The shipping of ice cream can be classified as a dangerous good, or hazmat for transport if it’s packed in dry ice. As a result of the dry ice, the shipment becomes a hazardous consignment as dry ice evaporates over time releasing carbon dioxide gas. Normal air is 78% nitrogen, 21% oxygen and only 0.035% carbon dioxide. If the concentration of carbon dioxide in the air rises above 5%, carbon dioxide can become toxic.
By using the correct amount of dry ice it is possible to meet the stringent requirements of maintaining a specific maximum temperature within a package during its transport period. The precise amount required will depend on many factors, including; the insulating properties of the box, the mass of goods to be maintained at temperature, the starting temperature of the goods, the arrangement of the goods and dry ice within the packaging, the climatic conditions during the transport period, the length of the transport period, and the allowance made for possible delivery delays.
Most importantly, consult with your shipping agent to confirm that your dry ice shipment is compliant and safe.
