2939.80.00Quinine Sulfate Dihydrate
Quinine sulfate dihydrate is the sulfate salt of the quinine alkaloid, obtained from cinchona bark or produced synthetically, and used in the treatment of malaria and as a flavoring in tonic water. As a salt of an alkaloid, it is classified under tariff item 2939.80.00 as an 'other' alkaloid derivative.
2939.80.00Quinine Sulfate Dihydrate USP
Quinine sulfate dihydrate is a salt of the cinchona alkaloid, used in antimalarial drugs and tonic water. As a chemically defined alkaloid salt, it is classified under tariff item 2939.80.00 for other alkaloids and their salts, per Chapter 29 rules for salts of organic compounds.
2939.80.00Saxitoxin Hydrochloride
Saxitoxin hydrochloride is the salt form of saxitoxin, a naturally occurring paralytic shellfish toxin classified as an alkaloid. As a chemically defined alkaloid salt, it falls under tariff item 2939.80.00 for other alkaloids and their salts, per Chapter 29 rules for salts of organic compounds.
2939.80.00Saxitoxin in Aqueous Solution
Saxitoxin in aqueous solution is a chemically defined alkaloid dissolved in water for stability during transport. Per Chapter 29 note 1(d), solutions of alkaloids in water are classified under the same heading as the alkaloid, thus falling under tariff item 2939.80.00.
2939.80.00Saxitoxin Reference Standard
Saxitoxin reference standard is high-purity saxitoxin for analytical calibration, classified as a chemically defined alkaloid. As a pure alkaloid, it falls under tariff item 2939.80.00 for other alkaloids, despite its reference use, as it is not excluded by Chapter 29 notes.
2939.80.00Saxitoxin Sodium Salt
Saxitoxin sodium salt is the sodium derivative of saxitoxin, classified as an alkaloid salt. Per Chapter 29 note 5(C)(1), inorganic salts of organic compounds are classified with the parent organic compound, thus falling under tariff item 2939.80.00 for other alkaloid salts.
