Master Bill of Lading vs House Bill of Lading

What Is the Difference Between a Master and House Bill of Lading?

A Master Bill of Lading (MBL) is issued by the ocean carrier to the freight forwarder for the entire consolidated container shipment. A House Bill of Lading (HBL) is issued by the freight forwarder to each individual shipper whose cargo is part of that consolidation, covering just their specific portion.

How Each Document Works

The MBL governs the legal relationship between the carrier and the forwarder for the whole container, while each HBL governs the relationship between the forwarder and an individual shipper for their specific cargo within it. The consignee named on the HBL deals directly with the forwarder to arrange final delivery, rather than with the ocean carrier itself.

Why This Distinction Matters

Understanding which document applies determines who a shipper needs to contact for shipment status, claims, or delivery arrangements, the ocean carrier only recognizes the MBL and the forwarder as their customer, not individual HBL holders, so most day-to-day communication for consolidated LCL shipments should go through the forwarder.
