Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered other morphinan alkaloid without exact INN match
Chapter notes require latest numerical heading; unspecified morphinan derivatives fall under broader 2939 provisions.
If diluted or mixed for medicinal retail packs under 2g per package
Medicaments not in dosage form but put up for retail exclude bulk Chapter 29 chemicals.
If imported as chemical mixture with excipients for pharma processing
Prepared binders or chemical preparations for lab/pharma use shift from pure compounds (Chapter 29).

Levorphanol Tartrate
Levorphanol tartrate is the tartrate salt form of levorphanol, a potent opioid agonist chemically classified as a morphinan derivative with an isoquinoline ring system. It falls under HTS 2933.41.00.00 as a specific salt of levorphanol (INN), meeting Chapter 29 requirements for separate chemically defined organic compounds with nitrogen hetero-atoms. This pharmaceutical intermediate or active ingredient is used in pain management formulations.
Levorphanol Sulfate
Levorphanol sulfate represents the sulfate salt variant of levorphanol (INN), a heterocyclic opioid with nitrogen-containing isoquinoline structure. HTS 2933.41.00.00 applies directly as specified salts of this INN compound, per Chapter 29 scope for chemically defined organic compounds. Primarily imported as high-purity intermediate for analgesic formulations.
Pharmaceutical Grade Levorphanol Base
Pure levorphanol (base form, INN) is the parent morphinan opioid with quinoline ring system, imported at >99% purity for salt formation. Falls under HTS 2933.41.00.00 covering both the INN compound and its salts as chemically defined heterocyclics. Used exclusively as active pharmaceutical ingredient precursor.
Levorphanol (S)-Tartrate Dihydrate
The dihydrate form of (S)-levorphanol tartrate maintains the core isoquinoline opioid structure with added water crystallization. HTS 2933.41.00.00 classification holds as salt of specified INN, with hydration not affecting Chapter 29 organic compound status. Bulk import for sterile injectable opioid production.
