U.S. exports of Iron & Nonalloy Steel Semifinished Products (0.25% Carbon or More) (SITC 67270) totaled $549K in August 2026.
Importers of Iron & Nonalloy Steel Semifinished Products (0.25% Carbon or More) paid $96K in duties in August 2026, an average duty rate of 40.82% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Iron & Nonalloy Steel Semifinished Products (0.25% Carbon or More) imports of $244K in August 2026 ran 62% below the year-to-date monthly average of $641K.
Last updated: August 2026 dataMedium- and high-carbon nonalloy steel semifinished products — billets, blooms, and slabs containing at least 0.25% carbon by weight — serve as feedstock for demanding applications including rail, spring steel, wire rod for tire cord, and forged components. The elevated carbon content is the defining classification criterion separating these products from the lower-carbon semifinished headings, and it also signals different downstream heat-treatment and mechanical-property requirements. Section 232 tariffs apply, and mill certifications confirming carbon content at or above the 0.25% threshold are essential for correct entry.

Steel wire rope and tire cord producers, spring manufacturers, rail producers, and forging operations for agricultural and construction equipment are the primary consumers. The higher carbon content enables the hardness and tensile strength these applications require, and buyers often specify narrow carbon ranges within the 0.25%-and-above band.
Classification follows the actual certified chemical composition on the mill certificate. A product testing at exactly 0.25% carbon falls under this heading (not under 0.25%), while one testing at 0.249% falls under the lower-carbon headings. Given the classification consequence, importers should request heat-specific certifications rather than relying on nominal grade designations.
