Aerosol cans using non-flammable propellants — typically HFC-134a, HFC-152a, carbon dioxide (CO2), or compressed air (N2). Used in: compressed-air dusters (electronics cleaning), pressurised dust-off cans, photographic-blower kits, asthma inhalers, certain pepper-spray formulations (where US-spec OC sprays use HFC-134a propellant). Classified IATA Dangerous Goods Class 2.2 non-flammable gas — significantly less restricted than Class 2.1 flammable aerosols.

Common mistakes with Aerosol cans (non-flammable propellant)

• Assuming the rules at the origin apply at the destination — they don't. The destination customs authority is the binding rule.
• Travelling and posting are treated differently: an item you can carry may be prohibited by post (and vice versa).
• Personal vs commercial intent: above a quantity threshold, customs may treat your shipment as commercial regardless of intent.
• Undervaluing on the customs declaration to avoid duty — treated as fraud in most jurisdictions.
• Vague item descriptions on CN22/CN23 — biggest single cause of postal customs holds.
• Missing required certificates (phytosanitary, veterinary, CITES, prescription, product compliance).

Always verify against the destination's customs authority before acting. Not legal advice.
