HS code for Thresher: 8433.52
Threshing machinery, other than combine harvester-threshers.
Classification of thresher under HS 8433.52
Threshing machinery, excluding combine harvester-threshers, is classified under HS code 8433.52. This classification is situated within Chapter 84, heading 8433, which covers harvesting or threshing machinery, including straw or fodder balers and grass or hay mowers. While combine harvesters (which both harvest and thresh) are classified under 8433.51, standalone threshing machines are assigned to 8433.52. These machines are used to separate grain from the stalks and husks after the crop has been harvested. The classification covers a wide range of sizes, from small, hand-fed units to large, tractor-driven stationary threshers. The primary criterion is that the machine's function is limited to threshing or that it is presented as a separate unit from the harvesting mechanism. If the machine also cleans or grades the grain, it may still remain here if the threshing function is the principal use, though machines solely for cleaning seeds or grain are classified under 8437. The distinction is based on the agricultural stage: 8433 is for field harvesting and threshing, while 8437 is for post-harvest industrial processing of the grain. Importers should verify if the machine is a "combine" (8433.51) or a standalone thresher (8433.52) to ensure correct duty application.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
