Product classification
HS code for Programmable timers: 9107.00
Time switches, with clock, watch movement or synchronous motor.
Classification of programmable timers under HS 9107.00
Programmable timers are classified under HS code 9107.00 because they function as time switches equipped with a clock or watch movement or a synchronous motor. This classification is determined by the device's primary function: making or breaking an electrical connection at predetermined times. Unlike simple manual switches, these devices incorporate a timing mechanism that operates independently once set. The General Rules for Interpretation (GRI) dictate that such apparatus, which includes a clock-type movement to trigger an electrical circuit, falls specifically within Chapter 91, which covers horological instruments and their parts. The inclusion of a synchronous motor or a clock movement is the defining technical characteristic that separates these from general electrical switches found in Chapter 85.

Codes often confused with 9107.00
Common mistake. Programmable timers are frequently misclassified under HS code 8536.50, which covers general electrical switches. However, if the switch is controlled by a clock-type movement or synchronous motor, 9107.00 takes precedence. Another common error is using HS code 9106.90, which is intended for time of day recording apparatus; while related, 9106 is for recording time, whereas 9107 is for switching circuits based on time.
Top exporters and importers of HS 910700 (the code used for programmable timers), 2025
In 2025, the largest exporter of HS 910700 (the code used for programmable timers) 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 programmable timers
What is the HS code for Programmable timers?
The HS code for Programmable timers is 910700 (Time switches; with clock, watch movement or synchronous motor). The primary HS code for programmable timers with a clock movement or synchronous motor is 9107.00.
How do I classify Programmable timers for customs?
Programmable timers is classified under HS code 910700 — Time switches; with clock, watch movement or synchronous motor. This is a 6-digit subheading level code.
Does this code include smart home Wi-Fi switches?
If the device relies purely on a microprocessor and software without a traditional clock movement or synchronous motor, it may be classified under 8537; however, most dedicated time-of-day switches remain in 9107.00.
Which countries are the top exporters of programmable timers (HS 910700)?
In 2025, the top exporters of HS 910700 (the code used for programmable timers) 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 programmable timers (HS 910700)?
In 2025, the top importers of HS 910700 (the code used for programmable timers) 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 Programmable timers the same in all countries?
The base HS code 910700 for Programmable timers 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 programmable timers in Brazil?
Brazil splits HS 910700 into 2 NCM codes, so the right one for programmable timers depends on the product's details: 9107.00.10 (Time switches), 9107.00.90 (Other timers with clock or synchronous motor).
