About HS Code 293336

This HS code identifies 4-anilino-N-phenethylpiperidine (ANPP), a critical precursor chemical in the illicit synthesis of fentanyl and its analogues. Its trade is extremely restricted and heavily monitored globally due to its direct link to the production of highly dangerous controlled substances. Legitimate international trade is virtually non-existent, limited to highly specialized research laboratories or government agencies for forensic analysis or counter-narcotics efforts, and only under strict licensing and oversight. Importers and exporters are typically government-authorized entities or highly regulated chemical suppliers with specific permits. Key things to know include its classification as a Schedule I or II precursor chemical under various national and international drug control laws, making unauthorized possession, trade, or manufacture illegal and subject to severe penalties. Its presence in trade often signals illicit activity.

Products Under This Code

4-ANPP, N-phenethyl-4-anilinopiperidine, Fentanyl precursor ANPP, 4-Anilino-N-phenethylpiperidine hydrochloride

Real World Examples

Cayman Chemical ANPP (forensic standard), Cerilliant ANPP (analytical reference material)

Common Misclassification

ANPP is often confused with other fentanyl precursors like NPP (HS 2933.37) or other piperidine derivatives, necessitating precise chemical identification to avoid misclassification and ensure proper regulatory enforcement.

Products Classified Under 2933.36

Industry

This code belongs to the Chemicals industry.

Trade Overview

Due to its illicit use, trade is primarily monitored in countries with significant illicit drug production or transit, such as Mexico, China, and the USA.
