Choline Aspirin Salt
Choline Aspirin Salt is the choline salt of O-acetylsalicylic acid, a bioavailable form used in oral liquid analgesics. 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; choline (a quaternary ammonium base, heading 29.23) precedes O-acetylsalicylic acid (heading 29.18), so the salt is classified under 2918.22.00. It is a bulk chemical for pharmaceutical compounding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the choline component is considered the principal fragment
If the CBSA classifies by the quaternary ammonium base, heading 29.23 (choline) would apply.
If imported as a finished oral liquid analgesic
Medicaments in measured doses or retail sale are classified in Chapter 30 per Section VI Note 2.

Import Tips & Compliance
• Verify the product is not in retail packaging or measured doses, which would trigger Chapter 30 classification
• Provide the CBSA with the chemical name and salt stoichiometry to support classification under 2918.22.00
• If the product is for oral liquid formulations, ensure it meets Food and Drug Regulations under the Food and Drugs Act

ACS Reagent O-Acetylsalicylic Acid
ACS reagent-grade pure o-acetylsalicylic acid for laboratory analytical standards. This separate, chemically defined organic compound with a carboxylic acid and phenol function is specifically named in tariff item 2918.22.00.
Aluminum Aspirin Glycinate
Aluminum Aspirin Glycinate is a coordination compound formed between aluminum, O-acetylsalicylic acid (aspirin) and glycine, used as an active ingredient in sustained-release tablet formulations. Under Section VI Note 1(B) and Chapter 29 Note 5(C)(3), coordination compounds are classified with the organic fragment that occurs last in numerical order, which here is O-acetylsalicylic acid (heading 29.18). It is therefore classified under tariff item 2918.22.00 as a salt of O-acetylsalicylic acid.
Aspirin Diethylamine Salt
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.
Aspirin Lysine Salt
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.
Aspirin Meglumine Salt
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.
Aspirin Sodium Salt
The sodium salt of O-acetylsalicylic acid, commonly used in pharmaceutical formulations for improved water solubility in effervescent tablets and injections. Under Chapter 29 note 5(C)(1), inorganic salts of organic compounds are classified with the organic compound, so this falls under tariff item 2918.22.00.
