The House Bill Close Message (HBCM) is an important document in the international trade and transportation industry. It serves as a confirmation that all the individual shipments in a consolidated shipment have been properly consolidated into a single shipment and that all the necessary documentation has been submitted to the appropriate authorities.

The HBCM is used by freight forwarders to transmit information to customs authorities and other stakeholders about the consolidated shipment. It contains information about the shipper, consignee, and the cargo being transported. It also includes details about the freight forwarder, the carrier, and the transportation mode.

The HBCM helps ensure that all the necessary documentation is in place and that the shipment is compliant with all applicable regulations. It also helps to reduce the risk of errors, delays, and other issues that can occur during the transportation process. Overall, the HBCM is an essential document that plays a critical role in facilitating international trade and ensuring that shipments are processed efficiently and accurately.
