Overview

This HTS classification, 2620.21.00.30, specifically covers residues containing zinc, derived from the processing of leaded gasoline and leaded anti-knock compounds. These sludges are byproducts of industries that utilized lead-based additives in fuels, and are characterized by their significant zinc content.

This category is distinct from its siblings by its specific focus on zinc as the primary metal or compound within the sludge. While other categories within 2620.21.00 cover residues with copper (2620.21.00.10), lead (2620.21.00.20), silver (2620.21.00.40), or gold (2620.21.00.50) as their predominant component, this subcategory isolates those where zinc is the principal element or compound of value, necessitating a separate classification for accurate trade tracking and duty assessment. As a leaf node, there are no further subcategories; the classification ends with the specific identification of zinc-containing sludges from leaded gasoline and anti-knock compounds.
