FAR 16.501—[Reserved]

Definitions.

FAR 16.501-1 provides the core definitions used in the indefinite-delivery contracting subpart by distinguishing a delivery-order contract from a task-order contract. It explains that a delivery-order contract is for supplies and does not commit the government to a firm quantity of supplies, except for any stated minimum or maximum, while a task-order contract is for services and likewise does not commit the government to a firm quantity of services beyond any minimum or maximum. The section matters because these definitions determine how agencies structure requirements, compete awards, issue orders, and manage performance under indefinite-delivery arrangements. In practice, the distinction between supplies and services affects solicitation language, contract administration, ordering procedures, and how contractors understand the scope of future work. The definitions also make clear that the contract itself establishes the framework for later orders, rather than fixing all quantities up front. For contracting officers and contractors, this section is the starting point for identifying whether a contemplated vehicle is a delivery-order contract or a task-order contract and for ensuring the contract is drafted and used consistently with that classification.

General.

FAR 16.501-2 explains the basic framework for indefinite-delivery contracting and when it is appropriate to use these contract types. It identifies the three forms of indefinite-delivery contracts—definite-quantity, requirements, and indefinite-quantity—and explains that they are used when the Government does not know the exact timing or quantity of future deliveries at award. The section also notes that requirements and indefinite-quantity contracts are commonly referred to as delivery-order contracts or task-order contracts under the cited statutes. It then describes the practical advantages of each type, including reduced inventory, direct shipment to users, flexibility in ordering, and the Government’s limited obligation under indefinite-quantity contracts. Finally, it states that indefinite-delivery contracts may use any appropriate cost or pricing arrangement under FAR part 16, but if the arrangement is based on estimated quantities such as labor hours, the contract must follow the procedures applicable to that type of pricing structure. In practice, this section helps contracting officers choose the right indefinite-delivery vehicle and helps contractors understand how ordering, funding exposure, and pricing structure will work over the life of the contract.
