We apologize for the delay in responding and any inconvenience this may\nhave caused. You note that the ICAO TI dangerous goods list shows seventeen UN1950\n\"Aerosols\" entries with varying primary and subsidiary hazards, while the HMR hazardous\nmaterials table (HMT) only lists five \"Aerosols\" entries. You further note that no person may\noffer for transportation or transport a hazardous material that is a forbidden material or package\nthat meets one of the provisions in § 171.22(e). In your request you provide an example of a\nproduct that is described under the ICAO TI as \"Aerosols, flammable 2.1 (6.1) PG III\", and\nnoting that this is not an entry in the HMT, ask how an air carrier can ensure the material is not\nforbidden for transport as required by § 171.22(e) if the material is not listed in the HMT?\nSection 173.115(1)(6) prohibits the transportation of substances of Division 6.1, PG I or II, and\nsubstances of Class 8, PG I in an aerosol container. This prohibition is in line with the Dangerous\nGoods List (DGL) entries for similar aerosols in the ICAO TI. Section 173.115(I)(5) requires that\nwhen the aerosol contents are classified as Division 6.1, PG III or Class 8, PG II or III, the aerosol\nmust be assigned a subsidiary hazard of Division 6.1 or Class 8, as appropriate. The transport\nconditions and quantity authorizations for the HMT entry \"UN 1950 Aerosols, flammable\" align\nwith the DGL entry \"UN 1950 Aerosols, flammable 2.1 (6.1) PG III.\" In this specific case, in\norder to verify that the shipment is not forbidden one should consult the appropriate HMT entry\nfor the primary hazard (UN 1950 Aerosols, Flammable).\nI trust this information is helpful. If you have further questions, please do not hesitate to contact\nthis office.\nSincerely,\nDuane A.
