Last updated: August 2026 dataA critical suspension component for commercial vehicles and light trucks, iron and steel leaf springs are subject to Section 232 tariffs as steel-derivative articles, making origin and material certification central to landed-cost calculations. The US schedule subdivides this heading by vehicle weight class and leaf thickness — notably separating motor vehicle suspension springs for vehicles of four metric tons or less (7320103000) from heavier-duty applications, and distinguishing leaves of 1.6 mm or more thickness (7320106015) from other configurations. Mexico and Canada are the leading suppliers, reflecting deep integration with North American automotive supply chains, with China and Japan also significant sources.

The US tariff schedule breaks out leaf springs for motor vehicle suspension by the gross vehicle weight rating of the intended vehicle. Springs for vehicles of four metric tons or less classify under 7320103000, while heavier-duty vehicle suspension springs are further split by leaf thickness — leaves of 1.6 mm or more thickness under 7320106015, and other vehicle suspension springs under 7320106060. Non-vehicle-suspension leaf springs have their own parallel lines (7320109015 and 7320109060). Misclassification between these lines is a common audit finding.
Mexico-origin leaf springs may qualify for preferential tariff treatment under USMCA, provided the goods meet the applicable rules of origin, including any steel melt-and-pour requirements. However, Section 232 tariff exposure for steel-derivative articles is a separate consideration that can apply regardless of FTA eligibility, so importers should confirm both the origin qualification and any applicable trade-remedy status with a licensed customs broker.
