Overview
This classification, HTS Code 2933.41.00.00, specifically covers Levorphanol (INN) and its salts. Levorphanol is a synthetic opioid analgesic belonging to the morphinan class, characterized by a chemical structure that includes a quinoline ring system, which is a key defining feature of the broader group under which it falls. Its primary use is medicinal, as a pain reliever.
Within the context of heterocyclic compounds with nitrogen hetero-atoms, this subcategory distinguishes itself by its precise identification of a specific compound and its salt forms, rather than a broader group of substances. The sibling category, 2933.49, covers "Other" compounds containing a quinoline or isoquinoline ring-system that are not further fused and are not Levorphanol or its salts. Therefore, the primary distinction lies in the specific identity of the chemical substance.
As this is a leaf node in the HTS, there are no further subcategories. The classification is specific to Levorphanol and its salts, meaning any chemical compound fitting this description, whether in its pure form or as a salt, will be classified under this code. Classification relies on confirming the chemical identity of the imported or exported substance to match the definition of Levorphanol and its salts.
