Product classification
HS code for Manual clock movements: 9109.90
Clock movements, complete and assembled, other than electrically operated.
Classification of manual clock movements under HS 9109.90
Manual clock movements are classified under HS code 9109.90, which pertains to clock movements that are complete and assembled but are not electrically operated. Chapter 91 of the Harmonized System governs clocks, watches, and their parts. Heading 9109 is distinct from 9108, which covers watch movements, based on the size and intended use of the mechanism. Generally, clock movements are larger than watch movements or are intended for stationary timepieces. The subheading 9109.90 specifically captures mechanical movements that rely on manual winding, weights, or springs to function, as opposed to those powered by batteries or AC current, which fall under 9109.10. This classification is essential for identifying traditional horological components that do not incorporate electronic circuits or quartz crystals for timekeeping. The movement must be complete and assembled to qualify; individual parts or unassembled sets fall under different codes within the same chapter.

Codes often confused with 9109.90
Common mistake. The most frequent misclassification occurs between HS code 9109.90 and 9108.90. The latter is reserved for watch movements. According to the Chapter 91 notes, movements are classified as watch movements if they are regulated by a balance-wheel and hairspring and are less than 12mm in thickness or 50mm in width/diameter. If they exceed these dimensions, they are clock movements. Another error is using 9109.10, which is strictly for electrically operated movements (quartz or synchronous). Finally, incomplete or unassembled movements should be classified under 9110 rather than 9109.
Top exporters and importers of HS 910990 (the code used for manual clock movements), 2025
In 2025, the largest exporter of HS 910990 (the code used for manual clock movements) in UN Comtrade data was Germany, with 36% of world exports; the largest importer in UN Comtrade data was the United States, with 31% 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 manual clock movements
What is the HS code for Manual clock movements?
The HS code for Manual clock movements is 910990 (Clock movements; complete and assembled, other than electrically operated). Manual, non-electric clock movements that are complete and assembled are classified under HS code 9109.90.
How do I classify Manual clock movements for customs?
Manual clock movements is classified under HS code 910990 — Clock movements; complete and assembled, other than electrically operated. This is a 6-digit subheading level code.
How do I distinguish between a watch and clock movement for customs?
Classification depends on size; movements thicker than 12mm or wider than 50mm are generally classified as clock movements under 9109.
Which countries are the top exporters of manual clock movements (HS 910990)?
In 2025, the top exporters of HS 910990 (the code used for manual clock movements) in UN Comtrade data were Germany ($3.6M, 36% of world exports), Switzerland ($1.8M) and Italy ($1.6M). World exports came to about $10M, 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 manual clock movements (HS 910990)?
