Examples
Miscellaneous
dangerous goods
Class 9
RMD
Any substance which presents a danger during air transportation that is not covered by other classes. These include Aviation regulated solids or liquids, where materials may have an irritating, noxious or other properties which could cause extreme annoyance or discomfort to crew members preventing them from performing their duties.
