Import Tips
• Ensure the product's purity meets the specifications of your intended use, as CBSA may require a certificate of analysis to confirm it is a chemically defined compound
• If the acid is imported as a salt, verify the classification, as salts are classified with the parent compound under Chapter 29 note 5
• Keep detailed records of the chemical structure to support the tariff classification in case of a CBSA review
