2620.30.00.10 - Copper content

This HTS classification, 2620.30.00.10, specifically covers slag, ash, and residues, other than those originating from the manufacture of iron or steel, which are characterized by their significant copper content. These materials are typically byproducts of metallurgical processes where copper is a primary component of the recovered metals or is present in substantial quantities within the waste material. This category encompasses a wide range of materials, including fly ash, furnace dust, and processing residues, provided that copper is the predominant metal or metal compound present for classification purposes.

It is crucial to distinguish this category from its siblings, which classify similar residual materials based on their principal metal content. While other subheadings within 2620.30.00 might address residues with a primary focus on lead, zinc, silver, or gold, this specific subheading is reserved for those where copper is the dominant element determining its classification. The determination of "copper content" will rely on established analytical methods and customs guidelines to ensure accurate classification.

As this is a leaf node, there are no further subcategories branching from 2620.30.00.10. Therefore, classification within this heading relies solely on identifying the material as a slag, ash, or residue (not from iron/steel production) and confirming that copper is the primary metal of significance. Practical examples might include copper smelting dross, copper refining slimes, or residues from copper plating baths, all of which would be classified here if copper is the defining characteristic.
