2939.62.00.00 - Ergotamine and its salts

This HTS classification, 2939.62.00.00, specifically covers ergotamine and its salts. Ergotamine is an alkaloid derived from the ergot fungus, which grows on rye and other grains. It is primarily known for its medicinal properties, particularly in the treatment of migraine headaches. The classification extends to include any salts formed from ergotamine, which are often used to improve its solubility and bioavailability for pharmaceutical preparations.

This category is distinct from its sibling, 2939.61.00.00 (Ergometrine and its salts), which covers a different alkaloid from ergot. While both are derived from ergot fungus, ergometrine has a different chemical structure and is typically used to prevent or control postpartum bleeding due to its action on uterine muscles. Furthermore, it differs from 2939.63.00.00 (Lysergic acid and its salts), which classifies lysergic acid itself, a precursor and breakdown product of various ergot alkaloids, rather than the specific alkaloids ergotamine or ergometrine. The "Other" category, 2939.69.00.00, serves as a residual classification for any other ergot alkaloid derivatives not specifically listed elsewhere.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, classification under 2939.62.00.00 relies directly on identifying the product as ergotamine or one of its salts. The key determinant for classification will be the chemical identity of the imported or exported substance, often confirmed through laboratory analysis or product documentation, ensuring it aligns precisely with the structure and properties of ergotamine.
