Cassiterite Concentrate (Natural SnO2)
Cassiterite concentrate is a natural mineral consisting primarily of tin dioxide (SnO2), typically above 70% purity. Although it is a mineral of natural origin, it is classified under Chapter 28 as a chemically defined tin oxide when it meets the purity criteria. Tariff item 2825.90.00 covers this product as an 'other' metal oxide.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cassiterite is in its natural state and not sufficiently purified
Tin ores and concentrates are classified in Chapter 26.
If the product is a mixed ore containing other metals
Other ores and concentrates fall under Chapter 26.

Import Tips & Compliance
• Verify that the concentrate exceeds the purity threshold to qualify as a chemically defined compound; lower-grade ores may fall under Chapter 26
• Provide assay results to the CBSA to support classification
• Note that environmental and mining regulations may apply to natural mineral imports

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.
