Revenue from Contract with Customer [Abstract]

Revenue Recognition, Sales of Goods

Products

Substantially all of DuPont's revenue is derived from product sales. Product sales consist of sales of DuPont's products to supply manufacturers, distributors, and farmers. DuPont considers purchase orders, which in some cases are governed by master supply agreements, to be a contract with a customer. Contracts with customers are considered to be short-term when the time between order confirmation and satisfaction of the performance obligations is equal to or less than one year.

Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms for contracts related to product lines other than agriculture generally average 30 to 60 days after invoicing, depending on business and geography. Payment terms for agriculture product line contracts are generally less than one year from invoicing. The company elected the practical expedient and will not adjust the promised amount of consideration for the effects of a significant financing component when DuPont expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. The company has elected to recognize shipping and handling activities when control has transferred to the customer as an expense in cost of goods sold. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, DuPont elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less.

The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates for variable consideration are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, DuPont allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances.

Revenue Recognition, Licenses of Intellectual Property

Licenses of Intellectual Property

DuPont enters into licensing arrangements with customers under which it licenses its intellectual property, such as patents and trademarks. Revenue from the majority of intellectual property licenses is derived from sales-based royalties. The company estimates the expected amount of sales-based royalties based on historical sales by customer. Revenue for licensing agreements that contain sales-based royalties is recognized at the later of (i) when the subsequent sale occurs or (ii) when the performance obligation to which some or all of the royalty has been allocated is satisfied.
