U.S. imports of Chassis Fitted with Engines for Motor Vehicles (SITC 78410) totaled $13.2M in September 2026, imported from 12 countries.
Importers of Chassis Fitted with Engines for Motor Vehicles paid $1.9M in duties in September 2026, an average duty rate of 14.48% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Chassis Fitted with Engines for Motor Vehicles imports of $13.2M in September 2026 ran 32% above the year-to-date monthly average of $10.0M.
Last updated: September 2026 dataEngine-fitted chassis — the rolling powertrain platforms supplied before bodywork is added — serve as critical intermediate inputs for bus, truck, and specialty vehicle manufacturers that source bodies separately from chassis. Classification as a chassis rather than a complete vehicle depends on the absence of a body at time of importation; adding even a cab can shift the classification to a complete vehicle, a distinction CBP scrutinizes closely. Importers assembling vehicles domestically from imported chassis should also evaluate whether the finished product triggers NHTSA compliance obligations at the chassis stage.

CBP applies the 'essential character' test: a chassis fitted with an engine but lacking a body or cab is generally classified as a chassis. However, if the chassis arrives with a cab attached or with bodywork that gives it the essential character of a complete vehicle, it will be classified as a complete motor vehicle. Importers should review the configuration at time of importation carefully and consider a binding ruling if the line is unclear.
Incomplete vehicles — including chassis — are subject to NHTSA's incomplete vehicle regulations, which require the chassis manufacturer to provide a statement of conformity with applicable FMVSS to the final-stage manufacturer. The final-stage manufacturer completing the vehicle bears responsibility for overall FMVSS compliance. Importers acting as final-stage manufacturers must understand these obligations before the chassis enters commerce.
