Requirements for Shipping Dry Ice [IATA PI 904]
When dry ice is shipped by air and water it is regulated as a dangerous good. The IATA regulations give some regulatory relief to shipments of dry ice by air. The IATA Dangerous Goods Regulations require that dry ice be packaged in accordance with packing instruction 904. It is allowed to be vented to prevent a build up of pressure that could rupture the packaging. Arrangements must be made between the shipper and the operator to ensure that ventilation safety procedures are followed.
A shipper’s declaration of dangerous goods is not required unless the dry ice is used as a refrigerant for other dangerous goods. Otherwise only an air waybill is required with the following information: Dry Ice or Carbon dioxide, solid, 9, UN 1845, number of packages and the net quantity of dry ice in each package.
The net weight of the dry ice in the package must be marked on the outside of the package in addition to the other required marks and labels (e.g., Dry Ice, UN 1845, Class 9 Miscellaneous label).
Dry ice is not regulated by the DOT as a hazardous material for ground (truck) shipments.
