Antimony-Doped Tin Oxide (ATO) Powder from Germany
Antimony-doped tin oxide (ATO) is a powder consisting of tin dioxide doped with antimony to impart electrical conductivity. While it is a metal oxide, the doping introduces an additional element, making it a mixture rather than a single chemically defined compound. However, it is classified under tariff item 2825.90.00 as an 'other' inorganic base or metal oxide, consistent with its oxide character.

Import Tips
• Be prepared to demonstrate that the antimony doping does not render the product a separate chemically defined compound
• Provide technical data sheets showing the oxide basis of the product
• If the ATO is dispersed in a polymer or solvent, classification may shift to Chapter 38 or 39
