2616.90.00.30 - Zinc content

This classification, HTS 2616.90.00.30, specifically covers ores, slag, and ash that are not precious metals themselves but contain zinc as a primary valuable component. This category is designated for mineral products where zinc is the principal metal of economic interest, and these materials fall within Chapter 26, which deals with ores, slag, and ash.

It is crucial to distinguish this classification from its siblings. While all fall under "Other precious metal ores and concentrates," HTS 2616.90.00.30 is exclusively for those where zinc is the dominant metal content, as opposed to copper (2616.90.00.10), lead (2616.90.00.20), gold (2616.90.00.40), or other precious metals (2616.90.00.50). The determination for classification here hinges on the presence and significance of zinc as the principal metal, differentiating it from ores where other metals are of primary value.

As this is a leaf node, there are no further subcategories under this specific HTS code. Therefore, classification within HTS 2616.90.00.30 is definitive based on the material being an ore, slag, or ash with significant zinc content, and not primarily containing other precious metals as defined by the preceding sibling categories. The focus remains on identifying and classifying mineral products where zinc is the key element of trade or economic interest within this broader grouping.
