Last updated: April 2026 dataDisc harrows — tillage implements that use gangs of concave steel discs to break up and mix soil — are classified under a single 10-digit line (8432210000) with no further US tariff-schedule subdivision. Canada is the leading supplier, consistent with the deep integration of North American farm-equipment manufacturing under USMCA. Germany and Mexico follow as significant sources, with Czech Republic and Brazil rounding out the top five. Disc diameter, gang angle adjustability, and frame weight class are the primary specification variables that drive procurement decisions for row-crop and cover-crop applications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A disc plow (8432.10) uses individually mounted, widely spaced discs set at a steep angle to invert soil in a furrow, functioning like a moldboard plow. A disc harrow (8432.21) uses multiple discs arranged in gangs at a shallower angle to cut, mix, and level the soil surface without full inversion. The key classification test is the implement's primary tillage action — inversion versus surface incorporation.
No. Replacement disc blades and other wear parts for disc harrows are generally classified as parts of agricultural machinery under heading 8432.90, not under 8432.21, which covers complete disc harrow implements. Importers should ensure invoices clearly distinguish between complete machines and spare or replacement components to avoid misclassification.
