Fuel marking and monitoring have curbed adulteration

Fuel adulteration involves the introduction of kerosene into petrol or diesel with the resultant mixtures sold to consumers as pure petrol or diesel respectively. Dumping on the other hand, involves the diversion of duty-exempt export fuel for illegal sale in the local market.

These malpractices are mainly carried out to take advantage of the price differential between domestic kerosene and petrol and diesel, particularly before the introduction of the anti-adulteration levy, and the zero-rated export bound petroleum fuels by selling the same as taxed local product.
