Products classified under HTS 2939.20.00.10
Quinine Sulfate Dihydrate
Quinine sulfate dihydrate is the dihydrate salt form of quinine, a natural alkaloid extracted from cinchona bark, used primarily as an antimalarial medication. This product falls under HTS 2939.20.00.10 as a salt of quinine, fitting Chapter 29's scope for chemically defined organic compounds and their salts. It is typically supplied as a white, crystalline powder for pharmaceutical formulations.
Quinine Hydrochloride
Quinine hydrochloride is a water-soluble salt of quinine alkaloid, widely used in injectable antimalarial treatments and tonic water production. Classified under HTS 2939.20.00.10 as a quinine salt per Chapter 29 notes for separate chemically defined organic compounds. It appears as a colorless to white crystalline powder.
Quinine Dihydrochloride
Quinine dihydrochloride is the dihydrochloride salt of quinine, preferred for intravenous administration in severe malaria cases due to high solubility. This fits HTS 2939.20.00.10 as a chemically defined quinine salt under Chapter 29's alkaloid provisions. Supplied as a sterile powder for reconstitution.
Quinine Gluconate
Quinine gluconate is a gluconate salt of quinine used in oral antimalarial therapies with good gastrointestinal tolerance. It qualifies under HTS 2939.20.00.10 per Chapter 29 note (C)(1) classifying organic salts with their parent alkaloid. Commonly available as powder for compounding.
Quinine Sulfate USP Grade
Pharmaceutical grade quinine sulfate meeting USP monograph standards for use in bulk drug manufacturing. This pure quinine salt is specifically covered by HTS 2939.20.00.10 as a natural alkaloid salt under Chapter 29 provisions for chemically defined compounds.
Quinine Hydrochloride Dihydrate
The dihydrate form of quinine hydrochloride, providing two water molecules per salt unit for enhanced stability in humid conditions. Classified as HTS 2939.20.00.10 following Chapter 29 rules for alkaloid salts, whether hydrated or anhydrous.
Quinine Base (from Salts)
Quinine alkaloid liberated from its salts, appearing as a white amorphous powder with characteristic bitter taste. While the base itself may have different classification, bulk quinine derived from approved salts maintains HTS 2939.20.00.10 status under alkaloid provisions.
Quinine Sulfate for Tonic Water
Technical grade quinine sulfate specifically purified for beverage industry use in tonic water production, meeting food chemical codex standards. Still classified under HTS 2939.20.00.10 as the pure alkaloid salt per Chapter 29, not as a food additive.
