USPS plans a weekly parcel fuel surcharge

USPS plans to introduce a weekly parcel fuel surcharge in January 2027, according to Supply Chain Dive’s October 26 report. The publication describes a percentage of base postage linked to diesel and jet-fuel prices, covering domestic Ground Advantage, Priority Mail, Priority Mail Express and Parcel Select shipments. Negotiated contracts may carry customized terms. [2]

BTO located the official PostalPro FAQ listing but could not retrieve the full FAQ; its destination returned an access error and, during a browser follow-up, Page Not Found. The implementation details here therefore remain attributed to Supply Chain Dive, rather than independently verified from the full USPS document. [1] [3]

Supply Chain Dive reports that diesel-based percentages will be published three to five days before taking effect, and jet-fuel percentages three to four days before. It says shippers will receive current and upcoming percentages with effective dates electronically, including through APIs or other means, and that historical data will be public. BTO has not confirmed those mechanics from the inaccessible full FAQ. [2]

There is an earlier pricing decision behind this development. On March 25, USPS announced a proposed temporary 8% increase to base postage for the same four domestic package products, describing it as a bridge to a permanent transportation-cost mechanism. That announcement set out a proposed April 26 start and January 17, 2027 end, subject to Postal Regulatory Commission review. It excluded First-Class stamps. Those earlier proposed dates do not establish the precise start of the new weekly surcharge. [4]
