Import Tips
• Verify purity certificate (typically >99%) to confirm classification as chemically defined compound under Chapter 29
• Include Material Safety Data Sheet (MSDS) showing proper UN 2215 shipping name for DOT compliance
• Avoid misclassification as polymer precursor; pure maleic anhydride excludes heading 3900 series
