U.S. imports of semifinished iron or nonalloy steel — 0.25% carbon or more (HS 720720) totaled $293K in April 2026, traded with 11 countries.
Importers of Semifinished Iron or Nonalloy Steel — 0.25% Carbon or More paid $98K in duties in April 2026 — an effective duty rate of 35% on $276K in dutiable value, based on actual customs collections rather than the published tariff schedule. Semifinished Iron or Nonalloy Steel — 0.25% Carbon or More imports of $293K in April 2026 ran 66% below the year-to-date monthly average of $858K.
Last updated: April 2026 dataMedium- and high-carbon semifinished steel products — billets, blooms, and slabs containing 0.25% or more carbon by weight — serve specialty rolling and forging applications where hardness, wear resistance, and hardenability are critical, including rail, tool steel precursors, and spring steel. The US schedule provides four 10-digit subdivisions (7207200025, 7207200045, 7207200075, 7207200090) based on cross-section geometry, mirroring the low-carbon structure but for higher-carbon grades. Brazil leads US supply, with Canada and Mexico also significant. Section 232 tariffs apply, and the carbon threshold is the critical classification boundary with the sub-0.25% headings.

A mill test certificate (MTC) from the producing mill, showing the heat analysis or product analysis with carbon content expressed as a weight percentage, is the standard supporting document. CBP may request the MTC at entry or during a post-entry audit. If the certified carbon content is close to the 0.25% boundary, importers should also retain ladle analysis records, as product analysis can vary slightly from heat analysis.
All four 10-digit lines under 7207.20 carry the same base HTS rate, so the subdivision does not change the column 1 duty. However, the geometry lines matter for AD/CVD scope determinations, which often reference specific cross-section descriptions. Importers should ensure the declared 10-digit line matches the actual product dimensions, as misclassification at the statistical suffix level can complicate scope analysis and draw CBP scrutiny.
