U.S. imports of parts of non-farm grain cleaning, sorting & milling machinery (HS 843790) totaled $3.1M in April 2026, traded with 31 countries.
Last updated: April 2026 dataWear parts, screens, rollers, and mechanical assemblies for commercial grain-cleaning, seed-sorting, and milling equipment are classified here, with the US schedule distinguishing parts of flour and grain mill machines (8437900010) from parts of other cleaning, sorting, and cereal-working machinery (8437900090). Canada leads imports under this heading, with Spain and Italy also significant — the Spanish and Italian presence reflects aftermarket supply chains tied to European OEM milling-equipment manufacturers. China's position among the top five suppliers means importers should assess Section 301 exposure at the applicable 10-digit line before entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Metal or plastic sieve frames and screens designed specifically for grain-cleaning machines are classified as parts of those machines under 8437.90, not as textile or wire-cloth products. The key is that they are identifiable as parts of a specific machine type. Woven wire cloth sold in bulk without machine-specific design would be classified differently.
CBP expects evidence that the part is dedicated to or principally used with grain-cleaning or milling machinery — OEM part numbers, technical drawings referencing the parent machine, or supplier invoices describing the part's application all strengthen the classification. Generic fasteners or bearings used across many machine types are typically classified under their own headings rather than as parts of milling machinery.
