Products classified under HTS 2922.29.61.00
4-Aminophenol
4-Aminophenol is a chemically defined organic compound featuring both amino (-NH2) and hydroxyl (-OH) oxygen functions on a benzene ring, classifying it as an amino-phenol under heading 2922. It is commonly used as an intermediate in pharmaceutical and dye manufacturing. This product falls under 2922.29.61.00 due to its inclusion in additional U.S. note 3 to section VI for specific regulatory tracking.
2-Aminophenol Hydrochloride Salt
2-Aminophenol hydrochloride is the salt form of an amino-phenol, where the oxygen-function amino-compound is protonated and paired with HCl, classified under 2922 per chapter note on salts. Used in synthesis of pharmaceuticals, dyes, and rubber antioxidants. Its inclusion in additional U.S. note 3 places it specifically in subheading 2922.29.61.00.
p-Aminophenol Sulfate
p-Aminophenol sulfate is the sulfuric acid salt of 4-aminophenol, an oxygen-function amino-compound under heading 2922, with salts classified with the parent compound. Primarily used in photographic developers and hair dye intermediates. Subject to additional U.S. note 3, hence 2922.29.61.00.
N-Acetyl-4-Aminophenol (Paracetamol Intermediate)
N-Acetyl-4-aminophenol, a derivative ether/ester of amino-phenol with acetyl oxygen function, remains under 2922.29 as it contains only one kind of oxygen function beyond the phenol. Key precursor for acetaminophen synthesis. Covered by additional U.S. note 3 for this subheading.
2-Aminophenol
2-Aminophenol (o-aminophenol) is an amino-phenol with adjacent amino and hydroxy groups, a classic oxygen-function amino-compound of heading 2922. Widely used in azo dye and pharmaceutical synthesis. Classified in 2922.29.61.00 per U.S. note 3.
4-Aminophenol Hydrochloride
4-Aminophenol hydrochloride salt features the amino-phenol base with single oxygen function, classified with parent under 2922 salts provision. Used in polymer and dye production. Specific to 2922.29.61.00 via additional note 3.
m-Aminophenol
m-Aminophenol (3-aminophenol) is the meta isomer amino-phenol under 2922.29, used in hair dyes and pharmaceuticals. Chemically defined with single oxygen function. Falls under U.S. note 3 subheading.
2,4-Diaminophenol Dihydrochloride
2,4-Diaminophenol dihydrochloride is a di-amino phenol salt, still single oxygen function type under 2922.29. Used in oxidative hair dyes. Note 3 specific.
4-Methylaminophenol Sulfate (Metol)
Metol (4-methylaminophenol sulfate) is N-substituted amino-phenol ether equivalent, heading 2922. Photographic developer. U.S. note 3.
2-Aminoresorcinol
2-Aminoresorcinol (2-amino-1,3-benzenediol) technically has two OH but classified as amino-phenol derivative if single primary function. Dye intermediate.
N-(4-Hydroxyphenyl)acetamide
N-(4-Hydroxyphenyl)acetamide, acetaminophen analog, oxygen-function amino-compound ester. Pharmaceutical use.
3-Aminophenol
3-Aminophenol, meta isomer for specialty dyes.
2,5-Diaminophenol
2,5-Diaminophenol for hair dye synthesis.
4-Amino-2-methylphenol
4-Amino-2-methylphenol, substituted amino-phenol.
p-Phenylenediamine Derivative (Hydroxy)
Hydroxy derivative of p-phenylenediamine as amino-phenol.
