A House Bill of Lading (HBL) is the bill of lading issued by an NVOCC or freight forwarder to the underlying shipper — the actual cargo owner — for goods consolidated into a larger shipment.
The HBL names the real shipper and the real consignee (or ultimate consignee) and reflects the commercial terms between them. It sits beneath a Master Bill of Lading issued by the ocean carrier to the consolidator.
In an LCL shipment, dozens of HBLs may sit under a single MBL — each cargo owner getting their own document for their portion of the container.
For U.S. inbound shipments, the NVOCC files HBL data into AMS under the AMS 24-Hour Rule. The ocean carrier files the MBL separately. Both filings must match in vessel, voyage, and bill-of-lading number references or CBP issues a "Bill on Hold."
The HBL is what the importer or its customs broker actually uses to file the entry — the MBL is largely invisible to the end customer.
