122
the owner or agent of the vessel immediately shall give notice of the diversion to the port director who granted the permit, informing him of the new destination of the vessel and requesting him to notify the director of the latter port. Such notification by the port director shall constitute an amendment of the permit previously granted, shall authorize the vessel to proceed to the new destination, and shall be filed by the director of the latter port with the Form 1300 submitted on entry of the vessel.
(b) If any vessel cleared from a port in the United States for a foreign port as provided for in § 4.60 is diverted, while en route, to a port in the United States other than that from which it was cleared, the owner or agent of the vessel immediately shall give notice of the diversion to the port director who granted the clearance, informing him of the new destination of the vessel and requesting him to notify the director of the latter port. Such notification by the port director shall constitute a permit to proceed coastwise, and shall authorize the vessel to proceed to the new destination. On arrival at the new destination, the master shall immediately report arrival. He shall also make entry within 48 hours by presenting (1) the vessel's document, (2) the foreign clearance on Form 1300 granted by the director of the port of departure, (3) a certificate that when the vessel was cleared from the last previous port in the United States there were on board cargo and/or passengers for the ports named in the foreign clearance certificate only and that additional cargo or passengers (have) (have not) been taken on board or discharged since such clearance was granted (specifying the particulars if any passengers or cargo were taken on board or discharged), (4) a Crew's Effects Declaration in duplicate of all unentered articles acquired abroad by the officers and crew of the vessel which are still retained on board, and (5) a Ship's Stores Declaration in duplicate of the stores on board.

all cargo and passengers from one vessel of the United States to another such vessel under Customs supervision, if the first vessel is transporting residue cargo for domestic or foreign ports or is on an outward foreign voyage or a voyage to noncontiguous territory of the United States, and is following the procedure prescribed in § 4.85, § 4.87, or § 4.88. When inward foreign cargo or passengers are so transshipped to another vessel, a separate traveling manifest (Cargo Declaration, Customs Form 1302, or updated data elements required on CBP Form I-418 that were submitted electronically via an electronic data interchange system approved by CBP) shall be used for the transshipped cargo or passengers, whether or not the forwarding vessel is also carrying other residue cargo or passengers. An appropriate cross-reference shall be made on the separate traveling manifest to show whether any other traveling manifest is being carried forward on the same vessel.
