Aspirin Tromethamine Salt from Germany
Aspirin Tromethamine Salt is the tromethamine (tris) salt of O-acetylsalicylic acid, used for parenteral nutrition compatibility in clinical settings. Under Chapter 29 Note 5(C)(2), salts of organic bases with organic acids are classified with the acid or base occurring last in numerical order; tromethamine (an amino alcohol, heading 29.22) precedes O-acetylsalicylic acid (heading 29.18), so the salt is classified under 2918.22.00. It is a high-purity API, not a finished formulation.

Import Tips
• Confirm the salt is not put up in measured doses, as that would shift classification to Chapter 30
• Provide the CBSA with the CAS number and purity certificate to support classification under 2918.22.00
• If the product is for parenteral use, ensure compliance with Health Canada's Good Manufacturing Practices
