Last updated: August 2026 dataAutomatic-winding watch movements — mechanical calibers that harness the wearer's motion via a rotor to maintain mainspring tension — are classified here, with Switzerland the dominant US import source and Thailand a significant secondary supplier. The US schedule splits this heading by jewel count: movements with more than 17 jewels (9108204000) and those with 17 or fewer (9108208000), a distinction that correlates broadly with movement complexity and value tier. Automatic movements are the hallmark of traditional Swiss watchmaking and command premium positioning in the US market; importers should confirm jewel count from the manufacturer's caliber specification sheet, as this parameter directly determines the applicable 10-digit line.

For HTS classification purposes, the jewel count refers to functional jewels — those serving as bearings or impulse surfaces within the movement — not decorative stones added for aesthetic purposes. Importers should request a caliber specification sheet from the manufacturer that explicitly states the number of functional jewels to support the correct line selection between 9108204000 and 9108208000.
CBP typically expects a commercial invoice identifying the caliber reference, jewel count, and unit value; a packing list; and, for Swiss-origin goods, a certificate of origin if preferential treatment is claimed. For high-value movements, a manufacturer's technical data sheet confirming the movement is complete and assembled and specifying jewel count is advisable to preempt classification or valuation queries at entry.
