Overview
This classification covers zinc dross and zinc skimmings, which are byproducts generated during the smelting, refining, or processing of zinc. Zinc dross typically refers to a molten residue that forms on the surface of molten zinc, containing impurities and zinc oxide. Zinc skimmings are similar in nature, often collected from the surface of hot-dip galvanizing baths or other zinc-containing melts, and also consist of zinc, zinc oxide, and other metallic or non-metallic impurities. These materials are generally recovered for their zinc content and can be further processed for recycling.
This particular subheading, 2620.19.30.00, is distinguished from its sibling category, 2620.19.60, by the specific nature of the zinc-containing residues. While both fall under "other" residues containing mainly zinc, this subheading is reserved for the direct classification of zinc dross and zinc skimmings. The sibling category would encompass other zinc-bearing residues not specifically defined as dross or skimmings, potentially including different forms of slag or ash derived from zinc processing that do not fit the precise definition of dross or skimmings.
As this is a leaf node, there are no further subcategories. Classification within this heading is determined by the precise identification of the material as either zinc dross or zinc skimmings, based on its origin and physical characteristics from zinc manufacturing or processing operations.
