(1) Requiring departments send their requirements to acquiring departments on either a DD Form 448, Military Interdepartmental Purchase Request (MIPR), or a DD Form 416, Requisition for Coal, Coke or Briquettes. A MIPR or a DD Form 416 is the acquiring department's authority to acquire the supplies or services on behalf of the requiring department.

(2) The acquiring department is authorized to create obligations against the funds cited in a MIPR without further referral to the requiring department. The acquiring department has no responsibility to determine the validity of a stated requirement in an approved MIPR, but it should bring apparent errors in the requirement to the attention of the requiring department.

(3) Changes that affect the contents of the MIPR must be processed as a MIPR amendment regardless of the status of the MIPR. The requiring department may initially transmit changes electronically or by some other expedited means, but must confirm changes by a MIPR amendment.

(4) The requiring department must submit requirements for additional line items of supplies or services not provided for in the original MIPR as a new MIPR. The requiring department may use a MIPR amendment for increased quantities only if—

(i) The original MIPR requirements have not been released for solicitation; and

(ii) The acquiring department agrees.
