m-Aminophenol from China
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.

Import Tips
• 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
