The Annual Rate Review Is Dead. Peak Surcharge Season Just Proved It.

FedEx went first on July 22, USPS filed on August 25, UPS published on August 26, and OnTrac's schedule landed the same week. The tables are everywhere by now.

Most parcel programs still revolve around one event a year. The general rate increase (GRI) gets announced, the negotiation happens, the discount gets signed and a number goes into the budget. That model assumes your price is set once a year, but - it isn’t. It hasn’t been for a while.

The year your prices actually changed

January is the part everyone plans for. UPS and FedEx each posted a 5.9% general rate increase; USPS raised Priority Mail an average of 6.6% and Ground Advantage 7.8%. Shippers ran the numbers and moved on; carriers didn't.

On April 26, USPS added a “temporary” 8% increase across Priority Mail Express, Priority Mail, Ground Advantage and Parcel Select, running through January 17, 2027 - all of peak, plus the start of the next annual cycle

On July 12, USPS tightened its dimensional weight divisor from 166 to 139 and began rounding package dimensions up to the next whole inch. Though the rate in this case didn’t change, the math to get there did. Dimensional weight is how carriers charge for packages that take up space without weighing much, and a smaller divisor produces a bigger billable weight. A 12-inch cube that billed at 11 pounds in June bills at 13 pounds today. For anyone shipping light and bulky, that quiet change can outrun the January increase, and it never appears as an increase at all.

Then four peak schedules landed, each with a structurally different mechanism. With peak schedules arriving in late July and August, we are brought to the current moment. UPS's baseline measurement window opened August 30 and closes September 26. What you ship in these four weeks sets the yardstick UPS will price your entire peak season against. From October through January, UPS and FedEx recalculate qualifying shippers' surcharge rates every week.

One negotiation a year. Multiple rounds of price changes, several of which never touch the negotiated rates at all. The annual rate review isn't necessarily wrong, but it's answering a question the carriers stopped asking.

Three traps in the fine print

Beyond the mechanisms, three specific provisions in this year's peaks season schedules deserve more attention than the headline rates are getting:

• The biggest increase landed on the fee every package pays. UPS raised its entry-level demand fee - charged on every qualifying package regardless of volume - by 25% on ground residential and 22% on air. The top tiers, with their attention-grabbing $8.00-plus ceilings, rose only 6.6% to 9.4%. FedEx followed suit. Model peak off last year's actuals, adjust only the scary numbers, and you'll miss most of your increase.
  
  
• The cliffs reprice your whole week - and the big one reprices your whole season. UPS's tiers aren't marginal: the highest tier you reach applies to every package in that service level for the whole week, not just the volume above the line. Ship 20,000 ground residential packages in a peak week at the standard $0.75 fee and you owe $15,000. Ship one more and you've crossed into the volume tables – and if that week sits well above a quiet June baseline, every package prices at the $8.00 top tier: $160,008. One package, a $145,000 swing, and every week after runs on the tiered tables. Somebody in your operation should know, this week, what counts put you at 20,000 - and at 105%, 125% and 150% of baseline.
  
  
• Your discounts probably don’t apply. UPS's tariff says no waiver or discount applies to demand surcharges unless UPS agrees in writing with specific reference to them, and they stack cumulatively when a package triggers more than one. FedEx says contracted discounts or caps on its standard residential delivery charge do not apply to the volume-based Demand RDC. You can hold a strong agreement and still pay published rates on the charges that define your most expensive shipping weeks of the year. If your last rate review didn't address peak by name, it didn't address peak.

If your volume is flat, you're paying for someone else's December

Peak surcharges exist, officially, to price a capacity crunch that is overwhelmingly consumer e-commerce. A manufacturer shipping components or a distributor running steady replenishment doesn't create the December surge - but additional-handling demand fees near $12 a package and oversize fees north of $117 start in late September and hit industrial profiles with no seasonality at all. And because the baselines measure you against your own summer, an ordinary strong month can register as a "surge."

What you should do before October

The calendar is short but not closed. Before October:

• Know where your September lands, before the 26th. UPS substitutes your Aug 30 - Sept 26 average as the baseline if it falls below 80% of June. A soft September makes your December more expensive - the opposite of intuition.
  
  
• Turn your tier boundaries into package counts. Translate 105%, 125%, and 150% of baseline into actual weekly package counts by service level, and make sure someone is watching them during peak. The cliff math is only survivable if you can see it coming.
  
  
• Calculate the USPS number. Flat pricing by weight and zone means your USPS peak exposure is arithmetic, not forecasting. Re-rate your profile under the July DIM rules first: a parcel that crossed a weight band in July pays a higher peak surcharge per band in October.
  
  
• Search your agreement for the word “demand.” Not "residential" or "accessorial," but demand. If peak surcharges aren't referenced specifically, assume published rates and model accordingly. If concessions exist, confirm they haven't quietly expired.
  
  
• Model the stack, not the line. A single December package can cumulatively carry base transportation, fuel, an ordinary accessorial, that accessorial's demand add-on and a service-level demand fee. No single figure in any published table describes what that package costs.

The bottom line

The 2026 GRI was 5.9% and nobody's effective increase was actually 5.9%. The impact of the GRI typically falls between 10-12% (or more). Add to that April's USPS measure, July's dimensional change, four peak schedules, tier mechanics that reprice whole weeks, and demand fees built to sit outside negotiated discounts, the real number is set continuously.

The annual rate review is dead because it's no longer where the money moves. Shippers who treat parcel pricing as a year-round discipline - modeled weekly, read at the tariff level, managed operationally as much as contractually - will know their peak number before November. Everyone else will find out one invoice line at a time.
