Ammonium Linear Alkylbenzene Sulfonate
Ammonium Linear Alkylbenzene Sulfonate is an anionic surfactant used in low-foam industrial cleaners and agricultural emulsifiers. Its ammonium salt form of LABSA provides water dispersibility and effective surface tension reduction, meeting the criteria for organic surface-active agents in heading 34.02. It is classified under this tariff item as an anionic surface-active agent other than sodium alkylbenzene sulphonates.
C10-13 Linear Alkylbenzene Sulfonic Acid
C10-13 Linear Alkylbenzene Sulfonic Acid is a broad-cut anionic surfactant used in personal care emulsifiers and industrial degreasers. Its alkyl chain distribution and aromatic sulfonic acid structure qualify it as an anionic organic surface-active agent under heading 34.02. This product falls under tariff item 3402.31.90 as 'Other' since it is not specifically a sodium alkylbenzene sulphonate for the manufacture of slow dissolving toilet tank solids.
C12-C14 Alkylbenzene Sulfonic Acid
C12-C14 Alkylbenzene Sulfonic Acid is a linear alkylbenzene sulfonic acid used in heavy-duty liquid detergents and car wash formulations. Its anionic character and water solubility make it a classic organic surface-active agent under heading 34.02. It is classified here as an anionic surface-active agent other than the sodium salt form.
Calcium Dodecylbenzene Sulfonate
Calcium Dodecylbenzene Sulfonate is a calcium salt of dodecylbenzene sulfonic acid used as a corrosion inhibitor in lubricants and as an overbased detergent. Despite its end-use, it retains anionic surfactant properties and meets the surface activity tests of Chapter 34. It is classified here as an anionic surface-active agent other than the sodium salt.
Dodecylbenzene Sulfonic Acid (DDBSA)
Dodecylbenzene Sulfonic Acid (DDBSA) is a key anionic surfactant used in liquid laundry detergents and industrial cleaners. Its aromatic sulfonic acid structure provides effective emulsification and dirt removal, meeting the criteria for organic surface-active agents in heading 34.02. It is classified here as an anionic surface-active agent other than the sodium salt.
High Active LABSA for Emulsion Polymerization
High Active LABSA for Emulsion Polymerization is an ultra-pure (>98% active) linear alkylbenzene sulfonic acid designed for latex and paint emulsion stabilizers. Its high purity and industrial-grade quality make it suitable as an anionic surface-active agent under heading 34.02. It is classified under 3402.31.90 as 'Other' because it does not meet the specific sodium salt or end-use requirements of the sibling item.
