HS Code 9108.12 – Watch movements; complete and assembled, electrically operated, by means of solar cells, with opto-electronic display
HS code 9108.12 is the 6-digit subheading for watch movements, complete and assembled, electrically operated, by means of solar cells, with opto-electronic display. It is used for solar-powered digital watch movements, eco-Drive movements, tough Solar movements, LCD watch movements (solar) and LED watch movements (solar).
What HS 9108.12 covers
This HS code covers complete and assembled watch movements that are electrically operated by means of solar cells and feature an opto-electronic display, typically a digital LCD or LED screen. These movements represent a sustainable and technologically advanced segment of watchmaking, eliminating the need for traditional battery replacement by converting light into electrical energy. Importers are watch brands focused on eco-friendly, high-tech, or outdoor-oriented digital watches. Exporters are specialized manufacturers with expertise in both microelectronics and solar power integration. Key features for trade include energy conversion efficiency, advanced display capabilities (e.g., multi-function displays), and often additional functionalities like atomic time synchronization or power reserve indicators.

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).
