2939.61.00.00 - Ergometrine and its salts

This HTS classification, 2939.61.00.00, specifically covers ergometrine and its various salt forms. Ergometrine, also known as ergonovine, is an alkaloid derived from the ergot fungus. It is primarily recognized for its pharmaceutical applications, particularly in obstetrics for controlling postpartum hemorrhage due to its potent oxytocic properties, causing uterine contractions. Its classification at this level is within the broader category of alkaloids, natural or synthesized, and their derivatives.

To distinguish this category from its siblings, it is important to note that while all fall under the umbrella of ergot alkaloids, 2939.61.00.00 is exclusively for ergometrine and its salts. Category 2939.62.00.00 pertains to ergotamine and its salts, a distinct ergot alkaloid with different chemical structures and primary uses, often in migraine treatment. Similarly, 2939.63.00.00 is reserved for lysergic acid and its salts, which are precursors or breakdown products rather than the active pharmacological agents themselves. The "Other" category (2939.69.00.00) serves as a residual classification for any ergot alkaloid derivatives not specifically listed.

As this is a leaf node in the HTS structure, there are no further subcategories under 2939.61.00.00. Therefore, the classification concludes at this point, encompassing all forms and salts of ergometrine. Classification under this code relies on the specific identification of the substance as ergometrine or a salt thereof, based on chemical analysis, product documentation, or established pharmaceutical nomenclature.
