Products classified under HTS 3402.49.10.00
Dodecylbenzene Sulfonic Acid (DDBSA)
DDBSA is a modified aromatic sulfonic acid surfactant used primarily in household and industrial cleaners, classified under HTS 3402.49.10.00 due to its aromatic benzene ring structure. It provides superior emulsification and detergency in formulations.
Xylene Sulfonate Emulsifier
Xylene sulfonate serves as an aromatic emulsifier for industrial applications, meeting HTS 3402.49.10.00 criteria as a modified aromatic surface-active agent. Essential in emulsion polymerization and metalworking fluids.
Naphthalene Sulfonate Dispersant
Naphthalene sulfonate is a classic aromatic dispersant for pigments and dyes, classified in HTS 3402.49.10.00 due to its fused aromatic ring structure and surface-active properties. Key in concrete admixtures and ink manufacturing.
Linear Alkylbenzene Sulfonic Acid (LABSA)
LABSA is a synthetic anionic surfactant derived from linear alkylbenzene, featuring an aromatic structure that qualifies it as an aromatic organic surface-active agent under HTS 3402.49.10.00. It is widely used in detergent formulations for its excellent foaming and cleaning properties.
Sodium Dodecylbenzene Sulfonate (SDDBS)
SDDBS is the neutralized salt form of dodecylbenzene sulfonic acid, an aromatic anionic surfactant under HTS 3402.49.10.00. Commonly used in emulsifiers, wetting agents, and textile processing auxiliaries.
Alkylbenzene Sulfonate Surfactant Blend
This blend contains modified aromatic alkylbenzene sulfonates designed for industrial detergent manufacturing, falling under HTS 3402.49.10.00. It meets surface-active criteria with reduced surface tension in aqueous solutions.
Toluene Sulfonate Surfactant
Toluene-based sulfonate is a modified aromatic surfactant used in specialty cleaning formulations, classified in HTS 3402.49.10.00 for its aromatic hydrocarbon backbone. Provides effective wetting and dispersing properties.
Benzene Sulfonate Wetting Agent
This pure aromatic benzene sulfonate derivative acts as a high-performance wetting agent under HTS 3402.49.10.00. Used in agriculture, textiles, and coatings for rapid surface spreading.
