Aspirin Diethylamine Salt from Japan
Aspirin Diethylamine Salt is an organic salt formed between O-acetylsalicylic acid and diethylamine, used as a bulk chemical for topical analgesic gels. Under Chapter 29 Note 5(C)(2), salts formed between organic compounds are classified in the heading appropriate to the acid or base that occurs last in numerical order; O-acetylsalicylic acid (heading 29.18) occurs after diethylamine (heading 29.21), so the salt falls under 2918.22.00.

Import Tips
• Confirm the salt is not put up in measured doses or for retail sale, as that would shift classification to Chapter 30
• Provide the chemical name and CAS number to the CBSA to support classification under 2918.22.00
• If the product is for pharmaceutical use, ensure it meets Health Canada's import requirements
