The next time you go to mail a package, be ready to pay up: The U.S. Postal Service's governing board approved temporary price increases for package shipping set to take effect in one month.

On Wednesday, the USPS confirmed it is adding 8% surcharges for Priority Mail services, Ground Advantage and Parcel Select shipping. The announcement comes as fuel costs are spiking, with the national average for diesel fuel — on which the agency's long-haul trucks run — at $5.38 per gallon, up from $3.76 a month ago, according to AAA.

The USPS described the surcharge as "a time-limited price change to better align its costs of transportation with the market." But, in a warning that's perhaps scarier for cost-conscious Americans, the announcement also acknowledged that the surcharge could be a "bridge to a permanent mechanism to reflect market conditions in prices."

Democratic officials immediately responded, calling out the growing consumer impacts from the Iran war — now in its fourth week — which has sent oil and gas prices soaring globally.

"Groceries. Gas. Now packages. Is there anything Donald Trump hasn't made more expensive?" Illinois Gov. JB Pritzker wrote on X. "Call it what it is: the Trump Mail Tax."

In its statement, the USPS defended the price increases, which still need final approval before implementation.

"Transportation costs have been increasing, and our competitors have reacted with a number of surcharges," the statement said. "This charge is less than one-third of what our competitors charge for fuel alone, so even with this change, the Postal Service continues to offer great value."

FedEx and UPS have long charged fuel surcharges, and those surcharges have increased significantly since the Iran war began, according to the Wall Street Journal.

The USPS chose to hold stamp prices at 78 cents in January. It did, however, hike other postage and shipping rates that month, including price increases of 5.1% to 7.8% for the services that were just hit with the additional 8% surcharge (Priority Mail, Priority Mail Express, USPS Ground Advantage and Parcel Select).

Before the recent fuel price spikes, the USPS had pointed to challenges including rising labor costs, coupled with long-term funding deficits.

The agency has said higher prices are necessary to restore financial stability. If approved by the Postal Regulatory Commission, the new surcharge for package shipping will be in effect from April 26 to Jan. 17.
