Products classified under HTS 2939.69.00.00
Ergotamine Tartrate
Ergotamine tartrate is a semi-synthetic derivative of ergot alkaloids from rye ergot (Claviceps purpurea), used primarily for treating migraines. It falls under HTS 2939.69.00.00 as a derivative of rye ergot alkaloids, specifically the tartrate salt form. This classification covers natural or synthetic alkaloids and their salts from rye ergot, excluding lysergic acid derivatives.
Ergocornine Base
Pure ergocornine is a rye ergot alkaloid isolated for pharmaceutical synthesis and neuropharmacology studies. HTS 2939.69.00.00 covers this natural alkaloid as 'other' rye ergot products, excluding salts/esters which remain in same heading per notes. It's a separate chemically defined compound per chapter note (a).
Ergosine Hydrobromide
Ergosine hydrobromide is a lesser-known rye ergot alkaloid salt used in biochemical studies. HTS 2939.69.00.00 applies as the hydrobromide salt of a rye ergot alkaloid per classification notes on salts. Supplied as high-purity powder for research.
Ergoclavine
Ergoclavine is a clavine-type alkaloid from rye ergot fungi, studied for neuroactive properties. Falls under HTS 2939.69.00.00 as a natural rye ergot alkaloid, per chapter scope for separate chemically defined compounds. Often synthesized for purity.
Isoergosine
Isoergosine is an isomer of ergosine from rye ergot, used in stereochemistry studies. HTS 2939.69.00.00 covers this as a rye ergot derivative; chapter note (b) includes isomers of organic compounds. Chemically defined and separate from mixtures.
Ergostine
Ergostine represents ergoline alkaloids from rye ergot used in synthetic chemistry. Classified HTS 2939.69.00.00 as other rye ergot alkaloids, meeting purity standards of chapter notes. Base form without salts or esters.
Dihydroergotamine Mesylate
Dihydroergotamine mesylate is a hydrogenated derivative of ergotamine from rye ergot, administered via injection for acute migraine treatment. Classified under HTS 2939.69.00.00 as 'other' derivatives of rye ergot alkaloids and their salts. The mesylate salt form qualifies under chapter provisions for salts of organic compounds.
Ergocristine Phosphate
Ergocristine phosphate is a natural alkaloid extracted from rye ergot sclerotia, used in research and as a dopamine receptor agonist precursor. It qualifies for HTS 2939.69.00.00 as a rye ergot alkaloid salt, per chapter note (a) for chemically defined organic compounds. Excludes mixtures or preparations beyond simple salts.
Ergometrine Maleate
Ergometrine maleate (ergonovine maleate) is an ergot alkaloid derivative used to control postpartum hemorrhage. It falls under HTS 2939.69.00.00 as a salt of rye ergot alkaloids, consistent with chapter note (C)(1) for organic compound salts. Primarily imported for bulk pharmaceutical use.
Ergocristinine
Ergocristinine is an isolysergic acid derivative from rye ergot, used in alkaloid research. Classified in HTS 2939.69.00.00 as 'other' rye ergot derivatives, distinguished from lysergic acid amide (2939.41). Meets chapter note for chemically pure organic compounds.
