Lead Oxides (Excluding Lead Monoxide)

Beyond lead monoxide, the US tariff schedule recognizes lead suboxide (leady litharge, 2824901000), red lead and orange lead (2824902000), and residual lead oxides under two NESOI lines (2824905000 and 2824909000). Red lead (Pb₃O₄) has historically been used in corrosion-inhibiting primers and glass manufacturing, while lead suboxide is a key intermediate in lead-acid battery paste formulation. Italy and Mexico lead US supply under this heading. As with all lead compounds, importers must account for TSCA reporting requirements and applicable hazardous-material transport regulations.
