(a) F.o.b. destination. 49 U.S.C. 10721 and 13712 rates do not apply to shipments under fixed-price f.o.b. destination contracts (delivered price).

(b) F.o.b. origin. If it is advantageous to the Government, the contracting officer may occasionally require the contractor to prepay the freight charges to a specific destination. In such cases, the contractor shall use a commercial bill of lading and be reimbursed for the direct and actual transportation cost as a separate item in the invoice. The clause at 52.247-1, Commercial Bill of Lading Notations, will ensure that the Government in this type of arrangement obtains the benefit of 49 U.S.C. 10721 and 13712 rates.
