Import Tips & Compliance
• Provide Certificate of Analysis (CoA) and pharmacopoeial compliance certificates to verify purity and USP standards during customs clearance
• Ensure DEA registration if intended for controlled substance production, as Clobazam precursors may trigger scrutiny
• Label shipments clearly as 'pharmaceutical intermediate - not for direct human consumption' to avoid FDA consumer product classification
