Import Tips
• Disclose encapsulation matrix composition; if >20% coating, risks reclassification as prepared product
• FDA requires proof that microencapsulation doesn't alter chemical identity for Chapter 29 retention
• Use tamper-evident, moisture-proof drums; agglomeration during transit common pitfall
