On July 6, 2016, U.S. Customs and Border Protection (CBP) published in the Federal Register¬ a notice of proposed rulemaking [USCBP-2016-0040] to amend the CBP regulations to expand the definition of Importer Security Filing (ISF) Importer for certain types of shipments (foreign cargo remaining on board (FROB), immediate exportation (IE), and transportation and exportation (T&E) in-bond shipments, and for merchandise being entered into a foreign trade zone (FTZ)) to ensure that the party that has the best access to the required information will be the party that is responsible for filing the ISF The Importer Security Filing and Additional Carrier Requirements regulations (Title 19 C.F.R. Part 149) were implemented in 2009 as an interim final rule to improve CBP’s ability to identify high-risk shipments in order to prevent smuggling and improve cargo safety and security. These regulations require certain cargo information to be submitted to CBP via an ISF before the cargo is loaded on a vessel that is destined to the United States. These regulations fulfill the requirements of section 203 of the SAFE Port Act of 2006 and section 343 of the Trade Act of 2002, as amended by the Maritime Transportation Security Act of 2002. The ISF Importer is the party that is required to file the ISF. Comments must be received on or before September 6, 2016.
