The reported price
Associated Press reported that the U.S. diesel average reached $5.85 a gallon on September 4 as the war with Iran disrupted fuel flows. The record is in current dollars; it should not be described as an inflation-adjusted record without a separate calculation. The national average also does not mean that every state or station charged the same amount.
How the pressure reaches other purchases
Diesel powers much of the equipment and transport used to move goods. AP highlighted perishable food, which requires repeated hauling and restocking, and reported that some businesses had added charges to orders and deliveries. The timing and extent of further price increases remained uncertain.
Read the actual charge
When comparing deliveries, include fuel surcharges and other fees in the total price. A business reviewing freight bills can check the surcharge’s benchmark, base price and update interval against its contract. Do not assume that a percentage increase in diesel will produce an identical percentage increase in a product’s price: fuel is only one component of the final cost.
