Import Tips
• Require Certificate of Analysis (CoA) confirming USP purity and identity as acriflavine to match HTS 2933.99.4200 classification
• Ensure FDA prior notice filing and compliance with drug import regulations; bulk powder typically requires drug master file
• Verify no contaminants that could reclassify as mixtures under Chapter 38; maintain 99%+ purity documentation
