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
