Product classification
HS code for Digital solar watch movements: 9108.12
Watch movements, complete and assembled, electrically operated, by means of solar cells, with opto-electronic display.
Classification of digital solar watch movements under HS 9108.12
Digital solar watch movements are classified under HS code 9108.12. This classification is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically focusing on the technical characteristics of the movement. Heading 9108 covers watch movements that are complete and assembled. The subheading 9108.12 is specifically reserved for movements that are electrically operated, utilizing solar cells to convert light into electrical energy, and featuring an opto-electronic display, such as a Liquid Crystal Display (LCD) or Light Emitting Diode (LED). Unlike mechanical movements or standard battery-operated quartz movements with analog hands, these movements rely on a combination of photovoltaic technology and electronic circuitry to maintain time and drive the digital interface. The classification remains consistent regardless of whether the solar cell is integrated into the movement or connected as a primary power source, provided the display remains opto-electronic.

Codes often confused with 9108.12
Common mistake. A frequent point of confusion occurs with HS code 9108.11, which covers movements with a mechanical display or those that incorporate a device to which a mechanical display can be incorporated. If a solar movement uses analog hands, it belongs in 9108.11, not 9108.12. Additionally, 9108.19 is often used incorrectly; this is a residual category for other electrically operated movements that do not meet the specific solar or opto-electronic criteria of the preceding subheadings. Importers must also distinguish these from 9110, which covers incomplete or partially assembled movements.
Top exporters and importers of HS 910812 (the code used for digital solar watch movements), 2025
In 2025, the largest exporter of HS 910812 (the code used for digital 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 digital solar watch movements
What is the HS code for Digital solar watch movements?
The HS code for Digital solar watch movements is 910812 (Watch movements; complete and assembled, electrically operated, by means of solar cells, with opto-electronic display). The correct HS code is 9108.12, which applies to complete and assembled watch movements that are electrically operated by solar cells and feature an opto-electronic display.
How do I classify Digital solar watch movements for customs?
Digital 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.
Does this code include the watch case?
No, HS code 9108.12 only covers the movement itself. If the movement is already installed in a case, the product would be classified as a complete watch under heading 9101 or 9102.
Which countries are the top exporters of digital solar watch movements (HS 910812)?
In 2025, the top exporters of HS 910812 (the code used for digital 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 digital solar watch movements (HS 910812)?
