Standard International Trade Classification
U.S. exports of Parts for Harvesting, Threshing, Mowing & Produce-Cleaning Machinery (SITC 72129) totaled $70.9M in August 2026.
Importers of Parts for Harvesting, Threshing, Mowing & Produce-Cleaning Machinery paid $5.2M in duties in August 2026, an average duty rate of 16.76% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Parts for Harvesting, Threshing, Mowing & Produce-Cleaning Machinery imports of $30.9M in August 2026 ran 39% below the year-to-date monthly average of $50.8M.
Last updated: August 2026 dataReplacement and service parts for the full range of harvesting, threshing, mowing, and agricultural produce-cleaning and grading equipment are consolidated under this residual parts heading, making correct parent-machine identification essential for accurate classification. Parts that are identifiable as suitable for use solely or principally with a specific machine type generally follow the classification of that machine, but generic components (bearings, belts, fasteners) may be classified elsewhere under their own material-specific headings. Supply-chain managers sourcing aftermarket parts for combine headers, forage harvesters, or packing-line sorters should confirm part-specific classification with a broker, as misclassification of high-value components is a common compliance gap.

A component qualifies as a part here when it is identifiable as designed solely or principally for harvesting, threshing, mowing, or produce-cleaning machinery. General-purpose items — standard bearings, V-belts, or fasteners — are typically classified under their own headings regardless of their intended use. Detailed engineering drawings or OEM part numbers help substantiate a parts classification claim.
Duty treatment depends on the tariff classification of the part itself, not on whether it is OEM or aftermarket. Both are assessed under the same heading if they meet the same classification criteria. However, aftermarket parts may face additional scrutiny if their country of origin differs from the original equipment manufacturer's country, particularly where trade-remedy measures apply to specific component types.
