§ 301-5.5 - Requirement for use of least costly means of shipment.

(a) Selection of transportation service. When the total weight of Government property and personal effects or other property needed by the traveler exceeds the baggage allowance, quantities in excess of the allowance shall be shipped by parcel post, where practical, or, if not suitable for mailing, by freight or express if any of those less costly means of shipment will suffice. Shipments must not be made as accompanied baggage or express when ordinary freight service will meet the official needs. Due consideration must be given to the probable cost of collecting or delivering the shipment and the time required for transmission.

(b) Use of Government bills of lading. Express and freight shipments shall be made on Government bills of lading unless such handling will interfere with the official purposes of the trip or unless it is not practical. Charges on shipments made on Government bills of lading must not be paid by the traveler.
