2620.29.00.30 - Zinc content

This classification, HTS Code 2620.29.00.30, specifically addresses slag, ash, and residues that are not derived from the manufacture of iron or steel, and contain metals or their compounds, with a particular focus on their zinc content. These materials are typically byproducts of various industrial processes, such as smelting or refining, and possess a significant concentration of zinc.

Distinguishing this category from its siblings, it is important to note that while other entries under 2620.29.00 relate to the content of copper, lead, silver, or gold, this particular subheading isolates materials where zinc is the predominant or primary metallic constituent of interest for classification purposes. The classification hinges on the identification and quantification of zinc within these residual materials.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification under 2620.29.00.30 is definitive for slag, ash, and residues meeting the general criteria of Chapter 26, and specifically containing zinc in significant amounts, and not predominantly containing other specified metals at this detailed level. Practical classification will involve analytical testing to confirm the presence and primary nature of zinc.
