4-Aminophenol
4-Aminophenol is a chemically defined organic compound featuring both amino (-NH2) and hydroxy (-OH) groups attached to a benzene ring, classifying it as an oxygen-function amino-compound under heading 2922. It contains only one type of oxygen function (phenol) and no additional oxygen groups. Commonly used as an intermediate in pharmaceutical and dye production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing more than one oxygen function (e.g., additional keto group)
Compounds with multiple oxygen functions like amino-hydroxy-ketones classify under 2921 per chapter note on oxygen functions.
If supplied as hydrochloride salt
Organic salts of oxygen-function amino-compounds classify with the parent compound under note on salts (C)(1).

Import Tips & Compliance
• Verify purity certificate (≥98%) to confirm chemical definition per Chapter 29 note (a); impurities must not alter classification
• Include SDS and REACH compliance docs for EU-origin shipments to avoid customs holds on toxic phenol derivatives
• Avoid bulk packaging over 25kg without stabilizers, as anti-dusting agents are allowed only if not rendering product use-specific (note g)

2-Aminophenol (o-Aminophenol)
2-Aminophenol is an amino-phenol with ortho-positioned amino and hydroxy groups on benzene, fitting HTS 2922.29 as an oxygen-function amino-compound with single oxygen function. Used primarily as a dye intermediate and in rubber antioxidants. Its structure excludes it from multi-oxygen function categories.
Metanilic Acid (3-Aminobenzenesulfonic Acid)
Though containing sulfonic acid, metanilic acid classifies here as an amino-phenol derivative not qualifying as sulfonated under exclusion notes, with primary oxygen amino-function. It's a key intermediate for azo dyes. Falls under 'other' amino-phenols per hierarchy.
p-Aminosalicylic Acid (PAS)
p-Aminosalicylic acid features amino and single phenolic hydroxy with additional carboxylic acid, but classifies as oxygen-function amino-compound under 2922.29 'other'. Used as anti-tuberculosis pharmaceutical intermediate. Single phenolic oxygen function distinguishes it.
2-Amino-4-chlorophenol
This halogenated amino-phenol contains chloro substituent but retains single oxygen function classification under 2922.29 per notes on halogenated derivatives. Used in pesticide and dye synthesis. 'Other' category captures such substituted phenols.
