Import Tips
• Provide USP CoA and DMF if used in drug formulations; FDA may require additional registration
• Segregate pharma-grade shipments to avoid cross-contamination claims during customs examination
• Higher duties possible if misdeclared; always reference specific HTS 2933.79.20.00 enumeration
