HS Code for Antipyrine

Antipyrine, also known as phenazone, is classified under HS code 2933.11. This classification is found in Chapter 29, which covers organic chemicals. Specifically, 2933 covers heterocyclic compounds with nitrogen hetero-atom(s) only. Subheading 2933.11 is explicitly defined for "Phenazone (antipyrin) and its derivatives." The classification is based on the chemical structure of the molecule, which contains an unfused pyrazole ring. As a pure chemical substance, it must be classified in Chapter 29 rather than Chapter 30, provided it is not put up in measured doses or in forms or packings for retail sale as a medicament. The precision of this code allows for the monitoring of pharmaceutical precursors and active ingredients in international trade.

Products Included

• Antipyrine (Phenazone) in bulk
• Aminopyrine (Dimethylamino-phenazone)
• Propyphenazone
• Other derivatives of phenazone
• Pure chemical crystals of antipyrine

Common Misclassification

The most common misclassification is HS code 3004.90, which covers medicaments for retail sale. If antipyrine is sold as a finished medicine (e.g., ear drops or tablets), it moves to Chapter 30. Another error is using 2933.19, which is the "other" category for pyrazole rings; however, since antipyrine is specifically named in 2933.11, the specific code must be used per GRI 1.
