HS Code for Methyprylon

Methyprylon is classified under HS code 2933.72. This code is part of Chapter 29, which covers organic chemicals, and heading 2933, which is dedicated to heterocyclic compounds with nitrogen hetero-atom(s) only. Specifically, Methyprylon falls under the sub-category of lactams. A lactam is a cyclic amide, and Methyprylon (a piperidinedione derivative) fits this structural definition. Methyprylon is a sedative-hypnotic medication, and its classification is specifically named in the Harmonized System nomenclature alongside Clobazam under sub-heading 2933.72. This specific naming ensures that the substance is tracked accurately for both trade and regulatory purposes, given its nature as a pharmaceutical agent.

Common Misclassification

The most frequent misclassification for Methyprylon is HS code 3004.90. This occurs when the product is imported in the form of finished dosage units (like tablets or capsules) for retail sale. If it is in dosage form, Chapter 30 (Medicaments) takes precedence. However, as a bulk raw chemical, it must be classified in 2933.72. It is also sometimes confused with 2933.71 (6-Hexanelactam/Caprolactam), but 2933.72 is the specific international designation for Methyprylon. Importers must also distinguish it from other heterocyclic compounds in 2933.99.
