HS Code for Programmable timers

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.

Products Included

• Digital programmable time switches
• Mechanical plug-in timers for household appliances
• Industrial DIN rail mounted timers
• Astronomical time switches
• Electronic 7-day programmable timers

Common Misclassification

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.

FAQ

What is the HS code for programmable timers?

The primary HS code for programmable timers with a clock movement or synchronous motor is 9107.00.

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.
