Search 50 U.S.C. § 224 : US Code - Section 224: Refusing clearance to vessels with suspected cargoes; forfeiture for departing without clearance

The Secretary of the Treasury is authorized to refuse a clearance
to any vessel or other vehicle laden with merchandise, destined for
a foreign or domestic port, whenever he shall have satisfactory
reason to believe that such merchandise, or any part thereof,
whatever may be its ostensible destination, is intended for ports
in possession or under control of insurgents against the United
States; and if any vessel for which a clearance or permit has been
refused by the Secretary of the Treasury, or by his order, shall
depart or attempt to depart for a foreign or domestic port without
being duly cleared or permitted, such vessel, with her tackle,
apparel, furniture, and cargo, shall be forfeited.
