Supplies: preference to United States vessels

§ 2631. Supplies: preference to United States vessels Only vessels of the United States or belonging to the United States may be used in the transportation by sea of supplies bought for the Army, Navy, Air Force, or Marine Corps. However, if the President finds that the freight charged by those vessels is excessive or otherwise unreasonable, contracts for transportation may be made as otherwise provided by law. Charges made for the transportation of those supplies by those vessels may not be higher than the charges made for transporting like goods for private persons.
