The close message finalizes the related parent BL. For FCL, the close message will close the Carrier’s MBL. Moreover, the Canada Border Services Agency (CBSA) demands that a consolidated HBL must be on file to close out a consolidated HBL, or the close message will be declined. Nevertheless, it is not required for the carrier’s MBL to be on file before sending the close message that closes out the carrier’s MBL.
