Products classified under HTS 2908.99.12.00
Linear Alkylbenzene Sulfonic Acid (LABSA)
LABSA is a sulfonic acid derivative of linear alkylbenzene, falling under 2908.99.1200 as it contains only sulfo groups from phenol-alcohol derivatives. Widely used as an intermediate for manufacturing biodegradable detergents. Its chemically defined structure distinguishes it from formulated products.
Sodium Xylenesulfonate
Sodium salt of xylenesulfonic acid, a sulfonated alkylbenzene derivative under HTS 2908.99.1200. Functions as hydrotrope in liquid detergents to prevent phase separation. Chemically defined structure with only sulfo groups per chapter requirements.
Dioctyl Sodium Sulfosuccinate (DOSS)
Anionic surfactant with sulfosuccinate ester structure, classified under 2908.99.1200 as sulfo derivative per note 5(A) ester classification. Used in pharmaceuticals, food emulsification, and industrial wetting agents. Single sulfo group maintains chapter 29 status.
Ammonium Lauryl Sulfate
Sulfate ester of lauryl alcohol with ammonium counterion, falling under 2908.99.1200 as sulfo derivative salt. Common in personal care foaming products. Chemically defined per chapter 29 note 2(a).
Sodium Dodecylbenzenesulfonate
An anionic surfactant consisting of a sulfonated alkylbenzene chain with sodium salt formation, classified under HTS 2908.99.1200 as a derivative containing only sulfo groups. Used primarily in laundry detergents and cleaning formulations for its emulsifying properties. Meets chapter 29 requirements for chemically defined organic sulfonates.
Calcium Dodecylbenzenesulfonate
A calcium salt of dodecylbenzenesulfonic acid, classified in 2908.99.1200 per chapter note 5(C) for organic salts of sulfo-group compounds. Used as emulsifier in lubricants and agricultural formulations. Qualifies as chemically defined with only sulfo functionality.
