Import Tips
• Include technical data sheet proving use as diazonium coupler to distinguish from general amino-phenols
• Avoid anti-dusting agents that could render it suitable for specific non-dye uses, risking Chapter 29 note (g) exclusion
• For bulk imports, ensure packaging complies with DOT/UN hazardous material regulations for organic chemicals
