Import Tips
• Provide melting point (52-56°C) and assay documentation to distinguish from other anhydrides
• Ensure packaging prevents moisture absorption, as hydrolysis creates maleic acid (different HTS 2917.19)
• Declare CAS 108-31-6 and confirm not sulfonated/nitrated derivatives per Chapter notes
