Import Tips
• Provide Certificate of Analysis (COA) confirming 99% purity and maleic acid composition to verify classification under 2917.19.23.00
• Ensure proper hazardous material declaration (UN 2215) and UN-approved packaging for transoceanic shipment
• Avoid misclassification as fumaric acid (2917.19.1500) by confirming cis-isomer structure via spectroscopic data
