Shipping to USA? You need to know about ISF Filing.

When must an ISF be submitted to Customs and Border Protection (CBP)?

Customs and Border Protection (CBP) began enforcing Import Security Filing (ISF), which is also commonly known as 10+2 through liquidated damages claims on July 9, 2013.  The ISF is required to be submitted to CBP no later than 24 hours prior to the cargo being loaded on the vessel destined to the United States.

The liquidated damages claims amounts are $5000 per violation.

Parties may submit questions about ISF requirements to CBP via the 10+2 Security Filing email box.  [email protected].
