How diesel prices are set in Tamil Nadu
The price at the pump adds up the oil company's base price, freight, the central excise duty, the dealer's commission and Tamil Nadu's VAT. VAT is charged last, on everything before it, so when crude prices rise the state's tax take rises too. Districts far from a depot pay more for freight, which is why prices differ within Tamil Nadu.
