FedEx, UPS, USPS, and Amazon Shipping have all confirmed their 2026 peak season surcharges, and every one of them costs more than it did last year. The added fees start rolling in as early as late September, stack on top of fuel surcharges that were already elevated in 2026, and hit their highest rates during the exact weeks when order volume peaks: late November through late December.
If your business ships products, this is the single biggest predictable cost swing on your calendar between now and January. Here is what each carrier is charging, when it starts, and what you can actually do about it.
Peak season surcharges are temporary per package fees that carriers add on top of your regular contracted rates during the busiest shipping weeks of the year. Carriers frame them as the cost of keeping up with holiday volume. For shippers, they are simply a higher bill during the season when volume, and therefore total exposure, is already at its highest.
Three things make 2026 different from a typical year:
FedEx published its 2026 demand surcharges on July 22. Additional Handling, Oversize, and Ground Unauthorized Package fees begin September 28. Express, Ground Residential, Home Delivery, and Ground Economy surcharges begin October 26. All surcharges run through January 17, 2027, with the highest rates in effect from November 23 through December 27.
FedEx also restructured Express pricing this year, replacing last year's single "All Express Parcel" surcharge with separate fees by delivery speed. Brands that upgrade to faster service to protect a delivery promise will see a bigger jump than in past years.
UPS published its schedule in late August, phased across two start dates. Additional Handling, Large Package, and Over Maximum Limits surcharges began September 27. Ground and Air demand surcharges began October 25. All surcharges run through January 16, 2027, with the highest rates in effect from November 22 through December 26.
High volume shippers should also check UPS's tiered surcharge for residential volume that runs above baseline. The jump between tiers is steep, and it applies early in the season, not just during the peak weeks.
USPS is taking a different approach than the other carriers. Instead of flat per package surcharges, it is applying a temporary average rate increase of about 6 percent to Ground Advantage, Priority Mail, Priority Mail Express, and Parcel Select, in effect from October 4, 2026 through January 17, 2027.
Because the increase scales with weight and zone rather than a flat fee, the dollar impact varies widely, from about $0.40 on a light, short zone package up to $18.20 on a heavy, long haul parcel. This is also the first year the peak increase stacks on top of a separate 8 percent transportation related rate increase USPS implemented in April 2026, so shippers comparing this year's rates to last year's are really comparing against two increases, not one.
Amazon Shipping's 2026 peak surcharges run October 25, 2026 through January 16, 2027, split into three pricing windows, with the highest rates from November 22 through December 26.
Amazon's ongoing 3.5 percent fuel and logistics surcharge, in place since April 2026, applies on top of these fees. Sellers using Fulfillment by Amazon, Multi Channel Fulfillment, or Buy with Prime should also plan for separate holiday fulfillment fee increases from October 15 through January 14, 2027, averaging about $0.32 per unit. This is Amazon Shipping's first peak season open to businesses beyond Amazon.com sellers, and its published fees closely track UPS and FedEx despite Amazon's push for share with lower base rates.
| Carrier | Surcharges begin | Highest rates | Ends |
|---|---|---|---|
| FedEx | Sept 28 (phased), Oct 26 (full) | Nov 23 to Dec 27 | Jan 17, 2027 |
| UPS | Sept 27 (phased), Oct 25 (full) | Nov 22 to Dec 26 | Jan 16, 2027 |
| USPS | Oct 4 | Flat for the full period | Jan 17, 2027 |
| Amazon Shipping | Oct 25 | Nov 22 to Dec 26 | Jan 16, 2027 |
Peak season surcharges are not avoidable, but the amount your business actually pays is not fixed either. A few places to look before the highest rates take effect:
This is also the season where working with a shipping intelligence partner pays for itself fastest. ShipPlug analyzes carrier agreements, audits every invoice for errors, automates refunds on late shipments, and matches businesses with the right 3PL, all without requiring any change to how a business already ships. Clients working with ShipPlug cut shipping costs by up to 50 percent, and the relationship does not stop once an agreement is signed. Rates get rechecked as the market changes, all year, not just once.
The earliest charges begin September 27 and 28, when UPS and FedEx apply their first wave of Additional Handling, Large Package, and Oversize surcharges. USPS increases start October 4. The broader FedEx, UPS, and Amazon Shipping per package surcharges on residential, ground, and air services begin between October 25 and October 26.
UPS and Amazon Shipping surcharges run through January 16, 2027. FedEx and USPS surcharges run through January 17, 2027.
FedEx charges its highest rates from November 23 through December 27. UPS and Amazon Shipping charge their highest rates from November 22 through December 26. USPS applies one flat increase for the entire period, with no separate peak tier.
UPS and FedEx posted the largest percentage increases on their core per package fees, both in the 22 to 25 percent range for Ground Residential and Air or Express services. USPS applied a 6 percent average increase, though the dollar impact on individual heavy or long haul packages can be larger.
The surcharges themselves apply broadly and cannot be opted out of once a shipment meets the criteria. What businesses can control is exposure: negotiating agreement terms, auditing invoices for billing errors, adjusting packaging to avoid Additional Handling and Oversize triggers, and reviewing which carrier and service level fits each shipment instead of defaulting to one option.
