Importer Security Filing (ISF)

Back to Glossary

 

What is the Importer Security Filing?

Importer Security Filing (ISF), also known as “10+2,” is a mandatory U.S. Customs and Border Protection (CBP) requirement for ocean cargo imports into the United States, under which importers must electronically submit 10 specific data elements at least 24 hours before the cargo is loaded onto a vessel at the foreign port. 

The filing enhances supply chain security by allowing CBP to conduct advance risk assessments, requires the importer to have an ISF bond in place, and applies to most containerised ocean shipments. Failure to file on time, filing inaccurate data, or non-compliance can result in penalties of USD 5,000 or more per violation, cargo holds, and increased scrutiny by customs authorities.

The Purpose of the Importer Security Filing 

The primary goal of the Importer Security Filing is to enhance security measures at U.S. ports. By collecting information in advance, CBP can more effectively assess the risks associated with cargo shipments. This preemptive analysis is part of a broader effort to protect the nation from potential threats. Thus, ISF not only aids in logistics but also plays a vital role in national security.

Required Data Elements for an ISF Filing

Complying with ISF involves submitting ten key data elements. These include the seller's details, the buyer's information, and the importer's record. It's also necessary to provide data about the manufacturer, country of origin, and the commodity's Harmonised Tariff Schedule (HTSUS) number. Additionally, details such as the location of container stuffing and the party responsible for shipping, known as the consolidator, are mandatory. Failing to provide accurate information can result in severe penalties.

ISF Filing Responsibilities

The responsibility of filing an ISF typically falls on the importer or their designated agent. This means they must ensure all information is complete and correct. Working with a reliable customs broker or freight forwarder can simplify this process. These professionals are familiar with the regulations and can help prevent costly mistakes. Importers should also stay informed about any changes in ISF requirements, as non-compliance could disrupt shipments.

Advantages of Timely ISF Filing

Beyond avoiding fines, timely filing of the ISF offers several advantages. It enhances visibility into the supply chain, facilitating smoother operations and improved efficiency. Proper filing can also minimise the likelihood of inspections, expediting the clearance of goods at the port. In this way, ISF compliance serves not only a regulatory function but also provides practical benefits for daily business activities.
