I WANTED TO KNOW WHAT WILL BE THE GST RATES ON REPACKED DRUGS UNDER FDA LICENCE. THIESE ARE SMALL PACKINGS OF BULK DRUGS USED AS MEDICAMENTS FOR HUMAN AND VETERINARY MEDICINE. CAN THEY BE CLASSIFIABLE UNDER HSN CODE 3004 OF CHAPTER 30. FOR EXAMPLES ITEMS LIKE BORIC ACID I.P., GLYCERINE I.P., MAGNESIUM SULPHATE I.P., IN SMALL PACKINGS INTEDED FOR MEDICINE GENERIC WITHOUT ANY BRAND NAME.
