EIA does not calculate, assess, or regulate diesel fuel surcharges.
Fuel surcharges are negotiated privately by shippers and by transportation companies.
Each company may have its own method for calculating surcharges. Many major transportation carriers have information on their websites concerning their surcharge methodology. EIA does not endorse a particular method. You can perform an Internet search on fuel surcharges for more information.
EIA collects and publishes weekly retail diesel fuel price data. Many shippers, transportation companies, and truckers use that weekly retail price information in their fuel pricing formulas.
