Many shipping and delivery companies and freight carriers include a fuel-cost surcharge in their rates and invoices to cover the cost of diesel fuel.
We collect and publish retail diesel fuel price data, and many shippers and truckers use that information in their fuel-pricing formulas. We do not calculate, assess, or regulate diesel fuel surcharges, and we cannot tell transportation companies and freight carriers how to calculate a fuel surcharge.
Every company has its own method for calculating fuel surcharges. Many major transportation companies have information about how they calculate surcharges on their websites. We do not endorse or recommend any method for calculating fuel surcharges.
You can find weekly retail on-highway diesel fuel prices in our petroleum and other liquids data.
