What is a Bill of Lading (B/L) and why does it matter for importers?

A Bill of Lading (B/L or BOL) is the most important document in ocean freight. It serves three legal functions simultaneously: a receipt from the carrier confirming the goods have been loaded on board; a contract of carriage defining the terms of transportation; a document of title that proves ownership of the goods. There are two main types relevant to importers: Ocean B/L (Master B/L) — issued by the shipping line to the freight forwarder; House B/L — issued by the freight forwarder to the shipper, used in LCL (groupage) shipments. An original B/L is required to collect the cargo at the destination port — without it, the carrier will not release the goods. If you are buying under a Letter of Credit (L/C), the bank requires the B/L as the key document proving shipment. Electronic equivalents (Sea Waybill, eSWB) are increasingly common and do not require surrender of an original paper document. Practical tip: as soon as the vessel departs, request the draft B/L from your forwarder and check that all details (shipper, consignee, description of goods, HS code, quantity, weight) match your documents. Errors on the B/L are expensive to correct once the vessel is at sea.
