Import Tips
• Obtain FDA approval and Drug Master File (DMF) prior to import; antivirals require strict quality control documentation
• Verify Certificate of Analysis (CoA) for purity and stability; common pitfall is inadequate stability data for bulk APIs
• Declare exact composition to avoid reclassification; use bulk containers to confirm non-retail status
