Import Tips
• Maintain documentation proving the product is a separate chemically defined compound, as pharmaceutical grade does not change classification
• Ensure the product is not put up in measured doses or for retail sale, which would shift classification to another heading
• Check if a Drug Establishment Licence is needed if the product is imported for pharmaceutical use
