GST for Inorganic chemicals in India

Goods and Service Tax (GST) rate tariff in India is designed in 6 categories of goods and services.  Four main GST rate slabs framed with Essential goods and services, Standard goods and services and luxury goods and services with 5%, 12%, 18% and 28% respectively.  Commonly used Goods and Services at 5%, Standard Goods and Services fall under 1st slab at 12%, Standard Goods and Services fall under 2nd Slab at 18% and Special category of Goods and Services including luxury - 28%.   The most essential goods and services attract nil rate of GST under Exempted Categories.     Luxury goods and services and certain specific goods and services   attract additional cess than 28% GST.
