Product classification
HS code for Electric clock movements: 9109.10
Clock movements, complete and assembled, electrically operated.
Classification of electric clock movements under HS 9109.10
Electric clock movements are classified under HS code 9109.10 because they fall within Chapter 91, which covers clocks, watches, and their parts. Specifically, heading 9109 is designated for clock movements that are complete and assembled but are not intended for watches (which are covered under 9108). The subheading 9109.10 is reserved for those movements that are electrically operated. This includes movements powered by a battery, an accumulator, or connected to a main power source. The classification is determined by the primary function of the component—providing the mechanical or electronic drive for a clock—and its method of operation. These movements typically consist of a motor or an electronic circuit that regulates the timekeeping and drives the hands or digital display. Because they are \"complete and assembled,\" they must be ready for installation into a clock case without further assembly of the internal timing mechanism. According to General Interpretative Rule (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes.

Codes often confused with 9109.10
Common mistake. Electric clock movements are frequently confused with watch movements under heading 9108. The distinction lies in the size and intended use; 9108 is for movements that are small enough for watches (generally less than 12mm in thickness or 33.8mm in width). Additionally, they may be misclassified under 9110 if they are incomplete or partially assembled. Another common error is using 8501 for electric motors; however, if the motor is integrated into a clock movement, Chapter 91 takes precedence over Chapter 85.
Top exporters and importers of HS 910910 (the code used for electric clock movements), 2025
In 2025, the largest exporter of HS 910910 (the code used for electric clock movements) in UN Comtrade data was China, with 65% of world exports; the largest importer in UN Comtrade data was Hong Kong, with 10% 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).
