Product classification
HS code for Mechanical alarm clocks: 9105.19
Clocks, (excluding those with watch movements and instrument panel clocks), alarm clocks, other than electrically operated.
Classification of mechanical alarm clocks under HS 9105.19
Mechanical alarm clocks are classified under HS code 9105.19, which falls within Chapter 91 of the Harmonized System, covering clocks, watches, and their parts. This specific classification is determined by the General Rules of Interpretation (GRI), particularly GRI 1 and 6. Heading 9105 encompasses clocks that do not utilize watch movements (which are classified under 9103) and are not instrument panel clocks (9104). The subheading 9105.19 is reserved for alarm clocks that are not electrically operated. To qualify for this code, the device must feature an integrated alarm mechanism designed to sound at a pre-set time and must rely entirely on mechanical energy, typically stored in a mainspring that is manually wound. If the device uses a battery, a solar cell, or a mains power connection to drive the timekeeping or alarm function, it is excluded from this specific code. Customs authorities verify the classification by checking for the absence of electronic components, quartz crystals, or electrical wiring in the movement. The mechanical nature is defined by the use of an escapement and a balance wheel or pendulum to regulate time without electrical assistance.

Codes often confused with 9105.19
Common mistake. The most frequent misclassification occurs with HS code 9105.11, which is designated for electrically operated alarm clocks. Importers often confuse these because the external appearance may be identical; however, the internal power source is the deciding factor. Another common error involves HS code 9103.10, which covers alarm clocks with watch movements. According to Chapter 91 Note 3, a watch movement is defined by its dimensions (thickness not exceeding 12mm and width/diameter not exceeding 50mm). If a mechanical alarm clock uses a movement that meets these small dimensions, it must be moved to 9103.10.
Top exporters and importers of HS 910519 (the code used for mechanical alarm clocks), 2025
In 2025, the largest exporter of HS 910519 (the code used for mechanical alarm clocks) in UN Comtrade data was China, with 21% of world exports; the largest importer in UN Comtrade data was the United Kingdom, with 19% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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 mechanical alarm clocks
What is the HS code for Mechanical alarm clocks?
The HS code for Mechanical alarm clocks is 910519 (Clocks; (excluding those with watch movements and instrument panel clocks), alarm clocks, other than electrically operated). The primary HS code for mechanical alarm clocks (not electrically operated) is 9105.19.
How do I classify Mechanical alarm clocks for customs?
Mechanical alarm clocks is classified under HS code 910519 — Clocks; (excluding those with watch movements and instrument panel clocks), alarm clocks, other than electrically operated. This is a 6-digit subheading level code.
How do I distinguish between 9105.11 and 9105.19?
The distinction is based on the power source. 9105.11 is for clocks powered by electricity (batteries or AC), while 9105.19 is for clocks powered by mechanical means like a wound spring.
Which countries are the top exporters of mechanical alarm clocks (HS 910519)?
In 2025, the top exporters of HS 910519 (the code used for mechanical alarm clocks) in UN Comtrade data were China ($1.6M, 21% of world exports), Denmark ($1.4M) and Saudi Arabia ($688K). World exports came to about $7.8M, 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 mechanical alarm clocks (HS 910519)?
