The Bill of Lading serves as the central contract of carriage between shipper and carrier, as defined in the CLT "Dispatch and Tracking" module. It documents shipment details-such as shipper, consignee, commodity, weight, and handling instructions-and must be signed upon receipt. The consignee's signature confirms acceptance, completing the shipment lifecycle. It simultaneously acts as a receipt for goods, evidence of a contract, and a title document. The packing list itemizes contents; the purchase order initiates procurement; the carrier requisition is not an official transport form. Thus, the Bill of Lading uniquely meets all required delivery confirmation criteria.
