About HS Code 293333

This HS code covers a highly specific group of potent pharmaceutical substances, primarily opioids (like alfentanil, carfentanil) and benzodiazepines (bromazepam), all characterized by an unfused pyridine or piperidine ring structure. Due to their classification as controlled substances and high potential for abuse, international trade in these compounds is extremely restricted and subject to stringent regulations by national and international drug control agencies. Importers and exporters are typically licensed pharmaceutical manufacturers, research institutions, and government agencies, dealing with these substances strictly for medical, scientific, or analytical purposes. Compliance with international treaties like the UN Single Convention on Narcotic Drugs and the Convention on Psychotropic Substances is paramount.

Products Under This Code

Alfentanil, Carfentanil, Bromazepam, Diphenoxylate, Anileridine, Bezitramide, Difenoxin, Dipipanone

Real World Examples

Sufenta (Alfentanil), Lexotan (Bromazepam), Lomotil (Diphenoxylate, in combination), specific research-grade controlled substances

Common Misclassification

These compounds are often confused with other controlled substances (e.g., under 2939 for alkaloids or 2934 for other heterocyclics) or other pharmaceutical preparations (3004), but their specific chemical structure and INN designation are critical for this classification.

Products Classified Under 2933.33

Industry

This code belongs to the Chemicals industry.

Trade Overview

Trade is highly regulated and occurs primarily between countries with advanced pharmaceutical industries and strict drug control frameworks, such as the USA, European Union members, and Canada.
