Import Tips

• Provide technical data sheets proving diazonium salt composition for proper Chapter 29 classification

• Check for stabilizer content; excess additives may shift to heading 3824 chemical preparations

• Label shipments with UN numbers if hazardous; fast color bases often require dangerous goods declaration
