A Step-by-Step Guide to Creating an ISF File for Importers

If you are involved in importing goods into the United States, you have likely encountered the Importer Security Filing (ISF) requirement. A common question among importers is, “how do I create an ISF file?“ Understanding this process is crucial to ensuring compliance with U.S. Customs and Border Protection (CBP) regulations and avoiding costly penalties. This guide will walk you through the key steps of creating an ISF file, its importance, and how to submit it properly.

What is an ISF Filing?

The Importer Security Filing (ISF), also known as “10+2“, is a mandatory electronic filing required by CBP for ocean cargo shipments entering the U.S. It provides CBP with advance shipment information, helping to identify potential security threats before cargo arrives.

The ISF must be filed at least 24 hours before the vessel departs from the foreign port, and failure to comply can result in fines and shipment delays.

Key Data Elements of an ISF

An ISF submission consists of 10 data elements for importers and 2 additional elements for ocean carriers.

Importer’s 10 Elements:

1. Seller Name & Address – The party selling the goods.
2. Buyer Name & Address – The U.S. buyer receiving the goods.
3. Importer of Record Number – EIN, SSN, or Customs Assigned Number.
4. Consignee Number – IRS, EIN, or SSN of the consignee.
5. Manufacturer (Supplier) Name & Address – The entity that made the goods.
6. Ship-to Party – The final delivery destination in the U.S.
7. Country of Origin – Where the goods were manufactured.
8. Harmonized Tariff Schedule (HTS) Code – The classification of goods.
9. Container Stuffing Location – Where the container was packed.
10. Consolidator Name & Address – The party responsible for loading the container.

Carrier’s 2 Additional Elements:

1. Vessel Stow Plan – Shows cargo placement on the vessel.
2. Container Status Messages – Reports on the movement and status of containers.

Steps to Create an ISF File

Step 1: Gather Required Information

Before creating an ISF file, ensure you have collected all the necessary details from suppliers, freight forwarders, and carriers. Missing or incorrect data can lead to CBP penalties.

Step 2: Choose a Filing Method

You can submit an ISF through:

• A Licensed Customs Broker – Many importers use a customs broker to ensure compliance.
• Self-Filing Using a CBP-Approved Software – If you have direct access to the Automated Broker Interface (ABI), you can file on your own.
• Freight Forwarder or NVOCC (Non-Vessel Operating Common Carrier) – Some logistics providers offer ISF filing services.

Step 3: Prepare the ISF File

Most ISF submissions are done electronically through CBP-approved systems. If using ISF filing software, follow these steps:

1. Log into the ISF portal or filing software.
2. Enter the required shipment details (Seller, Buyer, HTS Code, etc.).
3. Verify the accuracy of the data.
4. Save the file in the required electronic format.
5. Submit the ISF to CBP through the ABI system.

Step 4: Receive and Verify Confirmation

Once submitted, CBP will send an ISF Filing Status Update confirming whether the filing was accepted or if corrections are needed. Keep a copy of this confirmation for your records.

Conclusion

Creating an ISF file correctly is crucial for compliance with U.S. Customs regulations. Whether you use a customs broker or file it yourself through an approved software, ensuring accuracy and timeliness can prevent penalties and shipping delays. By following these steps, you can confidently manage ISF filings for your import shipments.
