Diesel: weekly EIA national average
The U.S. on-highway diesel index averaged $5.14/gal in June 2026, a down 7.8% change from May's $5.57/gal — and up 0.0% year over year.
Weekly EIA on-highway national diesel price · weeks ending Jun 7 – Jul 5, 2026
Diesel softened steadily through the month. The week-ending high was $5.35 and the low was $4.83 — a swing of 0.52 per gallon. For shippers tracking line-haul fuel exposure, that's roughly $3 in saved fuel cost per 1,000-mile dry-van trip versus the start of the month (assuming 6.5 mpg).
Fuel surcharges: parcel and LTL
Carriers reset fuel surcharges weekly off the EIA index. Below is the monthly average effective surcharge on each carrier's published table, plus an LTL composite drawn from the major carriers' national tariffs.
| Carrier / Mode | Jun 2026 avg | Prior month | Change |
|---|---|---|---|
| UPS Ground (parcel) | 24.00% | 24.00% | ▼ 0.00 pts |
| FedEx Ground (parcel) | 24.50% | 24.50% | ▼ 0.00 pts |
| LTL composite (dry) | 43.9% | 46.9% | ▼ 2.9 pts |
| Reefer LTL composite | 50.4% | 53.4% | ▼ 2.9 pts |
| Reefer FTL spot ($/mi) | $0.72 | $0.80 | ▼ $0.08 |
LTL composite reflects the simple average of Old Dominion, XPO, Saia, and Estes published national tables applied to the month's diesel average.
Canada–US passenger-lane border waits
Correction, 1 September 2026: the border wait figures in this issue reflect passenger lane readings, not commercial truck lanes, due to a parser defect in our data collection. The methodology note below incorrectly describes them as commercial-truck readings. The defect is fixed as of this date and figures from September 2026 onward are commercial. Diesel prices and fuel surcharge figures in this issue are unaffected.
Network-wide passenger-lane wait time averaged 2 minutes across the CBSA reporting crossings — up 0 minutes from the previous month. The three busiest GTA-corridor and BC crossings:

From the CargoTools desk
June 2026 brought steady relief on diesel. The EIA national average fell to $5.14, down 7.8% from $5.57 in May, and the weekly price dropped every week, from $5.35 in the week ending June 7 to $4.832 in the week ending June 28. Parcel surcharges did not move: UPS held at 24.00% and FedEx at 24.50%, the same as in May. The freight composites did follow diesel down. The LTL dry-van composite went from 46.9% to 43.9%, the reefer LTL composite from 53.4% to 50.4%, and reefer truckload fuel from $0.80 to $0.72 per loaded mile. Border waits held at a 2-minute network average. Huntingdon / Sumas and Pacific Highway led at 5 minutes each, and Lacolle / Champlain rose from 1 to 3 minutes. These are passenger-lane readings, as the correction note above explains. For parcel shippers, June fuel surcharges matched May; for LTL and reefer shippers, they were lower.

What this means for your shipping costs
- → Parcel: Parcel fuel surcharges held flat versus last month. No material change in your line-item exposure.
- → LTL: On a $400 LTL line-haul, fuel surcharge ran roughly $11.60 lower per shipment than last month. Use our FSC auditor to confirm your carrier passed the savings through.
- → Cross-border: Border waits held roughly steady. Check our live Border Wait Times dashboard before dispatch.

Methodology & sources
Diesel prices reflect the EIA's published U.S. weekly on-highway average aggregated across daily snapshots taken during the month. Parcel fuel surcharge percentages are computed using each carrier's published indexed-rate table applied to that day's diesel price, then averaged. LTL fuel surcharge reflects an industry composite of major national carriers (Old Dominion, XPO, Saia, Estes) regressed against diesel. Border wait times in this issue are the daily PASSENGER-lane reading sourced from CBSA, averaged across the covered month — see the correction in the border section above.
