Harmonised System of Nomenclature (HSN Codes) 8440 are used for the BOOK-BINDING MACHINERY, INCLUDING BOOK-SEWING MACHINES 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.
