Products classified under HTS 2902.90.30.10
Linear Dodecylbenzene (LDB)
Linear dodecylbenzene is a chemically defined organic compound consisting of a benzene ring alkylated with a straight-chain C12 hydrocarbon group. It falls under HTS 2902.90.30.10 as an alkylbenzene used primarily as an intermediate in producing linear alkylbenzene sulfonates (LAS) for detergents. The chapter notes confirm classification for separate chemically defined cyclic hydrocarbons with alkyl substituents.
Normal Dodecylbenzene (n-DDB)
Normal dodecylbenzene is a straight-chain alkylbenzene (C6H5-C12H25) used exclusively as a feedstock for manufacturing biodegradable detergent surfactants. Classified under HTS 2902.90.30.10 per Chapter 29 notes for pure, separate alkylbenzenes. Excludes sulfonated forms which shift to Chapter 34.
Technical Grade Dodecylbenzene 98%
Technical grade dodecylbenzene at 98% purity, primarily linear C12-benzene, serves as direct precursor for sulfonation in household detergent production. HTS 2902.90.30.10 applies as it meets Chapter 29 criteria for chemically defined alkylbenzenes with impurities not affecting principal characteristics.
LAB-120 Dodecylbenzene
LAB-120 is a commercial linear dodecylbenzene grade with average C12 chain length, optimized for high-yield sulfonation in powder laundry detergents. Classifies under 2902.90.30.10 as pure alkylbenzene per Chapter 29 note (a), excluding formulated mixtures.
DDB for Detergent Manufacture
Industrial dodecylbenzene specifically produced via HF-alkylation for conversion to dodecylbenzene sulfonic acid (DDBSA). Meets HTS 2902.90.30.10 as chemically defined alkylbenzene; chapter notes exclude sulfonated derivatives.
