Harmonised System of Nomenclature (HSN Codes) 3914 are used for the ION–EXCHANGERS BASED ON POLYMERS OF HEADINGS 3901 TO 3913, IN PRIMARY FORMS products under Goods and Service Tax classification.
India was originally using 6 digit HSN codes to classify commodities but later two more digits were added to make the codes more precise, resulting in an 8 digit classification.
