The ISF Form is a mandatory filing required by U.S. Customs and Border Protection (CBP) for ocean shipments entering the United States. It’s often called the “10+2 filing” because it collects detailed information about both the cargo and the carrier.

Key Elements in an ISF Form

Importer details – who’s responsible for the goods.

Consignee information – final receiver of the shipment.

Seller & buyer details – trade parties involved.

Manufacturer or supplier info – origin of the goods.

Country of origin & HTS codes – product classification.

Container stuffing location & consolidator – for cargo handling transparency.

Top Practices for Compliance

✅ File early – at least 24 hours before cargo is loaded at the origin port. ✅ Double-check accuracy – incorrect data can lead to penalties. ✅ Work with a reliable customs broker or forwarder – they ensure filings are handled smoothly. ✅ Keep records organized – documentation consistency helps avoid delays.

Submitting the ISF Form correctly isn’t just about avoiding fines, it’s about ensuring your supply chain runs without disruptions. A small mistake can cause delays at U.S. ports, while proper filing builds efficiency and trust.
