Master Bill of Lading (MBL)
A Master Bill of Lading (MBL) is a transport document issued by the carrier directly to the freight forwarder for a consolidated shipment. It covers the entire cargo moved under one main shipment, even though the goods may belong to multiple shippers. The MBL confirms that the carrier has received the cargo and outlines the terms of carriage. It acts as the primary contract between the carrier and the freight forwarder.
In consolidation scenarios, the MBL sits at the top of the documentation structure. While the carrier issues one MBL to the forwarder, the forwarder may issue multiple House Bills of Lading (HBLs) to individual customers. The MBL contains high-level shipment details, such as ports, vessel or flight information, and the forwarder, who serves as the shipper or consignee. This setup simplifies carrier-level handling and documentation.
The MBL is used for cargo tracking, customs filing, and settlement between the carrier and the forwarder. It also plays a role in liability and claims, as it defines responsibilities at the main shipment level. Accurate MBL details are critical to ensure alignment with HBLs and to avoid clearance or release issues at the destination.
Overall, the Master Bill of Lading is a core document in consolidated freight movements. It enables efficient carrier coordination, supports structured documentation, and ensures that multi-shipper cargo moves smoothly under a single unified transport contract.
