Importer Security Filing Requirements#
The Importer Security Filing (ISF or 10+2) must be filed at least 24 hours before ocean cargo is loaded onto a vessel destined for the US. Ten data elements from the importer, two from the carrier. Late filing: $5,000 penalty per occurrence. Inaccurate filing: $5,000 penalty. No filing: cargo hold and potential seizure.
Getting ISF Data from Suppliers on Time#
The biggest ISF challenge: getting accurate data from overseas suppliers 48+ hours before vessel loading. Required data includes manufacturer name and address, seller, buyer, HTS codes, and container stuffing location. Build ISF requirements into purchase orders. Suppliers who can't provide timely data cost you in penalties.
If you receive a penalty notice, you can petition for mitigation within 60 days.
ISF Penalty Mitigation Strategies#
If you receive a penalty notice, you can petition for mitigation within 60 days. First-time penalties are often reduced 50-75% with a strong compliance narrative. Document your ISF procedures, training records, and corrective actions. Repeat offenders get minimal relief. Invest in automation — manual ISF processes fail at scale.
