Shipping Requirements for Dry Ice (solid carbon dioxide)
Dry ice (solid carbon dioxide), refrigerated solid, UN 1845, Hazard class 9 (miscellaneous).
Dry ice is classified by DOT and IATA as a "miscellaneous" hazard, which means it is a material that presents a hazard during transportation. Dry ice is characterized as explosion hazard (releases large volumes of carbon dioxide gas), suffocation hazard (carbon dioxide can create an oxygen deficient atmosphere); and contact hazard (as a cryogen, dry ice causes severe frostbite if contacts with skin).
