HS Code for Hydroquinone

Hydroquinone, chemically known as benzene-1,4-diol or quinol, is classified under HS code 2907.22. This classification is governed by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically focusing on the chemical structure of the compound. Chapter 29 covers organic chemicals, and Heading 2907 is dedicated to phenols and phenol-alcohols. Hydroquinone is a dihydric phenol, meaning it contains two hydroxyl groups attached to a benzene ring in the para position. According to the Chapter 29 notes, chemically defined organic compounds are classified here even if they contain impurities, provided they are not in a mixture or prepared as a finished product for a specific retail use. The classification 2907.22 specifically identifies hydroquinone and its salts, ensuring that this specific polyphenol is distinguished from monophenols like phenol or naphthols. Its primary use as a reducing agent in photography or as a stabilizer in various industrial processes does not change its classification as a pure chemical compound under this heading.

Common Misclassification

Hydroquinone is frequently misclassified under HS code 2907.11, which is reserved for pure phenol (carbolic acid). While both are phenols, 2907.11 is for monophenols, whereas hydroquinone is a polyphenol. Another common error is classifying it under HS code 3824.99 as a miscellaneous chemical product; however, Chapter 29 takes precedence for separate chemically defined compounds. Furthermore, if hydroquinone is prepared as a skin-lightening cream, it must be classified under HS code 3304.99 (cosmetics) rather than 2907.22.

FAQ

What is the HS code for hydroquinone?

The HS code for hydroquinone (quinol) and its salts is 2907.22.

Is hydroquinone classified differently if used in photography?

If it is a separate chemically defined compound, it remains under 2907.22. However, if it is mixed with other substances and packaged for retail sale as a photographic developer, it may fall under HS code 3707.90.
