Import Tips
• Verify the product is in unworked form (powder, crystals, or rods) and not doped; doped or wafer-cut forms fall under different headings
• Provide purity certificates (6N) to support the classification
• Be aware that semiconductor applications may attract additional scrutiny from the CBSA regarding end-use
