Import Tips
• Obtain FDA Drug Master File (DMF) and ensure compliance with USP standards for purity and impurities
• Provide Certificate of Analysis (CoA) and stability data; common pitfall is inadequate microbial testing documentation
• Verify bulk API status vs finished dosage forms to avoid misclassification under Chapter 30
