2620.19.60.40 - Silver content

This category, HTS 2620.19.60.40, specifically classifies slag, ash, and residues, other than those originating from the manufacture of iron or steel, which contain metals or their compounds, and are not primarily derived from zinc. The defining characteristic of goods within this subdivision is the presence of **silver content**. These materials are typically by-products of various industrial processes, such as smelting or refining, where silver is a significant component or impurity.

Distinguishing this category from its siblings is crucial for accurate classification. While all fall under "Other" slag, ash and residues not containing mainly zinc, this specific code isolates those where the primary metal of interest, after ruling out copper, lead, zinc, and gold, is silver. For example, while 2620.19.60.10 covers copper content and 2620.19.60.50 covers gold content, this code specifically applies when silver is the predominant valuable metal being recovered or identified within the residue.

As this is a leaf node, there are no further subdivisions under this HTS code. Therefore, the classification hinges entirely on the identification of silver as a significant constituent within the slag, ash, or residue, and the absence of predominantly higher-value or specifically designated metals like copper, lead, zinc, or gold. The classification relies on analytical testing to confirm the presence and relative proportion of silver, ensuring proper duty assessment and trade compliance.
