Beryllia Ceramic Powder
Beryllia ceramic powder is beryllium oxide (BeO) in powder form, a separate chemically defined compound of beryllium. It is classified under tariff item 2825.90.00 as an 'other' inorganic base oxide, not yet formed into finished ceramic articles. The powder is used as a raw material for high-temperature ceramic substrates in aerospace applications.

Import Tips & Compliance
• Ensure the powder is not mixed with binders or organic additives that could shift classification to a preparation of Chapter 38
• Provide a certificate of analysis confirming the chemical identity and purity of the beryllium oxide
• Check if the powder requires an import permit under Canada's Nuclear Safety and Control Act due to beryllium content
