If you are involved in shipping or logistics, you've probably heard of a master bill of lading and a house bill of lading. But if you're like many, you might not understand how they're different.
What is the difference between a house bill of lading and a master bill of lading?
A house bill of lading is issued by a non-vessel-operating common carrier (NVOCC) to its customer and documents the transportation agreement between those parties. A company may be licensed as both an NVOCC and an ocean freight forwarder, but it issues the house bill in its capacity as an NVOCC.
A master bill of lading is issued by the vessel-operating ocean carrier to the party that booked the cargo—often the NVOCC or, in a direct booking, the shipper. It documents the carrier’s transportation agreement with that booking party.
The same cargo may therefore be covered by both documents: the HBL covers the shipper-to-NVOCC relationship, while the MBL covers the NVOCC-to-ocean-carrier relationship. One MBL may be connected to one or several HBLs, but consolidation is not required.
What Is a Bill of Lading?
Before we explain more about the difference between these two types of bill of lading, it is important to understand what a bill of lading is. A bill of lading is a document that serves three primary purposes:
- Receipt for the goods. It acknowledges the transfer of cargo from one party to another.
- Evidence of the contract of carriage. A contract is a written agreement that one party will move cargo to a particular destination on behalf of another party. In the absence of a separate contract, the bill of lading assumes the role of a contract of carriage by default.
- Potential document of title. In the context of law, title means ownership. A bill of lading marked "negotiable" indicates evidence of title and can be transferred from one party to another any number of times; this enables cargo to be transferred from one transportation company to another during its journey to its destination. A bill of lading marked "non-negotiable" does not indicate evidence of title and thus it cannot be transferred.
A bill of lading is just one of the many export documents you'll need for your international shipments and one that you can create with Shipping Solutions. You'll find a more in-depth overview of bills of lading in the article What is a Bill of Lading: 3 Things You Need to Know, or watch this video:
As you can see, a bill of lading can serve multiple functions, and there are different types of bills of lading. So, what is the difference between a house bill of lading and a master bill of lading?
What Is a House Bill of Lading?
A house bill of lading (HBL) is issued by a non-vessel-operating common carrier (NVOCC) to the exporter, shipper or other customer that hired it to transport the goods. It acknowledges receipt of the cargo and documents the transportation agreement between the customer and the NVOCC.
A company may operate as both an ocean freight forwarder and an NVOCC, but it issues the HBL in its capacity as an NVOCC. The NVOCC then books cargo space with carriers.
An HBL is more than a simple pickup receipt. It may serve as evidence of the contract of carriage and, depending on its form and terms, may also function as a document of title.
What Is a Master Bill of Lading?
A master bill of lading (MBL) is issued by the vessel-operating common carrier or ocean shipping line to the party that booked the transportation. When an NVOCC arranged the shipment, the NVOCC is generally the shipper or booking party shown on the MBL. When an exporter books directly with the ocean carrier, the carrier’s bill may be the only ocean bill of lading and there may be no HBL.
House Bill of Lading vs. a Master Bill of Lading: An Example
Here's how both types of bills of lading might be used in an international shipment:
Exporting Company A needs to ship four crates of solid gold from the United States to Zimbabwe. Exporting Company A submits a request to Freight Forwarding Company to arrange the shipment. Freight Forwarding Company picks up the crates from Exporting Company A’s warehouse. At this point, Freight Forwarding Company issues a house bill of lading to Exporting Company A. The house bill of lading serves as a receipt to confirm they’ve picked up the goods.
Freight Forwarding Company compares rates and availability of potential carriers and identifies Carrier Company as the right choice to move the shipment of gold to Zimbabwe. But they also identify this same company as the right choice to move other shipments from other exporters to Zimbabwe, such as six boxes of school supplies from Exporting Company B and eight pallets of hemp fiber textiles from Exporting Company C.
Since all three shipments are destined for Zimbabwe, Carrier Company picks them up from Freight Forwarding Company and consolidates them. Instead of issuing three separate bills of lading, Carrier Company issues a single master bill of lading to Freight Forwarding Company that serves as a receipt to confirm they’ve picked up all the goods for delivery to their destination and a contract for the carriage.
In this example, three HBLs describe the individual customer shipments, while the MBL describes the shipment booked by the NVOCC with the ocean carrier. If the manufacturer had booked directly with the ocean carrier, there might be an MBL or carrier bill but no HBL.
| Feature | House Bill of Lading (HBL) | Master Bill of Lading (MBL) |
|---|---|---|
| Issued By | NVOCC, including a freight forwarder acting in its capacity as an NVOCC | Vessel-operating carrier or ocean shipping line |
| Issued To | The NVOCC’s customer, usually the exporter or shipper | The party that booked the carrier space, often an NVOCC but sometimes the exporter |
| Function | Receipt for goods from shipper; may serve as contract of carriage | Receipt for consolidated goods; contract of carriage |
| Covers | One shipment from one exporter | Cargo moving under the carrier’s bill or booking; it may be associated with one or multiple HBLs |
| Used For | Tracking shipment between shipper and freight forwarder/NVOCC | Tracking shipment between NVOCC and carrier |
| Title of Goods | May or may not serve as document of title | Can serve as document of title if marked negotiable |
In Summary
A house bill of lading and a master bill of lading are not competing versions of the same document. They document two different layers of an international ocean shipment.
The HBL is issued by an NVOCC to its customer and covers the transportation relationship between those parties. The MBL is issued by the vessel-operating carrier to the party that booked the cargo and covers the carrier-level transportation relationship.
A shipment may have both documents, particularly when an NVOCC is involved. It may also have only a carrier-issued ocean bill when the exporter books directly with the ocean carrier.
