What is ISF?

The Importer Security Filing (ISF), also known as 10+2, is a US Customs and Border Protection (CBP) regulation requiring importers and vessel carriers to provide data electronically to CBP for in-bound ocean shipments.

Failure to comply with the rule could ultimately result in monetary penalties, increased inspections and delay of cargo.  

More information can be found on, the official website of the Department of Homeland Security.

ISF penalties are up to $10,000 per shipment

Customs can assess liquidated damages up to $10,000.00 for violations such as failure to submit the ISF timely, accurately, or completely against the holder of the bond posted for the ISF or the importer of record.


Submit Power of Attorney

You will need to submit a completed Customs Power of Attorney. The Power of Attorney allows Heizwerthy to transact customs business on your behalf. All US Customs brokers are mandated to have a valid Power of Attorney on file prior to transacting any customs business on behalf of the importer.  



Determine Bond Type

If you are importing merchandise into the U.S. for commercial purposes that are valued over $2,500, or a commodity subject to other federal agencies requirements (i.e. firearms or food), you must post a Customs bond to ensure that all duties, taxes and fees owed to the federal government will be paid.

You have the option of obtaining a “continuous bond”, “single entry” and/or an “ISF bond”. The type(s) of bond you elect to obtain ultimately depends on how often you import into the U.S.  For instance, if you only import on occasion, the single entry bond is recommended. If you import frequently (3 or more shipments annually) and through various ports of entry, the continuous bond is beneficial and economically the best choice.

A continuous bond covers all of your transactions INCLUDING ISF filings for a period of one year.   If you opt to obtain a single entry bond for your customs entry, you must also obtain an ISF bond to file your ISF each time you import a shipment.
