2620.99 - Other:

HTS code 2620.99 encompasses slag, ash, and residues, other than those specifically from the manufacture of iron or steel, which contain arsenic, metals, or their compounds, but do not fall into the more specific subcategories of this heading. This category serves as a residual grouping for such materials that do not meet the criteria for other, more precisely defined classifications within heading 2620.

This classification is distinguished from its sibling, 2620.91.00.00, by the absence of specific antimony, beryllium, cadmium, or chromium content, or mixtures thereof. While 2620.91.00.00 focuses on residues containing these particular metals, 2620.99.00.00 captures a broader range of other metallic-containing wastes and residues.

The subcategories within 2620.99 provide further refinement based on the primary metallic content or specific processing characteristics. These include materials predominantly containing vanadium or tungsten, residues with a significant nickel content (over 10% by weight), certain titanium-rich slags, and other residues not advanced in value or condition. The final subcategory, 2620.99.85.00, serves as the ultimate residual classification for all other materials fitting the general description of this heading but not covered by the preceding subcategories.
