ISF (Offline File)
Key to file ISF
The key to file ISF is that you must file 48 hours (we prefer 72 hours) before your consignment can be loaded into a freight vessel, even if your data is incomplete. You can always modify your ISF filing and re-submit it 72 hours before your shipment arrives at a U.S. port. However, you must re-submit your ISF; otherwise, CBP can and will impose a penalty / fee of up to $5,000 for each infringement.
Importers are responsible for filing an Importer Security Filing (ISF 10+2) as of January 26, 2010. Separate from the carrier's manifest and the broker's / importer's entry / entry file / custom broker is the Importer Security Filing (ISF 10+2).
NOTE: For each bill of lading (BL) / shipment, the ISF 10+2 filing is required. Also, each Importer Security Filing (ISF 10+2) must have the same parameters, such as spelling of all names, letters, and numbers on your oversea factory's shipments / invoices.
