Import Tips

• Verify EPA compliance under the Montreal Protocol as HCFC-123 imports are restricted and phased out; obtain necessary allocations or exemptions

• Provide detailed purity certificates (typically >99.9%) and safety data sheets confirming chemical identity to avoid misclassification

• Label containers with UN 1029 hazmat markings and ensure proper documentation for transport under DOT regulations
