Aerosols — dangerous goods classification
Every aerosol is UN1950. The division follows the propellant, not the payload: a butane or propane propellant makes the article Division 2.1 even if the contents are water-based.
The mistake this category generates
Aerosols have NO packing group. Putting one on a shipping paper is an immediate sign the classification was guessed.

Shipper notes
UN1950 Aerosols, flammable
- Aerosols have no packing group. A flammable propellant — butane, propane, isobutane, DME — makes the article Division 2.1 whatever the payload is.
- Aerosols with a capacity of 1 L or less are the classic limited-quantity case under 49 CFR 173.306, which is what makes ground shipment practical.
UN1950 Aerosols, non-flammable
- Compressed-air dusters and nitrogen-propelled sprays fall here. Many 'canned air' products actually use a flammable HFC/hydrocarbon blend — read the SDS before choosing between the 2.1 and 2.2 entries.
