2847.00.00.00Higher: 38.7% vs 6.5%

If incorrectly viewed solely as sodium salt without organic function

Chapter 29 note (C)(1) mandates classification with organic compound, not inorganic salts of Chapter 28.

Import Tips & Compliance

โ€ข Submit salt formation documentation showing equivalence to parent sulfonamide acid for proper 2935 classification

โ€ข Ensure pharmacopeial compliance (USP/EP) certification; common pitfall is classifying as Chapter 28 inorganic salt

โ€ข Declare exact purity percentage; impurities >2% may trigger reclassification as chemical mixture
