HS Code 9107.00 – Time switches; with clock, watch movement or synchronous motor
HS code 9107.00 is the 6-digit subheading for time switches, with clock, watch movement or synchronous motor. It is used for digital programmable time switches, analog mechanical timers, astronomical time switches, DIN rail timers and smart home timers.
What HS 9107.00 covers
This HS code covers time switches, which are devices designed to automatically switch an electrical circuit on or off at pre-set times, utilizing a clock, watch movement, or synchronous motor. These are fundamental components in automation, used across residential, commercial, and industrial sectors to control lighting, heating, ventilation, machinery, and security systems. Importers include electrical distributors, construction companies, smart home integrators, and manufacturers of appliances. Exporters are typically companies specializing in electrical controls, automation, and energy management solutions. Key trade considerations include programming flexibility (digital vs. analog), energy efficiency features, reliability, ease of installation, and compatibility with smart building or IoT ecosystems.

Codes often confused with 9107.00
Common mistake. Can be confused with 8536 (electrical apparatus for switching or protecting electrical circuits) if the primary function is seen as general switching rather than time-based control, or 8537 (boards, panels, consoles for electrical control) if part of a larger system.
Top exporters and importers of HS code 910700, 2025
In 2025, the largest exporter of HS code 910700 in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was the United States, with 24% 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).
