In the world of international shipping, ensuring compliance with customs regulations is paramount. One such critical requirement for shipping goods to the United States is the Importer Security Filing (ISF). Often referred to as the “10+2” filing, ISF is a mandatory step for ocean freight shipments bound for the US. It helps US Customs and Border Protection (CBP) improve security measures and manage risks associated with imported cargo.
This guide explores what ISF filing is, why it is essential, how to file it correctly, and the consequences of failing to comply with its requirements.
