U.S. imports of threshing machinery (excluding combine harvester-threshers) (HS 843352) totaled $1.0M in August 2026, imported from 11 countries.
Importers of Threshing Machinery (Excluding Combine Harvester-Threshers) paid $101K in duties in August 2026, an effective tariff rate of 9.84% of the $1.0M imported — duty actually collected as a share of that value, not the published tariff schedule. Threshing Machinery (Excluding Combine Harvester-Threshers) imports of $1.0M in August 2026 ran 40% below the year-to-date monthly average of $1.7M.
Last updated: August 2026 dataStand-alone threshers that separate grain from stalks and husks without performing the reaping function are classified under a single 10-digit line (8433520000), distinguishing them from combine harvester-threshers under 843351. The United Kingdom leads US imports under this heading, with Italy and Canada also supplying equipment used in specialty-crop and small-farm operations where dedicated threshing remains practical. These machines serve niche markets — including seed-cleaning operations, organic grain producers, and developing-market export programs — where the combine's integrated approach is either cost-prohibitive or operationally unsuitable.

A machine whose primary function is threshing (separating grain from the plant) with an integrated cleaning/winnowing stage is still classified as a thresher under 843352. Machines whose sole function is cleaning or grading already-threshed grain are classified under heading 843360 (machines for cleaning, sorting, or grading seed or grain). The essential character and design intent of the machine govern.
No. Heading 843352 covers threshing machinery regardless of power source or mobility. Both PTO-driven field-portable units and stationary electrically powered barn threshers fall under 8433520000, as the heading does not subdivide by drive type or portability.
