Definition
A bill of lading (B/L) is a legal document issued by a carrier to a shipper that serves three functions: it acts as a receipt confirming the goods were loaded onto the vessel, a contract of carriage outlining the terms of transport, and a document of title that can be used to transfer ownership of the goods.
Why It Matters for Importers
The bill of lading is required for customs clearance. Without it, your customs broker cannot file an entry with CBP, and the shipping line will not release your cargo. It is one of the first documents your broker will request when processing a shipment.
Errors on the bill of lading — such as incorrect consignee information, wrong container numbers, or inaccurate descriptions of goods — can delay customs clearance and trigger additional scrutiny from CBP. Getting the B/L right at origin prevents costly corrections at destination.
Key Details
- Master vs. House B/L: A master bill of lading is issued by the ocean carrier. A house bill of lading is issued by a freight forwarder. Both may exist for the same shipment.
- Negotiable vs. Non-negotiable: A negotiable (original) B/L transfers title and must be surrendered to pick up cargo. A non-negotiable (sea waybill) does not transfer title.
- ISF filing: The bill of lading number is used to file the Importer Security Filing (ISF), which must be submitted at least 24 hours before the vessel loads.
- Telex release: An electronic release that eliminates the need to present original paper bills of lading at destination.
