Ethinamate USP Powder
Pharmaceutical-grade ethinamate powder meeting United States Pharmacopeia standards, a cyclic carbamate used historically as a sedative-hypnotic. Classified under HTS 2924.24.00.00 as it is the specific chemically defined compound ethinamate (INN), a derivative of cyclic amides of carbonic acid. Supplied as pure active pharmaceutical ingredient for research or formulation.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a formulated pharmaceutical preparation
Finished dosage forms like tablets containing ethinamate would classify under heterocyclic compounds with nitrogen hetero-atom(s) only when in medicaments.
If put up in dosage form for retail therapeutic use
Medicaments consisting of cyclic amides like ethinamate in measured doses fall under Chapter 30 for pharmaceuticals.
If dissolved in solvents exceeding safety/transport limits
Solutions not qualifying under Chapter 29 note (e) classify as diagnostic or laboratory reagents if for specific analytical use.

Import Tips & Compliance
• Obtain DEA registration if importing for any controlled substance-related research, as ethinamate has sedative properties
• Provide Certificate of Analysis (CoA) confirming 99%+ purity and INN identity to avoid reclassification as mixtures
• Declare as 'pure chemical reference standard' to prevent scrutiny under pharmaceutical finished dosage forms
