A bill of lading (bol) is a legal document that has to be filled out before a freight shipment is hauled. A bill of lading is a legally binding document issued by a carrier to a shipper that details the type, quantity, and destination of the goods being carried. Please enter 10 or fewer pro numbers, pressing enter after each pro number. The surrender of the original straight bill of lading, properly endorsed, is required by transportation lines upon delivery of the freight, in accordance with the terms of the bill of lading. A blank bill of lading or “bol” is an official document issued by a carrier to you (as the shipper) as a contract of carriage of goods.
