Are carbonated drinks considered dangerous goods for air freight? 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
