Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as an aniline derivative salt
Some amino-phenol salts may align with amino-function compounds if oxygen function is secondary.
If imported as a diluted chemical preparation
Solutions beyond allowed solvents (per chapter note 2(e)) become chemical preparations in Chapter 38.
If containing a heterocyclic ring structure
Cyclized derivatives with oxygen/nitrogen heteroatoms shift to heterocyclic compounds heading.

Import Tips & Compliance
• Provide salt formation documentation and molecular structure to distinguish from base compound under Chapter 29 salt rules
• Ensure proper labeling of CAS number (51-78-5 for base) and concentration to avoid reclassification as a mixture
• Check for anti-dumping duties on specific amino-phenol salts; declare country of origin accurately
