Products classified under HTS 2922.29.81
p-Aminophenol
p-Aminophenol is a key intermediate chemical with both amino and phenolic hydroxyl oxygen functions, used primarily in the production of dyes, pharmaceuticals, and photographic developers. It falls under HTS 2922.29.81 as an amino-phenol (other than those with multiple oxygen functions) that is chemically defined and separate as per Chapter 29 notes. This classification applies to its pure form or with stabilizers necessary for transport.
2-Aminophenol (o-Aminophenol)
2-Aminophenol, also known as o-aminophenol, is an organic compound featuring an amino group ortho to a phenolic hydroxyl group, widely used as a dye intermediate and in rubber antioxidants. Classified under HTS 2922.29.81 as 'other' amino-phenols without multiple oxygen functions, it qualifies as a separate chemically defined compound under Chapter 29. Its ethers or esters would also fall here unless specified otherwise.
4-Aminophenol Hydrochloride Salt
4-Aminophenol hydrochloride is the salt form of p-aminophenol, used in hair dyes, pharmaceuticals, and as a polymer intermediate, featuring amino and phenolic functions. It is classified under HTS 2922.29.81 as salts thereof of amino-phenols, per Chapter 29 note (C)(1) directing inorganic salts to the organic compound's heading. This ensures consistency with the base amino-phenol classification.
m-Aminophenol
m-Aminophenol (3-aminophenol) is utilized in the synthesis of azo dyes, pharmaceuticals, and as a corrosion inhibitor, with its single amino and phenolic oxygen functions. It fits HTS 2922.29.81 as 'other' amino-phenols, being a separate chemically defined organic compound without multiple oxygen types. Meta substitution distinguishes it but keeps it in this specific subheading.
N-(4-Hydroxyphenyl)acetamide (Paracetamol Intermediate)
N-(4-Hydroxyphenyl)acetamide, a key paracetamol synthesis intermediate, has phenolic OH and amide (oxygen) but classified here if amino-phenol nature prevails. Under HTS 2922.29.81 as amino-phenol derivative with single oxygen type consideration. Chapter notes place it last in order among applicable oxygen-function amino-headings.
4-Aminoresorcinol (1,3-Dihydroxy-4-aminobenzene)
4-Aminoresorcinol has amino and two phenolic OH groups but classified as amino-phenol if not multiple kinds. HTS 2922.29.81 for 'other' provided context fits single oxygen function type. Used in dyes and cosmetics.
p-Phenetidine (4-Ethoxyaniline)
p-Phenetidine is the ethyl ether of p-aminophenol, used in dye and pharma intermediates. HTS 2922.29.81 as 'ethers' of amino-phenols.
2,4-Diaminophenol Dihydrochloride
2,4-Diaminophenol salt used in oxidation dyes. Dual amino but phenolic oxygen classifies here.
Acetaminophen Impurity A (4-Aminophenol)
Pharma impurity standard, pure 4-aminophenol form.
Hydroquinone Monobenzyl Ether (related amino precursor)
Derivative ether used in cosmetics, amino-phenol ether analog.
4-(Aminomethyl)phenol
Amino-alcohol phenol hybrid, borderline classification.
Phenylephrine Base (amino-phenol analog)
Pharma intermediate with phenolic OH and amino.
Tyramine Hydrochloride
Phenethylamine derivative with phenolic OH, used in research.
p-Aminophenol Acetate Ester
p-Aminophenol acetate is an ester derivative where the phenolic hydroxyl is acetylated, used in fine chemical synthesis and as a stabilizer. Classified under HTS 2922.29.81 as 'ethers and esters' of amino-phenols (single oxygen function type), it remains with the parent amino-phenol per Chapter 29 classification rules. This avoids separation into alcohol ester headings.
2-Aminophenol-4-Sulfate (limited impurities)
2-Aminophenol-4-sulfate is a derivative used in dye coupling, with sulfate group but classified as amino-phenol if not principally sulfonated. It falls under HTS 2922.29.81 as 'other' provided sulfonation doesn't dominate per heading 2930 exclusion notes. Meets Chapter 29 as chemically defined with single oxygen function emphasized.
