Electrically Operated Clock Movements, Complete & Assembled imports of $24K in August 2026 ran 43% below the year-to-date monthly average of $42K.
Last updated: August 2026 dataSubject to Section 301 tariffs given China's dominant role as the primary supplier, these complete, assembled clock movements are subdivided at the 10-digit level by power source (AC-only vs. battery), movement size (over or not over 50mm), and unit value (not over or over $5), creating a notably granular classification matrix. Alarm clock movements are separated from general clock movements across lines such as 9109100500 and 9109102010, while opto-electronic battery movements occupy their own line (9109105020). Thailand and Hong Kong are secondary sources, with Denmark and Taiwan also appearing in the supplier mix. Importers should verify the correct combination of power type, case diameter, and declared value before filing, as misclassification across the eleven available 10-digit lines is a common audit trigger.

The US tariff schedule separates alarm clock movements into their own set of 10-digit lines (e.g., 9109100500, 9109102010, 9109103010, 9109103020, 9109104020), while non-alarm clock movements are classified under separate lines such as 9109105020, 9109107010, 9109107020, 9109107030, 9109108010, and 9109109000. The split then further depends on power source (AC-only vs. battery), movement size relative to 50mm, and unit value relative to $5.
The three variables that drive 10-digit classification — power source (AC vs. battery), movement diameter (not over 50mm vs. over 50mm), and unit value (not over $5 vs. over $5) — must all be correctly declared simultaneously. Importers frequently err by applying a single variable in isolation or by misidentifying the measurement threshold, which can shift a shipment across multiple tariff lines with different duty rates.
