Dry ice is regulated as a hazardous material if shipped by air or water. Contact Shipping for any shipments that include dry ice (x5094, x4388, or shipping@lbl.gov). Special labeling on the package is required.
Dry ice is not regulated as a hazardous material when simply transported in a vehicle. Do not place dry ice inside outer packaging that is gas-tight. Transport packages with dry ice in the bed of a pickup truck if feasible. If packages with dry ice must be transported inside a vehicle, roll down all the windows during transport and minimize the amount of time the dry ice is inside the vehicle.
