Import Tips
• Obtain DEA registration if importing for any controlled substance-related research, as ethinamate has sedative properties
• Provide Certificate of Analysis (CoA) confirming 99%+ purity and INN identity to avoid reclassification as mixtures
• Declare as 'pure chemical reference standard' to prevent scrutiny under pharmaceutical finished dosage forms
