Import Tips
• Verify FDA registration and provide Certificate of Analysis (CoA) confirming API purity and stability
• Ensure labeling complies with 21 CFR 201 for prescription drugs, including lot number and expiry date
• Avoid misclassification by confirming sulfonamide content; common pitfall is bulk powder import under 2935
