DOE Diesel Price Band — How Southeastern's Surcharge Is Set
Southeastern Freight Lines publishes a schedule mapping ranges of the weekly DOE/EIA national average on-highway diesel price to a fuel surcharge percentage. When the EIA publishes a new diesel price (every Tuesday), the surcharge moves to the band containing that price.
| DOE Diesel Price Band | Current DOE Price | Surcharge |
|---|---|---|
| $5.63 – $5.66/gal | $5.652/gal | 45.2% |
This is the band currently in effect. The full band schedule is published by Southeastern Freight Lines; the API returns the matched band with every response.
The trigger variable is public: see the current diesel prices by state or pull the weekly index from the Diesel Price API.
