Deformed reinforcing bars (rebar) produced by hot-rolling with ribs, grooves, or similar surface deformations are the backbone of concrete reinforcement in construction. Imports of this product are subject to Section 232 tariffs on steel, making origin and mill certification critical considerations for US buyers. Antidumping and countervailing duty orders have historically targeted deformed rebar from multiple countries, so importers should verify current order scope before contracting. Mill test reports confirming deformation geometry and yield strength are standard documentation requirements at entry.
