House B/L vs Master B/L
Who issues which, when you need both, and what happens when they don't match

House B/L (HBL)
Issued by NVOCC or freight forwarder to the shipper. Your contract with your client.
Master B/L (MBL)
Issued by the ocean carrier to the NVOCC or forwarder. The carrier's contract with you.
