ISF 10+2 before the vessel sails
For covered vessel shipments, the importer security filing provides advance data so CBP can assess risk before cargo reaches the United States. Most required importer data is due before vessel loading, subject to the regulation’s details and exceptions.
The four-step journey
Understand the advance importer and carrier data used for vessel security screening and why late or inaccurate ISF data creates risk.
- Booking and supplier data are gathered

- Carrier contributes vessel data
- Updates and arrival events are monitored
What the broker checks
- Correct ISF importer and bond
- Manufacturer, seller, buyer, ship-to, origin, and HTS data
- Timing, bill matching, and amendments
Why it matters
ISF is an upstream data discipline. Waiting for the entry packet can already be too late.
