Three functions
- Receipt: confirms the carrier received the described cargo on board, in the stated apparent condition and quantity.
- Evidence of the contract of carriage: records the terms on which the carrier agreed to transport the cargo.
- Document of title: in negotiable form, the holder can claim the goods and can transfer that right by endorsing and delivering the document.
The bill of lading date
The B/L date usually marks when loading completed, and in many contracts it anchors the pricing period, for example an average of the benchmark around that date. It also starts time running for several contractual and documentary deadlines, so the date is treated as a key reference point.
Negotiable vs straight bills
A negotiable (to order) bill of lading can be transferred to successive holders, which is what lets cargoes be sold while still at sea. A straight bill names a single consignee and is not transferable in the same way. The form used affects how title moves and how a bank controls the goods under a letter of credit.
The legal framework
Carriage of goods by sea, including the carrier's responsibilities and limits, is commonly governed by international conventions such as the Hague-Visby Rules, as incorporated into the applicable national law and the carriage contract.
