2620.99.85.00 - Other

HTS code 2620.99.85.00 encompasses a broad category of miscellaneous residues and ashes, specifically those not already classified under more specific subheadings within 2620.99. This classification applies to materials derived from industrial processes that contain arsenic or metals, or their compounds, but do not fit the defining characteristics of sibling categories such as those rich in vanadium, tungsten, nickel, or titanium, nor are they specifically defined as materials not advanced in value or condition with particular copper, lead, or zinc content criteria.

The primary distinguishing factor for 2620.99.85.00 lies in its residual nature and its "catch-all" function within the heading. Unlike siblings that specify dominant metal content or particular processing states, this category is for all other slags, ashes, and residues falling under Chapter 26 that meet the general criteria of the heading but lack the specific attributes to be classified elsewhere. For instance, while sibling 2620.99.75 addresses certain residues not advanced in value and with specific copper, lead, or zinc limits, 2620.99.85.00 would capture materials that may have undergone some minor advancement in condition or value, or contain other metals not specifically itemized in the other subheadings.

As a leaf node, 2620.99.85.00 does not have further subdivisions. Therefore, classification within this code relies heavily on a process of elimination, ensuring that the material in question meets the general requirements of heading 2620 (slag, ash, and residues containing arsenic, metals or their compounds, other than from the manufacture of iron or steel) and cannot be classified under any of the more specific sibling subheadings based on its composition, origin, or physical state. Practical classification often involves laboratory analysis to determine the precise elemental composition and to confirm the absence of the specific characteristics that would place it in a more defined sibling category.
