HS code 8433.90 is the 6-digit subheading for harvesting machinery, parts, including parts of threshing machinery, straw or fodder balers and grass or hay mowers. It is used for combine harvester blades, baler knotters, mower cutting bars, thresher concaves and harvester belts.
What HS 8433.90 covers
This HS code covers the essential components and spare parts for a wide array of harvesting machinery, ranging from combine harvesters to balers and mowers. It's a critical category for maintaining the operational efficiency and longevity of agricultural equipment globally. Farmers, agricultural cooperatives, and machinery repair shops are the primary consumers, relying on these parts to minimize downtime during crucial harvesting seasons. Manufacturers of agricultural machinery, as well as specialized parts suppliers, are key players in the export market. The trade in these parts is influenced by the global demand for food, the mechanization level of agriculture in different regions, and the need for durable, high-performance components. Understanding compatibility and quality standards is paramount for both importers and exporters.

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).
