Product classification
HS code for Solar watch movements: 9108.12
Watch movements, complete and assembled, electrically operated, by means of solar cells, with opto-electronic display.
Classification of solar watch movements under HS 9108.12
HS code 9108.12 is designated for complete and assembled watch movements that are electrically operated by means of solar cells and feature an opto-electronic display. This classification is highly specific, focusing on the internal mechanism of the watch rather than the finished timepiece. The inclusion of solar cells as the primary power source and the requirement for an opto-electronic display, such as an LCD or LED, are the primary factors for this classification. These movements are sophisticated components that integrate photovoltaic technology with micro-electronics to maintain timekeeping without the need for traditional battery replacements. The classification process involves verifying that the movement is fully functional and assembled upon import. Because these movements rely on photovoltaic energy to charge an internal capacitor or secondary battery, they are distinguished from standard battery-operated quartz movements that lack solar charging capabilities.

Codes often confused with 9108.12
Common mistake. These movements are often confused with HS code 9108.11, which is for movements with mechanical displays (hands) only, or 9108.19, which is a catch-all for other electrically operated movements. The presence of an opto-electronic display is the key differentiator that mandates the use of 9108.12. If the watch has hands but is solar-powered, it may fall under 9108.11 instead.
Top exporters and importers of HS 910812 (the code used for solar watch movements), 2025
In 2025, the largest exporter of HS 910812 (the code used for solar watch movements) in UN Comtrade data was China, with 47% of world exports; the largest importer in UN Comtrade data was Thailand, with 58% 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 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).

Questions about solar watch movements
What is the HS code for Solar watch movements?
The HS code for Solar watch movements is 910812 (Watch movements; complete and assembled, electrically operated, by means of solar cells, with opto-electronic display). The HS code for solar-powered watch movements with opto-electronic displays is 9108.12.
How do I classify Solar watch movements for customs?
Solar watch movements is classified under HS code 910812 — Watch movements; complete and assembled, electrically operated, by means of solar cells, with opto-electronic display. This is a 6-digit subheading level code.
What if the solar watch movement has traditional hands?
If the movement uses hands to show time (analog) rather than a digital display, it is typically classified under 9108.11, even if it is solar-powered.
Which countries are the top exporters of solar watch movements (HS 910812)?
In 2025, the top exporters of HS 910812 (the code used for solar watch movements) in UN Comtrade data were China ($3.5M, 47% of world exports), Hong Kong ($1.4M) and Singapore ($1.4M). World exports came to about $7.4M, 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 solar watch movements (HS 910812)?
In 2025, the top importers of HS 910812 (the code used for solar watch movements) in UN Comtrade data were Thailand ($11M, 58% of world imports), China ($1.7M) and the United Arab Emirates (about $1.3M). World imports came to about $18M, 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.
