Import Tips
• Document stabilizer levels (<1%) to prove compliance with Chapter 29 note (f); excess renders it a mixture
• Provide stability study data showing necessity for transport; arbitrary additives trigger reclassification
• Coordinate with FDA on 'prior notice' filing specifying stabilized chemical identity
