U.S. imports of self-loading or self-unloading agricultural trailers & semi-trailers (SITC 78621) totaled $8.4M in July 2026, traded with 10 countries.
Importers of Self-Loading or Self-Unloading Agricultural Trailers & Semi-Trailers paid $34K in duties in July 2026 — an effective duty rate of 11% on $302K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAgricultural self-loading and self-unloading trailers — including forage wagons, grain carts, and silage trailers equipped with conveyors, augers, or hydraulic tipping mechanisms — are purpose-built for farm operations and classified separately from general-purpose cargo trailers. The agricultural end-use designation is a key classification criterion; a trailer with self-loading capability used outside of farming contexts may be pulled into a different SITC heading. Importers should verify that the trailer's design and documentation clearly establish agricultural purpose, as this affects both classification and potential eligibility for agricultural equipment duty treatment.

Customs authorities typically look for manufacturer specifications, product literature, and commercial invoices that explicitly describe the trailer's design for agricultural use — such as field harvesting, grain handling, or silage transport. Generic descriptions of 'self-loading capability' without agricultural context may result in reclassification under a broader trailer heading.
Agricultural trailers themselves do not typically require USDA APHIS import permits, but if a used trailer carries soil, plant material, or organic residue, APHIS may require cleaning and inspection at the port of entry to prevent introduction of pests or plant diseases. New equipment generally clears without such requirements.
