Import Tips
• Ensure the product is in primary form (powder or granules) and not mixed with excipients, as compounded preparations may shift classification
• Obtain a Health Canada establishment licence if the CMC will be used in drug products
• Keep technical data sheets showing the degree of substitution and cross-linking to support the tariff classification
