  1. Hey @HarshitShah

    Goods/sectors that are out of the GST ambit include alcohol and specified petroleum products like petroleum crude, high-speed diesel, motor spirit, aviation turbine fuel and natural gas. Alcohol for human consumption continues to attract state excise duty and VAT. Tobacco and tobacco-based products attract both excise duty and GST. Taxes such as stamp duty, toll tax, road tax, electricity duty etc. are not part of GST.

    Hope this helps!

  2. Hey @HarishMehta
