Import Tips
• Verify purity and isocyanate content via certificate of analysis to confirm classification under 2929.10.80.10 and avoid misclassification as mixtures
• Include safety data sheets (SDS) documenting isocyanate hazards for DOT and EPA compliance during transport and handling
• Ensure proper stabilization packaging to prevent moisture reaction, a common pitfall leading to shipment rejection
