How carrier fuel surcharges work
LTL carriers add a fuel surcharge to every shipment as a percentage of the base freight rate. The percentage is determined by the carrier's fuel surcharge table, which maps the current U.S. Department of Energy (DOE) National Average Diesel Fuel Price to a surcharge rate. Each carrier maintains its own table with different thresholds and increments.
The surcharge is recalculated weekly when the DOE publishes updated diesel prices. As diesel rises, the surcharge percentage increases. As diesel falls, the surcharge decreases — but it never reaches zero. The result is a variable cost added on top of your negotiated base rate that changes every week.
Why fuel surcharges are unpredictable
Because fuel surcharge tables differ by carrier, the same DOE diesel price produces different surcharge percentages depending on which carrier handles your freight. A shipment quoted at $500 base rate might carry a 28% surcharge with one carrier and a 34% surcharge with another — a difference of $30 on a single invoice.
Weekly updates mean the surcharge on your invoice may not match the surcharge at the time you booked. If diesel prices spike between booking and delivery, your final cost increases with no warning. This makes it difficult to forecast freight spend or compare carrier quotes on an apples-to-apples basis.
Warp eliminates fuel surcharges entirely
Warp does not charge fuel surcharges. Every Warp quote is all-inclusive per-pallet pricing — the rate you see is the rate you pay. There are no fuel surcharges, no accessorial fees, and no terminal handling charges added after the fact. Your freight cost is locked in at booking and does not change based on weekly diesel price fluctuations.
Fuel surcharge FAQ
What is a fuel surcharge in freight shipping?
A fuel surcharge is an additional fee carriers add to your freight invoice to offset fluctuating diesel fuel costs. It is calculated as a percentage of the base freight rate, and the percentage varies by carrier and current DOE diesel price. Most LTL carriers update their fuel surcharge tables weekly based on the U.S. Department of Energy National Average Diesel Fuel Price.
How is the fuel surcharge percentage calculated?
Each carrier sets a base fuel surcharge percentage tied to a DOE diesel price threshold. As diesel prices rise above that threshold, the surcharge percentage increases incrementally. For example, a carrier might add 0.5% for every $0.05 increase above their base DOE price. The surcharge is then applied as a percentage of your base freight rate.
Does Warp charge a fuel surcharge?
No. Warp offers all-inclusive per-pallet pricing with no fuel surcharges, no accessorial fees, and no terminal handling charges. The rate you see is the rate you pay.
