Last updated: April 2026 dataTrack-laying bulldozers and angledozers — the crawler-mounted earthmoving workhorses of construction, mining, and land clearing — are split at the US tariff level between new units (8429110010) and used units (8429110090), a distinction that affects both duty treatment and admissibility documentation. Japan is the dominant US import source, driven by the global market positions of Komatsu and Caterpillar's Japanese manufacturing operations, with Brazil and South Korea also significant suppliers. Used equipment imports require additional scrutiny for soil and organic material contamination under USDA APHIS quarantine requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
USDA APHIS requires that used soil-moving equipment be free of soil, plant material, and other organic debris that could harbor pests or plant diseases. Importers must ensure equipment is cleaned and inspected before arrival; CBP agriculture specialists may inspect and hold shipments at the port of entry if contamination is found. Some origins require a phytosanitary certificate or specific cleaning certification. Failure to comply can result in treatment, re-exportation, or destruction of the equipment.
The US schedule separates new track-laying bulldozers (8429110010) from used ones (8429110090). 'Used' generally means the equipment has been placed in service, not merely that it is not in original packaging. Importers of used equipment should be prepared to document the machine's service history, and should note that used heavy equipment may also be subject to EPA emission standard verification if it will be operated in the US.
