The bill of lading (B/L or BOL) is the single most important document in international sea freight. It is issued by the shipping line to the shipper and serves three simultaneous legal functions: it is a receipt for the cargo, a contract of carriage between the shipper and the carrier, and a document of title — meaning whoever holds the original B/L has the legal right to claim the goods at destination.
What Information Is on a Bill of Lading?
A standard bill of lading contains: shipper details (exporter), consignee details (importer), notify party (usually the customs broker or freight forwarder at destination), vessel name and voyage number, port of loading and port of discharge, container number(s) and seal number(s), cargo description, weight and volume, freight payment terms (prepaid or collect), and the B/L number itself — the unique reference you use to track the shipment.
Original B/L vs Telex Release vs Seaway Bill
An Original B/L is a physical document — the buyer must surrender the original to the shipping line at destination to take possession of the cargo. This is the most secure but slowest method. A Telex Release (also called Express Release) means the shipper surrenders the originals at origin and instructs the line to release the cargo at destination without a physical document — faster and more common for trusted trade relationships. A Sea Waybill is a non-negotiable transport document — the consignee named on it can collect the goods simply by proving their identity, without any document. Seaway bills are common in high-volume trade lanes where cargo arrives before documents.
Master B/L vs House B/L
A Master B/L (MBL) is issued by the shipping line to the freight forwarder. A House B/L (HBL) is issued by the forwarder to the actual shipper. When a forwarder consolidates multiple small shipments (LCL cargo) into one container, there is one MBL covering the whole container and individual HBLs for each shipper. For tracking purposes: the MBL number works on the shipping line's tracking portal; the HBL number works on the forwarder's system.
How to Track Using Your B/L Number
Enter your B/L number in the Trackora sea freight tracker. Trackora will either retrieve the full event timeline directly via the carrier's API, or generate a pre-filled direct link to the shipping line's official tracking portal — whichever gives the most accurate data for that carrier. You can track by container number or B/L number interchangeably on Trackora.
Common B/L Mistakes to Avoid
Errors on a B/L are costly and time-consuming to correct. The most common mistakes: wrong consignee name or address (can prevent customs clearance), incorrect cargo description (can trigger inspection), wrong weight or volume (affects freight charges and customs duty), and missing notify party details (delays final-mile delivery notification). Always verify the draft B/L from your forwarder before it is finalised — amendments after the vessel departs usually incur fees.
