The Importer Security Filing (ISF)—commonly referred to as the ISF 10+2 rule—is a mandatory requirement enforced by U.S. Customs and Border Protection (CBP). It requires importers to electronically submit 10 specific data elements about the cargo, seller, buyer, and routing, while carriers must provide 2 additional elements related to the vessel and container status. This information must be filed at least 24 hours before cargo is loaded onto an ocean vessel destined for the United States.

The purpose of the ISF rule is to enhance cargo visibility, strengthen national security, and allow CBP to assess and manage risk before goods arrive at U.S. ports. Proper and timely filing is essential for avoiding delays, holds, or monetary penalties that can significantly disrupt your supply chain.
