Import Tips & Compliance
• Provide a certificate of analysis showing the BeO purity and absence of dopants that could make it a product of Chapter 38
• Ensure the powder is not doped for electronics use in disc or wafer form, which would fall under heading 38.18
• Check if the product is subject to Canadian import controls on beryllium compounds
