Record diesel prices are rewriting the maths of every inland move. The US national average has climbed past $6.50 a gallon, and European diesel has reached its highest level since 2005. For freight forwarders, the effect lands first on the short legs: the truck that collects a container at the port and the road leg that completes the journey. Drayage costs deserve a fresh look now, because a quote built on last quarter’s fuel price no longer covers this quarter’s reality. This guide explains how diesel flows into trucking rates, where quotes carry the most exposure, and how to price inland freight with confidence.
Why Diesel Reaches Every Inland Quote
The latest DOE/EIA data puts the US national average diesel price at a record $6.529 a gallon, up more than $1.90 since early July. Before the war with Iran began in late February, the average sat near $3.76. Most tanker traffic is bottlenecked in the Strait of Hormuz, and crude prices have climbed with the disruption. Europe feels the same pressure, with diesel at its highest level since 2005. Fuel is the one cost every trucker pays, so a move of this size travels through the whole inland network: port drayage, rail ramps, warehouse transfers and final delivery.
How Diesel Prices Push Up Drayage Costs
Most truckload, LTL and parcel carriers use surcharge formulas tied to the DOE/EIA national diesel average, so surcharges rise automatically as diesel climbs. The usual method takes the current diesel price, subtracts a contract base price, and divides by an assumed fuel economy of roughly 6.0 to 6.5 miles per gallon, recalculated each week from the Monday EIA figure. The outcome is a per-mile fee that steps up with the pump price.
Container drayage adds a wrinkle. Short port runs spend a large share of their time in terminal queues, repositioning chassis and returning empty. One large trucking carrier reports recovering only about 80% of its fuel costs through surcharges, with idle time, out-of-route miles and deadhead trips accounting for the gap. Those unrecovered costs help explain why drayage costs can rise faster than a simple per-mile formula suggests.
Contract Rates and Spot Rates Carry Fuel Differently
Where fuel sits inside a quote depends on how the freight is bought. Contract carriers with proper fuel surcharge clauses are largely insulated, because the surcharge moves with the index. Spot freight behaves differently. It often carries no separate surcharge line, with fuel baked into the all-in rate, so the carrier absorbs a mid-week diesel move until the next load books.
That leaves smaller carriers working the spot market with less ability to recover higher fuel costs, and the president of the Intermodal Association of North America has noted that some owner-operators are shutting down. Drayage capacity is already tight. Forwarders buying on the spot market should expect drayage costs to shift with the weekly diesel reading and should allow for the possibility that fewer trucks are available at the quoted price.
Two Quotes, Two Exposures
These are illustrative cargo scenarios.
Consumer electronics, Los Angeles to a warehouse in Ontario, California. A forwarder quoted a flat drayage price in June, valid for 60 days. The route is short, but the truck’s day includes a terminal queue and a chassis return. With diesel up more than $1.90 a gallon since early July, the carrier’s cost now sits above that flat price. The forwarder who built in a fuel adjustment passes the change through transparently. The one with a fixed quote carries the gap, or faces a carrier who declines the load.
Automotive parts, Savannah to a plant 250 miles inland. The shipper has two options: a direct truck move or intermodal rail. With diesel above $6, shippers are increasingly weighing intermodal as an alternative to highway freight. A forwarder who presents both options, with transit times and fuel exposure side by side, gives the customer a real choice and keeps the business.
How to Build Diesel Into Your Inland Quotes
Clear structure protects margins and keeps drayage costs transparent for your shippers. These steps help:
- Separate base rate and fuel. Show the base rate and a diesel surcharge indexed to the weekly EIA average, so the shipper sees exactly what moves and why.
- State the base price and review cycle. Name the base diesel price in the quote and confirm the surcharge updates weekly, in line with the index.
- Shorten quote validity. A seven to fourteen day window suits a market that shifts weekly. Add wording that makes the quote subject to fuel adjustment.
- Define waiting time. Agree free time at terminals and set clear charges beyond it, since idle hours are part of what carriers struggle to recover.
- Offer alternatives. Present intermodal, rail ramps or consolidated moves where the lane suits them.
- Explain the index. One short paragraph on how the surcharge works builds trust and prevents disputes at invoice time.
What to Watch Next
Diesel is likely to stay elevated while the conflict in the Middle East continues. A well-built surcharge works in both directions, falling as the index falls, which treats shippers fairly and keeps the relationship strong when prices ease. The forwarders who communicate early and index openly will keep their customers through the volatility. Treat every inland quote as a live document in this market. Review it weekly, explain it clearly, and keep alternatives ready.
