Importers of Hot-Rolled Iron & Non-Alloy Steel Flat Products, Under 600mm Wide, 4mm+ Thick paid $3.4M in duties in April 2026 — an effective duty rate of 50% on $6.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataWidth below 600mm combined with a thickness of 4mm or more defines this narrow, heavy-gauge hot-rolled strip category, which is commonly used in the production of agricultural equipment components, chain links, and certain structural profiles. The dimensional thresholds — both width and thickness — are the operative classification criteria, and a product that straddles the 600mm width boundary or the 4mm thickness floor may fall into an adjacent heading. Section 232 tariffs apply to this product as a steel mill article, and origin-specific antidumping orders may also be in scope.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The 4mm minimum thickness separates this heading from thinner narrow strip, which falls into a separate 'not elsewhere specified' category. Thickness is measured at the thinnest point of the cross-section, and mill test reports or physical measurement at the port may be used to verify compliance with the threshold.
Mill test certificates (MTCs) are the standard documentation, as they record the nominal and actual width, thickness, and mechanical properties of each coil or bundle. Customs authorities may request MTCs during examination, and discrepancies between declared dimensions and MTC data can trigger reclassification or penalty proceedings.
