HSN - Harmonized System of Nomenclature
HSN (Harmonized System of Nomenclature) is an internationally standardized system of names and numbers to classify goods for customs and tax purposes. In India, the HSN code is used to identify goods for GST (Goods and Services Tax) registration and filing. The HSN code helps simplify the tax system by categorizing products under specific codes. Businesses are required to mention the HSN code on invoices based on the turnover and type of goods. The HSN system ensures consistency in the classification of goods, making it easier for businesses and tax authorities to track and apply taxes efficiently.
