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.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for amino-naphthols instead of amino-phenols
Amino-naphthols have dedicated earlier subheading 2922.19, taking precedence over 'other' per numerical order note.
If esterified with acyclic alcohols
Esters of phenolic acids classify with the acid or later compound per Chapter 29 ester note (A).
If converted to sugar ethers/esters
Sugar derivatives of phenols move to 2940, excluded from general amino-phenol scope.

Import Tips & Compliance
• Use NMR or HPLC certificates to confirm meta isomer, preventing confusion with ortho/para forms under same HTS
• Label as hazardous (toxic/phenolic) per GHS; ensure UN packaging for air/sea import
• Monitor for sulfonated impurities, which could shift to earlier halogenated/sulfonated derivatives

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.
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.
