HS Code for Self-winding watch movements

Self-winding watch movements, also known as automatic movements, are classified under Chapter 91 of the Harmonized System, which covers clocks and watches and parts thereof. Specifically, they fall under Heading 9108, which is reserved for watch movements that are complete and assembled. Subheading 9108.20 is the specific designation for movements with automatic winding. The classification is determined by the mechanical nature of the movement and the presence of a self-winding mechanism, typically involving an oscillating weight or rotor that winds the mainspring through the motion of the wearer's wrist. According to the Chapter Notes for Chapter 91, "watch movements" are devices regulated by a balance wheel and hairspring, quartz crystal, or any other system capable of determining intervals of time, with a display or a system to which a mechanical display can be incorporated. They must also be of a thickness not exceeding 12 mm and a width, length, or diameter not exceeding 50 mm. Self-winding movements are distinguished from manual-wind movements by their ability to store energy without manual intervention.

Products Included

Common Misclassification

These movements are often misclassified under 9108.11, which is for battery-powered or electrically operated movements with mechanical displays. They may also be confused with 9108.90, which covers "other" watch movements, including manual-wind versions. Additionally, if the movement is not complete or not assembled, it must be classified under Heading 9110. It is also important to distinguish them from clock movements (Heading 9109) based on the size and thickness dimensions specified in the chapter notes.

FAQ

What is the HS code for self-winding watch movements?

The HS code for complete and assembled self-winding watch movements is 9108.20.

What if the automatic movement is imported inside a watch case?

If the movement is already inside a case, the entire item is classified as a watch under Heading 9101 or 9102, not as a movement.
