U.S. imports of hot-worked iron or nonalloy steel u-sections, 80 mm or more high (HS 721631) totaled $2.3M in April 2026, traded with 12 countries.
Importers of Hot-Worked Iron or Nonalloy Steel U-Sections, 80 mm or More High paid $885K in duties in April 2026 — an effective duty rate of 43% on $2.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataSubject to Section 232 tariffs on steel imports, hot-rolled, drawn, or extruded U-sections of iron or nonalloy steel with a height of 80 mm or more classify under a single 10-digit line (7216310000). These structural channel sections are widely used in construction framing, industrial racking, and machinery bases. Mexico is the leading US import source, with Germany and Japan also significant suppliers. Importers should be aware that Section 232 steel tariffs apply broadly to this product, though country-specific exclusions or quota arrangements may affect the effective duty for certain origins.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes, Section 232 tariffs apply to steel U-sections under this heading. Country-specific exemptions, quota arrangements, and product exclusions have been granted and modified over time. Importers should check the most current Commerce Department and CBP guidance at the time of entry to determine whether a specific origin qualifies for an exemption or quota-based treatment.
In US tariff practice, U-sections and channel sections are effectively the same structural shape — a web with two parallel flanges — and are classified together under heading 7216. The key classification variables are the height (80 mm or more for this heading), the alloy content (nonalloy steel here), and the production method (hot-worked). Cold-formed channel sections would classify elsewhere in Chapter 72.
