Find BIS requirements by HSN code

HSN stands for Harmonised System of Nomenclature. It's the 8-digit code India uses to classify products for customs and tax. BIS maps many HSN codes to mandatory certification, so your HSN tells you straight away whether your product needs BIS and which scheme applies.

Search this page by HSN code or product name. Each result shows whether BIS is mandatory, the certification type (CRS or ISI), the applicable Indian Standard, and an estimated cost. If you don't know your HSN, our free checker maps your product to the right code.

Yes, and it's common. One HSN can cover several products, each with its own standard and certification type. For example, HSN 8504 covers both mobile chargers (CRS) and power adapters (CRS); under the same heading, oil-immersed distribution transformers (IS 1180 Part 1) need the ISI Standard Mark. Always check the specific product, not just the code.

HSN is a classification code for customs and tax, while an IS standard is a specific quality and safety specification from BIS. Your HSN tells you which product category you're in; the IS standard tells you the exact requirements you need to meet.
