UN 1845 – Carbon dioxide, solid (Dry ice)

Packaging tests are not considered necessary.

When dry ice is used as a refrigerant for other than dangerous goods loaded in a unit load device, the quantity limits per package shown in columns 11 and 13 in Table 3-1 for dry ice do not apply. In such case, the unit load device must be identified to the operator and must allow the venting of the carbon dioxide gas to prevent a dangerous build-up of pressure.
