Importers of Diesel-Powered Road Tractors for Semi-Trailers paid $128.2M in duties in August 2026, an effective tariff rate of 16.75% of the $765.8M imported — duty actually collected as a share of that value, not the published tariff schedule.

Last updated: August 2026 dataRoad tractors (semi-truck prime movers) powered solely by compression-ignition (diesel or semi-diesel) engines are classified here, with the US schedule further divided by gross vehicle weight and condition: new units under 36,287 kg GVW (8701210015), new units over that threshold (8701210045), and used tractors (8701210080). Mexico and Canada are the dominant suppliers, with North American truck manufacturing deeply integrated under USMCA, making preferential tariff treatment a realistic consideration for qualifying units. European producers — Italy, Sweden, and the Netherlands — supply a smaller but notable share, particularly for specialized heavy-haul configurations.

The 36,287 kg (approximately 80,000 lb) GVW breakpoint separates 8701210015 (lighter new tractors) from 8701210045 (heavier new tractors) for statistical and tariff purposes. Importers must confirm the manufacturer's stated GVW rating — not the actual loaded weight — to determine the correct 10-digit line. Misclassification between these two lines is a common audit finding for commercial truck importers.
CBP generally considers a vehicle 'used' if it has been previously registered, titled, or operated on public roads, regardless of mileage or age. Demonstrator units or pre-delivery inspection (PDI) vehicles that have never been registered may still qualify as new. Importers of used tractors should also be aware that EPA and DOT compliance requirements for used vehicles can differ from those applicable to new imports.
