There are two ways of endorsement: registered endorsement and blank endorsement.
(1) A registered endorsement refers to writing the name of the endorser (the person written after the order) and the name of the endorsee on the back of the bill of lading;
(2) A blank endorsement only indicates the name of the endorser, not the name of the transferee of the bill of lading. A blank endorsed instruction bill of lading has the same effect as a bearer bill of lading, and the carrier has the obligation to hand over the goods to the person who presents the bill of lading and requests delivery.
