7901.11.00.00 - Containing by weight 99.99 percent or more of zinc

This HTS classification, 7901.11.00.00, specifically designates unwrought zinc that is exceptionally pure, containing a minimum of 99.99 percent zinc by weight. This category applies to primary zinc in its raw, unformed state, such as ingots, pigs, cakes, or granules, intended for further processing in various industries. The high purity level is a critical defining characteristic for this particular tariff line, distinguishing it from other forms of unwrought zinc.

It is crucial to differentiate this category from its sibling, 7901.12, which covers unwrought zinc that is alloyed or contains less than 99.99 percent zinc by weight. The distinction lies solely in the precise percentage of zinc content. This means that any unwrought zinc with even a slight impurity or alloying element, bringing its zinc content below the 99.99 percent threshold, would be classified under 7901.12, not 7901.11.00.00.

As this HTS code represents a leaf node, there are no further subcategories within this specific classification. Therefore, all unwrought zinc meeting the 99.99 percent or higher purity criterion falls directly under 7901.11.00.00. Classification professionals should rely on assay certificates or other verifiable documentation to confirm the precise zinc content when determining the correct tariff treatment for these high-purity zinc products.
