Import Tips
• Include HPLC or GC analysis confirming >98% monomeric 4,4'-MDI content for accurate HTS verification
• Label containers with UN 2489 hazard class and ensure respiratory protection guidelines in import docs
• Avoid bulk shipments without temperature control, as monomeric MDI has lower stability than polymeric forms
