Import Tips
• Obtain FDA Drug Master File (DMF) and ensure API meets cGMP standards with full impurity profile documentation
• Provide Certificate of Analysis (CoA) confirming pyrazole structure and pharmacological purity above 99%
• Avoid misclassification as finished dosage forms; declare as bulk API to prevent higher Chapter 30 duties
