Overview

This classification, HTS 2620.30.00.30, specifically pertains to slag, ash, and residues, other than those originating from the manufacture of iron or steel, which contain metallic components and are characterized by a significant zinc content. These materials are typically byproducts of various industrial processes, such as smelting or refining, and their classification hinges on the predominant metal present.

The distinction between this category and its siblings lies in the primary metallic element. While HTS 2620.30.00.10 focuses on residues with copper as the dominant metal, and 2620.30.00.20 relates to those primarily containing lead, this code isolates materials where zinc is the principal metallic constituent. Similarly, it differentiates from categories focusing on silver (2620.30.00.40) or gold (2620.30.00.50) by virtue of the predominant metal identified.

As a leaf node, HTS 2620.30.00.30 has no further subcategories. Therefore, the practical classification of a material under this code will depend on an accurate assay determining that zinc is the most significant metal present in the slag, ash, or residue, after excluding those classified under the broader headings for iron and steel production byproducts. These materials often have value as a source for zinc recovery or for use in other industrial applications where their specific elemental composition is advantageous.
