U.S. imports of electric motor-powered winches and capstans (HS 842531) totaled $12.7M in April 2026, traded with 28 countries.
Importers of Electric Motor-Powered Winches and Capstans paid $1.0M in duties in April 2026 — an effective duty rate of 12% on $8.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Electric Motor-Powered Winches and Capstans imports of $12.7M in April 2026 ran 21% below the year-to-date monthly average of $16.1M.
Last updated: April 2026 dataElectric winches and capstans serve critical load-pulling and line-tensioning roles across marine, offshore, logging, and heavy industrial sectors, and their classification under 842531 turns specifically on the electric motor drive — distinguishing them from hydraulic or manual variants. All US imports enter under tariff line 8425310100, and Chinese-origin goods face Section 301 exposure, a meaningful cost factor given China's dominant position as the leading supplier. Thailand and Canada are also notable sources. Buyers should verify motor voltage, rated line pull, and drum capacity specifications, as these affect both classification confidence and end-use compliance.

Both capstans and winches are covered by 842531 when powered by electric motors. A capstan is a vertical-axis rotating drum used primarily for hauling rope or cable, while a winch typically has a horizontal drum for winding cable under load. The HTS does not separate them at the 10-digit level; both classify under 8425310100 provided they are electrically driven.
To claim USMCA preferential treatment on goods from Canada, importers must have a valid certification of origin (self-certified by the exporter, producer, or importer) that demonstrates the product meets the applicable tariff-shift or regional-value-content rule of origin. Retaining supporting production records and bill-of-materials documentation is strongly recommended in case of a CBP audit.
