2616.90.00.10 - Copper content

This HTS category, 2616.90.00.10, specifically covers ores and concentrates where copper is the predominant precious metal, or where copper is present alongside other precious metals but is the primary focus for classification due to its economic significance or quantity. It falls under the broader heading of precious metal ores and concentrates, excluding those primarily classified by their lead, zinc, gold, or other precious metal content.

When classifying goods under heading 26.16, it is crucial to determine the principal precious metal present. This subcategory is distinct from siblings such as 2616.90.00.20 (Lead content), 2616.90.00.30 (Zinc content), 2616.90.00.40 (Gold content), and 2616.90.00.50 (Other precious metal content) based on the dominant or determinative precious metal identified in the ore or concentrate. For instance, an ore with significant gold and copper content would be classified under 2616.90.00.40 if gold is the primary precious metal, whereas this category applies if copper is the primary precious metal.

As this is a leaf node, there are no further subdivisions. Therefore, the classification hinges on the accurate identification and quantification of copper as the principal precious metal within the context of the ore or concentrate. This requires careful analysis of assay reports and any available documentation detailing the mineral composition and its economic value.
