What is a Bill of Lading (B/L)? [Logistics Terminology]

What is a Bill of Lading (B/L)?

A Bill of Lading (B/L) is one of the most critical ocean transport documents in international trade. It is issued by the shipping line once the exporter delivers the goods to the carrier, serving as evidence of the contract of carriage between the shipper and the shipping line. It is widely regarded as the most important document in maritime transport and is commonly referred to as a “B/L”.

The terms and conditions printed on both the front and back of the Bill of Lading constitute the “Contract of Carriage” defining the responsibilities and liabilities of the carrier. These contents are governed by international conventions; in domestic legislation, the Law on International Carriage of Goods by Sea is enacted as a specialized branch of Commercial Law.

A Bill of Lading possesses the characteristics of a master’s receipt for goods, a receipt for goods in exchange for delivery, a valuable security, and a negotiable instrument. Since it represents the goods listed therein (in the form of a document of title), it enables the secure execution of international transport across multiple involved parties.

The Roles of a Bill of Lading (B/L)

The Bill of Lading is issued by the shipping line at the port of loading. Its role evolves depending on the timing and the position of the parties involved.

1. Valuable Security
The holder of a Bill of Lading is not necessarily the owner of the goods. It functions as a security certifying the right to demand cargo delivery from the carrier. The B/L is the documentary evidence to claim: “Please deliver the goods to me.”

2. Receipt of Goods
The Bill of Lading is issued when the shipping line receives the cargo. It serves as a receipt confirming that the shipping line has taken possession of the goods.

3. Contract of Carriage
For shipping lines, shippers, or freight forwarders, the Bill of Lading acts as a contract of carriage, proving that a transport agreement has been concluded between the carrier and the shipper (or the freight forwarder).

4. Document for Cargo Release
For the consignee, the Bill of Lading is an essential document required to receive the goods at the port of discharge.

Contents of a Bill of Lading (B/L)

Bill of Lading forms vary depending on the issuing shipping line, but the main items typically contain similar information.

Shipping Line Name
B/L Number (B/L No.)
Shipper
Consignee
Notify Party
Place of Receipt
Ocean Vessel
Port of Loading
Port of Discharge
Place of Delivery
Description of Goods
Number of B/L copies issued
Place and Date of B/L issue
Signature of the Carrier
On Board Date & Vessel Confirmation

If there are any typographical errors on the Bill of Lading, only the shipping line at the port of loading can make corrections, which can be time-consuming if discovered by the importer later. To ensure smooth trade transactions, please double-check all contents carefully.

Types of Bills of Lading (B/L)

Bills of Lading are classified based on loading methods, cargo conditions, consignee information, etc.

1. Original B/L
An Original B/L is a vital document used in trade transactions between sellers and buyers. Typically, an Original B/L is issued in a set of three. It is sent from the exporter to the importer via courier services; however, to mitigate the risk of loss, these three originals are often sent separately in different mailings.

2. Surrendered B/L
A Surrendered B/L is a bill of lading that the shipping line has collected from the exporter at the port of loading. The exporter’s copy will be marked “Surrendered.” Since the Original B/L has already been submitted to the shipping line at the port of departure, the importer can claim the goods at the port of discharge without the original document, using only the Surrendered B/L. This method is commonly used when the cargo arrives before the documents or for imports from neighboring countries.

3. Sea Waybill
A Sea Waybill is a receipt for goods issued by the shipping line to the shipper and serves as evidence of the contract of carriage, but it is not a document of title (non-negotiable). It is also referred to as a unit waybill.
When shipping via Sea Waybill, the importer can receive the goods at the port regardless of whether the payment has been settled. Compared to an Original B/L or a Surrendered B/L, a Sea Waybill allows for immediate cargo release upon issuance, offering the advantage of reduced delivery time. However, the exporter faces the risk of non-payment. Therefore, Sea Waybills are typically used in long-term, high-trust trade relationships or between parent companies and subsidiaries within the same corporation.

Summary

A Bill of Lading (B/L) is a vital trade document issued by a shipping line upon receiving cargo from an exporter. This document serves as evidence of the Contract of Carriage, with terms and conditions detailed on both the front and back. The B/L functions as a document of title, a receipt of goods, a transport contract, and a claim document, playing a crucial role in commercial transactions. A B/L includes essential information such as the shipping line’s name, shipper, consignee, description of goods, etc., and must be checked thoroughly to avoid errors that cause delays. There are three main types of B/L: Original B/L, Surrendered B/L, and Sea Waybill, each with its own characteristics and conditions of use. Original B/Ls are typically issued in a set of three; a Surrendered B/L allows for cargo release at the destination port without the original document; and a Sea Waybill facilitates rapid delivery but carries payment risks for the exporter.
