2937.90.10.00 - Epinephrine hydrochloride

This HTS classification covers epinephrine hydrochloride, a synthetic derivative of the natural hormone epinephrine. Epinephrine hydrochloride is specifically identified as a catecholamine hormone. Its primary use is as a medication, acting as a potent vasoconstrictor and bronchodilator. The classification is precise, denoting this specific chemical compound within the broader category of hormones and their synthetic analogues.

Category 2937.90.10.00 is distinguished from its sibling category, 2937.90.20.00 ("Other"), by its specific identification of epinephrine hydrochloride. While the "Other" category would encompass any other catecholamine hormones, their derivatives, or structural analogues not otherwise specified, this code is exclusively for epinephrine hydrochloride. This precise enumeration allows for accurate tariff application and statistical tracking of this particular pharmaceutical substance.

As this classification represents a leaf node, there are no further subcategories. The specific nature of epinephrine hydrochloride means it is not further subdivided under this HTS heading. Classification at this level requires confirmation of the chemical identity and its role as a catecholamine hormone derivative.
