HS Code for Methaqualone

Methaqualone is classified under HS code 2933.55 because it is a heterocyclic compound containing a pyrimidine ring system. According to the General Rules for the Interpretation of the Harmonized System (GRI), organic chemicals are categorized based on their molecular structure. Methaqualone (INN) is specifically named in the subheadings of 2933, which covers heterocyclic compounds with nitrogen hetero-atom(s) only. The pyrimidine ring is a six-membered aromatic heterocycle with two nitrogen atoms at the 1 and 3 positions. Since methaqualone contains this specific structure and is a chemically defined organic compound, it must be classified within this specific subheading rather than more general categories. This classification remains consistent regardless of whether the product is in its base form or as a salt, such as methaqualone hydrochloride. The international trade of this substance is strictly monitored under the Convention on Psychotropic Substances, which is reflected in its specific identification within the Harmonized System to facilitate global tracking and regulatory compliance.

Products Included

Common Misclassification

Methaqualone is frequently confused with other heterocyclic compounds under HS code 2933.59, which serves as a residual category for other pyrimidine or piperazine derivatives. It may also be misclassified under HS code 3004 if it is prepared as a medicament in measured doses for therapeutic use. However, as a raw chemical substance, it must remain in Chapter 29. Another common error is placing it under 2933.54, which is reserved for other specific derivatives like malonylurea (barbituric acid).
