Notes from the source
Matrix footnote #2 (MISSISSIPPI): LNG is taxed per Diesel Gallon Equivalent beginning July 1, 2015. The tax rate was set by the 2014 Legislative Session to be taxed at $.18 per Diesel Gallon Equivalent. A Diesel Gallon Equivalent of LNG is measured at 6.06 lbs. CNG is sold to consumers on the Gasoline Gallon Equivalent of 5.660 lbs. However, the tax rate is still on the measurement of $.18 cents per hundred cubic foot. The above tax rate converts CCF to GGE.

On an IFTA return, a higher rate doesn't mean you pay more overall. Fuel you buy in a high-rate state earns a bigger credit. What matters is where you burn the fuel versus where you buy it.
