Import Tips
• Ensure the powder is not packaged in measured doses or retail packs, as that would shift classification to heading 30.04
• Provide a certificate of analysis and a detailed product description to CBSA to confirm the alkaloid content and therapeutic use
• Verify whether a Drug Identification Number (DIN) or an exemption is required for bulk pharmaceutical ingredients
