HS Code for Phenazone

Phenazone, also known as antipyrin, is classified under HS code 2933.11. This classification is determined by its chemical structure as a heterocyclic compound containing an unfused pyrazole ring. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2933 is dedicated to heterocyclic compounds with nitrogen hetero-atom(s) only. Subheading 2933.11 specifically names phenazone and its derivatives. As a pure chemical substance, it is classified here regardless of its intended use in the pharmaceutical industry, provided it has not been mixed with other ingredients or put up in measured doses for retail sale.

Products Included

Common Misclassification

Phenazone is frequently misclassified under HS code 2933.19, which is the residual category for "other" pyrazole derivatives. However, because phenazone is explicitly named in 2933.11, the more specific code must be used. It is also sometimes confused with HS code 3004.90 if the importer views it as a finished medicine; however, Chapter 29 is for separate chemically defined compounds, whereas Chapter 30 is for prepared medicaments.

FAQ

What is the HS code for Phenazone?

The specific HS code for phenazone (antipyrin) and its derivatives is 2933.11.

Is phenazone classified differently if it is a liquid?

No, the physical state (powder, crystal, or liquid solution) does not change the classification under 2933.11 as long as it remains a separate chemically defined compound.
