Import Tips
• Provide FDA Drug Master File (DMF) and Certificate of Analysis confirming USP purity and anti-infective pharmacological action
• Include detailed chemical structure documentation to verify sulfonamide classification under Chapter 29 notes
• Avoid misclassification as finished dosage forms; ensure import as bulk API only to prevent Chapter 30 reclassification
