IATA Class 9 - Dry Ice Packing Instructions

Dry ice must be packed in accordance with Packing Instruction 954. Packages must be designed, constructed, and prepared to permit the release of carbon dioxide gas during transit. Dry ice must never be placed in an airtight, unvented container. The pressure buildup from the carbon dioxide gas could cause the package to explode.

The packaging used for dry ice must be able to withstand the normal rigors of air transport, including vibration, rough handling, and changes in temperature, humidity, and altitude. The packaging must also be able to withstand extremely low temperatures. Some plastics can become brittle or permeable at low temperatures and should not be used with dry ice.

The shipper must make prior arrangements with the operator for each shipment of dry ice. This is to ensure that the proper ventilation safety procedures are followed.

The net weight of dry ice must be marked on the outside of the package. If packages are placed in an overpack, then the overpack must be marked with the total net quantity of dry ice in the overpack.

200 kg of dry ice per package is permitted on passenger and cargo aircrafts. However, if dry ice is being used as a refrigerant for non-dangerous goods loaded in a unit load device, then the quantity limits do not apply. The only requirements are that the unit load device be identified to the operator and must allow for proper venting.

Packaging tests are not required for packages of dry ice, along with other non-dangerous goods.
