HS Code for Phentermine

Phentermine is classified under HS code 2921.46. This classification is found within Chapter 29, which covers organic chemicals. Specifically, heading 2921 is for amine-function compounds. Within this heading, the sub-category 2921.40 covers aromatic monoamines and their derivatives. Subheading 2921.46 is a specific international designation for several controlled substances and their salts, including amfetamine, benzfetamine, dexamfetamine, and phentermine. Phentermine is a sympathomimetic amine used as an appetite suppressant. The classification is based on the chemical structure of the molecule—an aromatic ring attached to an amine group. Because it is a pure chemical compound (or a salt thereof), it is classified in Chapter 29 rather than Chapter 30, provided it is not yet put up in measured doses or in forms or packings for retail sale. The inclusion of phentermine in 2921.46 is part of a global effort to monitor and control the trade of psychotropic substances. Customs authorities use this specific code to track the movement of these chemicals to ensure compliance with international drug control treaties and national regulations.

Common Misclassification

Phentermine is frequently misclassified under 3004.90 if it is already in tablet or capsule form for retail sale. Chapter 29 is only for bulk chemicals. Another error is using 2921.49, which is the residual category for \"other\" aromatic monoamines. Since phentermine is explicitly named in the 2921.46 subheading, using the residual code is a violation of the General Rules of Interpretation (GRI).
