U.S. exports of other springs of iron or steel (not leaf or helical) (HS 732090) totaled $17.4M in July 2026.
Importers of Other Springs of Iron or Steel (Not Leaf or Helical) paid $6.1M in duties in July 2026 — an effective duty rate of 52% on $11.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataGermany and Poland are the leading US suppliers under this residual spring heading, which captures iron and steel spring types not classified as leaf or helical — including precision hairsprings (7320901000), wire-form springs for bedding and furniture applications (7320905010), and a range of other wire and non-wire springs (7320905020 through 7320905060). The heading's catch-all nature means classification disputes often arise when a spring's geometry or function does not clearly fit the leaf or helical definitions in headings 732010 or 732020. As steel-derivative articles, these springs are subject to Section 232 tariffs, and European-origin goods may face additional trade-remedy scrutiny depending on current measures in effect.

Hairsprings are extremely fine, flat-spiral or coiled springs used in precision instruments such as clocks, watches, and measuring devices. They are specifically enumerated at 7320901000 and are distinct from the wire-form and other general-purpose springs in the remaining lines of this heading. Importers of precision instrument components should confirm whether the article meets the hairspring definition or whether it falls under a more specific instrument-parts heading.
The key question is whether the spring is wound in a true helical coil — a continuous spiral of uniform pitch around a central axis. If the geometry is helical, heading 732020 applies; irregular coils, flat spirals, volute forms, or other non-helical configurations fall to 732090. When the geometry is ambiguous, a binding ruling request to CBP provides the most defensible classification position.
