Although the clauses prescribed in subpart 43.2 allow certain changes to be made in regard to shipment and delivery, it may be desirable to provide specifically for certain options in the solicitation. The Government may reserve the right to—

(a) Direct deliveries of all or part of the contract quantity to destinations or to consignees other than those specified in the solicitation and in the contract;

(b) Direct shipments in quantities that may require transportation rates different from those on which the contract price is based; and

(c) Direct shipments by a mode of transportation other than that stipulated in the solicitation and in the contract.
