Importer Security Filing (ISF)

Definition of Importer Security Filing


The Importer Security Filing (ISF), also known as the "10+2" rule, is a compliance measure for importers shipping goods into the United States via ocean freight. 

Introduced by U.S. Customs and Border Protection (CBP), the ISF requires importers to provide specific data elements about their cargo before it is loaded onto a vessel at the port of origin.

The ISF involves submitting 10 key data elements that pertain to the importer, buyer, seller, and shipment details, along with 2 additional data elements provided by the carrier. 

These details include information like the seller's and buyer's name and address, the country of origin, the Harmonized Tariff Schedule (HTS) number, and the container stuffing location. The goal is to pre-screen shipments for security risks before they reach U.S. shores.

Who charges for Importer Security Filing?


Although importers can file the ISF themselves, they often engage customs brokers or freight forwarders to manage the process due to its complexity.

Where is Importer Security Filing charged?


ISF fees are paid at the time of filing, which occurs well before the goods arrive at a U.S. port. The ISF must be submitted at least 24 hours before the cargo is loaded onto the vessel at the foreign port.

Consequences of late filing 


Failing to submit the ISF on time can result in penalties, with fines reaching up to £8,000 per shipment. 

Common reasons for penalties include late filings, missing or incorrect data, and failure to update the ISF if information changes. Beyond fines, non-compliance can lead to cargo holds, delays in clearance, and increased inspections. 

ISF penalties 


ISF penalties are strict and can escalate based on the frequency and severity of violations.
