Overview

This HTS classification, 2933.99.51.00, specifically covers Hydralazine hydrochloride. Hydralazine hydrochloride is an organic chemical compound belonging to the group of heterocyclic compounds with nitrogen heteroatoms, further categorized under "Other" aromatic or modified aromatic compounds, and ultimately designated as a drug. Its primary use is as a pharmaceutical ingredient, specifically for treating cardiovascular conditions.

This category distinguishes itself from its sibling category, 2933.99.53.00 ("Other"), by its specific chemical identity and intended pharmaceutical application. While the sibling category encompasses a broader range of "other" compounds within the "Drugs" and "Cardiovascular drugs" subheadings, 2933.99.51.00 is exclusively reserved for Hydralazine hydrochloride.

As this is a leaf node in the HTS classification structure, there are no further subcategories to introduce. Classification under this code relies on the precise identification of the imported or exported substance as Hydralazine hydrochloride, meeting the established chemical and pharmaceutical specifications for this particular drug.
