Subheading 4 of 4 in heading 9110
Assembled watch movements that are missing one or more functional components occupy this heading — a classification that arises frequently in multi-stage manufacturing supply chains where movements are partially built before export. Japan and Switzerland are the leading sources, with China, Italy, and India also supplying the US market. Because these movements are assembled but functionally incomplete, importers must be able to document which components are absent to defend classification against CBP scrutiny, particularly when the goods could otherwise be argued to qualify as complete movements or as parts.

Technical documentation from the manufacturer identifying the specific missing component(s) — such as a balance wheel, escapement, or dial train element — is the most defensible approach. CBP may compare the movement against the full component list for that caliber to confirm the incomplete designation under 9110120000.
Potentially, yes. If the missing components are so fundamental that the assembly no longer functions as a recognizable movement, CBP could argue classification as parts under Chapter 91. The key is whether the assembly retains the essential character of a movement; importers in doubt should seek a binding ruling before shipment.
