Import Tips
• Ensure your commercial invoice clearly states the product's end use in Canadian manufacturing to support the preferential tariff claim
• The CBSA may request a Certificate of Analysis to confirm the product's identity as DDBSA
• If the acid is neutralized to a salt before import, it may be classified differently, so verify the exact form at the time of importation
