The Master Bill of Lading (MBL) is a cargo transportation document issued by the shipping company,used to prove the ownership of the goods and the transfer of ownership during the shipping process.This type of bill of lading is usually issued directly by the shipping company to the consignor or its agent,including information such as the name of the goods,quantity,loading port,destination port,and shipping method.Due to its high security,it has been widely used in maritime trade.

In contrast to the ocean bill of lading,there is the "House Bill of Lading" (HBL),which is issued by a freight forwarder.Essentially,the forwarder purchases a certain number of bills of lading from the shipping company and then distributes them to clients.This type of bill of lading is a more profitable option for forwarders,as they can charge additional service fees.However,compared to the Master Bill of Lading (MBL),the HBL is less secure because forwarders can manipulate these documents themselves.Additionally,since the HBL is not issued directly by the shipping company,it may encounter issues in some countries,such as legal recognition during customs inspections.

Although the HBL and MBL have their respective advantages and disadvantages,in maritime trade,the MBL is still widely recognized.Because it is issued directly by the shipping company,it can effectively guarantee the safety of the goods and ensure the effective protection of the ownership of the goods.In addition,the MBL is usually widely used in international trade and can be used for import,trade financing,etc.Therefore,it is very necessary to understand and master the knowledge of the ocean bill of lading (MBL).
