p-Aminophenol Acetate Ester from Canada
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.

Import Tips
• 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
