Overview
This HTS category, 2933.55.00.00, specifically enumerates certain pharmaceutical substances characterized by their heterocyclic structures containing nitrogen atoms and a pyrimidine ring. It encompasses loprazolam (INN), mecloqualone (INN), methaqualone (INN), and zipeprol (INN), along with their respective salts. These compounds are primarily recognized for their pharmacological activities and are thus subject to specific controls and classifications within the chemical sector.
Distinguishing this category from its siblings, it focuses on a precise list of named active pharmaceutical ingredients, rather than broader chemical families. Unlike 2933.52 and its subsequent subcategories, which deal with malonylurea (barbituric acid) and its derivatives, 2933.55.00.00 covers distinct chemical entities with different therapeutic applications. Similarly, it stands apart from the "Other" category (2933.59) by detailing specific recognized substances.
As this is a leaf node within the HTS classification, there are no further subdivisions. The classification relies on the precise identification of the named substances: loprazolam, mecloqualone, methaqualone, and zipeprol, and their salts. When classifying goods under this code, verification of the chemical identity of the substance and its salt form, if applicable, is paramount. This ensures accurate import and export processing for these specific pharmaceutical compounds.
