HS code for Combine harvester: 8433.51
Combine harvester-threshers.
Classification of combine harvester under HS 8433.51
Combine harvesters are classified under HS code 843351. This code is situated within Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8433 specifically addresses harvesting or threshing machinery, including straw or fodder balers and grass or hay mowers. The subheading 843351 is dedicated exclusively to "combine harvester-threshers." These are complex, integrated machines designed to perform multiple agricultural operations—reaping, threshing, and winnowing—in a single continuous process. The classification is based on the integrated function of the machine. Whether the unit is self-propelled or designed to be towed by a tractor, if it performs the combined functions of harvesting and threshing, it remains under this specific code. Accurate classification is essential for agricultural equipment importers to comply with regional safety standards and to benefit from duty exemptions often applied to food production machinery. The technical definition excludes machines that only perform one of these tasks, such as simple mowers or standalone threshing machines, which are classified under other subheadings within the same heading.

Codes often confused with 8433.51
Common mistake. This code is often confused with 843359, which covers other harvesting machinery like cotton pickers, sugar cane harvesters, or forage harvesters that do not perform the specific threshing function. It may also be confused with 8432, which covers machinery for soil preparation like plows or harrows. It is important to note that parts for these machines should be classified under 843390 rather than the code for the complete machine.

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).
