All about ISF (10+2) filing


About ISF

In January 2009, the CBP published a new regulation mandated for ocean cargo imports only.
The ISF (Importer Security Filing), also known as ISF (10+2) or just “10+2”, is a filing required by the CBP for ocean cargo, and is an integral part of the US customs clearance process.

The information submitted in ISF improves U.S. Customs and Border Protection’s (CBP) ability to identify high-risk shipments in order to prevent smuggling and ensure cargo safety and security.

The importer is held responsible for filing the ISF, and the information must be transmitted to the CBP at least 24 hours before the vessel containing the goods leaves the last port of origin to the US.
Failure to comply with the rule could ultimately result in monetary penalties of up to $5000, increased inspections, and delay of cargo.

• Bill of lading and Commercial Invoice
• International classification HTS 6-digit numbers for your products
• Customs Bond (single or continuous) needed only if cargo value is above 2500$

If you fulfill these requirements the process of self-filing your ISF is self-explanatory and straightforward, you do not need to fill out forms manually, all you have to do is fill in the relevant fields online, pay only $10, and automatically submit your application to CBP.

If you don’t have an ISF Customs Bond you can send a purchase request for it during the ISF filing process.

After the ISF is sent, you will receive regular updates from the system regarding the status of the application, until the ISF is approved by the CBP or completion/repairs needed by the CBP.
If completion is required, you can make the required repairs and submit an updated ISF with no additional fees.

DON’T wait for the last minute, file your ISF as soon as you can to avoid CBP fines and penalties
