U.S. imports of Sulfonated, Nitrated & Nitrosated Hydrocarbon Derivatives (Mixed/Other) (HS 290499) totaled $554K in August 2026, imported from 12 countries.
Importers of Sulfonated, Nitrated & Nitrosated Hydrocarbon Derivatives (Mixed/Other) paid $113K in duties in August 2026, an average duty rate of 20.46% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Sulfonated, Nitrated & Nitrosated Hydrocarbon Derivatives (Mixed/Other) imports of $554K in August 2026 ran 27% below the year-to-date monthly average of $762K.
Last updated: August 2026 dataHydrocarbon derivatives bearing combinations of sulfo, nitro, or nitroso groups — or those not elsewhere specified — are captured in this residual heading, which covers commercially important compounds such as monochloromononitrobenzenes (2904990400 and 2904990800) and nitrotoluenesulfonic acids (2904992000). China and India together dominate US supply, reflecting their established fine-chemicals export capacity. The heading's structure separates aromatic products described in Additional Note 3 to Section VI (2904994000) from other aromatic derivatives (2904994700) and non-aromatic mixed derivatives (2904995000), so precise structural characterization is essential for correct classification.

Headings 2904.10 and 2904.20 are reserved for derivatives bearing only sulfo groups or only nitro/nitroso groups, respectively. Once a compound carries more than one type of these functional groups — or combines them with halogens — it falls into the 2904.99 residual category. A licensed customs broker or chemist familiar with HTS Section VI notes should review the molecular structure before filing.
Monochloromononitrobenzenes are key intermediates in the synthesis of aniline derivatives, agrochemicals, and pharmaceutical compounds. Their separate enumeration across two tariff lines (2904990400 and 2904990800) reflects their commercial volume and the need to distinguish specific isomers from the broader group.
