Product classification
HS code for Mechanical clocks: 9105.99
Clocks, (excluding those with watch movements and instrument panel clocks), other than alarm or wall clocks, other than electrically operated.
Classification of mechanical clocks under HS 9105.99
Mechanical clocks that are neither alarm clocks nor wall clocks fall under HS code 9105.99. This is a residual category within heading 9105 for other clocks that are not electrically operated. The classification depends on the physical configuration and the intended placement of the clock. For instance, if a clock is designed to stand on a mantel, desk, or floor (such as a grandfather clock) and lacks an alarm function, it fits here. The not electrically operated requirement means the movement must be purely mechanical, usually involving a series of gears driven by a winding mechanism or weights. This code is often used for high-end horological pieces or traditional timepieces that eschew modern electronic components. Under the Harmonized System, the material of the case (e.g., wood, metal, or plastic) does not change the primary classification of the clock under 9105, although it may affect duty rates in certain jurisdictions. The key factor is the absence of any electrical power source for the timekeeping mechanism.

Codes often confused with 9105.99
Common mistake. This code is frequently confused with 9105.29, which is specifically for mechanical wall clocks. The distinction is based on the design for mounting; if the clock is intended to be hung on a wall, it must be classified under 9105.29. Another common error is using 9105.91, which is for other clocks that are electrically operated. Even if a clock has a mechanical appearance, if it uses a battery to move the hands, it belongs in 9105.91. Additionally, clocks with watch movements must be classified under heading 9103 rather than 9105.
Top exporters and importers of HS 910599 (the code used for mechanical clocks), 2025
In 2025, the largest exporter of HS 910599 (the code used for mechanical clocks) in UN Comtrade data was Switzerland, with 39% of world exports; the largest importer in UN Comtrade data was Switzerland, 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).
