2824.90.10.00 - Lead suboxide (leady litharge)

This HTS category, 2824.90.10.00, specifically classifies lead suboxide, often referred to as leady litharge. Lead suboxide is a distinct compound of lead and oxygen, characterized by a lower oxidation state of lead compared to pure lead monoxide (litharge). It is typically encountered as a powder or granular material and finds application in various industrial processes, including its use as a component in certain types of batteries and as a pigment.

This classification is distinguished from its sibling, 2824.90.20.00, which covers red lead and orange lead. Red lead (Pb3O4) and orange lead are specific lead oxides with different chemical compositions and color properties, often used in paints, ceramics, and glass manufacturing. The "Other" category at this level, 2824.90.50.00, is a residual category for lead oxides not otherwise specified.

As a leaf node, 2824.90.10.00 has no further subcategories. Classification into this specific code relies on the precise chemical identification of the material as lead suboxide. When determining classification, customs officers will look for evidence of this specific chemical compound, distinguishing it from other lead oxides by its unique oxygen content and lead oxidation state.
