Import Tips
• Include DMF (Drug Master File) reference if destined for pharma; FDA requires advance notice via Prior Notice system
• Microbial limits testing (<1000 CFU/g) essential; common cause of pharma import refusals
• Separate from food shipments to avoid cross-contamination concerns during customs inspection
