Products classified under HTS 2921.42.18.00
o-Aminobenzenesulfonic Acid (Orthanilic Acid)
Orthanilic acid is a chemically defined aromatic monoamine derivative with both amino and sulfonic acid groups on a benzene ring, explicitly listed under HTS 2921.42.18.00. It serves as a key intermediate in dye synthesis and pharmaceutical production. This classification applies due to its specific structure as an aniline derivative and salt thereof.
2,4-Dichloroaniline
2,4-Dichloroaniline is a halogenated aromatic monoamine explicitly named in HTS 2921.42.18.00, featuring two chlorine atoms on the aniline benzene ring. Used primarily in herbicide and dye manufacturing. Falls under this code as a derivative of aniline per Chapter 29 heading 2921.
p-Fluoroaniline
p-Fluoroaniline (4-fluoroaniline) is a fluorinated aniline derivative explicitly included in HTS 2921.42.18.00. Essential intermediate for pharmaceuticals like fluoroquinolone antibiotics and agrochemicals. Classified here as an aromatic monoamine per Chapter 29 provisions.
m-Nitroaniline
m-Nitroaniline (3-nitroaniline) is a nitrated aromatic monoamine specifically listed under HTS 2921.42.18.00. Widely used in azo dye production and as a corrosion inhibitor. Qualifies as an aniline derivative per Chapter 29 heading 2921.
N,N-Diethylmetanilic Acid
N,N-Diethylmetanilic acid is a quaternary aniline derivative with both diethylamino and sulfonic acid groups, explicitly named in HTS 2921.42.18.00. Used in specialty dye and surfactant synthesis. Classified as aromatic monoamine derivative per Chapter 29.
2-Chloro-5-nitroaniline
