U.S. exports of anionic organic surface-active agents (other than linear alkylbenzene sulfonates) (HS 340239) totaled $23.3M in July 2026.
Importers of Anionic Organic Surface-Active Agents (Other Than Linear Alkylbenzene Sulfonates) paid $1.8M in duties in July 2026 — an effective duty rate of 12% on $15.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Anionic Organic Surface-Active Agents (Other Than Linear Alkylbenzene Sulfonates) imports of $18.3M in July 2026 ran 27% above the year-to-date monthly average of $14.4M.
Last updated: July 2026 dataAnionic surfactants beyond the linear alkylbenzene sulfonate family — including sulfated alcohols, sulfated polyethers, and other non-aromatic anionic actives — are classified under heading 340239, which the US schedule subdivides into aromatic/modified-aromatic types (3402391000) and several non-aromatic lines covering salts of sulfated alcohols (3402399010), salts of sulfated polyethers (3402399020), and a residual NESOI category (3402399050). These compounds serve as key actives in shampoos, emulsifiers, and industrial cleaners, and the aromatic vs. non-aromatic distinction drives the 10-digit classification. Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), two of the most widely traded anionic surfactants globally, typically fall within the non-aromatic sulfated-alcohol and sulfated-polyether lines respectively.

SLES is an ethoxylated (polyether) sulfate, so it generally falls under 3402399020 — salts of sulfated polyethers — rather than the sulfated-alcohol line. Sodium lauryl sulfate (SLS), which lacks the ethylene oxide chain, is typically classified under 3402399010 as a salt of a sulfated alcohol. Confirming the degree of ethoxylation in the product specification is essential for correct line selection.
A technical data sheet or certificate of analysis showing the molecular structure — specifically whether the compound contains a benzene ring or modified aromatic nucleus — is the primary evidence. Supplier-issued product specifications, REACH registration dossiers, or CAS number cross-references can support the aromatic determination. CBP may request a laboratory analysis if the aromatic character is not evident from commercial documents.
