Who Is Responsible For Filing The ISF? Know The Key Roles
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.
