U.S. imports of linear alkylbenzene sulfonic acids and their salts (HS 340231) totaled $7.5M in July 2026, traded with 38 countries.
Importers of Linear Alkylbenzene Sulfonic Acids and Their Salts paid $703K in duties in July 2026 — an effective duty rate of 13% on $5.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataLinear alkylbenzene sulfonic acids (LABSA) and their salts — the dominant anionic surfactant feedstock for household and industrial detergent manufacturing — are split at the US 10-digit level between sulfonates (3402311000) and other sulfonic acid/salt forms (3402319000). LABSA is a high-volume petrochemical intermediate, and imports from certain origins have historically attracted antidumping scrutiny in global markets, making origin documentation and producer certification important for US importers. The linear (biodegradable) structure is the defining technical characteristic that separates these compounds from branched-chain alkylbenzene sulfonates classified elsewhere.

Tariff line 3402311000 covers linear alkylbenzene sulfonates (the neutralized salt form, typically sodium LAS), which is the finished surfactant active used directly in detergent formulations. Line 3402319000 covers the sulfonic acid form (LABSA) and other salt variants. The distinction matters because the acid form is an intermediate requiring further neutralization, while the sulfonate salt is ready for compounding — affecting both classification and downstream processing declarations.
As of recent trade schedules, no active US antidumping or countervailing duty orders specifically target linear alkylbenzene sulfonates under heading 340231, but importers should verify current CBP and Commerce Department order lists at the time of entry, as trade-remedy coverage can change. Origin documentation from the producer is advisable given the global sensitivity of this commodity.
