2620.29.00.50 - Gold content

This classification, HTS Code 2620.29.00.50, specifically addresses slag, ash, and residues, other than those generated from the manufacture of iron or steel, which contain arsenic, metals, or their compounds, and are not primarily classified under lead-containing residues. Within the broader category of "Slag, ash and residues (other than from the manufacture of iron or steel), containing arsenic, metals or their compounds: Containing mainly lead: Other," this particular subheading focuses on those residues where gold is the predominant or significant metallic component, or where gold is the specific metallic element being identified for classification purposes and is not covered by the other listed metallic contents.

This subheading distinguishes itself from its sibling categories by its specific focus on gold content. While 2620.29.00.10 covers copper content, 2620.29.00.20 addresses lead content, 2620.29.00.30 pertains to zinc content, and 2620.29.00.40 is for silver content, this code is exclusively for residues where the classifying metallic element is gold. This ensures that residues are precisely categorized based on their primary metallic composition, preventing misclassification and ensuring accurate duty assessment.

As a leaf node, there are no further subcategories under 2620.29.00.50. Therefore, classification under this code relies directly on the determination that the residue falls under the general heading of slag, ash, and residues containing arsenic, metals, or their compounds, is not primarily lead-containing, and specifically contains gold as the basis for its classification, or where the gold content is the primary element of concern for customs purposes, distinct from the other named metallic elements in its sibling categories.
