HS Code for Quartz clock movements

Quartz clock movements are classified under HS code 9109.10. This classification is part of Chapter 91, dedicated to horological instruments. Heading 9109 covers clock movements that are complete and assembled. This distinguishes them from watch movements (heading 9108) and from individual parts or unassembled sets (heading 9110). The subheading 9109.10 specifically targets movements that are electrically operated, which includes the vast majority of modern quartz movements used in wall clocks, desk clocks, and various industrial timing devices. The classification relies on the movement being a finished, functional unit ready for installation into a clock case. It must meet the technical definition of a "clock movement" rather than a "watch movement," which is generally determined by the dimensions of the movement. Specifically, if the movement is thicker than 12 mm or wider than 50 mm, it is classified as a clock movement. These units typically consist of a quartz crystal oscillator, an integrated circuit, and either a stepper motor for analog hands or a display driver for digital outputs.

Products Included

• Radio-controlled quartz clock movements

Common Misclassification

The most common misclassification is 9108.11, which is for quartz watch movements. The distinction depends on the size of the movement. Another error is using 9114.90 for clock parts; however, 9114 is for individual components, whereas 9109.10 is for complete, assembled movements. If the movement is unassembled or partly assembled, it should be classified under 9110.11.

FAQ

What is the HS code for Quartz clock movements?

The HS code for complete and assembled electrically operated quartz clock movements is 9109.10.

What defines a movement as a clock movement instead of a watch movement?

A movement is classified as a clock movement if it exceeds 12 mm in thickness or 50 mm in width/diameter; otherwise, it is usually a watch movement under heading 9108.
