HS Code 9110.90 – Clocks; movements, whether or not complete, incomplete, assembled or unassembled

HS code 9110.90 is the 6-digit subheading for clocks, movements, whether or not complete, incomplete, assembled or unassembled. It is used for quartz clock movements, mechanical pendulum clock movements, chime clock mechanisms, atomic clock movements and cuckoo clock movements.

What HS 9110.90 covers

This broad HS code covers all forms of clock movements, from fully assembled and ready-to-install units to individual components or partially assembled sets, regardless of their completion stage. Unlike watch movements, which are highly specialized, clock movements cater to a wider range of applications, including wall clocks, desk clocks, grandfather clocks, and even industrial timers. Importers are typically clock manufacturers, furniture makers incorporating clocks, or repair shops seeking replacement parts. Exporters are often specialized movement manufacturers, particularly from Asia (for quartz) and Europe (for mechanical). Key considerations include the type of movement (quartz, mechanical, atomic), power source, size, and specific functions (e.g., chime mechanisms, pendulum drives). The trade reflects global demand for timekeeping devices beyond personal wristwear, supporting both decorative and functional clock production worldwide.

Codes often confused with 9110.90

Common mistake. This code is distinct from watch movements (9110.1x series) due to the specific mention of "clocks," but could be confused with parts of clocks (9114.90) if the item is not clearly a "movement."

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
