The Importer Security Filing (ISF), also known as “10+2,” is a mandatory U.S. Customs requirement for ocean imports. Filing it correctly, and on time, is crucial for smooth cargo clearance and avoiding penalties. Here’s a quick guide and software solution overview.

What Is ISF?

ISF requires importers to submit 10 data elements about the cargo (and 2 from the carrier) to U.S. Customs and Border Protection (CBP) at least 24 hours before vessel loading at the foreign port.

Key Compliance Requirements

Filed by the Importer of Record or their U.S.-based agent

Requires details like shipper, consignee, container stuffing location, HTS codes, etc.

Inaccurate or late filings may result in $5,000 fines per violation

Must match the Bill of Lading and manifest data

ISF Software Solutions

Using a dedicated ISF software or partnering with a Customs Broker simplifies the process:

Real-time CBP connectivity

Data validation & error checks

Audit logs for recordkeeping

Integration with AMS & ACE systems

Popular tools include:

Customs broker platforms

Freight forwarding TMS

Standalone ISF e-filing tools

Best Practices

File early, even before final cargo confirmation

Automate data entry to reduce manual errors

Keep all documents aligned (ISF, B/L, Commercial Invoice)

Using the right software ensures your Importer Security Filing is timely, accurate, and fully compliant, keeping your supply chain on track.

Importing to the U.S. and wondering who is responsible for filing the ISF? The Importer Security Filing (ISF), also known as “10+2,” is a U.S. Customs requirement for ocean shipments, and timely filing is crucial. Here's who handles what:

1. The Importer of Record The primary responsibility lies with the importer of record. This can be the buyer, consignee, or owner of the goods. They’re accountable for ensuring ISF is filed accurately and on time.

2. U.S.-Based Agent If the importer is not U.S.-based, they must appoint a U.S. agent (often a customs broker or freight forwarder) to file the ISF on their behalf.

3. Customs Broker Many importers authorize a licensed customs broker to file the ISF. Brokers handle the paperwork, transmit data through CBP’s ACE system, and ensure compliance.

4. Freight Forwarder or NVOCC Forwarders may assist with providing shipment details (like container stuffing location and consolidator info), but they don’t usually file unless explicitly authorized.

5. Carrier (Limited Role) Ocean carriers are responsible for filing the vessel manifest (not the ISF). However, they do provide the “2” data elements like vessel stow plan and container status messages.

Deadline Reminder: ISF must be filed at least 24 hours before cargo is loaded onto the vessel bound for the U.S. Late or inaccurate filings can lead to penalties up to $5,000.

In short, the importer is responsible, but filing is often delegated to a trusted U.S. agent or broker.
