Import Tips

• Obtain safety data sheets (SDS) and ensure proper Hazard Class 6.1 labeling for toxic liquid UN 2480 during transport

• Verify purity levels (>99%) via certificate of analysis to confirm classification as chemically defined compound under Chapter 29

• Avoid misclassification as polyurethane prepolymer; pure MDI must be imported without added polyols
