Which document is used for transporting chemicals over roads and highways?

The bill of lading is the correct document used for transporting chemicals over roads and highways. This document serves as a legally binding contract between the shipper and the carrier, detailing the type, quantity, and destination of the chemicals being transported. It acts as a receipt for the goods and provides crucial information that ensures safe and compliant transportation. The bill of lading also helps to regulate transport, ensuring that all parties understand their responsibilities regarding the shipment of hazardous materials.

In contrast, the shipping manifest typically lists all cargo being transported but does not function as a contract between parties. A freight invoice is related to the billing of services provided by a carrier, while a cargo receipt is issued upon delivery as proof of receipt; neither serves the same comprehensive purpose as a bill of lading in the context of shipping chemicals.
