The Central Board of Indirect Taxes and Customs (CBIC) has made it mandatory to mention the 8-digit HSN code in tax invoices for 49 chemical-based products.
The move is expected to reduce tax evasion.
HSN or Harmonized System of Nomenclature code is a system for classification of goods across the world.
The code is called the universal economic language for goods.
It was developed by the World Customs Organization.
