The net weight of the dry ice must be marked on the outside of the package along with the words "Carbon dioxide, solid", UN 1845 and a miscellaneous dangerous goods class diamond (class 9).
The packaging instruction from the current IATA Dangerous Goods Regulations should be consulted.

A shipper's declaration is only required when the carbon dioxide, solid is used as a refrigerant for dangerous goods that require a shipper's declaration.
When a shipper's declaration is not required, the following information, required for the carbon dioxide, solid must be contained in the "Nature and Quantity of Goods" box on the airway bill: • Proper shipping name: Carbon dioxide, solid • Class 9 • UN 1845 • The number of packages • The net quantity of carbon dioxide, solid in each package.
