Year Jurisdiction Argentina 2016 Brazil 2015 Canada 2012 China 2014 France 2019 India 2020 Italy 2017 Switzerland 2016 United States: Federal income tax 2012 State and local income tax 2008 Undistributed earnings of foreign subsidiaries and related companies that are deemed to be indefinitely invested amounted to $3,810 million at December 31, 2022. Distributions of profits from non-U.S. subsidiaries are subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply; these taxes are partially offset by U.S. foreign tax credits. The company is asserting indefinite reinvestment related to certain investments in foreign subsidiaries. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested profits is not feasible primarily due to our legal entity structure and the complexity of U.S. and local tax laws. For periods between the Merger on August 31, 2017, and the Corteva Distribution, Corteva and its subsidiaries were 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 was apportioned among the members of the consolidated group based on each member’s separate taxable income. Corteva, DuPont and Dow intend that to the extent federal and/or state corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or Tax Matters Agreement. See Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements for further information related to indemnifications between Corteva, DuPont and Dow. On August 16, 2022, the U.S. federal government enacted the Inflation Reduction Act of 2022 (“the Act”). The Act includes tax provisions, among other things, which implements (i) a 15 percent minimum tax on book income of certain large corporations; (ii) a one percent excise tax on net stock repurchases; and (iii) several tax incentives to promote clean energy. The company does not expect the Act to have a material impact on the company’s financial position, results of operations or cash flows.

Accounts receivable – trade and notes receivable – trade are net of allowances of $194 million and $210 million at December 31, 2022 and December 31, 2021, respectively. 2. Notes receivable – trade primarily consists of receivables for deferred payment loan programs for the sale of seed and crop protection products to customers. These loans have terms of one year or less and are primarily concentrated in North America. The company maintains a rigid pre-approval process for extending credit to customers in order to manage overall risk and exposure associated with credit losses. As of December 31, 2022 and 2021, there were no significant impairments related to current loan agreements 3. Other includes receivables in relation to indemnification assets, value added tax, general sales tax and other taxes. No individual group represents more than 5 percent of total receivables. In addition, Other includes amounts due from nonconsolidated affiliates of $148 million and $104 million as of December 31, 2022 and 2021, respectively. Accounts and notes receivable are carried at the expected amount to be collected, which approximates fair value. The company establishes the allowance for doubtful receivables using a loss-rate method where the loss rate is developed using past events, historical experience, current conditions and forecasts that affect the collectability of the financial assets. The following table summarizes changes in the allowance for doubtful receivables for the years ended December 31, 2022 and 2021 respectively: (In millions) Balance at December 31, 2020 $ 208 Net provision for credit losses 1 Write-offs charged against allowance / other 1 Balance at December 31, 2021 $ 210 Net provision for credit losses (13) Write-offs charged against allowance / other (3) Balance at December 31, 2022 $ 194 The company enters into various factoring agreements with third-party financial institutions to sell its trade receivables under both recourse and non-recourse agreements in exchange for cash proceeds. These financing arrangements result in a transfer of the company's receivables and risks to the third-party. As these transfers qualify as true sales under the applicable accounting guidance, the receivables are derecognized from the Consolidated Balance Sheets upon transfer, and the company receives a payment for the receivables from the third-party within a mutually agreed upon time period. For arrangements involving an element of recourse, which is typically provided through a guarantee of accounts in the event of customer default, the guarantee obligation is measured using market data from similar transactions and reported as a current liability in the Consolidated Balance Sheets. Trade receivables sold under these agreements were $134 million, $272 million, and $255 million for the years ended December 31, 2022, 2021 and 2020, respectively. The trade receivables sold that remained outstanding under these agreements which include an element of recourse as of December 31, 2022 and 2021 were $37 million and $166 million, respectively. The net proceeds received were included in cash provided by (used for) operating activities in the Consolidated Statements of Cash Flows. The difference between the carrying amount of the trade receivables sold and the sum of the cash received is recorded as a loss on sale of receivables in other income (expense) - net in the Consolidated Statements of Operations. The loss on sale of receivables were $19 million, $54 million, and $55 million for the years ended December 31, 2022, 2021 and 2020, respectively. See Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, for additional information on the company’s guarantees.

(In millions) Crop Protection Seed Total Balance as of December 31, 2020 $ 4,745 $ 5,524 $ 10,269 Currency translation adjustment (73) (87) (160) Other goodwill adjustments 1 — (2) (2) Balance as of December 31, 2021 $ 4,672 $ 5,435 $ 10,107 Currency translation adjustment (63) (72) (135) Other goodwill adjustments 2 9 (19) (10) Balance as of December 31, 2022 $ 4,618 $ 5,344 $ 9,962 1. Consists of the goodwill included in the sale of a business in the seed segment. 2. Consists primarily of the goodwill included in the sale of a business in the crop protection segment and the reassignment of former digital reporting unit goodwill from the seed to the crop protection segment. The company tests goodwill and other indefinite-lived intangible assets for impairment annually (during the fourth quarter), or more frequently when events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit has declined below its carrying value. Goodwill is evaluated for impairment using qualitative and / or quantitative testing procedures. The company performs goodwill impairment testing at the reporting unit level which is defined as the operating segment or one level below the operating segment. One level below the operating segment, or component, is a business in which discrete financial information is available and regularly reviewed by segment management. The company aggregates certain components into reporting units based on economic similarities. In April 2022, the company implemented a global business unit organization model ("BU Reorganization"). The BU Reorganization did not have a material impact to the company’s historical reportable segments’ financial measures and had no impact on our determination of operating segments. However, it did result in the company’s digital reporting unit being merged into the seed and crop protection reporting units with the goodwill relating to the former digital reporting unit being reassigned to the seed and crop protection reporting units using a relative fair value allocation approach. As a result of the BU Reorganization, the company determined that a triggering event had occurred during the second quarter of 2022 that required an interim impairment assessment as of April 1, 2022. The interim impairment assessment was performed for the seed, crop protection, and the former digital reporting units immediately prior to the BU Reorganization and for the seed and crop protection reporting units immediately after the BU Reorganization resulting in no goodwill impairment charges. The company performed annual quantitative testing on all of its reporting units and determined that no goodwill impairments existed in 2022 and 2021. As of December 31, 2022, accumulated impairment losses on goodwill were $4,503 million. Other Intangible Assets The gross carrying amounts and accumulated amortization of other intangible assets by major class are as follows: (In millions) December 31, 2022 December 31, 2021 Gross Accumulated Net Gross Accumulated Net Intangible assets subject to amortization (Definite-lived): Germplasm $ 6,291 $ (826) $ 5,465 $ 6,265 $ (571) $ 5,694 Customer-related 1,912 (585) 1,327 1,953 (487) 1,466 Developed technology 1,485 (830) 655 1,485 (679) 806 Trademarks/trade names 2,009 (251) 1,758 2,012 (172) 1,840 Favorable supply contracts 1 475 (396) 79 Other 2 395 (271) 124 405 (256) 149 Total other intangible assets with finite lives 12,092 (2,763) 9,329 12,595 (2,561) 10,034 Intangible assets not subject to amortization (Indefinite-lived): IPR&D 10 — 10 10 — 10 Total other intangible assets 10 — 10 10 — 10 Total $ 12,102 $ (2,763) $ 9,339 $ 12,605 $ (2,561) $ 10,044 1.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	LEASES The company has operating and finance leases for real estate, transportation, certain machinery and equipment, and information technology assets. The company’s leases have remaining lease terms of approximately 1 to 40 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. At December 31, 2022, the company has future maximum payments for residual value guarantees in operating leases of $219 million with final expirations through 2032. The company's lease agreements do not contain any material restrictive covenants.

The estimated fair value of the company's long-term borrowings, was determined using Level 2 inputs within the fair value hierarchy, as described in Note 2 - 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 long-term borrowings, not including long-term debt due within one year, was $1,172 million and $1,120 million at December 31, 2022 and 2021, respectively. Foreign Currency Loans The company enters into short-term and long-term foreign currency loans from time-to-time by accessing uncommitted revolving credit lines to fund working capital needs of foreign subsidiaries in the normal course of business ("Foreign Currency Loans"). Interest rates are variable and determined at the time of borrowing. Total unused bank credit lines on the Foreign Currency Loans at December 31, 2022 was approximately $75 million. The company's long-term Foreign Currency Loans have varying maturities through 2024.

Other than the change in maturity date, there were no material modifications to the terms of the credit facility. During May 2022, the Revolving Credit Facilities were refinanced for purposes of extending the maturity dates to 2027 and 2025 for the 5-year and 3-year Revolving Credit Facilities, respectively, lowering the facility amount of the 3-year revolving credit facility to $2 billion and transitioning the interest rate to Adjusted Term SOFR, which is Term SOFR plus 0.10 percent, plus the applicable margin. The Revolving Credit Facilities may serve as a substitute to the company's commercial paper program, and can be used from time to time, for general corporate purposes including, but not limited to, the funding of seasonal working capital needs. The Revolving Credit Facilities contain customary representations and warranties, affirmative and negative covenants and events of default that are typical for companies with similar credit ratings. Additionally, the Revolving Credit Facilities contain a financial covenant requiring that the ratio of total indebtedness to total capitalization for Corteva and its consolidated subsidiaries not exceed 0.60.

On August 5, 2021, Corteva, Inc. announced that its Board of Directors authorized a $1.5 billion share repurchase program to purchase Corteva, Inc.'s common stock, par value $0.01 per share, without an expiration date ("2021 Share Buyback Plan"). In connection with the 2021 Share Buyback Plan, the company purchased and retired 17,425,000 shares and 5,572,000 shares in the open market for a total cost of $1 billion and $250 million during the years ended December 31, 2022 and 2021, respectively. On June 26, 2019, Corteva, Inc. announced that its Board of Directors authorized a $1 billion share repurchase program to purchase Corteva, Inc.'s common stock, par value $0.01 per share, without an expiration date ("2019 Share Buyback Plan"). The company completed the 2019 Share Buyback Plan during the third quarter of 2021 and repurchased and retired 24,705,000 shares between the years ended December 31, 2019 and 2021 in the open market. The timing, price and volume of purchases in connection with the 2022 and 2021 Share Buyback Plans will be based on market conditions, relevant securities laws and other factors. Shares repurchased pursuant to Corteva's share buyback plan are immediately retired upon repurchase. Repurchased common stock is reflected as a reduction of stockholders' equity. The company's accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its retained earnings for the excess of the repurchase price over the par value. When Corteva has an accumulated deficit balance, the excess over the par value is applied to APIC. When Corteva has retained earnings, the excess is charged entirely to retained earnings. Noncontrolling Interest In June 2020, the company completed the acquisition of the remaining 46.5 percent interest in the Phytogen Seed Company, LLC joint venture from J. G. Boswell Company. As the purchase of the remaining interest did not result in a change of control, the difference between the carrying value of the noncontrolling interest and the consideration paid, net of taxes was recorded within equity. Corteva, Inc. owns 100 percent of the outstanding common shares of EIDP. However, EIDP has preferred stock outstanding to third parties which is accounted for as a noncontrolling interest in Corteva's Consolidated Balance Sheets. Each share of EIDP Preferred Stock - $4.50 Series and EIDP Preferred Stock - $3.50 Series issued and outstanding at the effective date of the Corteva Distribution remains issued and outstanding as to EIDP and was unaffected by the Corteva Distribution.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	PENSION PLANS AND OTHER POST EMPLOYMENT BENEFITS The company offers various long-term benefits to its employees. Where permitted by applicable law, the company reserves the right to change, modify or discontinue the plans. Defined Benefit Pension Plans The company has both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees and employees in a number of other countries. The principal U.S. pension plan is the largest pension plan held by Corteva. Effective January 1, 2007, a majority of new hires are not eligible to participate in the U.S. defined benefit pension plans. The company froze the pay and service amounts used to calculate the pension benefits for active employees who participate in these plans on November 30, 2018, resulting in the participants no longer accruing additional benefits. The company's funding policy is consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. Obligations under such plans are funded by depositing funds with trustees, covered by insurance contracts, or remain unfunded. The company made total contributions of $60 million, $49 million, and $62 million to its pension plans other than the principal U.S. pension plan for the years ended December 31, 2022, 2021 and 2020, respectively. Corteva expects to contribute approximately $50 million to its pension plans other than the principal U.S. pension plan in 2023. The company does not anticipate making contributions to its principal U.S pension plan in 2023. In August 2022, the company transferred approximately $1.1 billion of certain benefit obligations and associated plan assets in the principal U.S. pension plan (the “Plan”) to an insurance company through the purchase of a nonparticipating group annuity contract (“Annuity Purchase”). The company recorded a non-cash, pre-tax settlement charge of approximately $25 million in other income (expense) – net in the Consolidated Statements of Operations for the year ended December 31, 2022 and corresponding adjustment to accumulated other comprehensive income (loss) in the Consolidated Balance Sheets at December 31, 2022 due to the Annuity Purchase. The Annuity Purchase resulted in a remeasurement of the Plan as of August 31, 2022 and the company updated the weighted average discount rate used in developing the 2022 net periodic pension (credit) costs at December 31, 2021 from 2.82 percent to 4.60 percent. Due to the remeasurement, the company recorded a pre-tax actuarial gain of approximately $110 million to accumulated other comprehensive income (loss) in the Consolidated Balance Sheets at December 31, 2022. The weighted-average assumptions used to determine pension plan obligations for all pension plans are summarized in the table below: Weighted-Average Assumptions used to Determine Benefit Obligations December 31, 2022 December 31, 2021 Discount rate 5.17 % 2.82 % Rate of increase in future compensation levels 1 2.83 % 2.55 % 1. The rate of compensation increase excludes U.S. pension plans since the employees who participate in the U.S. pension plans no longer accrue additional benefits for future service and eligible compensation. The weighted-average assumptions used to determine net periodic benefit costs for all pension plans are summarized in the table below: Weighted-Average Assumptions used to Determine Net Periodic Benefit Cost For the Year Ended December 31, 2022 2021 2020 Discount rate 3.33 % 2.44 % 3.19 % Rate of increase in future compensation levels 1 2.55 % 2.54 % 2.60 % Expected long-term rate of return on plan assets 4.51 % 5.73 % 6.25 % 1. The rate of compensation increase excludes U.S. pension plans since the employees who participate in the U.S. pension plans no longer accrue additional benefits for future service and eligible compensation. Other Post Employment Benefits The company has historically provided medical, dental and life insurance benefits to certain pensioners and survivors. The majority of U.S. employees hired on or after January 1, 2007, and eligible employees under the age of 50 as of November 30, 2018, are not eligible to participate in the post-employment medical, dental and life insurance plans. Substantially all of the cost and liabilities for these retiree benefit plans are attributable to the U.S. benefit plans. The non-Medicare eligible retiree medical plan is contributory with costs shared between the company and pensioners and survivors. For Medicare eligible pensioners and survivors, Corteva provides a company-funded Health Reimbursement Arrangement ("HRA"). In December 2020, the company amended its retiree medical, dental and life insurance plans resulting in the company no longer providing retiree dental and life insurance benefits effective January 1, 2022 and Corteva’s portion of the cost of non-Medicare retiree medical coverage no longer being adjusted for cost increases, which capped the Corteva cost at the level in effect as of December 31, 2021 ("2020 OPEB Plan Amendments"). As a result of these changes, the company recorded a $939 million decrease in other post employment benefits ("OPEB") benefit obligations as of December 31, 2020 with a corresponding prior service benefit within other comprehensive income for the year ended December 31, 2020. During 2021, a substantial amount of the prior service benefit within other comprehensive income (loss) in 2020 was recognized in other income (expense) - net in the Consolidated Statement of Operations. The company also provides disability benefits to employees. Employee disability benefit plans are insured in many countries. Such plans are generally self-insured, primarily in the U.S. Obligations and expenses for self-insured plans are reflected in the change in projected benefit obligations table on page F-48. The company's OPEB plans are unfunded and the cost of the approved claims is paid from operating cash flows. Pre-tax cash requirements to cover actual net claims costs and related administrative expenses were $122 million, $198 million, and $207 million for the years ended December 31, 2022, 2021 and 2020, respectively. Changes in cash requirements reflect the net impact of per capita health care costs, demographic changes, plan amendments and changes in participant premiums, co-pays and deductibles. In 2023, the company expects to contribute approximately $135 million for its OPEB plans. The weighted-average assumptions used to determine benefit obligations for OPEB plans are summarized in the table below: Weighted-Average Assumptions used to Determine Benefit Obligations December 31, 2022 December 31, 2021 Discount rate 5.09 % 2.59 % The weighted-average assumptions used to determine net periodic benefit costs for the OPEB plans are summarized in the table below: Weighted-Average Assumptions used to Determine Net Periodic Benefit Cost For the Year Ended December 31, 2022 2021 2020 Discount rate 2.59 % 2.09 % 3.07 % As of December 31, 2022 and 2021, health care cost trend rates do not impact the benefit obligations for the OPEB plans because of the 2020 OPEB Plan Amendments. For the year ended December 31, 2020, the health care cost trend rate was assumed to be 7.0 percent for next year. Assumptions Within the U.S., the company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for the plan. The company's historical experience with the pension fund asset performance is also considered. For non-U.S. plans, assumptions reflect economic assumptions applicable to each country. In the U.S., Corteva calculates service costs and interest costs by applying individual spot rates from a yield curve (based on high-quality corporate bond yields) to the separate expected cash flows components of service cost and interest cost. Service cost and interest cost for all other plans are determined on the basis of the single equivalent discount rates derived in determining those plan obligations. The discount rates utilized to measure the pension and other post employment benefit obligations are based on the yield of high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows are individually discounted at the spot rates under the Aon AA_Above Median yield curve (based on high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. For non-U.S. benefit plans, historically the company utilized prevailing long-term high quality corporate bond indices to determine the discount rate, applicable to each country, at the measurement date. The company adopts the most recently published mortality tables and mortality improvement scale released by the Society of Actuaries in measuring its U.S. pension and other post employment benefit obligations. The effect of these adoptions is amortized into net periodic benefit cost for the years following the adoption. Summarized information on the company's pension and other post employment benefit plans is as follows: Change in Projected Benefit Obligations, Plan Assets and Funded Status Defined Benefit Pension Plans Other Post Employment Benefits (In millions) For the Year Ended December 31, For the Year Ended December 31, 2022 2021 2022 2021 Change in benefit obligations: Benefit obligation at beginning of the period $ 19,775 $ 21,682 $ 1,362 $ 1,571 Service cost 20 25 1 1 Interest cost 505 364 26 21 Plan participants' contributions 1 3 20 35 Actuarial (gain) loss (3,759) (524) (246) (33) Benefits paid (1,460) (1,490) (142) (233) Plan amendments — (15) — — Other 1 (1,080) (240) — — Effect of foreign exchange rates (20) (30) — — Benefit obligations at end of the period $ 13,982 $ 19,775 $ 1,021 $ 1,362 Change in plan assets: Fair value of plan assets at beginning of the period $ 17,827 $ 17,835 $ — $ — Actual return on plan assets (2,765) 1,685 — — Employer contributions 60 49 122 198 Plan participants' contributions 1 3 20 35 Benefits paid (1,460) (1,490) (142) (233) Other 1 (1,080) (240) — — Effect of foreign exchange rates 1 (15) — — Fair value of plan assets at end of the period $ 12,584 $ 17,827 $ — $ — Funded status U.S. plan with plan assets $ (1,050) $ (1,471) $ — $ — Non-U.S. plans with plan assets (30) (62) — — All other plans 2,3 (318) (415) (1,021) (1,362) Funded status at end of the period $ (1,398) $ (1,948) $ (1,021) $ (1,362) 1.

The strategic asset allocation for this trust fund is approved by the Pension Investment Committee. The general principles guiding U.S. pension asset investment policies are those embodied in the Employee Retirement Income Security Act of 1974 ("ERISA"). These principles include discharging Corteva's investment responsibilities for the exclusive benefit of plan participants and in accordance with the "prudent expert" standard and other ERISA rules and regulations. Corteva establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies are utilized in this process. U.S. plan assets are managed by investment professionals employed by Corteva. The remaining assets are managed by professional investment firms unrelated to the company. Corteva's pension investment professionals have discretion to manage the assets within established asset allocation ranges approved by the Pension Investment Committee. Additionally, pension trust funds are permitted to enter into certain contractual arrangements generally described as "derivatives." Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner. The weighted-average target allocation for plan assets of the company's pension plans is summarized as follows: Target Allocation for Plan Assets December 31, 2022 December 31, 2021 Asset Category U.S. equity securities 8 % 11 % Non-U.S. equity securities 7 11 Fixed income securities 64 58 Hedge funds 3 2 Private market securities 11 8 Real estate 6 5 Cash and cash equivalents 1 5 Total 100 % 100 % U.S. equity investments are primarily large-cap companies. Global equity securities include varying market capitalization levels. Global fixed income investments include corporate-issued, government-issued and asset-backed securities. Corporate debt investments include a range of credit risk and industry diversification. U.S. fixed income investments are weighted heavier than non-U.S. fixed income securities. Other investments include cash and cash equivalents, hedge funds, real estate and private market securities such as interests in private equity and venture capital partnerships. Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. For pension plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. For pension plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources. For pension plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers, fund managers, or investment contract issuers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. The tables below present the fair values of the company's pension assets by level within the fair value hierarchy, as described in Note 2 - Summary of Significant Accounting Policies: Basis of Fair Value Measurements Total Level 1 Level 2 Level 3 For the year ended December 31, 2022 (In millions) Cash and cash equivalents $ 1,348 $ 1,348 $ — $ — U.S. equity securities 1 1,200 1,195 2 3 Non-U.S. equity securities 806 806 — — Debt – government-issued 1,669 — 1,669 — Debt – corporate-issued 3,822 — 3,822 — Debt – asset-backed 695 — 695 — Hedge funds 3 — — 3 Private market securities 4 — — 4 Real estate funds 132 — — 132 Derivatives – asset position 2 — 2 — Other 62 — — 62 Subtotal $ 9,743 $ 3,349 $ 6,190 $ 204 Investments measured at net asset value Debt - government issued 35 Debt - corporate-issued 3 U.S. equity securities 20 Non-U.S. equity securities 20 Hedge funds 347 Private market securities 1,991 Real estate funds 669 Total investments measured at net asset value $ 3,085 Other items to reconcile to fair value of plan assets Pension trust receivables 2 161 Pension trust payables 3 (405) Total $ 12,584 1.

Under the Trust agreement, the consummation of the Merger was a change in control event. As a result, in November 2017, EIDP contributed $571 million to the Trust. At the Separation, Corteva transferred $39 million to DuPont. During the years ended December 31, 2022 and 2021, $58 million and $43 million, respectively, was distributed to EIDP according to the Trust agreement, and at December 31, 2022 and 2021, the balance in the Trust was $251 million and $304 million, respectively. The Trust Assets are classified as current restricted cash equivalents and included within other current assets in the Consolidated Balance Sheets. See Note 6 - Supplementary Information, to the Consolidated Financial Statements, for further information. Defined Contribution Plans Corteva provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers almost all of the U.S. full-service employees. This Plan includes a non-leveraged Employee Stock Ownership Plan ("ESOP"). Employees are not required to participate in the ESOP and those who do are free to diversify out of the ESOP. The purpose of the Plan is to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the company. The Plan is a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of Corteva may participate. Currently, Corteva contributes 100 percent of the first 6 percent of the employee's contribution election and also contributes 3 percent of each eligible employee's eligible compensation regardless of the employee's contribution.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended
	Dec. 31, 2022
Share-Based Payment Arrangement [Abstract]
Share-based Payment Arrangement [Text Block]	STOCK-BASED COMPENSATION Prior to the Corteva Distribution, Corteva employees held equity awards, including stock options, share appreciation rights (“SARs”), restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”), which were denominated in DowDuPont common stock and, in some cases, in Dow Inc. common stock, and which had originally been issued under the DuPont Equity and Incentive Plan ("EIP"), the Dow Chemical Company 2012 Stock Incentive Plan or the Dow Chemical Company 1988 Award and Option Plan. As discussed in Note 15 - Commitments and Contingent Liabilities, on April 1, 2019 the company entered into an employee matters agreement (the "EMA") with DuPont and Dow 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. With some exceptions, the EMA provides for the equitable adjustment of existing equity incentive compensation awards denominated in the common stock of DowDuPont to reflect the occurrence of the Distributions. In connection with the Separation on June 1, 2019, outstanding DowDuPont-denominated stock options, SARs, RSU and PSU awards were converted into Corteva-denominated awards under the “Employer Method,” or into both DuPont-denominated awards and Corteva-denominated awards under the “Shareholder Method,” using a formula designed to preserve the intrinsic value of the awards immediately prior to and subsequent to the Corteva Separation. The awards have the same terms and conditions under the applicable plans and award agreements prior to the Separation transactions. The conversions of equity awards did not have a material impact to the company’s consolidated financial statements. On June 1, 2019 (“Adoption Date”), in connection with the Separation, the Omnibus Incentive Plan (the "OIP") became effective. Under the OIP, the company may grant incentive awards, including stock options (both “incentive stock options” and nonqualified stock options), share appreciation rights, restricted shares, restricted stock units, other share-based awards and cash awards, to its and its subsidiaries’ eligible employees, non-employee directors, independent contractors and consultants following the Separation until the tenth anniversary of the Adoption Date, subject to an aggregate limit and annual individual limits. Under the OIP, the maximum number of shares reserved for the grant or settlement of awards is 20 million shares, excluding shares underlying certain exempt awards, such as the awards converted to Corteva-denominated awards pursuant to the Separation. At December 31, 2022, approximately 11 million shares were authorized for future grants under the OIP. The company generally satisfies stock option exercises and the vesting of RSUs and PSUs with newly issued shares of Corteva common stock, although RSU awards granted under Historical Dow plans in certain countries are settled in cash. The compensation committee determines the long-term incentive mix, including stock options, RSUs and PSUs and may authorize new grants annually. The company estimates expected forfeitures. The total stock-based compensation cost included in income (loss) from continuing operations before income taxes within the Consolidated Statement of Operations was $55 million, $79 million, and $73 million for the years ended December 31, 2022, 2021 and 2020, respectively. The income tax benefits related to stock-based compensation arrangements were $(10) million, $(15) million, and $(15) million for the years ended December 31, 2022, 2021 and 2020, respectively. Stock Options The exercise price of shares subject to option is equal to the market price of the company's common stock on the date of grant. All options vest serially over a period of three years. Stock option awards granted under the OIP between June 2019 and 2022 expire 10 years after the grant date. Stock option awards granted under the EIP (previous plan) between 2016 and May 2019 expire 10 years after the grant date. Stock option awards granted under the Historical Dow plans subsequent to 2013 expire 10 years after the grant date. To measure the fair value of the awards on the date of grant, the company used the Black-Scholes option pricing model and the assumptions set forth in the below table. The weighted-average grant-date fair value of options granted for the years ended December 31, 2022, 2021 and 2020 was $14.12, $11.77 and $6.06, respectively. Weighted-Average Assumptions For the Year ended December 31, 2022 2021 2020 Dividend yield 1.09 % 1.14 % 1.67 % Expected volatility 28.95 % 29.44 % 23.14 % Risk-free interest rate 1.9 % 1.0 % 1.3 % Expected life of stock options granted during period (years) 6.0 6.0 6.0 The company determined the dividend yield by dividing the annualized dividend on Corteva’s Common Stock by the option exercise price. A historical daily measurement of volatility is determined based on the expected life of the option granted. For the years ended December 31, 2022, 2021 and 2020, the measurement of volatility is based on the average volatility of eight of Corteva's peer companies. Corteva's peer volatility is based on the historical volatility of each business respectively. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by utilizing the simplified method for estimating expected term. The following table summarizes stock option activity for year ended December 31, 2022: Stock Options For the Year Ended December 31, 2022 Number of Shares Weighted Average Exercise Price (per share) Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value Outstanding at January 1, 2022 6,423 $ 36.65 5.69 $ 68,219 Granted 410 51.16 Exercised (2,099) 34.01 Forfeited/Expired (509) 38.78 Outstanding at December 31, 2022 4,225 $ 39.13 5.37 $ 82,917 Exercisable at December 31, 2022 3,330 $ 37.66 4.75 $ 70,354 The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between the closing stock price on the last trading day of the period ended December 31, 2022 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at period end. The total intrinsic value of options exercised for the years ended December 31, 2022, 2021 and 2020 were $43 million, $43 million, and $21 million, respectively. The company recognized tax benefits from options exercised for the years ended December 31, 2022, 2021 and 2020 of $(8) million, $(8) million and $(4) million, respectively. As of December 31, 2022, $5 million of total unrecognized pre-tax compensation expense related to nonvested stock options is expected to be recognized over a weighted-average period of about 1.11 years. Restricted Stock Units and Performance Share Units RSUs granted serially vest over 3 years. Upon vesting, these RSUs convert one-for-one to Corteva Common Stock. A retirement-eligible employee retains any granted awards upon retirement for one year provided the employee has rendered at least six months of service following the grant date. Additional RSUs are also granted periodically to key senior management employees. These RSUs generally vest over periods ranging from 3 years to 5 years. The fair value of all stock-settled RSUs is based upon the market price of the underlying common stock as of the grant date. The company grants PSUs to senior leadership. In 2022, there were 313,818 PSUs granted. Vesting for PSUs granted in 2022 is partially based on the realization of the Company’s improvement of its Return on Net Assets (“RONA”) and Operating Earnings Per Share ("EPS") during the Performance Period.Vesting for PSUs granted in 2021 and 2020 is partially based on the realization of the Company’s improvement of its Return on Invested Capital (“ROIC”) and Operating EPS during the Performance Period. Performance and payouts are determined independently for each metric. The actual award, delivered in Corteva Common Stock, can range from zero percent to 200 percent of the original grant. The weighted-average grant date fair value of the PSUs granted in 2022 of $51.21 was based upon the market price of the underlying common stock as of the grant date.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments Disclosure [Text Block]	FINANCIAL INSTRUMENTS At December 31, 2022 and 2021, the company had $2,296 million and $3,400 million, respectively, of held-to-maturity securities (primarily time deposits and money market funds) classified as cash equivalents in the Consolidated Balance Sheets, as these securities had maturities of three months or less at the time of purchase; $124 million and $86 million at December 31, 2022 and 2021, respectively, of held-to-maturity securities (primarily time deposits and foreign government bonds) classified as marketable securities in the Consolidated Balance Sheets, as these securities had maturities of more than three months to less than one year at the time of purchase; and $27 million at December 31, 2022 of held-to-maturity securities (primarily foreign government bonds) classified as marketable securities and included in other assets in the Consolidated Balance Sheets, as these securities had maturities of more 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. The company’s held-to-maturity securities relating to investments in foreign government bonds at December 31, 2022 and available-for-sale securities sold during the year ended December 31, 2021 are discussed further in the “Debt Securities” section. 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 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, and multinational grain exporters. The company is exposed to credit losses 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) December 31, 2022 December 31, 2021 Derivatives designated as hedging instruments: Foreign currency contracts $ 953 $ 1,252 Commodity contracts $ 1,167 $ 845 Derivatives not designated as hedging instruments: Foreign currency contracts $ 430 $ 103 Commodity contracts $ 9 $ 4 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 and to mitigate the exposure of certain investments in foreign subsidiaries against changes in the Euro/USD exchange rate. 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, investments and cash flows. The company uses foreign currency 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 forecasted transactions as well as the translation of foreign currency-denominated earnings. The company also uses commodity contracts to offset risks associated with foreign currency devaluation in certain countries. Commodity Price Risk Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as corn and soybeans. 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 years. 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 probable of not occurring. The following table summarizes the after-tax effect of commodity contract cash flow hedges on accumulated other comprehensive income (loss): For the Year Ended December 31, (In millions) 2022 2021 2020 Beginning balance $ 47 $ (16) $ 2 Additions and revaluations of derivatives designated as cash flow hedges 102 92 (44) Clearance of hedge results to earnings (94) (29) 26 Ending balance $ 55 $ 47 $ (16) At December 31, 2022, an after-tax net gain of $42 million is expected to be reclassified from accumulated other comprehensive income (loss) into earnings over the next twelve months. Foreign Currency Contracts The company enters into forward contracts to hedge the foreign currency risk associated with forecasted transactions within certain foreign subsidiaries. While each risk management program has a different time maturity period, most programs currently do not extend beyond the next two years. 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 foreign currency cash flow hedges on accumulated other comprehensive income (loss): (In millions) For the Year Ended December 31, 2022 2021 2020 Beginning balance $ 32 $ (17) $ — Additions and revaluations of derivatives designated as cash flow hedges (61) 24 (3) Clearance of hedges results to earnings 39 25 (14) Ending balance $ 10 $ 32 $ (17) At December 31, 2022, an after-tax net gain of $10 million is expected to be reclassified from accumulated other comprehensive income (loss) into earnings over the next twelve months. Derivatives Designated as Net Investment Hedges Foreign Currency Contracts The company has designated €450 million of forward contracts to exchange EUR as net investment hedges. The purpose of these forward contracts is to mitigate FX exposure related to a portion of the company’s Euro net investments in certain foreign subsidiaries against changes in Euro/USD exchange rates. These hedges will expire and be settled in 2023. The company elected to apply the spot method in testing for effectiveness of the hedging relationship. Derivatives not Designated in Hedging Relationships Foreign Currency Contracts The company uses foreign 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 the translation of certain foreign currency-denominated earnings so that gains and losses on the contracts offset changes in the USD value of the related foreign currency-denominated earnings over the relevant aggregate period. 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 and soybeans. The company uses forward agreements, with durations less than one year, to buy and sell USD priced commodities in order to reduce its exposure to currency devaluation for a portion of its local currency cash balances. Counterparties to the forward sales agreements are multinational grain exporters and subject to the company’s financial risk management procedures. 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 Consolidated Balance Sheets. The presentation of the company's derivative assets and liabilities is as follows: December 31, 2022 (In millions) Balance Sheet Location Gross Counterparty and Cash Collateral Netting 1 Net Amounts Included in the Consolidated Balance Sheet Asset derivatives: Derivatives designated as hedging instruments: Foreign currency contracts Other current assets $ 41 $ — $ 41 Commodity Contracts Other current assets 4 — 4 Derivatives not designated as hedging instruments: Foreign currency contracts Other current assets 51 (40) 11 Total asset derivatives $ 96 $ (40) $ 56 Liability derivatives: Derivatives designated as hedging instruments: Foreign currency contracts Accrued and other current liabilities $ 9 $ — $ 9 Commodity Contracts Accrued and other current liabilities 3 — 3 Derivatives not designated as hedging instruments: Foreign currency contracts Accrued and other current liabilities 58 (40) 18 Total liability derivatives $ 70 $ (40) $ 30 December 31, 2021 (In millions) Balance Sheet Location Gross Counterparty and Cash Collateral Netting 1 Net Amounts Included in the Consolidated Balance Sheet Asset derivatives: Derivatives designated as hedging instruments: Foreign currency contracts Other current assets $ 37 $ — $ 37 Derivatives not designated as hedging instruments: Foreign currency contracts Other current assets 31 (20) 11 Commodity contracts Other current assets 3 — 3 Total asset derivatives $ 71 $ (20) $ 51 Liability derivatives: Derivatives designated as hedging instruments: Foreign currency contracts Accrued and other current liabilities $ 1 $ — $ 1 Derivatives not designated as hedging instruments: Foreign currency contracts Accrued and other current liabilities 23 (20) 3 Commodity contracts Accrued and other current liabilities 2 — 2 Total liability derivatives $ 26 $ (20) $ 6 1.

The company's debt securities at December 31, 2022 consists of foreign government bonds, which are classified as held-to-maturity. During 2021, the company sold its U.S. treasuries classified as available-for-sale securities. The estimated fair value of the available-for-sale securities that were sold in 2021 was determined using Level 1 inputs within the fair value hierarchy. Level 1 measurements were based on quoted market prices in active markets for identical assets and liabilities. The available-for-sale securities that were sold in 2021 were held by certain foreign subsidiaries in which the USD is not the functional currency. The fluctuations in foreign exchange were initially recorded in accumulated other comprehensive income (loss) within the Consolidated Statements of Equity and subsequently reclassified to earnings when sold. The gains and losses on these securities offset a portion of the foreign exchange fluctuations in earnings for the company.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	FAIR VALUE MEASUREMENTS The following tables summarize the basis used to measure certain assets and liabilities at fair value on a recurring basis: Significant Other Observable Inputs December 31, 2022 December 31, 2021 (In millions) Level 1 Level 2 Level 1 Level 2 Assets at fair value: Marketable securities $ — $ 124 $ — $ 86 Derivatives relating to: 1 Foreign currency — 92 — 68 Commodity Contracts — 4 — — Equity securities 2 — — 48 — Total assets at fair value $ — $ 220 $ 48 $ 154 Liabilities at fair value: Derivatives relating to: 1 Foreign currency — 67 — 24 Commodity contracts — 3 — — Total liabilities at fair value $ — $ 70 $ — $ 24 1. See Note 19 - Financial Instruments, to the Consolidated Financial Statements, for the classification of derivatives in the Consolidated Balance Sheets. 2. The company's equity securities are included in other assets in the Consolidated Balance Sheets. For assets and liabilities classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. For assets and liabilities classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability, or by using observable market data points of similar, more liquid securities to imply the price. For time deposits classified as held-to-maturity investments and reported at amortized cost, fair value is based on an observable interest rate for similar securities. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates and implied volatilities obtained from various market sources. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. See Note 19 - Financial Instruments, to the Consolidated Financial Statements, for further information on the types of instruments used by the company for risk management. There were no transfers between Levels 1 and 2 during the years ended December 31, 2022 and 2021. For assets classified as Level 3 measurements, the fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity. The fair value of the company’s interests held in trade receivable conduits is determined by calculating the expected amount of cash to be received using the key input of anticipated credit losses in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rate and prepayments are not factors in determining the fair value of the interests.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	SEGMENT INFORMATION Corteva’s reportable segments reflects the manner in which its chief operating decision maker ("CODM") allocates resources and assesses performance, which is at the operating segment level (seed and crop protection). For purposes of allocating resources to the segments and assessing segment performance, segment operating EBITDA is the primary measure used by Corteva’s CODM. The company defines segment operating EBITDA as earnings (loss) (i.e., income (loss) from continuing operations before income taxes) before interest, depreciation, amortization, corporate expenses, non-operating (benefits) costs, foreign exchange gains (losses), and net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting, excluding the impact of significant items. Effective January 1, 2021, on a prospective basis, the company excludes from segment operating EBITDA net unrealized gain or loss from mark-to- market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting. Non-operating (benefits) costs consists of non-operating pension and other post-employment benefit (OPEB) credits (costs), tax indemnification adjustments, environmental remediation and legal costs associated with legacy EIDP businesses and sites, and the 2021 officer indemnification payment. Tax indemnification adjustments relate to changes in indemnification balances, as a result of the application of the terms of the Tax Matters Agreement, between Corteva and Dow and/or DuPont that are recorded by the company as pre-tax income or expense. Net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting represents the non-cash net gain (loss) from changes in fair value of certain undesignated foreign currency derivative contracts. Upon settlement, which is within the same calendar year of execution of the contract, the realized gain (loss) from the changes in fair value of the non-qualified foreign currency derivative contracts will be reported in the respective segment results to reflect the economic effects of the foreign currency derivative contracts without the resulting unrealized mark to fair value volatility. Corporate Profile The company conducts its global operations through the following reportable segments: Seed The company’s seed segment is a global leader in developing and supplying advanced germplasm and traits that produce optimum yield for farms around the world. The segment is a leader in many of the company’s key seed markets, including North America corn and soybeans, Europe corn and sunflower, as well as Brazil, India, South Africa and Argentina corn. The segment offers trait technologies that improve resistance to weather, disease, insects and enhance food and nutritional characteristics, herbicides used to control weeds, and digital solutions that assist farmer decision-making to help maximize yield and profitability. Crop Protection The crop protection segment serves the global agricultural input industry with products that protect against weeds, insects and other pests, and disease, and that improve overall crop health both above and below ground via nitrogen management and seed-applied technologies. The segment offers crop protection solutions and digital solutions that provide farmers the tools they need to improve productivity and profitability, and help keep fields free of weeds, insects and diseases. The segment is a leader in global herbicides, insecticides, nitrogen stabilizers and pasture and range management herbicides.

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BACKGROUND AND BASIS OF PRESENTATION Corteva, Inc. is a leading global provider of seed and crop protection solutions focused on the agriculture industry. The company intends to leverage its rich heritage of scientific achievement to advance its robust innovation pipeline and continue to shape the future of responsible agriculture. The company's broad portfolio of agriculture solutions fuels farmer productivity around the globe. Corteva has two reportable segments: seed and crop protection. See Note 22 - Segment Information, to the Consolidated Financial Statements, for additional information on the company's reportable segments. Throughout these financial statements, except as otherwise noted by the context, the terms "Corteva" or "company" used herein mean Corteva, Inc. and its consolidated subsidiaries (including EIDP) and the term “EIDP” used herein means EIDP, Inc. (formerly known as E. I. du Pont de Nemours and Company) and its consolidated subsidiaries or EIDP, Inc. excluding its consolidated subsidiaries, as the context may indicate. Principles of Consolidation and Basis of Presentation On June 1, 2019, Corteva, Inc. became an independent, publicly traded company through the completed separation (the “Separation”) of the agriculture business of DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.) (“DowDuPont” or “DuPont”). The separation was effectuated through a pro rata distribution (the “Corteva Distribution”) of all of the then-issued and outstanding shares of common stock of Corteva, Inc. Subsequent to the Merger, Historical Dow and EIDP engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products ("Internal Reorganization"). On April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow common stock to holders of DowDuPont's common stock (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”). On April 1, 2019, Historical Dow entities, which held certain assets and liabilities aligned with Historical Dow’s agriculture business and the assets and liabilities associated with its specialty products business, respectively, were transferred and conveyed to DowDuPont. On April 1, 2019 and May 1, 2019, EIDP’s materials science and specialty products entities, along with their respective assets and liabilities, were conveyed to Dow and DowDuPont, respectively. On May 2, 2019, DowDuPont conveyed Historical Dow agricultural entities to EIDP. On May 6, 2019, the Board of Directors of DowDuPont approved the distribution of all the then issued and outstanding shares of common stock of Corteva, Inc., then a wholly-owned subsidiary of DowDuPont, to DowDuPont stockholders. On May 31, 2019, DowDuPont contributed EIDP to Corteva, Inc. and on June 1, 2019, the Separation was completed. Information related to the Corteva Distribution and its effect on the company's financial statements is discussed throughout these Notes to the Consolidated Financial Statements. During the first quarter 2020, the company recorded an increase of $40 million to APIC relating to net assets recorded as transferred as part of the 2019 Internal Reorganizations that were retained. Certain reclassifications of prior year's data have been made to conform to current year's presentation. Since 2018, Argentina has been considered a hyper-inflationary economy under U.S. GAAP and therefore the U.S. Dollar (“USD”) is the functional currency for our related subsidiaries. Argentina contributes approximately 5 percent to both the company's annual Sales and Segment Operating EBITDA. We remeasure net monetary assets and translate our financial statements utilizing the official Argentine Peso (“Peso”) to USD exchange rate. The ability to draw down Peso cash balances is limited at this time due to government restrictions and market availability of U.S. Dollars. The devaluation of the Peso relative to the USD over the last several years has resulted in the recognition of exchange losses (refer to Note 6 – Supplementary Information, to the Consolidated Financial Statements). As of December 31, 2022, a further 10 percent deterioration in the official Peso to USD exchange rate would reduce the USD value of our net monetary assets and negatively impact pre-tax earnings by approximately $15 million. We will continue to assess the implications to our operations and financial reporting.

Includes a tax benefit of $(36) million for the year ended December 31, 2022, relating to the release of a valuation allowance recorded against the net deferred tax asset position of a legal entity in Brazil.

Primarily related to the realization of recorded tax benefits on tax loss and credit carryforwards from operations in the United States and Spain. 2. During the year ended December 31, 2022, the company adjusted the valuation allowances recorded against the net deferred tax asset position of various legal entities, the largest of which relates to a legal entity in Brazil that resulted in a tax benefit of $(36) million. 3. Prior year amounts in "other accruals and reserves" and "other – net" have been reclassified from their previous presentation to conform to the current year's presentation. Adjustments did not impact the amount of the net deferred tax asset (liability) recorded in the Consolidated Balance Sheets. Details of the company’s operating loss and tax credit carryforwards are shown in the following table: Operating Loss and Tax Credit Carryforwards Deferred Tax Asset (In millions) 2022 2021 Operating loss carryforwards Expire within 5 years $ 127 $ 123 Expire after 5 years or indefinite expiration 158 210 Total operating loss carryforwards $ 285 $ 333 Tax credit carryforwards Expire within 5 years $ 15 $ 14 Expire after 5 years or indefinite expiration 63 117 Total tax credit carryforwards $ 78 $ 131 Total Operating Loss and Tax Credit Carryforwards $ 363 $ 464 A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows: Total Gross Unrecognized Tax Benefits For the Year Ended December 31, (In millions) 2022 2021 2020 Total unrecognized tax benefits as of beginning of period $ 377 $ 395 $ 426 Decreases related to positions taken on items from prior years (3) (7) (14) Increases related to positions taken on items from prior years 4 13 5 Increases related to positions taken in the current year 11 9 6 Settlement of uncertain tax positions with tax authorities (24) (17) (18) Decreases due to expiration of statutes of limitations (5) (16) (7) Exchange (gain) loss (3) — (3) Total unrecognized tax benefits as of end of period $ 357 $ 377 $ 395 Total unrecognized tax benefits that, if recognized, would impact the effective tax rate $ 139 $ 157 $ 156 Total amount of interest and penalties (benefits) recognized in provision for (benefit from) income taxes on continuing operations $ 1 $ 1 $ (2) Total accrual for interest and penalties associated with unrecognized tax benefits at end of period $ 13 $ 11 $ 18 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 changes to the company’s global unrecognized tax benefits could be significant; however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made. As of December 31, 2022, the company has made advance deposits of approximately $90 million to a foreign taxing authority, partially as a prerequisite to petition the court related to an open tax examination. These payments are accounted for as a prepaid asset, included in other assets in the Consolidated Balance Sheets. Tax years that remain subject to examination for the company’s major tax jurisdictions are shown below: Tax Years Subject to Examination by Major Tax Jurisdiction at December 31, 2022 Earliest Open Year Jurisdiction Argentina 2016 Brazil 2015 Canada 2012 China 2014 France 2019 India 2020 Italy 2017 Switzerland 2016 United States: Federal income tax 2012 State and local income tax 2008 Undistributed earnings of foreign subsidiaries and related companies that are deemed to be indefinitely invested amounted to $3,810 million at December 31, 2022. Distributions of profits from non-U.S. subsidiaries are subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply; these taxes are partially offset by U.S. foreign tax credits. The company is asserting indefinite reinvestment related to certain investments in foreign subsidiaries. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested profits is not feasible primarily due to our legal entity structure and the complexity of U.S. and local tax laws. For periods between the Merger on August 31, 2017, and the Corteva Distribution, Corteva and its subsidiaries were 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 was apportioned among the members of the consolidated group based on each member’s separate taxable income. Corteva, DuPont and Dow intend that to the extent federal and/or state corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or Tax Matters Agreement. See Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements for further information related to indemnifications between Corteva, DuPont and Dow. On August 16, 2022, the U.S. federal government enacted the Inflation Reduction Act of 2022 (“the Act”). The Act includes tax provisions, among other things, which implements (i) a 15 percent minimum tax on book income of certain large corporations; (ii) a one percent excise tax on net stock repurchases; and (iii) several tax incentives to promote clean energy. The company does not expect the Act to have a material impact on the company’s financial position, results of operations or cash flows.

Segment Reporting Information [Line Items]
Segment Reporting Disclosure [Text Block]	SEGMENT INFORMATION Corteva’s reportable segments reflects the manner in which its chief operating decision maker ("CODM") allocates resources and assesses performance, which is at the operating segment level (seed and crop protection). For purposes of allocating resources to the segments and assessing segment performance, segment operating EBITDA is the primary measure used by Corteva’s CODM. The company defines segment operating EBITDA as earnings (loss) (i.e., income (loss) from continuing operations before income taxes) before interest, depreciation, amortization, corporate expenses, non-operating (benefits) costs, foreign exchange gains (losses), and net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting, excluding the impact of significant items. Effective January 1, 2021, on a prospective basis, the company excludes from segment operating EBITDA net unrealized gain or loss from mark-to- market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting. Non-operating (benefits) costs consists of non-operating pension and other post-employment benefit (OPEB) credits (costs), tax indemnification adjustments, environmental remediation and legal costs associated with legacy EIDP businesses and sites, and the 2021 officer indemnification payment. Tax indemnification adjustments relate to changes in indemnification balances, as a result of the application of the terms of the Tax Matters Agreement, between Corteva and Dow and/or DuPont that are recorded by the company as pre-tax income or expense. Net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting represents the non-cash net gain (loss) from changes in fair value of certain undesignated foreign currency derivative contracts. Upon settlement, which is within the same calendar year of execution of the contract, the realized gain (loss) from the changes in fair value of the non-qualified foreign currency derivative contracts will be reported in the respective segment results to reflect the economic effects of the foreign currency derivative contracts without the resulting unrealized mark to fair value volatility. Corporate Profile The company conducts its global operations through the following reportable segments: Seed The company’s seed segment is a global leader in developing and supplying advanced germplasm and traits that produce optimum yield for farms around the world. The segment is a leader in many of the company’s key seed markets, including North America corn and soybeans, Europe corn and sunflower, as well as Brazil, India, South Africa and Argentina corn. The segment offers trait technologies that improve resistance to weather, disease, insects and enhance food and nutritional characteristics, herbicides used to control weeds, and digital solutions that assist farmer decision-making to help maximize yield and profitability. Crop Protection The crop protection segment serves the global agricultural input industry with products that protect against weeds, insects and other pests, and disease, and that improve overall crop health both above and below ground via nitrogen management and seed-applied technologies. The segment offers crop protection solutions and digital solutions that provide farmers the tools they need to improve productivity and profitability, and help keep fields free of weeds, insects and diseases. The segment is a leader in global herbicides, insecticides, nitrogen stabilizers and pasture and range management herbicides.

Intended Business Separations [Policy Text Block]	Subsequent to the Merger, Historical Dow and EIDP engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products ("Internal Reorganization"). On April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow common stock to holders of DowDuPont's common stock (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”). On April 1, 2019, Historical Dow entities, which held certain assets and liabilities aligned with Historical Dow’s agriculture business and the assets and liabilities associated with its specialty products business, respectively, were transferred and conveyed to DowDuPont. On April 1, 2019 and May 1, 2019, EIDP’s materials science and specialty products entities, along with their respective assets and liabilities, were conveyed to Dow and DowDuPont, respectively. On May 2, 2019, DowDuPont conveyed Historical Dow agricultural entities to EIDP.

Discontinued Operations, Policy [Policy Text Block]	Since 2018, Argentina has been considered a hyper-inflationary economy under U.S. GAAP and therefore the U.S. Dollar (“USD”) is the functional currency for our related subsidiaries. Argentina contributes approximately 5 percent to both the company's annual Sales and Segment Operating EBITDA. We remeasure net monetary assets and translate our financial statements utilizing the official Argentine Peso (“Peso”) to USD exchange rate. The ability to draw down Peso cash balances is limited at this time due to government restrictions and market availability of U.S. Dollars. The devaluation of the Peso relative to the USD over the last several years has resulted in the recognition of exchange losses (refer to Note 6 – Supplementary Information, to the Consolidated Financial Statements). As of December 31, 2022, a further 10 percent deterioration in the official Peso to USD exchange rate would reduce the USD value of our net monetary assets and negatively impact pre-tax earnings by approximately $15 million. We will continue to assess the implications to our operations and financial reporting.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Consolidation	The Consolidated Financial Statements include the accounts of the company and subsidiaries in which a controlling interest is maintained. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has the ability to exercise significant influence but does not have a controlling interest are accounted for under the equity method. The company is also involved with certain joint ventures accounted for under the equity method of accounting that are variable interest entities ("VIEs"). The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2022 and 2021, the maximum exposure to loss related to the nonconsolidated VIEs is not considered material to the Consolidated Financial Statements.
Use of Estimates	Use of Estimates in Financial Statement PreparationThe preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest.
Restricted Cash	Restricted Cash Equivalents Restricted cash equivalents primarily consist of trust assets and contributions to the escrow account for the settlement of legacy PFAS matters and the associated qualified spend. Corteva classifies restricted cash equivalents as current or noncurrent based on the nature of the restrictions, which are included in other current assets and other assets, respectively, in the Consolidated Balance Sheets. See Note 6 - Supplementary Information, to the Consolidated Financial Statements, for further information.
Marketable Securities	Marketable Securities Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. Investments classified as held-to-maturity are recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments. Investments classified as debt securities that are available-for-sale are carried at estimated fair value with unrealized gains and losses recorded as a component of accumulated other comprehensive income (loss) or current period earnings if an allowance for credit losses has been established. The cost of investments sold is determined by specific identification.
Fair Value Measurements	Fair Value Measurements Under the accounting guidance for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The company uses the following valuation techniques to measure fair value for its assets and liabilities: Level 1 – Quoted market prices in active markets for identical assets or liabilities; Level 2 – Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs); Level 3 – Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.
Foreign Currency Translation	Foreign Currency Translation The company's worldwide operations utilize the U.S. dollar ("USD") or a related foreign 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 or foreign subsidiaries operating in a hyper-inflationary environment (USD functional currency) and 2) self-contained (related foreign functional currency). If a foreign entity does not 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-denominated asset and liability amounts are re-measured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are re-measured at historical rates. Foreign currency income and expenses are re-measured at average exchange rates in effect during each month, except for expenses related to balance sheet amounts re-measured at historical exchange rates. Exchange gains and losses arising from re-measurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur. For foreign entities where a related foreign currency is the functional currency, assets and liabilities denominated in the related foreign 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 functional currency are re-measured into the functional 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 each month. 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.
Inventories	Inventories The company's inventories are valued at the lower of cost or net realizable value. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or net realizable value, whichever is lower; cost is generally determined by the average cost method. As of December 31, 2022, approximately 55% and 45% of the company's inventories were accounted for under the first-in, first-out ("FIFO") and average cost methods, respectively. As of December 31, 2021, approximately 60% and 40% of the company's inventories were accounted for under the first-in, first-out ("FIFO") and average cost methods, respectively. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as seeds. See Note 10 - Inventories, to the Consolidated Financial Statements, for further information. The company establishes an obsolescence reserve for inventory based upon quality considerations and assumptions about future demand and market conditions.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. When assets are surrendered, retired, sold, or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the Consolidated Balance Sheets and included in determining gain or loss on such disposals.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level at least annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The company performs an annual goodwill impairment test in the fourth quarter. When testing goodwill for impairment, the company has the option to first perform qualitative testing to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the company chooses not to complete a qualitative assessment for a given reporting unit or if the initial assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is required. If additional quantitative testing is required, the reporting unit's fair value is compared with its carrying amount, and an impairment charge, if any, is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, limited to the amount of goodwill associated with the reporting unit. The company determines fair values for each of the reporting units using a discounted cash flow model (a form of the income approach) or the market approach. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The company's significant assumptions in this analysis include future cash flow projections, weighted average cost of capital, the terminal growth rate, and the tax rate. Under the market approach, the company uses metrics of publicly traded companies or historically completed transactions for comparable companies. See Note 12 - Goodwill and Other Intangible Assets, to the Consolidated Financial Statements, for further information on goodwill. Indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. The company performs an impairment assessment using the relief from royalty method (a form of the income approach) using Level 3 inputs within the fair value hierarchy. The significant assumptions used in the calculation included projected revenue, the royalty rate, the discount rate, and the terminal growth rate. These significant assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows. Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 2 years to 25 years. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are no longer considered held and used, they are removed from the Consolidated Balance Sheets.
Leases	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.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from the assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset group. The company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value. Depreciation is recognized over the remaining useful life of the assets.
Derivative Instruments	Derivative Instruments Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. The company utilizes derivatives to manage exposures to foreign currency exchange rates and commodity prices. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings. For derivative instruments designated as cash flow hedges, the gain (loss) is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. For derivative instruments designated as net investment hedges, the gain (loss) is reported within accumulated other comprehensive income (loss) until the subsidiary is divested. In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, the net gain or loss in accumulated other comprehensive income (loss) generally remains in accumulated other comprehensive income (loss) until the item that was hedged affects earnings. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as hedges of anticipated transactions are reclassified as for trading purposes if the anticipated transaction is no longer probable. The company included foreign currency exchange contract settlements within cash flows from operating activities, regardless of hedge accounting qualification. See Note 19 - Financial Instruments, to the Consolidated Financial Statements, for additional discussion regarding the company's objectives and strategies for derivative instruments.
Environmental Matters	Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheets in accrued and other current liabilities and other noncurrent obligations at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the Consolidated Balance Sheets as accounts and notes receivable - net. Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.
Revenue Recognition	Revenue Recognition The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To determine the revenue recognition for an arrangement considered to be a contract with a customer, the company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 - Revenue, to the Consolidated Financial Statements, for additional information on revenue recognition.
Royalty Expense	Prepaid Royalties The company currently has certain third-party biotechnology trait license agreements, which require up-front and variable payments subject to the licensor meeting certain conditions. These payments are reflected as other current assets and other assets in the Consolidated Balance Sheets and are amortized to cost of goods sold in the Consolidated Statement of Operations as seeds containing the respective trait technology are utilized over the life of the license. The rate of royalty amortization expense recognized is based on the company’s strategic plans which include various assumptions and estimates including product portfolio, market dynamics, farmer preferences, growth rates and projected planted acres. Changes in factors and assumptions included in the strategic plans, including potential changes to the product portfolio in favor of internally developed biotechnology, could impact the rate of recognition of the relevant prepaid royalty. At December 31, 2022, the balance of prepaid royalties reflected in other current assets and other assets in the Consolidated Balance Sheets was $224 million and $101 million, respectively. The majority of the balance of prepaid royalties relates to the company’s wholly owned subsidiary, Pioneer Hi-Bred International, Inc.’s (“Pioneer”) non-exclusive license in the United States and Canada for the Monsanto Company's Genuity ® Roundup Ready 2 Yield ® glyphosate tolerance trait and Roundup Ready 2 Xtend ® glyphosate and dicamba tolerance trait for soybeans (“Roundup Ready 2 License Agreement”). Each of these licensed technologies are now trademarks of the Bayer Group, which acquired the Monsanto Company in 2018. The prepaid royalty asset relates to a series of up-front, fixed and variable royalty payments to utilize the traits in Pioneer’s soybean product mix. The company’s historical expectation was that the technology licensed under the Roundup Ready 2 License Agreement would be used as the primary herbicide tolerance trait platform in the Pioneer ® brand soybean through the term of the agreement. DAS and MS Technologies, L.L.C. jointly developed and own the Enlist E3 TM herbicide tolerance trait for soybeans which provides tolerance to 2, 4-D choline in Enlist Duo ® and Enlist One ® herbicides, as well as glyphosate and glufosinate herbicides. In connection with the validation of breeding plans and large-scale product development timelines, during the fourth quarter of 2019, the company committed to accelerate the ramp up of the Enlist E3 TM trait platform in the company’s soybean portfolio mix across all brands, including Pioneer ® brands, over the subsequent five years. During the ramp-up period, the company has began to significantly reduce the volume of products with the Roundup Ready 2 Yield ® and Roundup Ready 2 Xtend ® herbicide tolerance traits, with expected minimal use of the trait platform thereafter for the remainder of the Roundup Ready 2 License Agreement (the “Transition Plan”). The rate of royalty expense has therefore increased significantly through higher amortization of the prepaid royalty as fewer seeds containing the respective trait are expected to be utilized. In connection with the departure from these traits, beginning January 1, 2020 the company presents and discloses the non-cash accelerated prepaid royalty amortization expense as a component of restructuring and asset related charges - net, in the Consolidated Statement of Operations. The accelerated prepaid royalty amortization expense represents the difference between the rate of amortization based on the revised number of units expected to contain the Roundup Ready 2 Yield ® and Roundup Ready 2 Xtend ® trait technology and the variable cash rate per the Roundup Ready 2 License Agreement.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold primarily includes the cost of manufacture and delivery, ingredients or raw materials, direct salaries, wages and benefits and overhead, non-capitalizable costs associated with capital projects, royalties and other operational expenses. No amortization of intangibles is included within cost of goods sold.
Research and Development	Research and Development Research and development costs are expensed as incurred. Research and development expense includes costs (primarily consisting of employee costs, materials, contract services, research agreements, and other external spend) relating to the discovery and development of new products.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative expenses primarily include selling and marketing expenses, commissions, functional costs, and business management expenses.
Litigation	Litigation and Other ContingenciesAccruals for legal matters and other contingencies are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs, such as outside counsel fees and expenses, are charged to expense in the period incurred.
Severance Costs	Severance CostsSeverance benefits are provided to employees under the company's ongoing benefit arrangements. Severance costs are accrued when management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated.
Insurance and Self Insurance	Insurance/Self-Insurance The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable.
Income Taxes	Income Taxes The company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The current portion of uncertain income tax positions is included in income taxes payable or income tax receivable, and the long-term portion is included in other noncurrent obligations or other noncurrent assets in the Consolidated Balance Sheets.
Earnings Per Share, Policy [Policy Text Block]	Earnings per Common Share The calculation of earnings per common share is based on the weighted-average number of the company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.

Retrospective application to all periods in which a balance sheet is presented is required, except for the rollforward requirement, which will be applied prospectively. The adoption of this guidance will result in the company being required to include certain disclosures relating to supplier financing programs and related obligations.

Revenue from Contract with Cust

Revenue from Contract with Customer (Policies)	12 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition, Sales of Goods	Products Substantially all of Corteva's revenue is derived from product sales. Product sales consist of sales of Corteva's products to farmers, distributors, and manufacturers. Corteva 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. However, the company has some long-term contracts which can span multiple years. Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms are generally less than one year from invoicing. The company elected the practical expedient and does not adjust the promised amount of consideration for the effects of a significant financing component when the company expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. When the company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to or at shipment), these are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, the company elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less. The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates of variable consideration included in the transaction price primarily utilize the expected value method based on historical experience. These estimates are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, the company allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances.
Revenue Recognition, Services, Licensing Fees	Licenses of Intellectual PropertyCorteva enters into licensing arrangements with customers under which it licenses its intellectual property. Revenue from the majority of intellectual property licenses is derived from sales-based royalties.
