Importer Security Filing

Deringer’s electronic solution to satisfy the Importer Security Filing (ISF) requirements not only ensures the submission of required data elements in a timely and compliant manner, but also helps manage the data in a central location, as well as add visibility to supply chains. Based on a client’s specific processes, Deringer offers a variety of options to enable clients to store and manage pertinent information on all products and assist in making the Importer Security Filing requirements as seamless as possible. We also offer the convenience of a unified filing (filing of a Customs entry as well as the ISF).

US Customs and Border Protection (CBP) began enforcing ISF in 2010.  The ISF requires importers, using ocean transportation that call a US port directly, to provide ten additional data elements to CBP. Like Customs entries, a single transaction bond (Appendix D ISF Stand-Alone STB or Unified Filing, CBP Form 301 STB) or a continuous bond (Appendix D ISF Stand-Alone Continuous Bond or Existing CBP Form 301 Continuous Bond) is required for ISF transactions.  Carriers are required to submit two additional data elements.

CBP provides a monthly ISF report card detailing importers compliance with the requirement.  An explanation of the report card is available here. Based on its strong relationship with CBP, Deringer was provided the ability to beta test ISF transmissions with importers as soon as CBP afforded members of the trade access, which resulted in Deringer being one of the first brokers able to provide an Importer Security Filing solution.
