Stannic Oxide (SnO2) Powder
Stannic oxide (SnO2) powder is a white, chemically defined inorganic compound of tin used as an opacifier in ceramics and to enhance glass durability. It is a separate chemically defined compound of Chapter 28, and its classification under tariff item 2825.90.00 reflects its status as an 'other' metal oxide. The powder form is standard for industrial use.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is prepared as an opacifier for ceramics
Prepared opacifiers of Chapter 32 take precedence over pure oxides.
If the powder is mixed with other oxides for glass production
Mixtures not chemically defined fall under Chapter 38.

Import Tips & Compliance
• Provide a certificate of analysis confirming the SnO2 content and absence of impurities that could affect classification
• If the powder is surface-treated or coated, it may fall outside Chapter 28
• Ensure proper labelling for transport as a chemical substance

Antimony-Doped Tin Oxide (ATO) Powder
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.
Beryllia Ceramic Powder
Beryllia ceramic powder is a high-purity form of beryllium oxide (BeO) used in aerospace and electronics for its thermal and insulating properties. It is a chemically defined inorganic compound, not a finished ceramic article, and is therefore classified under this tariff item for other inorganic bases and metal oxides.
