Import Tips
• Submit FDA registration and drug listing numbers for the manufacturing facility to expedite clearance
• Include microbial limit testing results as sulfonamides are prone to contamination issues during import
• Avoid bulk packaging that suggests industrial use to maintain pharmaceutical classification
