The ISF Filing Deadline is 24 hours before cargo is loaded onto a ship that is bound for the U.S. This deadline is mandated and enforced by Customs and Border Protection (CBP). Failure to meet the deadline can result in financial penalties of $5,000 per infraction, delayed cargo, and additional inspections.

When Should an ISF Be Filed?

The ISF 24 hour rule is one of the most important requirements to know about the importer security filing process. An ISF is required to be filed no later than 24 hours before the cargo is loaded onto a ship with a destination of the United States or a foreign trade zone (FTZ). 

The rule specifically applies to the first 8 elements of an ISF:

  • Seller
  • Buyer
  • Importer of record number or FTZ applicant identification number
  • Consignee number(s)
  • Manufacturer (or supplier)
  • Ship to party
  • Country of origin
  • Commodity HTS Code

The other two pieces of information - the container stuffing location and the consolidator - may be submitted later, but no less than 24 hours prior to the ship's arrival at a U.S. port. 

With all that being said, an importer security filing and all of its data elements should be submitted as soon as possible. Submitting the ISF earlier will allow the filer additional time to correct any mistakes and revise the filing if needed.

ISF Late Filing Penalty: What Happens if ISF is Filed Late?

If you fail to file your ISF, or you simply miss the ISF filing deadline, there are several consequences. 

First, if you failed to file the ISF or missed the deadline, the port you arrived at will file a case with the CBP. The CBP will then proceed to file claims for the violations. They can assess damages of $5,000 per infraction, up to $10,000.

These infractions can include: 

  • Failure to file the ISF
  • Late filing
  • Incomplete filing
  • Failure to withdraw the ISF
  • Failure to ensure ISF matches the Bill of Lading

In some cases, CBP may hold your cargo until the proper information has been received and reviewed. The shipment may also be subject to additional inspections.

I purchased a vehicle from Japan, would like to know when would I be filing this ISF form? I were informed when the seller from Japan sends me all documents with ISF form included? If this so. What is the time frame that I should be filing this ISF form to the CBP.

Hi Duyen,

The Importer of Record is ultimately responsible for filing the ISF. Every freight forwarder is different. Some act as the Importer of Record for their clients, while others do not. It would be best to confirm with your freight forwarder who the Importer of Record for your shipment is.

If I'm just ordering a few samples and a few gifts, do I need to file any forms? I ordered some things in different orders from aliexpress. The cost of the orders were very low. All under 20$.

Hi Melinda,

This will depend on what Incoterms the seller uses for your shipments. In some cases, the seller takes care of the necessary customs forms, while in other situations, this is the buyer's responsibility. Someone from our team will reach out to you confirm the Incoterms of your shipment to help you determine if you'll need to submit any forms. We look forward to helping you!
