2620.19.60 - Other

This category, HTS 2620.19.60, encompasses "Other" slag, ash, and residues containing arsenic, metals, or their compounds, specifically those that are not primarily zinc-containing and are not zinc dross or skimmings. These materials are derived from various industrial processes, excluding those related to the manufacture of iron or steel, and are characterized by the presence of metals or their compounds in significant quantities. The classification here is for residual materials that do not fit into more specifically defined categories within the broader group of slag, ash, and residues.

Distinguishing this category from its sibling, HTS 2620.19.30 (Zinc dross and zinc skimmings), is crucial. While both fall under the umbrella of slag, ash, and residues containing metals, HTS 2620.19.30 specifically refers to byproducts from the zinc smelting or refining process. HTS 2620.19.60, conversely, covers a wider range of residual materials where the primary metal content or origin is not specifically zinc dross or skimmings, and the material does not primarily consist of zinc.

The subcategories under HTS 2620.19.60 further refine classification based on the predominant metallic content present in these residual materials. These subdivisions, including copper content (2620.19.60.10), lead content (2620.19.60.20), zinc content (2620.19.60.30), silver content (2620.19.60.40), and gold content (2620.19.60.50), allow for precise identification of the specific metal that is a primary constituent of the residue. This detailed breakdown is essential for accurate duty assessment and statistical reporting, reflecting the varying economic value and industrial applicability of these different metallic residues.
