Fuel tax (which is significantly larger than the profit made by those 'evil' oil companies), excise tax (on the vehicle), road use tax, social security and unemployment taxes on the driver every time the product or any of its ingredients are transported. We would also have to remember the 12% FET on the truck and trailer when sold new (something on the order of $200K, making a tax of approximately $24K) and taxes on the products and services used in maintenance being reflected as overhead costs in transportation, and this doesn't really have anything to do with the product, but the product is still carrying this cost.
Moving back to the product, you have sales tax at the counter and several layers of income tax and payroll taxes every time value is added or the product changes hands.
