Import Tips
• Specify flake size and melting point range (132-135°C) in commercial invoice to distinguish from powder form
• Include bulk density certification (0.6-0.8 g/cm³) as customs may verify physical specifications
• Declare exact assay percentage; flakes below 98% purity risk reclassification as mixtures
