Import Tips
• Submit FDA IND/NDA references and stability data; ensure benzoate salt form matches US pharmacopeia specs
• Label shipments clearly as 'API - Not for Direct Human Use' to avoid Chapter 30 finished product classification
• Verify chiral purity documentation as pyrazole derivatives often require specific stereoisomer certificates
