Importer Security Filing (ISF), also known as "10+2", is a US Customs requirement that importers (or their agents) must file specific data elements at least 24 hours before cargo is loaded onto a US-bound vessel.

The "10+2" refers to: Importer (10 data elements): 1. Seller name and address 2. Buyer name and address 3. Importer of record number 4. Consignee number 5. Manufacturer/supplier name and address 6. Ship to party 7. Country of origin 8. Harmonized Tariff Schedule (HTS) number (6-digit) 9. Container stuffing location 10. Consolidator name and address

Carrier (2 data elements): 1. Vessel stow plan 2. Container status messages

The ISF fee charged by forwarders covers filing services, system costs, and compliance management.
