A Bill of Lading (B/L) is a legal document issued by a carrier or its agent to a shipper that serves three critical functions in commercial transportation: it acts as a receipt for goods delivered to the carrier, a contract of carriage specifying the terms and conditions of transport, and a document of title that can be used to transfer ownership of the goods while they are in transit. The Bill of Lading is one of the oldest and most important documents in commercial law, with roots in medieval maritime trade.

Domestic bills of lading for overland transport in the United States are governed by the Carmack Amendment to the Interstate Commerce Act (49 U.S.C. Section 14706), which establishes a uniform national liability regime for interstate motor carriers and rail carriers. Under the Carmack Amendment, a carrier is strictly liable for loss, damage, or delay to goods it transports, subject to limited exceptions for acts of God, public enemy, authority of law, acts of the shipper, and inherent vice of the goods. Ocean bills of lading for international maritime shipments are governed by the Carriage of Goods by Sea Act (COGSA, 46 U.S.C. Sections 30701-30707), which implements the Hague Rules and limits carrier liability to $500 per package or customary freight unit unless a higher value is declared.

Bills of lading come in several forms with different legal effects. A straight (non-negotiable) bill of lading consigns goods to a named consignee and cannot be transferred by endorsement. An order (negotiable) bill of lading is made to the order of the shipper or a named party and can be endorsed and transferred, functioning as a negotiable document of title under UCC Article 7 (Sections 7-101 through 7-603). The distinction determines whether the goods can be traded while in transit and affects the rights of banks providing documentary letters of credit.

A manufacturer is shipping finished goods to a distributor or retailer via a trucking company and needs an official receipt documenting what was shipped, when, and in what condition the goods were delivered to the carrier. An importer is receiving a container of goods from an overseas supplier and the ocean carrier issues a bill of lading as part of the international shipping documentation.

A shipper using a freight broker or third-party logistics provider needs to document the chain of custody for goods passing through multiple carriers or warehouses during transit. A seller under a letter of credit arrangement must present a clean bill of lading (one showing no damage or discrepancies) to the issuing bank to receive payment under the documentary credit.

A company is filing a freight claim for goods lost, damaged, or delayed during transit and needs the original bill of lading as proof of the shipment and the goods' condition at the time of tender to the carrier. A warehouse operator is receiving goods for storage and issues a warehouse receipt, which functions similarly to a bill of lading as a document of title under UCC Article 7.

An international trader is using a negotiable bill of lading to transfer ownership of goods in transit to a buyer or financing bank, with the bill serving as collateral for trade finance arrangements.

The shipper's (consignor's) full legal name, address, and contact information must be stated, along with the consignee's (receiver's) name and destination address. For order bills of lading, the "notify party" who should be contacted upon arrival must also be identified.

The goods description must be detailed and accurate, including the number of packages, type of packaging (pallets, cartons, drums, containers), the weight (gross and net), dimensions, commodity description, freight class (for LTL shipments under the National Motor Freight Classification system), and any special handling requirements (temperature-controlled, hazardous materials, fragile).

For shipments involving hazardous materials, the bill of lading must comply with Department of Transportation (DOT) regulations under 49 C.F.R. Parts 171-180, including the proper shipping name, hazard class, UN identification number, packing group, and emergency contact information.

Freight charges and payment terms must specify whether the shipment is prepaid (shipper pays) or collect (consignee pays), the applicable freight rate, and any accessorial charges such as liftgate service, inside delivery, or detention. The declared value of the goods should be stated if the shipper wants to increase the carrier's liability above the default limits.

The carrier's standard terms and conditions, which are typically printed on the reverse side of the bill of lading or incorporated by reference, govern the carrier's liability limitations, claims procedures, time limits for filing claims (typically 9 months for loss or damage under 49 C.F.R. Section 370.3), and the shipper's obligations regarding packaging and loading.

The document must be signed by both the shipper (or their agent) and the carrier's driver or agent upon pickup. The condition of the goods at the time of tender should be noted. Any exceptions, damage, or discrepancies observed during loading must be noted on the bill of lading to preserve the shipper's right to file a claim.
