Import Tips
• Include FTIR or HPLC certificate verifying ≥99% purity and CAS 537-98-4 to distinguish from esters or derivatives
• Label as 'food grade' or 'cosmetic grade' with heavy metal limits (<10ppm) per FDA import requirements
• Avoid retail packaging (>20kg drums preferred) to prevent classification as Chapter 32 coloring matter preparations
