Peak Season Surcharges 2026: FedEx, UPS and USPS Dates, Rates, and What Your 3PL Passes Through

The 2026 windows at a glance

Carrier demand surcharges are the fourth-quarter fees FedEx, UPS and USPS add on top of base rates while holiday volume runs above capacity. For a brand shipping through a 3PL they arrive twice: on the carrier invoice, and in how the provider passes them through. This page keeps the 2026 windows and the published amounts in one place, each cited to the carrier's own announcement, and then covers the part the rate tables skip: how 3PLs handle surcharges, what to ask before peak, and when a provider's carrier mix softens the hit. Holiday shipping deadlines are a different table with different publication dates; those live on our peak season readiness guide.

2026 to 2027 peak surcharge windows, from each carrier's own announcement. Amounts follow in the carrier sections below.

FedEx demand surcharges

FedEx published its 2026 U.S. package demand surcharges on July 22, 2026 on its demand surcharges page, which also notes that FedEx reserves the right to reassess them. The schedule has three windows, and the middle one, November 23 to December 27, carries the highest amount in every row.

Handling, oversize and unauthorized charges

Per package. Windows: September 28 to November 22, 2026; November 23 to December 27, 2026; December 28, 2026 to January 17, 2027.

Per-package demand surcharges

Per package. Windows: October 26 to November 22, 2026; November 23 to December 27, 2026; December 28, 2026 to January 17, 2027.

The residential delivery charge for large shippers

Separately, FedEx applies a Demand Residential Delivery Charge to enterprise customers that ship more than 20,000 residential and FedEx Ground Economy packages in a calculation week. The amount is set by a peaking factor: that week's residential volume divided by the customer's weekly average for June 1 to 28, 2026, applied two weeks later, with application weeks running October 26, 2026 through January 17, 2027. It is charged in addition to the standard residential delivery charge, and FedEx states that contracted discounts or caps on that charge do not apply to it. Few brands ship at that scale on their own account; a 3PL shipping consolidated volume can, which is one reason to ask how a provider allocates account-level surcharges (see the pass-through section below).

USPS holiday price change

On August 25, 2026 the Postal Service announced a temporary price change for the 2026 holiday season and filed it with the Postal Regulatory Commission (Docket No. CP2026-10). Pending the Commission's review, the temporary rates take effect at 12 a.m. CT on October 4, 2026 and stay in place until 12 a.m. CT on January 17, 2027. They apply to Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select, at retail and commercial prices. Unlike FedEx's schedule, the USPS increase is set by service, weight band and zone band, and it is flat for the whole window.

Commercial price increases per package, from the USPS release. Retail increases are listed in the same release and are mostly higher; flat-rate products carry their own increases (Priority Mail large flat rate boxes $1.75, other Priority Mail flat rate products $0.85, Priority Mail Express flat rate envelopes $2.35, commercial).

UPS demand surcharges

UPS publishes its 2026 schedule in its demand surcharges document (August 26, 2026 update) and points shippers at ups.com/peaksurcharge for changes. Like FedEx, it runs three periods, and in Sections A and B the middle one carries the highest amount in every row (the higher-volume bands above 105% do not change with the period); UPS's highest-rate period starts and ends one day earlier than FedEx's. The document notes that demand surcharges apply in addition to all other charges and that the periods may be extended or changed.

Handling, large package and over-maximum charges

Per package, all U.S. domestic shipments (Section A). Periods: September 27 to November 21, 2026; November 22 to December 26, 2026; December 27, 2026 to January 16, 2027.

Per-package demand surcharges

Per package (Section B). Periods: October 25 to November 21, 2026; November 22 to December 26, 2026; December 27, 2026 to January 16, 2027.

The higher-volume shipper tables

For customers billed for more than 20,000 packages in any week after October 2025 (Ground Residential, Ground Saver, Next Day Air Residential and other Air Residential combined), UPS replaces the per-package schedule above with a weekly table: each week's volume as a percentage of the customer's June 2026 baseline (or its August 30 to September 26 volume, if that fell under 80% of June's) sets the amount for every package of that service level that week, and the highest applicable amount applies to all of them. It raises the same question as FedEx's residential charge for a brand shipping on a provider's account: how is a surcharge set by the account's total volume allocated to one client?

Per package by weekly volume band (pages 2 and 3 of the UPS document). The bands above 105% are the same in all three periods; only the 0% to 105% band follows the period, and it equals the standard per-package amount. Next Day Air Commercial and other Air Commercial packages stay at the standard per-package amount in every band.

How 3PLs pass surcharges through

The carrier tables above are the visible part. What a brand actually pays depends on the shipping model in its 3PL agreement, and there are three common ones.

• Cost-plus on the provider's carrier accounts. The 3PL ships on its own negotiated accounts and bills carrier charges at cost, or at cost plus a stated markup. Peak surcharges appear as line items exactly as the carrier assessed them. The upside is transparency; the thing to check is whether account-level charges, like FedEx's residential delivery charge for large shippers, are allocated to you by package, by share of volume, or not at all.
• Blended or all-in rates. The provider quotes one rate per package or per zone that already includes an estimate of surcharges. Peak fees are not itemized, which makes invoices simpler and comparisons harder. Ask whether the blended rate changes during the surcharge windows, and if it does, from which dates.
• Your own carrier accounts. Some providers ship on the brand's accounts, so the surcharges land on your carrier invoice directly and the 3PL charges only for labor and materials. You see everything, and you carry all of it.

On top of any of these, a provider may add a peak handling fee of its own to cover seasonal labor. It is a legitimate charge when it is disclosed before peak; it is a problem when it first appears on a December invoice. Our guide to how 3PL pricing works covers where these fees show up in a quote, and the fuel surcharge calculator covers the other surcharge that moves every week.

What to ask your provider before peak

Six questions, all of which a peak-ready provider can answer in writing in September:

• Which carrier surcharges pass through to my account, at cost or with what markup, and from which dates?
• Do you add a peak handling fee of your own, how much, and for which weeks?
• Which carrier accounts do my orders ship on, and how are account-level charges allocated across clients?
• Will you re-rate orders to a lower-surcharge service or carrier during the windows when the delivery promise allows it, and who decides?
• Which of my SKUs or bundles will trigger additional handling or oversize charges, and can packaging changes before October avoid them?
• Can I see peak surcharges line-itemed on the invoice, or in a report, by carrier and by service?

The same conversation should cover receiving cutoffs, staffing and SLAs; our peak season readiness guide walks through those month by month.

When carrier mix softens the hit

Demand surcharges are not uniform across carriers or services, which is why a provider with a real carrier mix can move the number. Three patterns are visible in the 2026 schedules published so far.

• Light residential parcels. FedEx's per-package demand surcharge on Ground and Home Delivery residential shipments is $0.50 to $0.80, and UPS's on Ground Residential and Ground Saver is $0.50 to $0.75, each layered on the residential delivery charge those packages already carry. USPS's temporary increase on USPS Ground Advantage is set by weight and zone instead, $0.40 to $1.05 at commercial prices for packages up to 10 pounds, with no separate residential fee. A provider that can route light residential orders through USPS Ground Advantage, or through a regional carrier with its own peak terms, has a lever that a single-carrier operation does not.
• Express versus ground. In FedEx's table the per-package demand surcharge on overnight services is $1.30 to $2.55 and on 2Day and Express Saver $1.20 to $2.35, against $0.50 to $0.80 for residential ground; UPS runs $1.35 to $2.50 on Next Day Air and its other air services against $0.50 to $0.75 on Ground Residential and Ground Saver. Orders that ship express by default because that is how the warehouse is set up, rather than because the delivery promise needs it, pay the difference on every package.
• Size and weight. The large FedEx demand surcharges are the Additional Handling ($8.80 to $11.85) and Oversize ($95.75 to $117.25) charges, UPS's are Additional Handling ($8.75 to $11.90) and Large Package ($96.25 to $117.50), and USPS's heaviest band, 26 to 70 pounds, carries its highest increases. Kitting choices, box sizes and whether a bundle ships as one carton or two decide which side of those lines an order lands on, and a provider that flags the SKUs at risk in September is worth more than one that reports the fees in January.
