Record Diesel Prices: How Ecommerce Shippers Should Handle Fuel Surcharges
Diesel is above $6 a gallon and carriers are passing it through. Here is how surcharge tables work and how to protect your 2027 shipping budget.

Record diesel prices flow straight into your shipping bill through fuel surcharges. The U.S. on-highway average reached $6.276 a gallon on October 19, 2026, up about 10 cents in a week. Carriers apply surcharges as a percentage of freight charges, so every dollar of diesel increase raises the cost of each parcel and pallet you ship.
Laneage covers freight, supply chain and ecommerce operations. This guide is for ecommerce brands and small shippers that pay carrier invoices and set shipping prices. It explains why diesel is high, how surcharge tables work, and what to do before 2027 rate quotes arrive.
Why Are Diesel Prices at Record Highs?
Diesel is at record highs because the world has lost refining capacity at the same time demand is strong. Energy advisor Tom Kloza told FreightWaves in mid-September that the world has shed about 7 million barrels a day of refining capacity, mostly in Russia and the Persian Gulf.
A Saudi East-West pipeline closure added to the squeeze. It feeds refineries with about 1.8 million barrels a day of capacity. Kloza also warned that Northeast heating demand would press distillate supplies as temperatures fall.
The U.S. Energy Information Administration (EIA) shows the result. Its weekly on-highway diesel price stood at $6.276 on October 19, up $0.097 from the prior week. Kloza said at the time that prices could keep climbing over the next 100 days.
Is Diesel Rising Faster Than Crude Oil?
Yes, diesel is rising faster than crude. The C.H. Robinson October market report said diesel prices are climbing faster than crude because of refinery outages, strong export demand and global supply bottlenecks. That gap is why a barrel of oil can look calm while your surcharge keeps rising.
Kloza put numbers on it. At a normal relationship between crude and diesel, he said, crude would trade near $175 a barrel given where diesel sits today. The refined product is expensive, not just the raw material.
There is also talk of a federal diesel export ban. The same C.H. Robinson report noted that none has been announced. Most analysts see a ban as risky policy, so do not plan your budget around one.
How Do Fuel Surcharges Actually Work?
A fuel surcharge is a percentage added to your base freight or parcel rate that moves with the diesel price. Carriers publish a table that links ranges of the national diesel average to a surcharge percentage. When diesel moves up a band, your surcharge steps up with it.
The surcharge is calculated on the freight charge, so it also grows when your base rate grows. A carrier that lifts its base rate 5% and sees diesel climb is raising your bill twice. Many shippers watch the base rate and forget the table.
Here is a simple illustration with made-up numbers. Suppose a pallet costs $200 to ship and the surcharge is 30%. You pay $260. If diesel pushes the surcharge to 36%, the same pallet costs $272, a 4.6% increase with no change to the base rate.
| Item | Base rate | Surcharge % | Total |
|---|---|---|---|
| Before diesel jump | $200 | 30% | $260 |
| After diesel jump | $200 | 36% | $272 |
| Base rate +5% too | $210 | 36% | $285.60 |
What Should You Check in Your Carrier Agreements?
Start with the surcharge table itself. Read how often it updates, which index it uses and where the bands begin. A table that starts counting at a low diesel price charges you more at every level than one that starts higher.
The checklist below covers the terms that matter most.
- Confirm the index and publication day the carrier uses, such as the EIA weekly average.
- Check the starting diesel price where surcharges begin.
- Ask whether the surcharge applies to accessorial charges as well.
- Find out whether the table can be changed mid-contract with notice.
- Compare tables across carriers, not just base rates.
Our earlier piece on diesel prices and freight costs covers how earlier price swings reached shippers. The basic lesson holds: a lower base rate with a harsh table can cost more than a higher base rate with a fair one. Run your last three months of shipments through both before you sign.
Which Shipments Feel Diesel the Most?
Heavy, long-haul and temperature-controlled freight feels diesel the most because fuel is a larger share of the cost per load. Parcel shippers feel it too, but their surcharges are published by the carrier and changed on a schedule rather than weekly.
Refrigerated loads carry an extra layer because the trailer's cooling unit burns diesel. If you ship perishables, see our guide to booking temperature-controlled loads for how fuel fits into reefer pricing.
Light, dense parcels shipped short distances are the least exposed. If your products fit that profile, a regional carrier may offer a cleaner surcharge than a national one. We see this pattern often among small brands that ship from a single warehouse.
Why Does the Surcharge Lag the Pump Price?
Surcharge tables update on a delay, so the number on your invoice trails the price drivers see at the pump. Most carriers key off a weekly national average. That means a spike in diesel can take one to two billing cycles to show up in full.
The lag works in both directions. When prices fall, your surcharge keeps reflecting the higher week for a while. Kloza also noted that truck-stop fuel margins rose from about $0.04 a gallon to about $0.07, and that retail prices usually run about $0.40 a gallon over cost. Catch-up pricing at the pump was still expected.
For a shipper, the lesson is timing. Do not wait for the invoice to confirm what the market already showed. If diesel moves a quarter or more in a month, assume your surcharge will follow and adjust your cash forecast now.
What Mistakes Do Shippers Make With Fuel Costs?
The most common mistake is negotiating only the base rate. A carrier can give you a headline discount and recover it through a surcharge table that starts low. Always compare the all-in cost on a sample of real shipments.
A second mistake is ignoring accessorials. Residential delivery, liftgate service and delivery area surcharges often carry their own fuel percentage. Those small fees multiply quickly on a busy week.
A third mistake is passing every cost increase to customers at once. Shoppers abandon carts when the shipping line jumps. Spread changes across order minimums, flat-rate tiers and delivery options instead of one large hike.
How Do You Budget for 2027 When Diesel Is This High?
Build your 2027 budget on current diesel, with a scenario above it. Kloza said $3 diesel is likely behind us for at least 15 to 16 months. A plan that assumes prices fall back soon is a plan that will miss.
The C.H. Robinson report advised shippers to plan for 2027 quotes with this fuel cost in mind. Use three scenarios and write down what you would do in each.
- Base case: diesel stays near $6.25 and surcharges stay where they are.
- High case: diesel rises another 10% over the winter.
- Relief case: prices ease in spring as refinery capacity returns.
For each case, translate the change into dollars per order. That number tells you whether to adjust shipping prices, set a free-shipping threshold or switch service levels. Peak season adds its own charges on top, so also review the 2026 holiday peak surcharge schedule.
What Can Ecommerce Brands Do Right Now?
You have more control than it feels like. Right-size your packaging, because dimensional weight and surcharges both scale with box size. Consolidate shipments where speed allows, and shift lighter orders to ground rather than express.
Review zone mix as well. If a large share of orders travels to far zones, a second fulfillment location can cut both distance and fuel exposure. Our guide to multi-warehouse fulfillment explains the trade-offs.
At Laneage, our editors advise brands to pass surcharges through transparently rather than bury them. A clear shipping fee preserves trust better than a surprise price change at checkout. Test the message on a small segment before rolling it out.
One more habit helps. Keep a simple monthly log of your fuel line as a percentage of total freight spend. When that share climbs two months in a row, you have the evidence you need to reopen a rate conversation. Carriers respond to data far better than to general complaints about cost.
Conclusion
Record diesel prices will keep showing up in carrier invoices through the winter. The surcharge table, not the headline rate, decides how much of that you pay. Treat it as a negotiating item and budget with scenarios.
Next step: export your last 90 days of carrier invoices, separate the fuel line, and compare it with the carrier's published table. If the numbers do not match, raise it with your account rep this week.
