What is required as a positive endorsement when shipping hazardous materials to a carrier?

The requirement for a positive endorsement when shipping hazardous materials is the shipper's certification. This certification is a critical document that confirms that the hazardous materials have been properly packaged, labeled, and are in compliance with all relevant regulations. It signifies that the shipper has fulfilled their obligations under the law regarding the safe shipment of hazardous materials, ensuring that the carrier is aware of the nature and risks associated with the materials being transported.

The shipper's certification not only helps to promote safety during transport but also protects the shipper legally by providing a formal acknowledgment of compliance. It is important for carriers to receive this certification to understand their responsibilities and ensure that they handle the hazardous materials safely throughout the transportation process.
