What is the primary purpose of an Importer Security Filing (ISF)?

The primary purpose of an Importer Security Filing (ISF) is to provide U.S. Customs and Border Protection (CBP) with advance data on cargo arriving in the United States. This advance information allows CBP to assess potential security risks associated with the incoming shipments before they reach U.S. shores. By obtaining data about the contents and origins of cargo, CBP can effectively target and mitigate any threats, ensuring safe and secure international shipping practices.

While expediting the customs clearance process is a benefit of providing such advanced data, the core function of the ISF is centered on security and risk assessment. Tracking the movement of imported goods and establishing their value are important aspects of international trade, but they serve different purposes and fall under other customs documentation and processes. The ISF specifically focuses on the pre-arrival information required to enhance national security.
