Harmonised System of Nomenclature (HSN Codes) 2933 are used for the CARBOXYIMIDE-FUNCTION COMPOUNDS (INCLUDING SACCHARIN AND ITS SALTS) AND IMINE-FUNCTION COMPOUNDS 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.
