Tedders, rakes, windrowers, and swath turners — the post-cutting haying equipment that conditions and arranges cut forage for drying — are classified under a single 10-digit line (8433300000), reflecting their unified treatment in the US schedule. Germany leads US imports, consistent with its dominant position in European precision haying-equipment manufacturing, with France and Italy also notable sources. Importers should confirm that a machine's primary function is post-cut forage handling rather than cutting, as mowing functions shift classification to heading 843320.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Self-propelled windrowers that both cut and condition forage are generally classified under heading 843320 (mowers) or 843351 (combine-type harvesters) depending on their design, rather than 843330, which is reserved for haying machines that do not perform cutting. A pull-type or tractor-powered rake or tedder with no cutting function belongs in 843330. Classification of combination cut-and-condition machines should be confirmed with a licensed customs broker.
As of current schedules, haying machines under 843330 are not subject to Section 232 or Section 301 tariffs. However, importers should verify the current tariff treatment at the time of entry, as trade-remedy orders can change, and confirm the correct country of origin when equipment is assembled from components sourced in multiple countries.
