FAR 52.251—[Reserved]

Government Supply Sources.

FAR 52.251-1, Government Supply Sources, is a short but important clause that governs when a contractor may use Government-owned supply sources to perform a contract. It addresses four core topics: the contracting officer’s authority to issue an authorization, the contractor’s ability to obtain supplies from Government sources only when authorized, the ownership of property acquired under that authorization, and the application of the Government Property clause at FAR 52.245-1 to that property. In practice, the clause is used to control access to Government inventories, depots, or other supply channels and to make clear that items obtained through those channels generally become Government property rather than contractor-owned property. This matters because it affects purchasing procedures, property accountability, risk of loss, recordkeeping, and how the contractor must manage, use, and dispose of the acquired items. The clause also helps ensure that Government supply sources are used only when the contract and the contracting officer permit it, rather than as a default procurement method. For contractors, the key significance is that authorization is required and property rules follow immediately once the authorization is granted; for contracting officers, the key significance is maintaining control over when Government supply sources may be used and how resulting property is treated.

Interagency Fleet Management System Vehicles and Related Services.

FAR 52.251-2, Interagency Fleet Management System Vehicles and Related Services, addresses when and how a contractor may use government fleet vehicles and related support services through the Interagency Fleet Management System (IFMS) to perform a contract. The clause gives the Contracting Officer discretion to issue an authorization, rather than creating an automatic right for the contractor to obtain vehicles or services. It also incorporates compliance with the applicable government motor vehicle rules in 41 CFR part 101-39 and 41 CFR 101-38.301-1, which govern the use, service, and maintenance of IFMS vehicles and the use of related services. In practice, this clause matters when contract performance requires government-furnished transportation resources, because it controls access, operating rules, and maintenance responsibilities. It helps ensure that IFMS assets are used only for authorized contract performance and handled consistently with federal fleet management requirements. Contractors and contracting officers should treat the authorization as a controlled administrative arrangement, not a general entitlement, and should verify the governing fleet regulations before using the vehicles or services.
