Private-carrier fuel surcharges (through 2026)
FedEx and UPS have long levied fuel fees calculated as a percentage of base postage and updated as diesel and jet fuel prices move. When the Iran war and Strait of Hormuz disruptions pushed fuel costs up in 2026, those fees added to already elevated delivery prices for shippers.
Shippers came to expect fuel as a separately stated, frequently changing line item rather than part of the base rate.
Weekly indexed surcharges became the standard pricing structure in the parcel industry.
USPS is adopting the same structure, which is why the January rate is described as a bridge to a mechanism rather than a one-time increase.
