Importer Security Filing 037 – What is the ISF 5 rule?

What is the ISF 5?

This is a requirement for a foreign cargo that will touch the U.S. territory for in transit. 

FROB (Freight Remaining on Board) – means cargo which is laden in a foreign port, is intended for discharge in a foreign port, and remains aboard a vessel during either direct or indirect stops at one or more intervening United States ports.

(T&E and I&E) In bond – The transportation and exportation bond system is valuable to transport services and people moving objects through the United States, because it allows them to avoid paying duties to the country for items that aren’t really being imported.

Bond Requirement:

The carrier delegates the freight forwarder/broker using its own bond to file an ISF5.
