U.S. exports of Sulfonated Hydrocarbon Derivatives (Sulfo Groups Only) (HS 290410) totaled $8.8M in August 2026.
Importers of Sulfonated Hydrocarbon Derivatives (Sulfo Groups Only) paid $310K in duties in August 2026, an average duty rate of 13.29% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataAromatic and non-aromatic hydrocarbon derivatives bearing only sulfo groups — including sulfonic acids, sulfonyl chlorides, and their salts and esters — are key intermediates in dye, detergent, and pharmaceutical synthesis. The US schedule breaks this heading into eight distinct 10-digit lines, ranging from 2-anthracenesulfonic acid (2904100400) and benzenesulfonyl chloride (2904100800) to naphthalenetrisulfonic acid mixtures (2904101500) and residual non-aromatic derivatives (2904105000). Germany and France are the leading suppliers, reflecting Europe's deep fine-chemicals manufacturing base, with Belgium and India also significant sources. Importers should note that certain aromatic derivatives listed under US Additional Note 3 to Section VI carry separate tariff treatment under line 2904103200.

The US schedule separates aromatic derivatives — including those specifically enumerated in Additional Note 3 to Section VI (line 2904103200) and other aromatic derivatives (2904103700) — from non-aromatic sulfonated derivatives, which fall under line 2904105000. Correct classification depends on whether the parent hydrocarbon structure is aromatic or aliphatic.
These compounds serve as intermediates in the production of azo dyes, optical brighteners, surfactants, and pharmaceutical active ingredients. Benzenesulfonyl chloride, for example, is widely used in agrochemical and pharmaceutical synthesis, while naphthalenetrisulfonic acid mixtures are important in textile dye manufacturing.
