Last updated: April 2026 dataNarrow hot-rolled alloy steel N.E.S. flat — under 600 mm wide — covers strip and bar-in-coil formats used in spring manufacturing, tool blanks, chain components, and specialty mechanical parts where specific alloying provides hardness, toughness, or fatigue resistance not achievable with plain carbon steel. The sub-600 mm width places this product in the narrow flat-rolled bracket, which is classified separately from wide coil and plate. Section 232 tariffs apply, and the N.E.S. qualifier requires chemical composition documentation to confirm the product does not belong to a more specifically defined alloy steel category.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Spring manufacturers, chain and conveyor component producers, hand-tool fabricators, and automotive parts suppliers are typical buyers. The narrow width suits roll-forming, blanking, and progressive-die stamping operations that process strip rather than wide sheet.
Not automatically. Boron steel qualifies as alloy steel only if the boron content meets the minimum threshold defined in the applicable nomenclature notes. Below that threshold, the product may classify as carbon steel strip. Importers should obtain a certified ladle analysis and compare it against the schedule's alloy steel definition before filing entry.
