Import Tips
• Ensure the berberine sulfate is clearly identified as a salt of a natural alkaloid and provide a certificate of analysis to support classification
• Verify that the product is not put up as a medicament in measured doses, which would shift classification to Chapter 30
• Consult the CBSA's Advance Rulings service for binding classification decisions
