Household smoke detectors using americium-241. Class 7 radioactive but classified as 'excepted package' under IATA — clears as routine personal effect. Single household ionisation-chamber smoke detectors typically clear personal-baggage and postal carriage as routine consumer electronics because the americium-241 source is below the IATA Excepted-Package activity limit (40 kBq for solid Am-241). Bulk commercial shipments of smoke detectors are still Class 7 Excepted Package and ship under UN 2911 with an Excepted-Package mark on the outer carton. Photoelectric detectors contain no radioactive source and are unrestricted.

Common mistakes with Smoke detector (with Am-241)

• 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.
• Lithium batteries in checked baggage (must be in carry-on) or above the watt-hour limit without airline approval.
• Missing required certificates (phytosanitary, veterinary, CITES, prescription, product compliance).

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