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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically enumerated like amino-hydroxy-naphthalenesulfonic acid
More specific subheadings within 2922.29 take precedence over .81.90 residual.
If containing sulfur directly linked to carbon (e.g., thiophenol derivative)
Organo-sulfur compounds shift to 2930 even if retaining amino-phenol structure (heading 2930 note).
If mixed with solvents for industrial cleaning beyond transport safety
Solutions rendered suitable for specific use exclude from Chapter 29 per note (e).

Import Tips & Compliance
• Label with GHS hazard pictograms (acute toxicity, skin corrosion) to meet DOT/IMDG transport regs for phenolic amines
• Provide CoA showing <0.1% nitro impurities to prevent reclassification under nitrated derivatives (chapter note)
• For solutions in water, ensure concentration <50% w/v as normal transport form per note (d); higher may imply specific use

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.
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.
N-(4-Aminophenyl)acetamide (p-Aminoacetanilide)
p-Aminoacetanilide is an N-acetylated amino-phenol ether equivalent, with single oxygen function in acetamido group classifying under 2922.29.81.90. Intermediate for paracetamol and dyes. Acetyl doesn't constitute additional oxygen function.
