Product classification
HS code for Threshing machine: 8433.52
Threshing machinery, other than combine harvester-threshers.
Classification of threshing machine under HS 8433.52
A threshing machine is classified under HS code 843352. This classification is part of the broader category for harvesting or threshing machinery within Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8433 covers machines for harvesting, threshing, or baling agricultural produce. While combine harvesters (which both harvest and thresh) are classified under 843351, the subheading 843352 is dedicated specifically to threshing machinery that operates as a standalone unit. These machines are designed to separate grain from the stalks and husks after the crop has been harvested. The classification is based on the mechanical function of the machine and its specific agricultural application. Whether the machine is stationary or mobile, if its primary purpose is threshing and it is not a combine harvester, it remains under this code.

Codes often confused with 8433.52
Common mistake. The most frequent misclassification is with HS code 843351, which covers combine harvester-threshers. The distinction lies in whether the machine performs the cutting/reaping and threshing simultaneously (843351) or just the threshing (843352). Another common error is using HS code 8437, which covers machines for cleaning, sorting, or grading seed, grain, or dried leguminous vegetables. While threshers separate grain from the plant, 8437 machines are used for post-threshing refinement and cleaning.

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).
