HAZMAT Class 9 Miscellaneous

The miscellaneous hazardous materials category encompasses all hazardous materials that do not fit one of the definitions listed in Class 1 through Class 8.

Divisions
Class 9A: Lithium batteries

The miscellaneous hazardous material is a material that presents a hazard during transportation but which does not meet the definition of any other hazard class. This class includes:

  1. Any material which has an anesthetic, noxious or other similar property which could cause extreme annoyance or discomfort to a flight crew member so as to prevent the correct performance of assigned duties; or
  2. Any material that meets the definition in 49 CFR 171.8 for an elevated temperature material, a hazardous substance, a hazardous waste, or a marine pollutant.

A new sub-class, class 9A, has been in effect since January 1, 2017. This is limited to the labeling of the transport of lithium batteries.
