Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fully neutralized to TIPA salt
Complete salt conversion moves to specific linear alkylbenzene sulfonate salts subheading.
If complex reaction mixture >95% byproducts
Chemical preparations not predominantly single surface-active agents go to 3824.

Import Tips & Compliance
• Titration analysis must show free acid content >50% to avoid salt subheading 3402.31.10
• Classify by predominant chemical identity; minor neutralization doesn't change base acid heading
• Ensure REACH/SVHC declarations if destined for EU; common error is classifying as soap (3401)

Linear Alkylbenzene Sulfonic Acid (LABSA 96%)
LABSA 96% is a highly concentrated anionic surfactant used as the primary ingredient in liquid laundry detergents and dishwashing liquids. It falls under HTS 3402.31.90.00 as 'other' linear alkylbenzene sulfonic acids, distinct from common salts like sodium LAS. This brown viscous liquid excels at reducing surface tension for superior cleaning performance.
C10-13 Linear Alkylbenzene Sulfonic Acid
Broad-cut LABSA with C10-C13 alkyl distribution, versatile for personal care emulsifiers and industrial degreasers. HTS 3402.31.90.00 applies to these 'other' chain length variants. Optimized for low-foam applications in machine dishwash.
Dodecylbenzene Sulfonic Acid (DDBSA)
DDBSA is a specific linear alkylbenzene sulfonic acid with C12 alkyl chain, widely used in emulsifiers for industrial cleaners and agricultural pesticides. Classified under HTS 3402.31.90.00 as 'other' LABSA variants beyond standard salts. Its strong acidity enables effective grease removal and wetting in formulations.
LABSA 90% Aqueous Solution
A 90% active LABSA solution in water, used in manufacturing cost-effective detergent bases for household and institutional cleaners. HTS 3402.31.90.00 covers this as 'other' linear alkylbenzene sulfonic acid, provided it meets the anionic surface-active definition. Lower concentration aids handling while maintaining emulsification properties.
High Active LABSA for Emulsion Polymerization
Ultra-pure LABSA (>98% active) designed for latex and paint emulsion stabilizers in polymerization processes. Specifically under HTS 3402.31.90.00 for industrial-grade linear alkylbenzene sulfonic acids. Minimal impurities ensure stable micelle formation.
