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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ester is saturated acyclic carboxylic ester without amino priority
If amino function not principal, classifies as general ester; but Chapter notes prioritize oxygen-function amino-compounds.
If for carboxamide derivatives rather than esters
Different oxygen functions like amides fall under later 2924 headings per numerical order.
If dissolved in solvents for specific industrial application
Solutions for specific use (not safety/transport) exclude from Chapter 29 per note (e).

Import Tips & Compliance
• Specify 'ester of p-aminophenol' in entry docs to invoke Chapter 29 ester/salt rules staying with phenolic parent
• Provide esterification degree via spectroscopy to confirm not hydrolyzed back to free phenol
Related Products 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.
