The Importer Security Filing (ISF) rule, also known as ISF 10+2,
relates to import cargo coming into the U.S. via ocean vessel. The
rule states that an ISF Importer, or their agent, must
electronically submit certain advance cargo information to Customs
and Border Patrol (CBP) before the goods arrive into the U.S. It is
important to note that bulk cargo is not subject to this rule.
The Importer Security Filing is completed by the ISF Importer.
Generally, the ISF Importer is the party causing the goods to
arrive within the limits of a port in the U.S. by vessel. For
foreign cargo remaining on board (FROB shipments), the ISF importer
is the carrier. For immediate exportation (IE) and transportation
and exportation (T&E) in-bond shipments, and goods to be
delivered to a foreign trade zone (FTZ), the ISF Importer is the
party filing the related documentation.
