High-Purity Tungsten Oxide Sputtering Target
High-purity tungsten oxide sputtering targets (99.99% WO3) are solid forms of tungsten trioxide used for physical vapor deposition in semiconductor manufacturing. As a chemically defined metal oxide, it is classified under Chapter 28. Tariff item 2825.90.00 covers this product as an 'other' metal oxide, and the sputtering target form does not alter its chemical classification.

Import Tips & Compliance
• Ensure the target is not mounted on a backing plate, which could reclassify it as machinery parts
• Provide the CBSA with the purity certificate and dimensions
• If the target is for semiconductor equipment, consider whether Chapter 84 or 85 applies to the complete machine

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.
Beryllium Hydroxide Flakes
Beryllium hydroxide flakes are a chemically defined metal hydroxide produced from beryl ore. They are used as a precursor in nuclear and ceramic applications and are classified here as an inorganic base.
Beryllium Oxide Powder
High-purity beryllium oxide powder is a chemically defined compound used in ceramics and electronics. It is not a finished product and falls under this tariff item for other metal oxides.
