I understand carbonated drinks in allowed in cabin, but, is it allowed in air cargo transportation, when you ship in bulk?
Each operator is of course entitled to apply stricter regulations, but there's no restriction against carbonated drinks in the IATA-DGR (based on the ICAO TI, which sets out the framework for dangerous goods regulations).
The maximum amount of pure CO2 an operator may transport in approved packaging (iaw. IATA-DGR) is:
- In gaseous form (UN1013): 150 kg on cargo only aircraft, and 75 kg in passenger/cargo aircraft.
- In liquid form (UN2187): 500 kg on cargo only aircraft, and 50 kg in passenger/cargo aircraft.
- In solid form "dry ice" (UN1845): 200 kg for both cargo and passenger/cargo aircraft
No, Carbonated drinks are generally not dangerous, and are labelled in such a way to let anyone who is transporting them know the contents of the carbonated drink. Before they become dangerous though, other factors would have had to happen that would be considered even more dangerous; The airline would have had to have a sudden change of pressure, such a change would cause a loss of consciousness for all those travelling on board the airline, and doing so would release CO2 from the cans.
