2616.10.00.30 - Zinc content

This HTS category, 2616.10.00.30, specifically classifies silver ores and concentrates where the primary identifying element for tariff purposes is the presence of zinc. These are typically ores that contain silver as a principal metal, but also contain significant amounts of zinc, requiring specific classification to accurately reflect their composition and potential value. The "Zinc content" designation signifies that the classification is driven by the zinc component alongside the silver.

It is crucial to differentiate this category from its siblings. While all fall under "Silver ores and concentrates," 2616.10.00.10 and 2616.10.00.20 are distinguished by the presence of copper or lead content, respectively. Similarly, 2616.10.00.40 and 2616.10.00.80 focus on silver content and gold content, respectively, as the dominant or key characteristic. This category is for those where zinc is the defining trace or secondary metal that dictates its specific tariff treatment.

As a leaf node, 2616.10.00.30 has no further subdivisions. Therefore, classification into this code relies on a direct assessment of the ore or concentrate's composition. Importers and exporters should consult assay reports and other technical documentation to confirm the presence and significance of zinc in conjunction with silver to ensure correct classification. The intent is to capture those silver-bearing materials where zinc plays a material role in their characterization.
