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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not meeting surface-active test
Sulfonic acids failing Chapter 34 Note 2 (surface tension reduction) classify as sulfonated aromatic hydrocarbons.
If higher fatty alcohol linear alkylbenzene sulfonates
Subheading specifies alcohol-derived variants; pure hydrocarbon-chain LABSA stays in 3402.31.
If diluted for scouring powders
LABSA acids dispersed in powder form become metal polishes or scouring preparations.

Import Tips & Compliance
• Classify based on alkyl chain length analysis; C10-C13 chains qualify as linear alkylbenzene sulfonic acids
• Ship as UN 2790 corrosive liquid; require proper drum labeling and ensure importer has EPA registration if for pesticide emulsifiers

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.
Tri-Isopropanolamine Neutralized LABSA (Acid Form Base)
Partially neutralized LABSA using TIPA, retained in acid form for pH-sensitive formulations like metal cleaners. Falls under HTS 3402.31.90.00 as 'other' linear alkylbenzene sulfonic acids. Provides corrosion inhibition alongside surfactant action.
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.
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.
