This month’s Surcharge Watch features a first: USPS. While UPS continues rolling out new fees, USPS is making a pricing move that could have lasting implications for shippers’ carrier mix strategy. Here’s what shippers need to know about the latest shipping surcharges.

USPS Announces 8% Rate Increase 

  • Effective Date: April 26, 2026, through January 17, 2027
  • Details: USPS filed notice with the Postal Regulatory Commission (PRC) on March 25, 2026, announcing an 8% increase on base postage prices for Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select. No other products or services are affected, including First-Class Stamps. The increase is classified as a transportation-related, time-limited adjustment designed to better align costs with current market conditions.
  • Why It Matters: USPS has long been one of the more predictable carriers when it comes to pricing. For shippers relying on Ground Advantage as a stable, low-cost option for lightweight parcels, this increase is worth modeling immediately — especially across high-volume lanes where even single-digit percentage changes can compound quickly.

Why This USPS Change is Bigger Than an 8% Increase

Last month, USPS announced an expected 8% increase to help offset rising fuel costs. This announcement drew headlines and attention from many in the industry as a notable first for the Postal Service. However, the details released in the announcement paint a far more significant change for shippers in 2027: permanence.  

In the official press release, USPS specifically described the pricing adjustment as a bridge to “a permanent mechanism to reflect market conditions in prices for competitive products.”

In other words, USPS isn’t just raising rates. It’s laying the groundwork for a structural shift in how it prices parcel services.

For years, shippers have used USPS as a reliable cost anchor; predictable pricing, no fuel surcharges, and none of the demand-based volatility that makes FedEx and UPS budgeting so difficult. If USPS builds a formula-based transportation adjustment into its permanent rate structure, that calculus changes. Shippers that leverage USPS as a partner would be subject to the same market forces that drive surcharges in other major carriers.

The Reveel team will be watching a few things closely between now and the January 17, 2027, sunset date:

  • What the “permanent mechanism” actually looks like when formally proposed, and whether it’s indexed to external benchmarks such as diesel prices or spot trucking rates, or left to USPS discretion
  • How USPS parcel volume trends over the next several months (which will likely inform whether this approach becomes permanent)
  • Whether shippers begin shifting volume in response, and how that affects the competitive dynamics across all three major carriers

Think of the January 2027 expiration as a decision point. If volume holds and the mechanism proves effective, shippers should expect something similar (or broader) to become a permanent fixture in USPS pricing.

The bottom line: shippers and consultants only modeling the expected 8% increase are missing the bigger picture. The question everyone ought to be asking now is, what does a carrier mix strategy look like if USPS pricing becomes as dynamic as everyone else’s? That’s a question worth answering now (and not in Q4).

UPS Shipping Surcharges April & May 2026

Customs Brokerage PGA Disclaimer Fee Increase

  • Effective Date: April 13, 2026
  • Details: The Partner Government Agency (PGA) Disclaimer Fee increases from $1.00 to $2.50 per disclaimer — a 150% jump.
  • Why It Matters: On a per-disclaimer basis, this may seem minor. But for international shippers processing high volumes of customs entries, the increase compounds quickly and should be factored into landed cost calculations.

Ground Saver Non-Compliant Label Fee

  • Effective Date: May 4, 2026
  • Details: A $5.00 per package fee will apply to UPS Ground Saver shipments that fail to comply with labeling requirements outlined in the UPS Guide to Labeling Supplement, or that aren’t processed using the latest version of an approved shipping system at the time of shipment.
  • Why It Matters: $5.00 per package can add up fast for high-volume shippers who haven’t updated their systems or labeling workflows. Operations and IT teams should verify compliance now, before the effective date. More details are available on the UPS Ground Saver page.

New Shipping Cost Structures Mean Shippers Must Act Now

Between USPS’s structural pricing shift and UPS’s new fees, April is a good time to pressure-test your current carrier strategy. A few places to start:

  • Model the USPS 8% increase before it takes effect on April 26 — especially if you’re running heavy Ground Advantage or Parcel Select volume.
  • Revisit your carrier mix strategy with the assumption that USPS pricing may become more dynamic long-term.
  • Verify UPS Ground Saver labeling compliance before May 4 and update cost calculations to reflect the new PGA Disclaimer Fee.
