Import Tips
• Ensure the product is labeled as a reference standard for laboratory use only, as this may affect classification and regulatory requirements
• Provide a certificate of analysis and pharmacopeial documentation to the CBSA to support the tariff classification
• Verify whether a Controlled Drugs and Substances Act permit is needed, as growth hormone derivatives may be regulated in Canada
