Aspirin Meglumine Salt from Mexico
Aspirin Meglumine Salt is a salt formed between O-acetylsalicylic acid and meglumine (N-methylglucamine), used for stabilizing contrast media formulations. As an organic salt, it is classified under Chapter 29 Note 5(C)(2) with the acid component that occurs last in numerical order; meglumine (a sugar amine, heading 29.40) precedes O-acetylsalicylic acid (heading 29.18), so the salt falls under 2918.22.00. The product is a bulk chemical, not a finished medicament.

Import Tips
• Ensure the meglumine salt is not classified as a sugar derivative under heading 29.40, as the salt rule in Note 5(C)(2) takes precedence
• Provide the CBSA with the exact chemical structure and salt stoichiometry
• If the product is for contrast media, verify it is not part of a finished diagnostic kit
