Explaining the task structure, sources stated if expense of production of ATF is Rs 100 per kilolitre, the fuel at exit from the refinery will be priced at Rs 111 per kilolitre after imposing 11 per cent import tax duty. If the expense rises to Rs 110, the ex-refinery rate would draw in an import tax task of Rs 12. Petrol and diesel already attract specific excise duty for the very same purpose. Under the existing structure, both natural gas and ATF draw in the Centre’s excise task and a state’s value-added tax (VAT).
