U.S. imports of Motor Vehicle Gasoline Engines and Engine Parts (NAICS 336310) (NAICS 336310) totaled $1.9B in August 2026, imported from 109 countries.
Importers of Motor Vehicle Gasoline Engines and Engine Parts (NAICS 336310) paid $104.8M in duties in August 2026, an average duty rate of 5.55% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataAt the 6-digit NAICS level, this code captures establishments primarily engaged in manufacturing gasoline engines for passenger cars, light trucks, and heavy-duty vehicles, as well as the discrete parts — pistons, valves, camshafts, and fuel injectors — that feed both OEM assembly lines and the aftermarket. Engine parts trade is heavily influenced by Section 232 tariff measures on automotive components, and the integrated North American production network means that many parts cross the US-Canada or US-Mexico border multiple times before final assembly. Accurate HTS classification by engine type and displacement is essential for correct duty calculation and trade-remedy applicability.

Remanufactured engine parts may be classified under the same HTS subheadings as new parts, but CBP may scrutinize the condition and processing of the goods. Additionally, some remanufactured automotive parts are subject to core return requirements and may have different valuation considerations. Consulting a licensed customs broker is advisable for remanufactured goods.
As OEMs commit to electrification timelines, demand for gasoline engine components is expected to plateau and eventually decline for passenger vehicles, though commercial and industrial engine segments may sustain demand longer. Importers and distributors should factor product lifecycle risk into sourcing contracts and inventory strategies.
