U.S. imports of Iron & Nonalloy Steel Semifinished Rectangular Shapes (Under 0.25% Carbon) (SITC 67262) totaled $226.0M in August 2026, imported from 15 countries.
Importers of Iron & Nonalloy Steel Semifinished Rectangular Shapes (Under 0.25% Carbon) paid $103.3M in duties in August 2026, an average duty rate of 42.08% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Iron & Nonalloy Steel Semifinished Rectangular Shapes (Under 0.25% Carbon) imports of $226.0M in August 2026 ran 35% above the year-to-date monthly average of $167.4M.
Last updated: August 2026 dataRectangular cross-section semifinished products of iron or nonalloy steel with under 0.25% carbon — where the width exceeds twice the thickness, distinguishing slabs from square billets — are the primary rolling-mill feedstock for flat-rolled products such as hot-rolled coil and plate. The geometry criterion is the key classification boundary: a product that is rectangular but does not meet the width-to-thickness ratio falls under the square-section heading instead. Section 232 tariffs apply, and slab dimensions and carbon content must be certified by the producing mill.

Slabs have a rectangular cross section where the width is at least twice the thickness, making them the feedstock for flat-rolled products. Blooms and billets with a square or near-square cross section (width less than twice the thickness) fall under the square-section semifinished heading. Dimensional mill certificates are the authoritative reference.
Yes. In addition to standard commercial invoice and packing list requirements, steel slab imports typically require a mill certificate showing chemical composition (to confirm carbon content below 0.25% and absence of alloy additions above threshold levels) and, where applicable, a Section 232 product exclusion or quota documentation if the importer is relying on an exemption.
