Example: A freight forwarder shipping goods from multiple suppliers may use an MBL to streamline the process.
A bill of lading is a legal document between a shipper and carrier detailing the type, quantity, and destination of goods.
Acts as a receipt for the goods being transported.
Serves as a contract between the shipper and the carrier.
Can be negotiable or non-negotiable; negotiable bills can be transferred to others.
Example: A bill of lading for a shipment of electronics from a manufacturer to a retailer.
