U.S. exports of helical springs of iron or steel (HS 732020) totaled $44.1M in July 2026.
Importers of Helical Springs of Iron or Steel paid $11.3M in duties in July 2026 — an effective duty rate of 45% on $25.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Helical springs — coiled compression, extension, or torsion springs wound from iron or steel wire — serve both automotive suspension and a wide range of industrial and consumer applications, and imports are subject to Section 232 tariffs as steel-derivative articles. The US tariff schedule separates motor vehicle suspension-grade helical springs (7320201000) from all others, then further subdivides non-automotive springs by wire cross-section diameter: under 5.1 mm (with a dedicated line for bedding and furniture use under heading 9404), 5.1 mm to under 12.7 mm, and larger gauges. Mexico and Japan are the leading suppliers, with China and Canada also prominent, reflecting both automotive OEM sourcing and broad industrial procurement.

For helical springs not used in motor vehicle suspension, the US schedule uses wire cross-section as the primary breakout: springs of wire under 5.1 mm are split between those destined for use in bedding or furniture (heading 9404 articles, line 7320205010) and all other uses (7320205020); springs of wire from 5.1 mm to under 12.7 mm fall under 7320205045; and larger-wire springs are captured in 7320205060. Accurate measurement and end-use documentation are therefore essential to correct classification.
Because helical springs are steel-derivative articles, importers should obtain mill certificates or equivalent documentation confirming the steel composition and country of melt and pour. This supports both Section 232 compliance and any USMCA origin claims for Mexico- or Canada-sourced springs. A licensed customs broker can advise on current exclusion requests or product-specific rulings that may affect duty liability.
