The U.S. Postal Service is seeking to temporarily place a fee on packages due to rising fuel prices as the war in Iran continues to rattle energy markets. 

The 8% fuel surcharge on packages under Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select is expected to take effect on April 26 and remain in place until Jan. 17, 2027. The Postal Regulatory Commission must review and approve the fee before it is enacted. If approved, first-class stamps and other mail services would not be affected.
