Free-cutting non-alloy steel bars and rods — not further worked than hot-rolled, hot-drawn, or equivalent — that do not fall into the coil or deformed-bar categories are classified here, covering straight bar stock used extensively in automatic screw machine production of fasteners, fittings, and precision turned parts. The added sulfur or lead content that defines free-cutting grades must be confirmed by mill certification, as misclassification into a standard carbon bar heading can expose importers to incorrect duty treatment or antidumping order scope issues. Section 232 tariffs apply, and the relatively niche demand profile means supply is concentrated among a smaller number of specialty mills.
