Import Tips & Compliance
• Include USP/EP certificates and DMF references; FDA may require pre-import notification for pharma intermediates
• Use low-humidity packaging; common issue is clumping reclassified as not purely solid
• Avoid co-mingling with organics to prevent Chapter 29 reclassification
