U.S. imports of base metal mountings, fittings & similar articles for motor vehicles (except hinges) (HS 830230) totaled $199.3M in July 2026, traded with 60 countries.
Importers of Base Metal Mountings, Fittings & Similar Articles for Motor Vehicles (Except Hinges) paid $22.6M in duties in July 2026 — an effective duty rate of 18% on $125.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataPneumatic cylinder lift-and-lower mechanisms and other non-hinge mountings designed for motor vehicles are the core articles here, with the US schedule separating pneumatic cylinders (8302303010) from other iron/steel, zinc, and aluminum fittings (8302303060) and a residual base metal line (8302306000). Mexico and Canada together lead US supply, reflecting deep automotive supply-chain integration under USMCA, where rules-of-origin compliance can affect preferential duty eligibility. Importers should confirm that articles are specifically designed for motor vehicles, as general-purpose fittings that happen to be used on vehicles may be more appropriately classified under other 8302 subheadings.

Importers typically rely on engineering drawings, OEM part numbers, or supplier declarations confirming the article is designed and marketed specifically for motor vehicle applications. General-purpose fittings that are merely used on vehicles but not specifically designed for them may not qualify and could be reclassified under 8302.49.
Articles originating in Mexico or Canada that satisfy USMCA rules of origin — including applicable tariff-shift and regional-value-content requirements — may qualify for preferential duty treatment. Given that Mexico and Canada are the leading suppliers under this heading, verifying USMCA origin compliance is a routine step for automotive importers managing landed cost.
