USA ISF Filing Guide: How to Complete the Importer Security Filing Process
International ocean shipping to the United States involves several customs and security requirements. One of the most important is the Importer Security Filing (ISF), commonly known as the 10+2 filing. It provides U.S. Customs and Border Protection (CBP) with important shipment information before cargo is loaded onto a vessel bound for the United States.
A properly prepared ISF can help importers maintain compliance and reduce the risk of delays, cargo holds, or penalties caused by missing or inaccurate information. Understanding when to file, what information is required, and who is responsible can make the import process easier to manage.

What Is ISF Filing?
The Importer Security Filing (ISF) is a U.S. Customs and Border Protection requirement for applicable ocean shipments entering the United States. It is often referred to as the 10+2 rule because the importer provides ten data elements, while the carrier provides two additional pieces of information.
The filing generally needs to be submitted at least 24 hours before the cargo is loaded onto the vessel at the foreign port. Depending on the shipment, information may include the seller, buyer, importer of record, consignee, manufacturer, HTS classification, container stuffing location, and ship-to party.
Because the information is used by CBP for advance cargo security and risk assessment, accuracy and timely submission are important parts of the process.
Who Is Responsible for ISF Filing?
The importer of record is generally responsible for ensuring that the required ISF information is submitted correctly and on time. An importer may complete the filing directly or authorize a licensed customs broker or another qualified agent to submit the information on their behalf.
Suppliers, manufacturers, freight forwarders, and carriers may provide important shipment information needed for the filing. However, each party has a different role, and the importer should coordinate with the relevant parties to make sure the information provided for the ISF is complete and accurate.
How to File ISF: 5 Essential Steps
The ISF process can be organized into five practical steps. Following a clear process helps importers collect the necessary information and complete the filing within the required timeframe.
Step 1: Collect Shipment Information
Before starting the filing, collect the information required for the shipment. This may include the seller and buyer details, importer information, consignee information, manufacturer or supplier details, product description, HTS information, and other relevant cargo data.
The quality of the information provided by suppliers and logistics partners can directly affect the accuracy of the ISF submission.
Step 2: Select a Filing Method
Importers can determine whether to handle the ISF filing themselves or work with a licensed customs broker or authorized service provider.
Using an experienced filing partner may help simplify the process, especially when an importer handles multiple shipments or works with suppliers in different countries.
Step 3: Submit the ISF Before Vessel Loading
Once the required information has been collected and checked, the ISF should be submitted to CBP within the required timeframe. For applicable ocean shipments, the filing is generally required at least 24 hours before the cargo is loaded onto the vessel.
Shipment information such as the bill of lading, container details, cargo information, and estimated transportation details should be reviewed carefully before submission.
Step 4: Monitor CBP Responses
After submitting the ISF, continue monitoring communications related to the filing. If additional information, clarification, or corrections are requested, the importer or its authorized agent should respond promptly.
Keeping communication open between the importer, customs broker, freight forwarder, supplier, and carrier can help resolve information issues more efficiently.
Step 5: Continue Monitoring the Shipment
After the filing has been completed, importers should continue tracking the shipment and keep relevant ISF records. If there are customs questions, examinations, holds, or other issues, the importer can work with its customs broker or logistics provider to address them.
A complete filing process does not end immediately after submission. Ongoing communication and record keeping are also important parts of import compliance.
Responsibilities of Importers and Other Parties
Importer
The importer is responsible for coordinating the filing and providing accurate shipment information. The importer should also make sure that the ISF is submitted within the required timeframe and respond to relevant communications.
Customs Broker
A customs broker can assist with preparing and submitting the ISF, interpreting customs requirements, communicating with CBP, and handling corrections when necessary.
Freight Forwarder
Freight forwarders often coordinate transportation arrangements and exchange shipment information between importers, suppliers, carriers, and customs brokers.
Carrier
The carrier provides additional transportation-related information required under the applicable filing requirements, including relevant vessel, voyage, or cargo information.
Supplier or Manufacturer
Suppliers and manufacturers can support the filing process by providing accurate product descriptions, manufacturer information, quantities, and other shipment details requested by the importer or customs broker.
Common ISF Filing Mistakes
Several issues can make the ISF process more difficult. Importers should pay particular attention to the following areas:
1. Incorrect Shipment Information
Incorrect product descriptions, quantities, party information, or tariff classifications can create inconsistencies in the filing.
2. Missing the Filing Deadline
Submitting information too late can create compliance issues and may contribute to shipment delays or penalties.
3. Poor Communication
ISF information often comes from several parties. Delays in receiving information from suppliers, forwarders, or carriers can affect the filing process.
4. Incorrect HTS Classification
The tariff classification should be reviewed carefully to help ensure that the information submitted for the shipment is consistent with the applicable classification.
5. Incomplete Party Information
Importer, consignee, manufacturer, seller, buyer, and ship-to information should be checked before submission.
ISF Filing and Different Transportation Modes
ISF requirements are primarily associated with applicable ocean cargo entering the United States. Other transportation modes, such as air, rail, and truck transportation, may involve different customs and cargo reporting requirements.
Ocean Freight
For ocean shipments, the filing process focuses on providing required cargo and supply-chain information before the goods are loaded onto the vessel.
Air Freight
Air cargo generally follows different customs reporting procedures. Importers should confirm the applicable requirements for their specific shipment rather than assuming that ocean ISF procedures apply.
Rail and Truck Transportation
Rail and truck shipments may involve other customs entry, in-bond, or cargo reporting procedures depending on how the goods enter or move through the United States.
For this reason, importers should confirm the specific requirements with their customs broker or logistics provider based on the actual transportation method.
What Happens After ISF Filing?
Submitting the ISF is an important step, but importers should continue monitoring the shipment after filing.
Review Filing Confirmation
Keep the filing confirmation or relevant records provided by the filing system or customs broker.
Monitor Customs Communication
Watch for any requests for additional information, corrections, or clarification.
Track the Shipment
Continue monitoring vessel schedules, estimated arrival times, and other transportation updates.
Respond to Holds or Examinations
If CBP places a shipment on hold or selects it for examination, work with the appropriate customs or logistics professionals to address the issue.
Keep Records
Maintain ISF submissions, communications, shipping documents, and related records for future reference and compliance needs.
ISF Compliance and Filing Solutions
For importers managing frequent shipments, an organized filing process can make it easier to collect information, monitor deadlines, and maintain accurate records.
Automated filing tools and professional customs services may also help reduce manual data entry and improve communication between importers, logistics providers, and customs professionals.
When choosing a filing solution, importers should consider factors such as shipment volume, data management, filing requirements, system integration, and customer support.
