USPS July 2026 Competitive Rate Changes Target Bulky, Lightweight Packages
USPS Competitive rates are changing in July, with new lower dimensional weight divisor tilting impact toward light but large shipments.
Here's what's set to change on July 12:
Ground Advantage prices will mostly remain unchanged but USPS will be doing away with ounce-based rate differentiation for published Commercial USPS Ground Advantage prices.
However, announcement said this change would not effects customers with negotiated commercial rates for USPS Ground Advantage. That could mean sellers who purchase labels through marketplaces like eBay and Etsy will not be impacted but it's best to check with your specific label provider to be sure.
USPS will also be lowering the dimensional weight (DIM weight) divisor from 166 to 139 across all domestic competitive products, making larger light weight items more expensive to ship.
Making more money on larger packages (or conversely disincentivizing shippers from using USPS for larger packages) is clearly a new focus for USPS with a new rule that will also go into effect July 12, requiring accurate length, width, and height on all manifested parcels shipped via Parcel Select, USPS Ground Advantage, Priority Mail, and Priority Mail Express - and punitive non-compliance fees coming in 2027.
New fees: New Hazardous Materials fees will apply to Priority Mail Express, Priority Mail, Parcel Select, and USPS Ground Advantage.
Additional fee changes:
- Post Office Box prices will increase 3% on average, within the existing price ranges.
- Parcel Select price for forwarding and returns will increase from $3.80 to $6.
- Address Correction Service (ACS) with Shipper Paid Forwarding/Return will increase from $3.20 to $5.40.
Note: any increases shippers may see with this update are in addition to the "temporary" 8% surcharge that went into effect in April for Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select.
USPS rates for Market Dominate products like First-Class Mail, Periodicals, and Marketing Mail will also be changing on July 12.
The rate adjusts come as USPS continues to grapple with significant quarterly losses, recently telling Congress that the Postal Service will be out of cash by the end of 2026 without drastic action.
Consumer advocacy group Keep US Posted continues to push back on Postmaster General David Steiner's to raise the Postal Service's borrowing authority, arguing USPS has a cost control problem, not a revenue problem and urging reforms instead of bailout.
“USPS is staring at another huge quarterly loss and faces financial ruin unless Congress acts, but when Congress steps in, it should insist on real, enforceable reform,” said former Congressman Kevin Yoder (R-Kan.), executive director of Keep US Posted.
“The core challenge for USPS is spending and productivity, not revenue. Former Postmaster General Louis DeJoy’s Delivering for America plan and its repeated above-inflation stamp hikes are hurting, not helping, USPS and the mailing public..."
“...Raising the Postal Service’s borrowing authority or providing funds without without guardrails would be a blank check that only delays the inevitable collapse of the agency’s finances and leads to a massive taxpayer bailout...any financial assistance should be tied to a CPI-based price cap, stronger Postal Regulatory Commission oversight, and measurable cost controls that protect universal service and affordability.”
Meanwhile, on X Ross Marchand from the Taxpayers Protection Alliance is calling out some of the perks of being a USPS governor.

As always, shippers who sell on marketplaces like Etsy and eBay, will be a particularly impacted by any rate increase as selling and advertising fees are charged on total transaction amounts including tax and shipping, resulting in a de facto fee increase that will eat even further into margins.
And not only does eBay collect more in Final Value Fees and Promoted Listings ad fees when shipping rates go up, they also get an unearned bump in Gross Merchandise Volume for their quarterly earnings reports that artificially inflates these important financial figures.
