Updated August 26, 2026.
Peak season hasn’t started yet, but higher shipping costs have.
Brands preparing their omnichannel fulfillment for Black Friday, Cyber Monday, and the holiday rush are already facing 2026 peak season surcharges, adding to a parcel market that is already more expensive because of fuel, carrier pricing changes, and tighter transportation capacity. As BFCM approaches, this year is shaping up to be different from the past several peak seasons.
2025 recap
In 2025, the primary concern was how much additional cost carriers would layer onto packages during the busiest weeks of the year. In 2026, brands also must account for elevated costs that began months before the holiday shipping window.
The TD Cowen/AFS Freight Index1 found that the ground parcel rate per package reached a record 42.4% above its January 2018 baseline in Q2 2026, up 6.9% year over year. Average net fuel surcharges per package jumped 40% year over year during the quarter.
That changes the math. Peak season surcharges are being added to fuel fees, residential charges, dimensional pricing, and other accessorials that are already putting pressure on cost per order.
Understanding when these charges apply, how they differ from 2025, and which announcements are still pending can help brands plan shipping budgets before holiday volume ramps up.
What are peak season surcharges?
Peak season surcharges are temporary fees carriers assess during periods when package volumes, network utilization, or operating costs are elevated.
Carriers frequently use the term “demand surcharge,” since these charges can apply whenever network conditions warrant them, rather than only during the traditional holiday peak. FedEx, for example, bases demand surcharges on shipment volume, capacity, and operating costs.
During the holidays, these fees can apply to ordinary residential shipments as well as packages that require additional handling, exceed certain dimensions, or fall into high-volume shipper tiers.
They also do not necessarily replace existing surcharges. A package can be subject to a peak or demand fee while also carrying a fuel surcharge, residential delivery charge, dimensional weight adjustment, or additional handling fee.
The stacking effect is important in 2026 as it affects an already volatile market.
What’s different about 2026 peak season surcharges?
Last year, peak fees themselves were the primary story. This year, the cost environment surrounding them matters almost as much as the published holiday rates.
Here is how the 2026 season is taking shape compared with 2025:
| Area | 2025 peak season | 2026 peak season so far |
| FedEx Ground Residential | Peak demand fee reached $0.65 per package | Peaks at $0.80,2 a 23% increase |
| FedEx Ground Economy | Peaked at $3.55 | Peaks at $4.05,2 about 14% higher |
| FedEx Express | One primary surcharge structure covered multiple expedited services | Overnight and 2Day/Express Saver services now have separate rates |
| Fuel | Elevated, but less central to the peak story | Fuel fees were already significantly higher before peak. Net parcel fuel surcharge per package rose 40% YoY in Q21 |
| USPS | Separate holiday commercial price table | An 8% temporary transportation-related increase3 has already been in effect since April; and USPS has now announced an additional holiday increase averaging 6% from Oct. 4, 2026-Jan. 17, 2027.12 |
| Amazon FBA | Holiday fulfillment fees averaged about $0.32 more per unit | Average holiday increase remains about $0.32, but a new 3.5% fuel and logistics surcharge also applies4 |
| Rail/intermodal | Not covered in the previous Kase article | Union Pacific introduced a peak surcharge for certain low-volume intermodal shippers months before parcel peak5 |
| UPS | Demand surcharges ranged from $0.40 to $2.05 for standard Ground Residential, Ground Saver, and Air packages | Demand surcharges range from $0.50 to $2.50, with core holiday Ground Residential/Ground Saver fees up 25% and Air fees reaching $2.5015 |
| Amazon Shipping | Per-package peak surcharge ranged from $0.40 to $0.60 | Per-package demand surcharge ranges from $0.50 to $0.75, a 25% increase from the equivalent 2025 periods17 |
Most commercial holiday increases are also higher in dollar terms than last season. For example, the surcharge for a 0-3 lb. commercial Priority Mail or Ground Advantage shipment in Zones 1-4 rises from $0.30 in 2025 to $0.40 in 2026. For 26-70 lb. or oversized Ground Advantage shipments in Zones 5-9, the increase moves from $5.50 to $7.70. A 26-70 lb. Priority Mail Express commercial shipment to Zones 5-9 rises from a $13 holiday increase last year to $18.20 this year.
In other words, many of the surcharge structures remain familiar, but the starting point is more expensive.
FedEx peak surcharges for 2026
FedEx was the first major national parcel carrier to publish a complete 2026 holiday demand surcharge schedule, releasing its update on July 22.2 Most of its fixed peak season surcharges are higher than last year, with the largest percentage increase hitting ordinary Ground Residential and Home Delivery packages.
FedEx 2026 holiday fees
| Surcharge | Sept. 28-Nov. 22, 2026 | Nov. 23-Dec. 27, 2026 | Dec. 28, 2026-Jan. 17, 2027 |
| Additional Handling | $8.80 | $11.85 | $8.80 |
| Oversize Charge | $95.75 | $117.25 | $95.75 |
| Ground Unauthorized Package | $535 | $595 | $535 |
Additional demand surcharges begin Oct. 26:
| Service | Oct. 26-Nov. 22 | Nov. 23-Dec. 27 | Dec. 28-Jan. 17 |
| First Overnight, Priority Overnight, Standard Overnight | $1.30 | $2.55 | $1.30 |
| 2Day A.M., 2Day, Express Saver | $1.20 | $2.35 | $1.20 |
| Ground Residential/Home Delivery Residential | $0.50 | $0.80 | $0.50 |
| Ground Economy | $2.55 | $4.05 | $2.55 |
Source: FedEx.
Compared with 2025, the peak Ground Residential fee rises from $0.65 to $0.80, or roughly 23%. Ground Economy increases from $3.55 to $4.05. Peak Additional Handling rises from $10.90 to $11.85, Oversize moves from $108.50 to $117.25, and the Ground Unauthorized Package fee increases from $545 to $595.
FedEx also changed the way its Express surcharge is structured. Last year, the same demand fee generally applied across several expedited services. This year, Overnight services have one rate while 2Day and Express Saver have another.
High-volume FedEx shippers face another layer
Enterprise-level customers shipping more than 20,000 residential and Ground Economy packages during a calculation week can also face FedEx’s Demand Residential Delivery Charge.
For 2026, FedEx compares a customer’s calculation-week volume with its average weekly residential and Ground Economy volume from June 1 through June 28, 2026. Depending on how far holiday volume exceeds that baseline, the additional Ground/Home Delivery fee can reach $8 per package, while Express services can reach $9.35 per package.
That baseline period has already passed, which means brands can begin modeling their likely surcharge tiers now rather than waiting until November.
UPS peak surcharges for 2026
UPS’s 2026 holiday demand surcharges15 includes fees beginning September 27 and remaining in effect through January 16, 2027. Like FedEx, UPS is raising both package-specific fees and the demand charges applied to common residential and air services.
The highest rates will apply during the core holiday period from November 22 through December 26. Additional Handling will reach $11.90 per package, up from $10.80 in 2025. The Large Package Surcharge rises from $107 to $117.50 at its peak, while the Over Maximum Limits surcharge increases from $540 to $590.
| Surcharge | Sept. 27-Nov. 21 | Nov. 22-Dec. 26 | Dec. 27-Jan. 16 |
|---|---|---|---|
| Additional Handling | $8.75 | $11.90 | $8.75 |
| Large Package Surcharge | $96.25 | $117.50 | $96.25 |
| Over Maximum Limits | $530 | $590 | $530 |
Demand surcharges for UPS Ground Residential, Ground Saver, and Air packages begin October 25. Ground Residential and Ground Saver reach $0.75 per package during the core holiday period, compared with $0.60 in 2025, a 25% increase. UPS Next Day Air and other eligible Air services will reach $2.50 per package, up from $2.05 last year.
| Service | Oct. 25-Nov. 21 | Nov. 22-Dec. 26 | Dec. 27-Jan. 16 |
|---|---|---|---|
| UPS Ground Saver | $0.50 | $0.75 | $0.50 |
| UPS Ground Residential | $0.50 | $0.75 | $0.50 |
| UPS Next Day Air | $1.35 | $2.50 | $1.35 |
| All Other UPS Air | $1.35 | $2.50 | $1.35 |
Source: UPS 2026 Demand Surcharges PDF
Higher-volume shippers face another surcharge structure. UPS applies its higher-volume schedule to customers whose combined Ground Residential, Ground Saver, Next Day Air Residential, and other eligible Air Residential volume exceeded 20,000 packages in any week after October 2025. During the core holiday period, residential Air surcharges can reach $9.35 per package for volume above 400% of baseline, while Ground Residential and Ground Saver can reach $8 per package.
UPS defines the baseline as average weekly volume by service level from May 31 through June 27, 2026. However, if average weekly volume from August 30 through September 26 falls below 80% of that June-period average, UPS will use the later period as the baseline instead.
Compared with 2025, UPS’s handling and size-related demand charges are roughly 6% to 10% higher, while its flat service-level holiday charges increased about 22% to 25%. UPS also expects U.S. package volume to increase approximately 24% from the third to fourth quarter, similar to the seasonal jump it experienced last year.16
USPS holiday shipping costs for 2026
USPS has now added a traditional holiday price increase to an already more expensive 2026 shipping environment.
An 8% temporary transportation-related price increase took effect April 26, 2026 and remains in place through January 17, 2027.3 On August 25, USPS announced another temporary price adjustment for the holiday peak, pending favorable review by the Postal Regulatory Commission. The seasonal rates are scheduled to take effect October 4 and remain in place through January 17, 2027.12
The holiday adjustment will increase affected USPS package rates by an average of 6%,13 compared with average increases ranging from 4.9% to 5.8% during the 2025 peak season. Actual increases vary by service, package weight, and zone. That means the seasonal increases arrive after the 8% transportation-related adjustment already took effect earlier this year.
There is another change brands should account for even though it is not technically a peak surcharge. Effective July 12, USPS lowered its dimensional-weight divisor from 166 to 139, bringing its calculation closer to the approach typically used by FedEx and UPS.8 That can increase billable weight for lightweight, bulky ecommerce shipments.
For some Ground Advantage Commercial shipments, July pricing changes also increased costs by as much as $2.04 depending on weight and zone, making package dimensions more consequential this peak season, particularly when higher billable weight is combined with the transportation-related and holiday price increases already affecting USPS shipments.

Amazon holiday fulfillment fees for 2026
Brands should distinguish between Amazon fulfillment fees and Amazon Shipping parcel surcharges. They are separate programs.
Amazon has announced its 2026 holiday peak fulfillment fees4 for Fulfillment by Amazon, Remote Fulfillment with FBA, Multi-Channel Fulfillment, and Buy with Prime. The peak period runs from October 15, 2026, through January 14, 2027.
The average increase is $0.32 per unit, the same average increase as last year.
What makes 2026 more expensive is the 3.5% fuel and logistics-related surcharge9 Amazon introduced in April. That surcharge will remain in effect during peak and applies on top of the holiday fulfillment fee.
For example, Amazon lists a large-standard T-shirt fulfillment fee of $6.14 outside peak and $6.53 during peak,10 before accounting for the additional fuel and logistics surcharge.
Amazon is also advising sellers to get inventory into its fulfillment network by October. The company has warned that fulfillment centers may have lower inbound capacity limits during November and December as operations shift toward processing customer orders.
What about Amazon Shipping?
Amazon Shipping will apply demand surcharges across three holiday periods: October 25-November 21, November 22-December 26, and December 27-January 16, 2027. The standard per-package demand surcharge will be $0.50 during the first and final periods and $0.75 during the core holiday window. That is 25% higher than Amazon Shipping’s 2025 per-package peak charges of $0.40, $0.60, and $0.40, respectively.17
| Demand surcharge | Oct. 25-Nov. 21, 2026 | Nov. 22-Dec. 26, 2026 | Dec. 27, 2026-Jan. 16, 2027 |
|---|---|---|---|
| Per-package Demand Surcharge | $0.50 | $0.75 | $0.50 |
| Additional Handling Fee | $8.75 | $11.90 | $8.75 |
| Large Package Fee | $96.25 | $117.50 | $96.25 |
| Extra Heavy Package Fee | $530 | $590 | $530 |
Source: Amazon
The increases extend beyond the standard package fee. During the busiest holiday window, Amazon Shipping’s Additional Handling Fee rises from $10.80 in 2025 to $11.90 in 2026. The Large Package Fee increases from $107 to $117.50, while the Extra Heavy Package Fee climbs from $540 to $590.
Amazon notes that these demand surcharges are added to contracted shipping rates. However, the carrier will continue to offer no additional residential surcharges or weekend delivery fees during peak season, with seven-day delivery available depending on location.
Brands comparing parcel carriers should note that Amazon Shipping’s headline demand surcharge is higher this year, but evaluating total shipping costs requires accounting for the different residential, handling, package-size, and other fees that each carrier may apply.
Peak season costs are reaching further upstream
Parcel delivery is only one place brands may encounter peak-related transportation costs this year.
Union Pacific imposed a peak season surcharge on certain low-volume domestic intermodal shippers in Southern California beginning June 21,5 months before parcel carriers enter their traditional holiday surcharge periods. Reporting on the change described a $500-per-container charge for customers generally moving fewer than five loads per week using UP-owned EMP and UMAX equipment.
The timing matters for brands importing inventory through West Coast ports. A rail or intermodal surcharge affects the cost of moving inbound inventory toward a fulfillment center before the final parcel shipment ever begins.
Container import patterns are also unusual this year. U.S. importers pulled significant volume forward earlier in 2026 in response to tariffs and rising transportation costs, with Reuters reporting in early August that the early import surge was beginning to recede even as fuel and canal-related costs remained elevated.
Brands that manage international freight, drayage, rail, and parcel separately should look at total landed and fulfillment cost rather than budgeting for parcel peak surcharges in isolation.
Other carriers brands should watch
Carrier diversification can help limit exposure to one surcharge structure, but alternative carriers are facing the same fuel environment.
OnTrac, for example, is assessing a 24% fuel surcharge for the week of August 10-16, 2026.11 Its fuel fee applies to the net package rate plus applicable additional fees and surcharges.
| Carrier | 2026 holiday surcharge status as of Aug. 11 |
| OnTrac | OnTrac recently published its 2026 demand surcharge schedule.14 Most peak-related fees will apply from September 26, 2026, through January 15, 2027, while its residential demand surcharge begins October 24. |
| DHL eCommerce | 2026 U.S. holiday peak schedule not yet identified |
| UPS | Holiday demand schedule pending |
| Amazon Shipping | Holiday parcel schedule pending |
| USPS | 8% temporary transportation increase already active; additional holiday increase averaging 6% scheduled for Oct. 4-Jan. 17, pending PRC review |
Brands using these carriers should check contracted rate cards as announcements arrive because public list pricing may not reflect negotiated terms.
How peak season surcharges can stack
One of the easiest mistakes in holiday shipping forecasts is modeling one surcharge at a time.
A FedEx residential shipment, for example, may be subject to a base transportation charge, the ordinary Residential Delivery Charge, the holiday Ground Residential Demand Surcharge, and a fuel surcharge. A high-volume shipper may also face the separate Demand Residential Delivery Charge. If the package triggers dimensional or handling criteria, additional charges can apply as well. FedEx explicitly states that its high-volume Demand Residential Delivery Charge is assessed in addition to its ordinary Residential Delivery Charge.
The question is therefore not simply, “What is the peak surcharge?” It is, “What will this package actually cost to ship during this specific week?”
That is the number brands should use when evaluating free shipping, promotional pricing, and holiday margin.
Reduce 2026 peak season fees with these strategies
While it can feel like every peak season surcharge is burning a hole in a brand’s wallet, practical strategies exist to offset fees. Consider the tips below to maintain a healthy holiday shipping season.
Keep your DIM weight down
Have you ever received a box within a box? Shipping fees take many forms, but dimensional weight is most certainly one of them. DIM weight is a primary way shipping carriers determine costs, taking both package weight and dimensions into account.
Merchants who utilize smaller boxes or mailer envelopes to reduce packaging dimensions can lower costs on each shipment and reduce the likelihood of additional handling fees.
Packaging deserves additional attention this year because USPS lowered its dimensional-weight divisor to 139 in July, making light but bulky parcels more expensive under certain services.
Incentivize early holiday shopping
The easiest way to avoid the highest peak season surcharges is to encourage customers to shop before they hit. Easier said than done!
Try incentivizing earlier purchasing through early-bird discounts or promotions. Early shipments can avoid the highest surcharges that apply during peak demand weeks, helping reduce costs while supporting timely delivery.
For FedEx, the most expensive fixed-fee period runs from November 23 through December 27 this year.
Compare rates among multiple carriers
Sticking with one carrier throughout the holiday season means a brand is tied to that carrier’s particular surcharge structure. Instead, compare rates among UPS, FedEx, USPS, Amazon Shipping, and regional carriers to determine which option makes the most sense for each package and destination.
Rate-shopping technology can make this easier by comparing carrier selection, transit time, cost, and delivery requirements at the package level.
This is useful in 2026 because fuel, residential, peak, and handling fees vary considerably by carrier. The lowest published base rate may not produce the lowest final transportation cost.
Consider multi-node fulfillment
For brands with a nationwide customer base and high order volume, a multi-node fulfillment approach can position inventory closer to customers.
Shorter delivery distances can reduce zone-related costs and exposure to extended or remote-area delivery charges while improving transit times.
It can also give brands more carrier options by origin, rather than forcing every holiday order through the same node and carrier mix.
Determine your free shipping threshold
Every shipment counts when a brand is footing the shipping bill. Setting free shipping thresholds can increase average order value and help offset higher shipping costs. It can also encourage customers to consolidate purchases into fewer orders.
A free shipping threshold works best when brands determine a level that supports both conversion and margin. A threshold that is too high could turn customers away, while one that is too low may leave the brand absorbing too much of the transportation cost.
For 2026 planning, brands should calculate the threshold using expected holiday cost per order, including applicable peak and fuel surcharges, rather than an annual average shipping rate.
Explore omnichannel strategies
Retailers may also be able to reduce parcel delivery costs through options such as buy online, pick up in store. BOPIS removes the residential last-mile shipment from the transaction while giving customers another way to receive holiday purchases.
For ecommerce merchants without their own stores, retail partnerships and other pickup options can provide similar flexibility.
Model the full surcharge stack
This year, modeling only the published peak surcharge will underestimate transportation costs. Brands should calculate expected cost by package type, service, week, destination, and carrier, including fuel, residential, dimensional-weight, additional handling, and demand fees that may apply simultaneously.
This is also the right time to compare forecast volume with carrier baseline calculations. For FedEx enterprise shippers, the June baseline period has already been established, so brands can estimate which high-volume surcharge tier they may enter before peak begins.
Navigating demand surcharges with Kase
Navigating additional fees during peak season can be challenging, but proper planning and strategic adjustments can help ecommerce merchants protect profitability during the holiday shipping season.
Start by reviewing shipping options, implementing early holiday promotions, and using technology to evaluate fulfillment and transportation costs.
In 2026, that review should extend beyond the carrier’s headline peak rate. Fuel, dimensional pricing, residential charges, service selection, shipment origin, and package characteristics all affect what a holiday order ultimately costs to deliver.
A 3PL partner should be able to help brands evaluate those variables, compare carrier services, and determine when different fulfillment nodes or shipping methods make financial sense.
Kase’s customizable rate-shopping capabilities allow brands to compare shipping options using the factors that matter to each order, including cost and delivery speed. Combined with a distributed fulfillment network, that gives brands more options for managing holiday parcel costs as carrier pricing changes.
Peak season surcharge FAQs
Are peak season surcharges and demand surcharges the same thing?
They are closely related, but carriers use the terminology differently. “Peak” typically refers to temporary charges during predictable high-volume periods such as the holidays. “Demand surcharge” is broader and can be applied when volume, capacity, or operating costs warrant additional pricing. FedEx now primarily uses “Demand Surcharge,” while Amazon Shipping describes peak surcharges as a category of demand surcharge.
Do fuel surcharges replace peak season surcharges?
No. Fuel and peak or demand surcharges can apply at the same time. That distinction is particularly important in 2026 because fuel fees rose substantially before holiday demand surcharges were announced.
How is baseline volume calculated?
It depends on the carrier and program. For FedEx’s 2026 enterprise Demand Residential Delivery Charge, holiday calculation-week volume is compared with average weekly residential and Ground Economy volume from June 1 through June 28, 2026. FedEx then applies a two-week lag between the calculation week and the week when the surcharge is billed.
Are all 2026 peak season surcharge rates available yet?
No. As of August 11, FedEx and Amazon’s fulfillment programs have published major 2026 holiday fee information, while the complete UPS holiday schedule and Amazon Shipping parcel schedule remain pending. USPS has now announced its 2026 holiday adjustment, with temporary increases averaging 6% across affected package services from October 4 through January 17, pending PRC review. Those holiday rates will overlap with the 8% transportation-related increase USPS implemented in April. UPS and Amazon Shipping remain among the major schedules still pending.
Kase will update the carrier tables as those remaining announcements are released.
