9108 - Watch movements, complete and assembled:

Sub-classifications

Commodity Code
Description

Overview

HTS Code 9108 encompasses complete and assembled watch movements. These are the internal mechanisms of watches that comprise all the essential components for timekeeping, such as the mainspring, gear train, escapement, and balance wheel, ready for integration into a watch case. The classification is specific to the movement itself, not a complete timepiece with a casing and dial.

This category is distinct from other HTS sections that may involve components or finished goods. For instance, it does not cover individual parts of watch movements, which would fall under a different HTS code within Chapter 91 or potentially other chapters depending on the specific part. It also differs from finished watches (classified under 9101 or 9102), which are complete timekeeping devices ready for sale and wear.

Within HTS 9108, further subdivisions exist to differentiate movements based on their operational characteristics. Subheadings like 9108.20 specify movements with automatic winding mechanisms, which are powered by the wearer's motion. Other movements, not falling into the automatic winding category, are classified under the residual subheading 9108.90, "Other," encompassing manually wound or other types of powered movements that do not meet the criteria for automatic winding.
