What Is ISF Filing?

ISF, short for Importer Security Filing, involves the electronic submission of vital cargo data by the importer or their authorized agents to the U.S. Customs and Border Protection (CBP) service. This data must be submitted no later than 24 hours before a shipment is loaded onto the vessel at the port of origin.

It’s meant to provide the CBP with relevant cargo information and threat assessment before it arrives at the destination country. It also helps them track the cargo’s transit history, determine if the freight is high-risk, and prevent the entry or smuggling of illicit or prohibited goods into the country.

Also referred to as “10+2” because of the two separate data types or groups that must be entered, the CBP primarily requires this for containerized, Ro-Ro, and break-bulk ocean freight that’s headed for the United States.

The Importer Security Filing document must contain the following information:

  1. Supplier’s or manufacturer’s details (Name and address)
  2. Seller or vendor’s contact details, including name and address
  3. Buyer or importer’s contact information 
  4. Importer of Record number or Foreign Trade Zone (FTZ) Applicant ID number (Entity handling duties and compliance)
  5. Consignee number
  6. Country of Origin
  7. “Ship to” entity (cargo receiver’s name and address)
  8. Container stuffing location
  9. Consolidator or cargo stuffer’s details (name and address)
  10. Commodity Harmonized Tariff Schedule (HTS) number for each product type in the cargo (must be a minimum of 6 digits)

The other two data elements include:

  1. Container status messages (provides updates on the status of the container while in transit)
  2. Vessel stow plan (provides information regarding how/where the container is stowed on the freight carrier)

Who Is Responsible for ISF Filing?

The importer or shipper or their representative (usually a freight forwarder, customs broker, or an ISF filing service provider) supplies the first ten (10) data elements, and the vessel operator or carrier provides the last two (2) container tracking data.

Note: All information must be accurate and submitted on time. Late submissions or errors that aren’t corrected on time (at least 24 hours before the cargo is loaded onto the vessel at the port of departure) can attract severe penalties.

Role of an ISF Filing Service

Due to the types of data required, filing an ISF is often a delicate affair. One error or typo, and you could potentially be on the hook for a large fine. When it comes to unsuccessful or inaccurate ISF filings, it’s usually what you don’t know that affects you. 

In fact, in many instances where SMB importer have been fined because of their mistakes, it was because of their “ignorance.” For many SMB importers, self-filing is too risky and has costly outcomes if mistakes are made. This is why ISF filing services can be helpful, particularly those familiar with your freight. 

The service can handle the following on your behalf:

  • Prepare accurate data and submit it electronically to the CBP through the Automated Broker Interface (ABI) or the Automated Commercial Environment (ACE).
  • Track, correct, and update all necessary data on time.
  • Follow up on the ISF status.
  • Ensure that all submissions comply with established regulations.
  • Provide real-time shipment tracking information.
  • Help expedite customs clearance with timely document and data submissions.
  • Use properly vetted data entry software to minimize data errors.
  • Provide expert guidance on complex regulations and help to reduce possible inaccuracies during filing.
  • Track HTS classification changes, thus ensuring you enter only accurate information.
  • Monitor new regulations so that your shipments are classified appropriately when there are changes.
  • Provide peace of mind in the event of a CBP audit and help you confidently complete the Exhibit-2A form (pre-assessment survey).

How to File ISF Correctly

Here’s a simple step-by-step guide to effective and accurate ISF Filing:

  • Collate necessary data points: Make sure they’re accurate or correct. This is the most crucial step because if you make a mistake or there’s an error, it’ll adversely impact the other steps, leading to possible penalties and fines. 
  • Sign up for the ACE Portal: ACE stands for Automated Commercial Environment. This is the Customs and Border Protection Agency’s portal for filing and submitting many forms, including the ISF. If you’re a new user, simply create an account on the ACE Portal and fill out the details. 
  • Use the ABI feature: Look for the Automated Broker Interface (ABI) feature, click the ISF tab/link, and enter the data elements into the designated interface. Your approved agent or representative can also do this on your behalf. 
  • Cross-check your data: Once you’ve filled out the interface, double/triple-check the data to ensure it’s correct.
  • Track/monitor the ISF status: After submission, monitor your ISF status to ensure it’s approved. If it’s rejected, make the necessary corrections. 

When submitting the data elements, please note that details like the manufacturer or supplier, HTS number, and country of origin must be linked as a line item.

How to Avoid ISF Penalties and Compliance Issues

To avoid being penalized by the CBP for your ISF filing, do the following:

  • Enter accurate data: Ensure that the information submitted is correct. Inaccurate or incorrect data submission can result in penalties. 
  • Avoid late ISF filing: The filing must be done at the latest 24 hours before shipment loading at the origin port. 
  • Amend errors immediately: If there are mistakes, make the corrections and resubmit the up-to-date and correct data quickly and within the allotted timeframe – flexible ISF has a 24-hour deadline before shipment arrival for all updates. 
  • Always file an ISF: All cargo entering the United States must have an ISF on file. Failure to file one will attract penalties. 
  • Submit coherent supporting documents: The ISF information must match that of the bill of lading and other shipping documents. Discrepancies between the ISF and other shipping documents are considered a violation, which may lead to fines.
