Import Tips
• Specify flake size (typically 6-20 mesh) and bulk density (0.8-1.0 g/cm³) in commercial invoice for proper handling instructions
• Use vented steel drums with moisture-absorbing agents to prevent caking during ocean transit
• Conduct melting point test (130-140°C) upon arrival to verify no fumaric acid contamination
