HS Code 8433.51 – Combine harvester-threshers
HS code 8433.51 is the 6-digit subheading for combine harvester-threshers. It is used for grain combines, corn combines, soybean combines, rice combines and axial-flow combines.
What HS 8433.51 covers
This category is dedicated to combine harvester-threshers, often simply referred to as 'combines.' These are highly complex and efficient machines that perform multiple harvesting operations—reaping, threshing, and winnowing—in a single pass. They are essential for large-scale grain and seed crop production globally, significantly reducing labor and time. Importers are typically large commercial farms, agricultural cooperatives, and machinery rental companies in major agricultural regions, seeking to maximize efficiency and yield. Exporters are predominantly countries with advanced agricultural machinery manufacturing capabilities, often incorporating cutting-edge technology. Key considerations include header width, grain tank capacity, engine power, and integration with precision farming technologies like GPS and yield mapping. The trade in combines is a significant indicator of global agricultural investment and modernization, reflecting the drive for increased productivity.

Codes often confused with 8433.51
Common mistake. Can be confused with other harvesting machinery (843359) if the "combine" function (multiple operations in one machine) is not recognized, or with threshing machinery (843352) if only the threshing aspect is considered.
Top exporters and importers of HS code 843351, 2025
In 2025, the largest exporter of HS code 843351 in UN Comtrade data was the United States, with 30% of world exports; the largest importer in UN Comtrade data was Canada, with 23% of world imports.

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).
