Nitrobenzene
Nitrobenzene is a pale yellow liquid organic compound with the formula C6H5NO2, produced by nitration of benzene. It falls under HTS 2904.20.5000 as a sulfonated/nitrated derivative of hydrocarbons containing only nitro groups, used primarily as an intermediate in aniline production. This classification applies to pure nitrobenzene not covered by more specific subheadings.
Nitromethane
Nitromethane (CH3NO2) is a simple nitroalkane used as a solvent, fuel additive, and chemical intermediate. It qualifies under HTS 2904.20.5000 as a nitrated derivative of hydrocarbons (methane) containing only nitro groups. Chapter notes confirm acyclic nitro compounds belong here.
2-Nitrotoluene
2-Nitrotoluene (o-nitrotoluene, C7H7NO2) is an isomeric nitro derivative of toluene used in explosives and dyes. Falls under HTS 2904.20.5000 as 'other' nitrated aromatic hydrocarbon with single nitro group. Distinguished from dinitro derivatives.
4-Nitrobiphenyl
4-Nitrobiphenyl (C12H9NO2) is a nitrated derivative of biphenyl used in research and as a synthetic intermediate. Classified in HTS 2904.20.5000 for its single nitro group on polycyclic aromatic hydrocarbon base. Meets chapter 29 purity requirements.
1-Nitropropane
1-Nitropropane (C3H7NO2) functions as an industrial solvent and chemical intermediate. HTS 2904.20.5000 applies to this acyclic nitrated hydrocarbon with only nitro functionality. Excluded from chapter 27 petroleum mixtures.
Dinitrobenzene (mixed isomers)
Mixed dinitrobenzene isomers (1,3- and 1,4-) are nitrated hydrocarbon derivatives used in dye and explosive manufacture. While containing two nitro groups, classified under HTS 2904.20.5000 'other' as not separately specified. Chapter note 3 prioritizes last numerical heading.
