Products classified under HTS 3402.31.10.00
Linear Alkylbenzene Sulfonic Acid (LABSA)
LABSA is a primary anionic surfactant used in detergent manufacturing, characterized by its aromatic structure and water solubility that meets heading 3402 criteria. It functions by reducing surface tension to facilitate cleaning. Classified under 3402.31.10.00 due to its aromatic or modified aromatic composition as a linear alkylbenzene sulfonic acid.
Dodecylbenzene Sulfonic Acid (DDBSA)
DDBSA is a modified aromatic sulfonic acid serving as a key ingredient in liquid laundry detergents and industrial cleaners. Its anionic properties enable effective emulsification and dirt removal per heading 3402 definitions. Falls under 3402.31.10.00 as an aromatic linear alkylbenzene sulfonic acid or salt.
Sodium Dodecylbenzene Sulfonate (SDDBS)
SDDBS is the sodium salt form of dodecylbenzene sulfonic acid, widely used as an emulsifier in pesticides and household cleaners. It qualifies as an anionic surface-active agent under heading 3402 due to its solubility and tension-reducing properties. Specifically classified in 3402.31.10.00 for aromatic linear alkylbenzene sulfonates.
LABSA 96% Concentrate
This 96% active LABSA concentrate is a dark brown viscous liquid used in formulating dishwashing liquids and industrial degreasers. Its aromatic sulfonic acid structure aligns with 3402.31.10.00 specifications for anionic agents. Excludes soap per Chapter notes, focusing on pure surfactant properties.
Modified Toluene Sulfonic Acid Surfactant
A modified aromatic sulfonic acid derived from toluene, used in textile dyeing auxiliaries and emulsifiers. Meets 3402 criteria for organic surface-active agents with required surface tension reduction. Placed in 3402.31.10.00 for its aromatic or modified aromatic sulfonic acid nature.
C12-C14 Alkylbenzene Sulfonic Acid
This C12-C14 chain length aromatic sulfonic acid is standard in heavy-duty liquid detergents and car wash formulations. Its anionic character and solubility define it under heading 3402. Specifically 3402.31.10.00 for linear alkylbenzene sulfonic acids.
Ammonium Linear Alkylbenzene Sulfonate
Ammonium salt of LABSA used in low-foam industrial cleaners and agricultural emulsifiers. Qualifies as aromatic sulfonic salt per 3402.31.10.00 with water dispersibility and surfactant performance. Distinguished from soaps by Chapter definitions.
Triethanolamine Dodecylbenzene Sulfonate
TEA salt of DDBSA provides mildness in personal care emulsifiers and liquid soaps (non-soap surfactant). Aromatic structure fits 3402.31.10.00; excludes true soaps per note to 3401. Used where lower irritation needed.
Calcium Dodecylbenzene Sulfonate
Calcium salt form used as corrosion inhibitor in lubricants and overbased detergents. Still classifies as anionic surfactant under 3402.31.10.00 despite end-use. Meets surface activity tests.
Methyl Ester Sulfonate Alternative (Aromatic Modified)
Modified aromatic version combining MES with LABSA structure for eco-friendly detergents. Dual functionality but primarily classified by aromatic sulfonic component in 3402.31.10.00.
