U.S. imports of sulfonated, nitrated, or nitrosated derivatives of hydrocarbons (SITC 51140) totaled $15.1M in April 2026, traded with 21 countries.
Importers of Sulfonated, Nitrated, or Nitrosated Derivatives of Hydrocarbons paid $2.3M in duties in April 2026 — an effective duty rate of 16% on $14.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Sulfonated, Nitrated, or Nitrosated Derivatives of Hydrocarbons imports of $15.1M in April 2026 ran 47% above the year-to-date monthly average of $10.3M.
Last updated: April 2026 dataSulfonated, nitrated, and nitrosated hydrocarbon derivatives span a wide commercial spectrum — from nitrobenzene and nitrotoluenes used as dye and pharmaceutical intermediates to linear alkylbenzene sulfonates (LAS) that are the backbone of synthetic detergent formulations. Nitrated aromatic compounds in particular may be subject to ATF or DOT precursor-chemical controls depending on their potential use in energetic materials, adding a compliance layer beyond standard TSCA requirements. Importers should verify whether specific substances in this grouping are listed on any controlled-precursor or watch-list registry before shipment.

Certain nitrated compounds can serve as precursors to explosives and may be subject to reporting or permit requirements under DEA, ATF, or DHS chemical-facility security programs. Importers should screen their specific substance against the DEA List I and List II chemicals, ATF explosive precursor lists, and DHS CFATS chemicals of interest before importing.
LAS are the most widely used anionic surfactants in household and industrial detergents, produced by sulfonating linear alkylbenzene. They fall within the sulfonated derivatives grouping under SITC 51140. Importers of LAS should confirm the degree of sulfonation and chain-length distribution, as these parameters affect both product performance specifications and the applicable HTS subheading.
