Let us go deeply in to the above statements with a simple example. A, a freight forwarder acts as a carrier legally accepts cargo from an exporter X agreeing to deliver cargo to Y at New York. A issues bill of lading to X on receipt of goods after necessary export customs formalities. A after receiving goods from X transfers goods to C who is a main carrier of goods. While transferring goods to C, A obtains a bill of lading from main carrier C agreeing to deliver cargo at New York. Here, the bill of lading issued by A to X is called house bill of lading and the bill of lading issued by C to A is called Master Bill of Lading.
