19 U.S.C. § 1706a — Civil penalties for trading without required certificate of documentation

Whenever a vessel, entitled to be documented and not so documented, is employed in a trade for which certificates of documentation are issued under the vessel documentation laws, other than a trade covered by a registry, the vessel is liable to a civil penalty of $500 for each port at which it arrives without the proper certificate of documentation, and if it has on board any merchandise of foreign growth or manufacture (sea stores excepted), or any taxable domestic spirits, wines, or other alcoholic liquors, on which the duties or taxes have not been paid or secured to be paid, the vessel, together with its equipment and cargo, is liable to seizure and forfeiture. Marks, labels, brands, or stamps, indicative of foreign origin, upon or accompanying merchandise or containers of merchandise found on board such vessel, shall be prima facie evidence of the foreign origin of such merchandise.
