Der stabilisierte Stoff ist namentlich der UN-Nr. 1085 zugeordnet.
Für den unstabilisierten Stoff siehe 2;2.6 der ICAO TI:

"Chemically unstable gases of Class 2 are forbidden for transport unless the necessary precautions have been taken to prevent the possibility of a dangerous decomposition or polymerization under normal conditions of transport. For the precautions necessary to prevent polymerization, see Special Provision A209. To this end, particular care must be taken to ensure that receptacles do not contain any substances liable to promote these reactions."
