Product classification
HS code for Smoke detector: 8531.10
Signalling apparatus, electric, sound or visual, burglar or fire alarms and similar, other than those of heading no. 8512 or 8530.
Classification of smoke detector under HS 8531.10
The classification of smoke detectors under HS code 8531.10 is determined by their primary function as electrical signaling apparatus designed for fire protection. According to the General Rules for the Interpretation (GRI) of the Harmonized System, products are classified based on the terms of the headings and any relative section or chapter notes. Heading 8531 specifically covers electric sound or visual signaling apparatus. Within this heading, subheading 8531.10 is dedicated to burglar or fire alarms and similar apparatus. Smoke detectors function by sensing aerosol particles or heat and then activating an integrated or remote alarm. This specific utility as a life-safety device for fire detection ensures its placement in this category. The classification remains consistent whether the device utilizes ionization technology, which uses a small amount of radioactive material to detect smoke, or photoelectric technology, which uses light sensors. Furthermore, the inclusion of smart features or wireless connectivity does not typically change this classification, as the essential character of the device remains a fire alarm signaling apparatus.

Codes often confused with 8531.10
Common mistake. Smoke detectors are frequently confused with HS code 9027.10, which covers gas or smoke analysis apparatus. However, 9027.10 is intended for laboratory or industrial instruments that analyze the composition of smoke, whereas 8531.10 is for simple signaling and warning devices. Another common error is using 8531.80, which is a residual category for other signaling apparatus, but since fire alarms are specifically named in 8531.10, that code must take precedence.
Top exporters and importers of HS 853110 (the code used for smoke detector), 2025
In 2025, the largest exporter of HS 853110 (the code used for smoke detector) in UN Comtrade data was China, with 17% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 853110, not only smoke detector.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about smoke detector
What is the HS code for Smoke detector?
The HS code for Smoke detector is 853110 (Signalling apparatus; electric, sound or visual, burglar or fire alarms and similar, other than those of heading no. 8512 or 8530). The standard HS code for a smoke detector is 8531.10, which covers electric fire alarms and similar signaling apparatus.
How do I classify Smoke detector for customs?
Smoke detector is classified under HS code 853110 — Signalling apparatus; electric, sound or visual, burglar or fire alarms and similar, other than those of heading no. 8512 or 8530. This is a 6-digit subheading level code.
Are smart smoke detectors classified differently?
No, smart smoke detectors with Wi-Fi or Bluetooth capabilities are still classified under 8531.10 because their primary function is still fire signaling.
Which countries are the top exporters of smoke detector (HS 853110)?
In 2025, the top exporters of HS 853110 (the code used for smoke detector) in UN Comtrade data were China ($1.1B, 17% of world exports), Mexico ($558M) and Germany ($509M). World exports came to about $6.3B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of smoke detector (HS 853110)?
