HS code for Antipyrine: 2933.11

Heterocyclic compounds, with nitrogen hetero-atom(s) only, containing an unfused pyrazole ring (whether or not hydrogenated) in the structure, phenazone (antipyrin) and its derivatives.

Classification of antipyrine under HS 2933.11

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.

Codes often confused with 2933.11

Common mistake. 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.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
