B/L (Bill of Lading)
Last updated: June 14, 2026
- B/L is the most important document in ocean shipping — it is simultaneously a receipt, a contract, and proof of ownership
- Three release methods: Original B/L (physical document), Sea Waybill (electronic), Telex Release (surrendered at origin)
- B/L accuracy is critical — errors cause customs clearance delays and cargo release problems at destination
B/L (Bill of Lading) is the legal document issued by a carrier to a shipper that details the type, quantity, and destination of goods being carried. It serves three functions simultaneously: a shipment receipt, a contract of carriage, and a document of title — meaning the holder of the original B/L owns the goods.
Chinese: 提单 (Tídān)
Three Functions of a B/L
1. Receipt: The carrier acknowledges they have received the goods described on the B/L in apparent good order. 2. Contract of Carriage: The B/L contains or evidences the terms under which the carrier agrees to transport the goods. 3. Document of Title: The B/L represents ownership of the goods — whoever holds the original can claim the cargo at destination. This is the feature that enables cargo to be sold while in transit.
For China exports, the B/L is typically issued by the carrier (Master B/L or MBL) or by a freight forwarder (House B/L or HBL). Both are valid documents, but for letter of credit transactions, a Master B/L is usually required.
Practical Example
A Qingdao exporter ships 2 x 40ft containers of tires to Dubai under a letter of credit (L/C). The L/C requires 3 original B/Ls. After vessel departure, the carrier issues 3 original B/Ls to Great Hensen, who forwards them to the exporter. The exporter presents them to their bank along with other L/C documents. The bank forwards the documents to the buyer's bank in Dubai. The buyer pays and receives the original B/L, which they present to the carrier's agent at Jebel Ali to take delivery of the tires.
Related Terms
- Incoterms — determine which party arranges and pays for freight
- DDP — delivered duty paid, where seller manages entire chain
- Transit Time — port-to-port duration covered by the B/L
Frequently Asked Questions
What is the difference between an original B/L, sea waybill, and telex release?
Original B/L: a physical paper document that must be presented at destination to release cargo — required when ownership may change during transit. Sea Waybill: a non-negotiable electronic document — cargo is released to the named consignee without presenting an original. Telex Release: the shipper surrenders the original B/L at origin, and the carrier electronically instructs the destination agent to release cargo to the consignee. We explain all three options in our logistics FAQ.
Why is the Bill of Lading called a 'document of title'?
The B/L represents ownership of the goods. Whoever holds the original B/L (properly endorsed) has the legal right to claim the cargo at destination. This allows the cargo to be sold during transit — the seller endorses the B/L to the buyer, who then presents it to the carrier to take delivery. This is the foundation of documentary credit (letter of credit) in international trade.
What information appears on a Bill of Lading?
A B/L includes: shipper name and address, consignee name and address, notify party, vessel name and voyage number, port of loading, port of discharge, container number, seal number, cargo description (quantity, weight, volume), freight terms (prepaid or collect), number of original B/Ls issued, and place and date of issue. Accuracy is critical — errors on the B/L can delay customs clearance and cargo release. We check every detail before submission.
