What Is ISF (10+2)?
The US security filing requirement for all ocean cargo entering the United States.
The Importer Security Filing (ISF), commonly called '10+2', is a US CBP requirement.
The '10+2' name comes from its structure: the importer provides 10 data elements, and the carrier provides 2.
ISF applies to ALL ocean containerized cargo, regardless of value.
