Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel.
Each jurisdiction determines which types of fuel are considered special fuels, and sets the tax rate for each type of special fuel. In New Mexico, diesel is the only type of fuel considered as a special fuel to be reported on IFTA returns. However in Texas, gasoline and diesel are special fuels and both types are reported on IFTA returns.
