HS code for DNOC: 2908.92
Phenol or phenol-alcohol derivatives, sulphonated, nitrated or nitrosated derivatives thereof, 4,6-dinitro-o-cresol (DNOC (ISO)) and its salts.
Classification of DNOC under HS 2908.92
DNOC, or 4,6-dinitro-o-cresol, and its salts are classified under HS code 290892. This substance is a nitrated derivative of a phenol, placing it within Chapter 29 (Organic Chemicals) and heading 2908. Heading 2908 specifically covers phenol or phenol-alcohol derivatives that are sulphonated, nitrated, or nitrosated. DNOC is a highly toxic compound used historically as a herbicide and insecticide. The classification 290892 is a specific subheading created to identify this substance due to its inclusion in the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals. This code applies to the chemical in its pure form or as a separate chemically defined compound, including its various salts which are often used in industrial applications.

Codes often confused with 2908.92
Common mistake. DNOC is often misclassified under 380893 (herbicides) or 380891 (insecticides) when it is prepared as a finished pesticide product. Within Chapter 29, it might be confused with other nitrated phenols under 290899. However, because DNOC is specifically named in the 290892 subheading, that specific code must be used over the general "other" categories.
Top exporters and importers of HS 290892 (the code used for DNOC), 2025

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).
