What is hazardous materials accessorial?

Hazardous materials are articles that exhibit hazardous characteristics under certain conditions. These goods are classified by UN/ICAO and are assigned a UN #, Proper Shipping Name and Packing Instruction. These goods must be accompanied by a Dangerous Goods certificate, which is a document describing the nature of the hazard and edged in red and white chevrons.

ExFreight does not accept hazardous goods for transport by air, however, you can ship them via truck or ocean services.

The hazardous materials accessorial is to be selected when you are shipping a shipment that is considered hazardous.
