4-Anilino-N-phenethylpiperidine (ANPP) Pure Compound
4-Anilino-N-phenethylpiperidine (ANPP) is a synthetic organic compound with an unfused piperidine ring (a hydrogenated pyridine ring) containing a nitrogen hetero-atom. It is specifically named in tariff item 2933.36.00 and is classified here because it falls under the heading for heterocyclic compounds with nitrogen hetero-atom(s) only.
ANPP Dissolved in Safety Solvent
ANPP dissolved in a solvent is classifiable under tariff item 2933.36.00 when the solvent is added solely for safety or transport reasons and does not make the product suitable for a specific use. This aligns with Chapter 29 Note 1(e), which allows such solutions to retain their classification as the pure compound.
