Products classified under HTS 2922.29.06.00
m-Nitro-p-Anisidine
m-Nitro-p-anisidine is a chemically defined organic compound with both amino and oxygen functions, specifically listed under HTS 2922.29.06.00 as a fast color base. It serves as an intermediate in dye synthesis for producing vibrant, colorfast dyes used in textiles and inks.
m-Nitro-o-Anisidine
m-Nitro-o-anisidine, explicitly specified in HTS 2922.29.06.00, is an amino-phenol ether derivative used as a fast color base in azo dye manufacturing. Its structure features amino-naphthol-like properties with nitro and methoxy groups, fitting Chapter 29 oxygen-function amino-compounds.
Fast Red Base B (m-Nitro-p-Anisidine Derivative)
Fast Red Base B is a commercial fast color base derived from m-nitro-p-anisidine, classified under HTS 2922.29.06.00 for its role in azo dye coupling. It produces wash-fast red shades on cotton and wool textiles.
Fast Blue Base R Salt
Fast Blue Base R, a diazotizable salt of m-nitro-o-anisidine, falls under HTS 2922.29.06.00 as a fast color base per Chapter 29 note 2(h). Used in cold dyeing processes for stable blue hues in printing inks and textiles.
Fast Garnet GBC Base
Fast Garnet GBC is a m-nitro-p-anisidine-based fast color base under HTS 2922.29.06.00, employed in pigment production for coatings and plastics. Its structure ensures high fastness to light and washing in final colorants.
Aniline Blue Fast Base
Aniline Blue Fast Base, derived from m-nitro-o-anisidine, is classified in HTS 2922.29.06.00 as a fast color base for producing brilliant blue dyes. It complies with Chapter 29 for oxygen-function amino-compounds used in textile coloration.
Fast Scarlet Base R
Fast Scarlet Base R is a fast color base from m-nitro-p-anisidine under HTS 2922.29.06.00, ideal for scarlet azo dyes with excellent fastness properties. Used primarily in leather and paper dyeing industries.
