Products classified under HTS 2927.00.50.00
Fast Yellow GC Base Diazo Compound
Fast Yellow GC Base is a diazo compound used as a dye intermediate in the production of yellow azo pigments for textiles and inks. It falls under HTS 2927.00.50.00 as a diazo-compound not specifically provided for elsewhere in heading 2927. This chemical is a separate, chemically defined organic compound containing the diazo functional group.
Diazo Red B Base
Diazo Red B Base is an aromatic diazonium salt used in coupling reactions to produce red azo dyes for printing inks and plastics. Classified under HTS 2927.00.50.00 as 'other' diazo-compounds, it meets Chapter 29 requirements for separate chemically defined organic compounds. The diazo group (-N2+) defines its chemical identity.
Azoxybenzene
Azoxybenzene (C6H5N(O)NC6H5) is an azoxy compound used as a reagent in organic synthesis and as an intermediate for liquid crystal materials. It qualifies for HTS 2927.00.50.00 as an azoxy-compound, being a separate chemically defined organic compound per Chapter 29 note (a). The azoxy functional group distinguishes it from other nitrogen compounds.
4-Methoxybenzenediazonium Tetrafluoroborate
This stable diazonium salt serves as a Sandmeyer reaction intermediate and photoinitiator precursor in polymer chemistry. HTS 2927.00.50.00 covers it as a diazo-compound salt, with classification following the organic diazo component per Chapter 29 note on salts. The tetrafluoroborate counterion doesn't alter the organic compound classification.
p-Nitrobenzenediazonium Fluoborate
Used in pigment manufacturing and as a reagent for azo coupling, this nitro-substituted diazonium salt falls under HTS 2927.00.50.00. The diazo function takes precedence over nitro group per Chapter 29 classification rules. It's supplied as a stable solid for industrial dye synthesis.
Benzeneazodimethylaniline (Solvent Yellow 2)
This azo compound serves as a solvent dye for petroleum products and plastics coloration. Although used as coloring matter, its import as pure chemical compound classifies under HTS 2927.00.50.00 per Chapter 29 precedence over Chapter 32. The azo (-N=N-) linkage defines its chemical heading.
4-(Phenylazo)aniline
An aminoazobenzene derivative used as a dye intermediate and coupling component in azo pigment synthesis. HTS 2927.00.50.00 applies as an azo-compound with the characteristic -N=N- linkage between aromatic rings. Meets Chapter 29 requirements for chemically defined organic compounds.
1-Phenylazo-2-naphthol (Sudan I)
Sudan I is a fat-soluble azo dye historically used in solvents and oils, imported as reference standard or synthesis intermediate. Classifies under HTS 2927.00.50.00 as a pure azo-compound rather than finished coloring matter. The trans-azo configuration defines its chemical identity.
Diazo Blue B Base
Industrial diazo component for producing blue azo dyes used in textiles and paper. HTS 2927.00.50.00 covers this 'other' diazo-compound as a separate organic chemical for dye synthesis. Requires cold storage to maintain reactivity.
4-(2,4-Dimethylphenylazo)benzoic Acid
A carboxylic acid azo compound used in liquid crystal dyes and polymer additives. Falls under HTS 2927.00.50.00 with azo function taking precedence over carboxylic acid per Chapter 29 numerical order rule. Supplied as yellow crystalline powder.
Methyl Orange Diazo Component
Primary diazo salt used in synthesis of pH indicator Methyl Orange and similar azo dyes. HTS 2927.00.50.00 as diazo-compound intermediate meeting Chapter 29 purity standards. Light-sensitive - amber packaging required.
Fast Scarlet Base G Diazo Salt
Diazonium salt for scarlet azo pigment production in printing inks. Classifies HTS 2927.00.50.00 as separate diazo-compound with tetrafluoroborate stabilization. High purity grade for consistent coupling.
Azobenzene-4-sulfonic Acid
Water-soluble azo compound used in direct dyes and analytical chemistry. HTS 2927.00.50.00 despite sulfonation, as azo function occurs later in chapter order. Provided as sodium salt.
2,4-Diaminoazobenzene
Diamino-substituted azo compound used as dye intermediate and hair colorant precursor. HTS 2927.00.50.00 for azo-compound with multiple amino groups. Regulated for potential carcinogenicity.
p-Hydroxyazobenzene
Phenolic azo compound used in polymer dyes and as UV absorber. Classifies HTS 2927.00.50.00 with azo precedence over phenolic function. Pale yellow solid.
