HS Code for 4-anilino-N-phenethylpiperidine

4-anilino-N-phenethylpiperidine, frequently referred to by its acronym ANPP, is classified under HS code 2933.36. This classification is based on its chemical structure as a heterocyclic compound containing an unfused pyridine ring. Specifically, it is a derivative of piperidine. As an organic chemical, it resides within Chapter 29 of the Harmonized System. The specific subheading 2933.36 was established to monitor the trade of this substance due to its critical role as a primary precursor in the illicit and licit manufacture of fentanyl and its various analogues. The classification is determined by the General Rules of Interpretation (GRI), specifically Rule 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since ANPP is a defined organic compound, it must be classified according to its molecular architecture regardless of its intended use in pharmaceutical research or industrial synthesis.

Common Misclassification

ANPP is often misclassified under HS code 2933.33, which is reserved for fentanyl and its derivatives like alfentanil, sufentanil, and remifentanil. While ANPP is used to make these substances, it is a precursor and not the finished narcotic. It may also be confused with HS code 2933.39, which serves as a residual category for other heterocyclic compounds with an unfused pyridine ring not elsewhere specified. However, because 2933.36 specifically names ANPP, it takes precedence over the general 2933.39 code.
