Import Tips
• Submit salt formation documentation showing equivalence to parent sulfonamide acid for proper 2935 classification
• Ensure pharmacopeial compliance (USP/EP) certification; common pitfall is classifying as Chapter 28 inorganic salt
• Declare exact purity percentage; impurities >2% may trigger reclassification as chemical mixture
