HS Code for Dinoseb

Dinoseb (ISO), a chemical compound known as 2-sec-butyl-4,6-dinitrophenol, is classified under HS code 2908.91. This classification is part of Chapter 29 (Organic Chemicals), specifically under the heading for phenol or phenol-alcohol derivatives that have been halogenated, sulphonated, nitrated, or nitrosated. Dinoseb is a nitrated derivative of phenol, which dictates its placement in this specific category. Because it is a highly regulated substance often used as a herbicide or insecticide, it is specifically named in the subheading 2908.91. The classification remains consistent whether the product is in its pure form or as a salt of the parent compound. This specific identification in the HS nomenclature helps customs authorities monitor the trade of hazardous substances regulated under international environmental agreements like the Rotterdam Convention.

Common Misclassification

Dinoseb is often misclassified under HS code 3808.93, which covers herbicides and plant-growth regulators. While Dinoseb is used as a herbicide, Chapter 29 takes precedence for chemically defined pure compounds unless they are prepared as retail formulations or mixtures. It may also be confused with 2908.11 (Pentachlorophenol), though the chemical structure of nitrated vs. halogenated phenols clearly separates them.
