Der stabilisierte Stoff ist namentlich der UN-Nr. 1921 zugeordnet.
Für den unstabilisierten Stoff siehe 2.3.5 der UN-Modellvorschriften:

"Chemically unstable substances of Class 3 shall not be accepted 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 386 of Chapter 3.3. To this end particular care shall be taken to ensure that receptacles and tanks do not contain any substances liable to promote these reactions."
