Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a mixture with phenol impurities exceeding 1%
Mixtures of phenols not purely nitrated derivatives fall under general phenols heading per Chapter 29 notes.
If when imported as sodium salt (sodium p-nitrophenolate)
Inorganic salts of organic compounds classified with the organic base per Chapter Note 3(C)(1).
If dissolved in water or solvent for safe transport
Solutions only classifiable here if normal for safety/transport per Chapter Note (e), otherwise mixtures.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming 99%+ purity and para isomer content to avoid reclassification
• Include Safety Data Sheets (SDS) documenting hazards (toxic, irritant) for proper hazmat shipping compliance
• Verify packaging meets UN standards for toxic solids; common pitfall is insufficient stabilization against decomposition
