Product classification
HS code for Time switches: 9107.00
Time switches, with clock, watch movement or synchronous motor.
Classification of time switches under HS 9107.00
HS code 9107.00 is the specific classification for time switches that incorporate a clock or watch movement or a synchronous motor. These devices are designed to automatically open or close electrical circuits at one or more predetermined times. The classification is governed by the requirement that the switching mechanism must be integrated with a chronometric movement. This movement acts as the control unit, triggering the mechanical or electronic relay at the set interval. Time switches are used extensively in both residential and industrial applications to automate processes such as lighting, heating, and machinery operation. The classification covers a wide range of complexities, from simple 24-hour plug-in timers to sophisticated multi-channel programmable switches used in building management systems. The key factor for classification under 9107.00 is the presence of the timing movement; without it, the device might be classified as general electrical apparatus. This heading is a single-level code in the international nomenclature, simplifying the categorization of these automated timing controls.

Codes often confused with 9107.00
Common mistake. Time switches are often misclassified under heading 85.36, which covers general electrical switches and relays. The primary difference is that 85.36 switches do not contain a clock or watch movement. If the timing function is provided by a simple RC circuit or an external signal rather than an internal chronometric movement, it belongs in Chapter 85. Additionally, time switches are sometimes confused with time recording apparatus in 91.06, which record time rather than switching circuits.
Top exporters and importers of HS 910700 (the code used for time switches), 2025
In 2025, the largest exporter of HS 910700 (the code used for time switches) 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).

Questions about time switches
What is the HS code for Time switches?
The HS code for Time switches is 910700 (Time switches; with clock, watch movement or synchronous motor). The HS code for time switches with a clock, watch movement, or synchronous motor is 9107.00.
How do I classify Time switches for customs?
Time switches is classified under HS code 910700 — Time switches; with clock, watch movement or synchronous motor. This is a 6-digit subheading level code.
Do digital timers without mechanical parts fall under 9107.00?
Yes, digital timers are classified under 9107.00 provided they function as time switches and contain an electronic clock movement or synchronous motor to control the circuit.
Which countries are the top exporters of time switches (HS 910700)?
In 2025, the top exporters of HS 910700 (the code used for time switches) in UN Comtrade data were China ($127M, 26% of world exports), Mexico ($91M) and France ($46M). World exports came to about $491M, 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 time switches (HS 910700)?
In 2025, the top importers of HS 910700 (the code used for time switches) in UN Comtrade data were the United States ($138M, 24% of world imports), Germany ($53M) and France ($37M). World imports came to about $564M, 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.
Is the HS code for Time switches the same in all countries?
The base HS code 910700 for Time switches is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for time switches in Brazil?
Brazil splits HS 910700 into 2 NCM codes, so the right one for time switches depends on the product's details: 9107.00.10 (Time switches), 9107.00.90 (Other timers with clock or synchronous motor).
