Discover Importer Security Filing efficiency and compliance in one package.
The Importer Security Filing (ISF) rule applies to import cargo arriving in the United States by vessel. Failure to comply with the rule could ultimately result in monetary penalties, increased inspections and delay of cargo. CBP can assess liquidated damages of $5,000 USD per violation, up to $10,000 per filing, for late or inaccurate ISF filings.
To facilitate the ISF filing process, Deringer provides user-friendly, electronic options to satisfy ISF requirements—including a fillable form or online portal that retains data for future ISF transactions. Our online platform enables clients to store and manage pertinent information on all products and assists in making the ISF filing process as seamless as possible. Additionally, we guide our customers through the monthly ISF report card provided by CBP.
What is ISF?
ISF is a CBP regulation requiring importers and ocean carriers to report specific data elements regarding ocean shipments entering the US. The regulations require transmission of ten data elements at least 24 hours prior to vessel lading for containerized freight and 24 hours prior to arrival at the port of discharge for break bulk cargo (bulk cargo is exempt from ISF). Cargo that is Foreign Remaining On Board (FROB) is required to submit only five data elements. These abbreviated filings are required for freight remaining on board a vessel that is docking in the US prior to moving to a foreign destination or cargo moving in-bond through the US to a foreign country.
ISF is a separate transaction that does not replace the CBP entry. However, similar to Customs entries, a single transaction bond or a continuous bond is required for ISF transactions. CBP sends a message of acceptance or rejection to the ISF filer confirming that the filing has been successfully submitted. However, CBP will not validate whether the data is complete and accurately transmitted, as this is the responsibility of the importer of record (IOR).
