19 CFR § 4.15 - Fishing vessels touching and trading at foreign places.
(a) Before any vessel documented with a fishery license endorsement shall touch and trade at a foreign port or place, the master shall obtain from the port director a permit on Customs Form 1379 to touch and trade.
28 If such a vessel puts into a foreign port or place and only obtains bunkers, stores, or supplies suitable for a fishing voyage, it is not considered to have touched and traded there. Fish nets and netting are considered vessel equipment and not vessel supplies.
(b) Upon the arrival of a documented vessel with a fishery endorsement which has put into a foreign port or place, the master shall report its arrival, make entry, and conform in all respects to the regulations applicable in the case of a vessel arriving from a foreign port.
(c) If a vessel which has been granted a permit to touch and trade arrives at a port in the United States, whether or not the vessel has touched at a foreign port or place, such permit shall forthwith be surrendered to the port director.
(d) No permit to touch and trade shall be issued to a vessel which does not have a Certificate of Documentation with a fishery license endorsement.
