U.S. imports of Semifinished Iron or Nonalloy Steel — Low Carbon, Rectangular Cross-Section, Width at Least Twice Thickness (HS 720712) totaled $226.0M in August 2026, imported from 15 countries.
Importers of Semifinished Iron or Nonalloy Steel — Low Carbon, Rectangular Cross-Section, Width at Least Twice Thickness 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. Semifinished Iron or Nonalloy Steel — Low Carbon, Rectangular Cross-Section, Width at Least Twice Thickness imports of $226.0M in August 2026 ran 35% above the year-to-date monthly average of $167.4M.
Last updated: August 2026 dataSlabs and wide rectangular billets with less than 0.25% carbon — where the cross-section width is at least twice the thickness — are the dominant feedstock for flat-rolled steel production, feeding hot strip mills that produce coil, sheet, and plate. The US schedule subdivides this heading into two 10-digit lines based on whether the width-to-thickness ratio is less than four times (7207120010) or four times or greater (7207120050), a distinction relevant to slab versus wide-slab classification. Brazil leads US supply under this heading, with Mexico and Japan also significant. Section 232 tariffs apply.

The subdivision at the 4:1 width-to-thickness ratio distinguishes conventional rectangular billets (narrower profile) from true slabs (wider, flatter profile). This matters commercially because slabs feed hot strip mills for flat-rolled products, while narrower rectangular sections may feed different rolling configurations. The distinction can also affect AD/CVD scope determinations, which sometimes reference specific dimensional thresholds.
Importers should verify whether any antidumping or countervailing duty orders on steel semifinished products from Brazil are currently in effect, as the scope of such orders can include slabs. Section 232 tariffs also apply. Accurate mill certificates documenting carbon content and cross-section dimensions are essential to support both the HTS classification and any AD/CVD scope analysis.
