Aspirin Lysine Salt from Mexico
Aspirin Lysine Salt is the lysine salt of O-acetylsalicylic acid, used in rapid-absorption intravenous formulations for 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; lysine (heading 29.22) precedes O-acetylsalicylic acid (heading 29.18), so the salt is classified under 2918.22.00. It is a bulk pharmaceutical ingredient, not put up for retail sale.
