Los Angeles/Long Beach Seaport ISF Enforcement


Importer Security Filing (ISF) policy requires that all ISF information on a shipment bound for the U.S. must be submitted to U.S. Customs and Border Protection (CBP) 24 hours prior to lading on the vessel at the foreign port. In July of 2013, CBP implemented a strategy to improve ISF compliance.

CBP at the LA/LB Seaport has been enforcing ISF policy 48 hours prior to a vessel arriving at the port. Per CSMS message #14-000520, on October 1, 2014, the LA/LB Seaport will increase enforcement for ISF “no-file” shipments. They will continue to place manifest holds on all cargo that does not have an ISF on file 72 hours before a vessel arrives at the seaport and will monitor existing holds to ensure the ISF information is filed.

CBP will determine if ISF information submitted warrants additional enforcement actions, including liquidated damages, for repeat “no file” offenders.

The trade community may contact CBP via email at the LA/LB Seaport, after vessel arrival, to request shipment status at
