Import Tips & Compliance
• Maintain documentation proving pharmacopoeia compliance (BP/EP certificates) for CBSA and Health Canada review
• Ensure the product is in primary form and not formulated into a pharmaceutical preparation, which would be classified in Chapter 30
• Verify whether the sterile presentation affects classification, as sterilization alone does not remove it from Chapter 39
