Understanding Importer Security Filing (ISF) Online

If you import goods into the United States by ocean vessel, you may have heard about ISF, or Importer Security Filing, sometimes known as “10+2.” Filing this document online is a critical task that helps U.S. Customs and Border Protection (CBP) ensure cargo safety and security before your goods arrive. Let’s break down exactly what ISF is, how to file it online, and everything you need to know to stay compliant and avoid costly mistakes.

What is Importer Security Filing (ISF)?

Importer Security Filing (ISF), also called “10+2,” is a mandatory electronic filing requirement for importers shipping goods into the U.S. by ocean. The “10” represents 10 data elements importers must provide about the shipment, while the “2” refers to 2 data elements required from carriers. The ISF must be submitted to CBP at least 24 hours before goods are loaded onto the vessel overseas.

The main purpose: ISF allows customs officers to assess the security risk of incoming shipments and helps smooth the flow of international trade while keeping the country safe.

How to File ISF Online

Filing ISF online isn’t just possible—it’s the most popular and efficient way to get it done. Here’s an easy-to-follow guide to help you navigate the process.

1. Register with a Filing Platform or Customs Broker

First, importers must register with an online ISF filing service, use a licensed customs broker, or have their in-house logistics team access the U.S. CBP’s Automated Broker Interface (ABI).

• ISF Filing Services: Many companies provide user-friendly online ISF platforms. Examples include RocketISF, Turbo ISF, and ImporterSecurityFiling.com. These platforms simplify filing—with step-by-step instructions and customer support.

Before you start, make sure you have all the necessary details. Here are the main data elements importers need to provide:

1. Seller Name and Address
2. Buyer Name and Address
3. Importer of Record Number
4. Consignee Number
5. Manufacturer Name and Address
6. Ship-to Name and Address
7. Container Stuffing Location
8. Consolidator (Stuffer) Name and Address
9. Importer Security Filing Number
10. Commodity Harmonized Tariff Schedule (HTSUS) Number

Tip: Gather this information early! You’ll often need to coordinate with suppliers, manufacturers, or freight forwarders abroad.

3. Initiate the Online Filing

• Log in to your chosen ISF filing platform or communicate with your customs broker.
• Enter the required data elements in the online form.

Common Questions and Answers

Frequently Asked Questions (FAQs)

1. What happens if I file ISF late or not at all?
Failure to file ISF on time, or not filing it at all, can result in fines up to $5,000 per violation. Late filings often lead to cargo holds at the port, inspection delays, or even refusal of entry.

2. Who is responsible for filing ISF—me or my supplier?
The ISF must be filed by the U.S. importer or their authorized agent, such as a licensed customs broker. Overseas suppliers can provide the data, but you (the importer) are ultimately responsible for timely and accurate submission.

3. Can I amend ISF information after it’s filed?
Yes. If you discover an error or your shipment details change, you can (and should) file an amendment using your online platform, broker, or ABI connection, up until the cargo arrives in the U.S.

4. Do I need to file ISF for air or land shipments?
No. ISF (10+2) only applies to cargo shipped to the U.S. by ocean vessel. Air, truck, and rail shipments have other customs requirements but are not covered by ISF regulations.

5. How much does online ISF filing cost?
Online ISF filing fees vary based on service provider and shipment complexity. On average, expect to pay between $20 and $50 per submission. Using a full-service customs broker may cost more, but often includes additional compliance services.
