The U.S. Postal Service has proposed a permanent 11% fuel surcharge alongside an average 5.9% increase in major domestic shipping rates. The changes would take effect on January 17, 2027, pending Postal Regulatory Commission review.
An existing charge would become permanent
USPS said in its November 12 announcement that the fuel surcharge would replace the temporary 8% transportation-related price increase. That measure began on April 26, 2026, and is scheduled to expire on January 17, 2027, the same day the replacement would begin.
The proposal raises the fuel-related percentage by three percentage points. USPS attributed the additional amount to a further increase in fuel prices and said the surcharge would be reevaluated in July 2027 using fuel prices from the first half of the year.
The surcharge and rate increase are separate
The domestic changes cover Priority Mail, Priority Mail Express, USPS Ground Advantage and Parcel Select. The Postal Service’s filing in docket CP2027-1 specifies that the fuel surcharge would be calculated as a percentage of base postage.
The 5.9% figure is an average price adjustment for those services, not a uniform increase for every package. Because the fuel surcharge replaces a transportation adjustment already in place, the two headline percentages don’t establish a single across-the-board increase over current shipping bills.
Weekly fuel pricing would come later
The filing calls for a flat 11% surcharge at the January launch. USPS says it intends to authorize changes for a weekly surcharge later in 2027, based on average fuel prices reported by the U.S. Energy Information Administration. The filing gives no specific launch date for that weekly mechanism.
The surcharge would be permanent, but its rate could change.
International shipping faces a different increase
USPS said the proposed fuel surcharge would not apply to international products at this time. A separate average price increase of 7.9% would cover Priority Mail Express International, Priority Mail International, First-Class Package International Service and International Priority Airmail.
The Postal Service is also adjusting international country rate groups and their assignments. The announced average therefore does not establish the exact increase for every international shipment.
Stamp prices would remain unchanged
The announcement leaves stamp prices and competitive Post Office Box prices unchanged in January. USPS filed the shipping changes on November 12 after approval by its Board of Governors, but regulatory review remains part of the process.
As of November 15, 2026, Postal Explorer still lists the January 2027 price files as proposed, with a November 12 revision date.
