HSN codes and GST: a guide for chemical buyers
How HSN codes and GST work on chemical purchases in India, and why the right HSN on your invoice matters.
Every GST invoice for chemicals must show the correct HSN (Harmonised System of Nomenclature) code and GST rate. Getting it right keeps your input-tax credit clean and your e-way bills valid.
Why HSN matters
- Determines the correct GST rate for the product.
- Required on tax invoices and e-way bills for inter-state movement.
- Standardises classification for customs and compliance.
Common chemical HSN ranges
| Group | HSN | Typical GST |
|---|---|---|
| Inorganic acids & oxides | 2806 / 2807 / 2811 | 18% |
| Inorganic salts | 2827 / 2833 / 2836 | 18% |
| Organic solvents | 2914 / 2905 / 2902 / 2915 | 18% |
| Surfactants & preparations | 3402 | 18% |
| Lab reagents & fine chemicals | 3822 / 2942 | 12-18% |
