2620.19.60.30 - Zinc content

This HTS subheading, 2620.19.60.30, specifically classifies residues and ashes from various industrial processes, excluding those from iron and steel manufacturing, that contain significant amounts of zinc and are not primarily characterized by their copper, lead, silver, or gold content. These materials are typically by-products or waste generated from smelting, refining, or other metallurgical operations where zinc is a primary constituent or a recovered metal. Examples might include drosses from galvanizing, zinc ash from secondary zinc production, or residues from the manufacture of zinc oxide.

The key differentiator for this classification lies in the predominant metal content. While its sibling categories, 2620.19.60.10, 2620.19.60.20, 2620.19.60.40, and 2620.19.60.50, are dedicated to residues with a primary focus on copper, lead, silver, and gold respectively, this subheading is for those where zinc is the principal valuable or characterizing metal. Classification hinges on identifying the dominant metallic element by weight or economic significance within the residue.

As this is a leaf node within the HTS structure, there are no further subdivisions under 2620.19.60.30. Therefore, all residues fitting the description of containing mainly zinc, and not primarily characterized by copper, lead, silver, or gold, will be classified here. The classification is definitive at this level, meaning careful analysis of the composition of the imported or exported material is crucial to ensure correct duty assessment and trade compliance.
