Which document is used for interdepartmental purchase requests?

• A. AF Form 9, Request for Purchase
• B. AF Form 616, Fund Cite Authorization
• C. DD Form 448, Military Interdepartmental Purchase Request
• D. AF Form 406, Miscellaneous Obligation/Reimbursement Document

Answer: (C)

Interdepartmental purchasing within DoD relies on a standard document that formalizes a request from one component to another and aligns funding. The Military Interdepartmental Purchase Request, documented on the DD Form 448, is designed for these cross-component transactions. It captures who is requesting, what is needed, the estimated cost, delivery requirements, and the funding authority (fund cite) so the supplying component can obligate funds and fulfill the purchase. This keeps interdepartmental buys transparent, auditable, and properly funded across the DoD.

Other forms serve different procurement pathways. The AF Form 9 is a general request for purchase used within Air Force supply processes when procuring from vendors through AF channels, not for interdepartmental transfers. The AF Form 616 Fund Cite Authorization is used to document and justify the funds to be obligated, but it isn’t the request itself for interdepartmental purchases. The AF Form 406 is for miscellaneous obligations or reimbursements, not for initiating interdepartmental purchases.
