Products classified under HTS 2904.99.47.00
p-Toluenesulfonic Acid
p-Toluenesulfonic acid (PTSA) is a strong organic acid with the formula CH3C6H4SO3H, featuring a sulfonated aromatic hydrocarbon structure (toluene derivative). It falls under HTS 2904.99.47.00 as a sulfonated derivative of an aromatic hydrocarbon, used primarily as a catalyst in esterification and dehydration reactions.
Benzenesulfonic Acid
Benzenesulfonic acid is a sulfonated derivative of benzene (C6H5SO3H), a key intermediate in dye and detergent production. Classified under HTS 2904.99.47.00 as an 'other' aromatic sulfonated hydrocarbon derivative not specified elsewhere in heading 2904.
Nitrotoluene (Mixture of Isomers)
Nitrotoluene consists of ortho-, meta-, and para-nitrotoluene isomers (CH3C6H4NO2), nitrated derivatives of toluene. Falls under HTS 2904.99.47.00 as aromatic nitrated hydrocarbons, used in explosives, dyes, and pharmaceutical intermediates.
Dodecylbenzenesulfonic Acid
Dodecylbenzenesulfonic acid (DDBSA) is an alkylbenzene sulfonated derivative used as a surfactant in detergents. Classified in HTS 2904.99.47.00 as a sulfonated aromatic hydrocarbon, whether halogenated or not, covering alkyl chain variants.
2,4-Dinitrotoluene
2,4-Dinitrotoluene (2,4-DNT) is a dinitrated toluene derivative used in polyurethane production and as explosive intermediate. It qualifies under HTS 2904.99.47.00 as a nitrated aromatic hydrocarbon derivative.
Dinonylnaphthalenesulfonic Acid
Dinonylnaphthalenesulfonic acid (DNNSA) is a branched alkyl naphthalene sulfonate used in oil additives and extractants. Falls under HTS 2904.99.47.00 as an aromatic sulfonated hydrocarbon derivative.
Nitrobenzene
Nitrobenzene (C6H5NO2) is the simplest nitrated aromatic hydrocarbon, used in aniline production and as solvent. Classified under HTS 2904.99.47.00 as an 'other' nitrated aromatic hydrocarbon.
Cumene Hydroperoxide (95% Pure)
Cumene hydroperoxide is an organic peroxide derived from cumene (isopropylbenzene), potentially classifiable as nitrosated/nitrated equivalent through oxygen substitution. Used in phenol/acetone production, fits 2904.99.47.00 for specialized aromatic derivatives.
4-Nitrocumidine (Mixture)
4-Nitrocumidine refers to nitrated cumene derivatives with amino substitution, used in dye intermediates. Classifies under HTS 2904.99.47.00 prioritizing nitrated aromatic hydrocarbon character over nitrogen functions per chapter notes.
Chloronitrotoluene
Chloronitrotoluene combines chloro-halogenation with nitro groups on toluene, creating a compound derivative. Fits HTS 2904.99.47.00 explicitly covering halogenated nitrated aromatic hydrocarbons.
