Last updated: September 2026 dataMechanical and spring-driven clock movements — those powered neither by AC electricity nor by battery — fall here, covering the traditional horological technology still prized in premium and heritage timepieces. Germany and Switzerland lead US supply under this heading, reflecting the concentration of high-grade mechanical clockwork manufacturing in Central Europe. The US schedule subdivides these movements at the 10-digit level by case diameter (not over 50mm at 9109902000, over 50mm at 9109904000 and 9109906000) and by unit value, so accurate measurement and valuation documentation are essential at entry.

This heading explicitly excludes both battery-powered and AC-powered movements, which are classified under heading 910910. Movements here are typically wound mechanically (spring-driven) or powered by gravity, making them characteristic of traditional mantel, wall, and tower clocks.
Both countries maintain deep industrial traditions in precision mechanical clockmaking, with established supply chains for escapements, mainsprings, and gear trains. Their movements often command premium valuations, which also affects which 10-digit line applies — 9109906000 covers movements over 50mm and over $5, a tier where European mechanical movements frequently fall.
