HS Code for Timer switches

Timer switches are classified under HS code 9107.00. This heading is unique because it sits at the intersection of electrical equipment and horology. It covers time switches with a clock or watch movement or with a synchronous motor. These devices are designed to automatically open or close electrical circuits at one or more predetermined times. The classification is determined by the integration of a time-measuring mechanism (the movement) with an electrical switching apparatus. This includes mechanical timers where a spring-driven clockwork triggers a switch, as well as electronic timers that use a synchronous motor or a quartz crystal movement to control the timing of the circuit. Because the timing mechanism is the defining feature of the switch's operation, the Harmonized System places these items in Chapter 91 (Clocks and watches) rather than Chapter 85 (Electrical machinery). This follows GRI 1, as the heading 9107.00 specifically describes this combined functionality.

Products Included

• Mechanical time switches
• Electronic timer switches with clock movements
• Industrial time-controlled relays
• Synchronous motor-driven switches
• Programmable time switches for lighting

Common Misclassification

The most frequent misclassification is under HS code 8536, which covers general electrical switches and relays. While a timer switch does perform switching, the presence of a clock movement or synchronous motor mandates classification in 9107.00. Another error is confusing them with 9106 (time recorders), which record time rather than switching a circuit based on time.

FAQ

What is the HS code for Timer switches?

The HS code for timer switches with a clock movement or synchronous motor is 9107.00.

Are simple delay relays classified here?

No, simple thermal or RC (resistor-capacitor) delay relays that do not contain a clock movement or synchronous motor are typically classified under HS code 8536.
