TL;DR: Every holiday season, parcel carriers add temporary fees to cover the surge in volume between Black Friday and New Year’s. In 2026 those fees are higher than last year across the industry, from the national carriers to the Postal Service. This guide explains what goes into a shipping charge, what the carriers are changing and what supplement brands can do to plan for it. We are writing from the fulfillment side: On Demand Fulfillment (ODF) is a private label supplement fulfillment and dropshipping company that ships 80+ supplements, fully branded, directly to our clients’ customers.


What is a peak season shipping surcharge?

A peak season surcharge is a temporary per-package fee that a carrier adds on top of its base rates during the holiday rush. Carriers use it to pay for the extra labor, sorting capacity and transportation they need when volume spikes. The amount usually depends on the service, the package weight and the distance it travels, and some carriers raise it further in the weeks between Thanksgiving and Christmas.

For supplement brands, these fees land on the orders that matter most, because holiday promotions, gift bundles and subscription renewals all ship in the same window.

What goes into a shipping charge?

A shipping charge is built from several pieces, and only some of them change with the seasons. Understanding each one makes it easier to see why rates move and which parts a brand can actually influence.

Component What drives it When it changes
Base postage Package weight and the distance it travels, which carriers group into zones Usually once a year, when carriers publish new rates
Package size Large, light packages can be priced by their dimensions instead of their weight When packaging changes
Fuel surcharge Fuel prices; DHL eCommerce, for example, adjusts its domestic fuel surcharge monthly based on U.S. diesel prices Monthly
Delivery area surcharge Extra cost to reach certain remote or hard-to-serve ZIP codes Per address
Transportation adjustments Carrier network costs, such as the 8% increase USPS added in April 2026 When the carrier announces one
Peak surcharge Holiday volume Each peak season
Fulfillment Picking, packing and standard packaging at the warehouse Set by your fulfillment partner

DHL eCommerce publishes its current fuel, delivery area and peak surcharges on its surcharge policies page. In October 2026, its domestic fuel surcharge is $0.30 per pound, and packages under 1 lb are charged as 1 lb.

Which carriers are raising rates for the 2026 holiday season?

Peak surcharges are an industry-wide change in 2026. Every major parcel carrier announced holiday fees this year, and most are higher than in 2025. UPS and FedEx raised their residential Ground surcharges by roughly 23% to 25% over last year, per Value Added Resource.

Carrier and service Surcharge window Typical light package Highest-cost window
USPS Ground Advantage (commercial, 0 to 3 lbs) Oct 4 to Jan 17 $0.40 to $0.55 Same all season
DHL eCommerce Parcel Ground and Expedited Max (0 to 3 lbs) Oct 25 to Jan 16 $0.50 $0.90, Nov 22 to Dec 26
UPS Ground Residential Oct 25 to Jan 16 $0.50 $0.75, Nov 22 to Dec 26
FedEx Ground Residential Oct 26 to Jan 17 $0.50 $0.80, Nov 23 to Dec 27

The sections below go deeper on USPS and DHL eCommerce, two carriers that supplement brands and their fulfillment partners commonly use for lightweight e-commerce orders. The same planning principles apply whichever carrier a brand uses.

What is USPS changing for the 2026 holiday season?

USPS added a temporary price increase to Ground Advantage, Priority Mail, Priority Mail Express and Parcel Select that runs from October 4, 2026 until January 17, 2027, according to the USPS announcement. For commercial Ground Advantage, the increase per package looks like this:

Package weight Zones 1 to 4 Zones 5 to 9
0 to 3 lbs +$0.40 +$0.55
4 to 10 lbs +$0.65 +$1.05
11 to 25 lbs +$1.05 +$1.75
26 to 70 lbs +$3.15 +$7.70

Most single and two-bottle supplement orders fall in the 0 to 3 lb tier, so expect $0.40 to $0.55 per package. The holiday increase also stacks on top of the 8% transportation-related increase USPS added in April 2026, which applies to the same services and is also scheduled to end January 17, 2027.

What is DHL eCommerce changing?

DHL eCommerce applies its peak surcharges in three phases from October 25, 2026 through January 16, 2027, as shown in its 2026 peak surcharge table. For packages under 3 lbs going to the contiguous U.S., Parcel Ground and Parcel Expedited Max carry a $0.50 surcharge in the first and last phases, rising to $0.90 from November 22 through December 26. Packages from 4 to 10 lbs carry $0.80, rising to $1.10 in that same middle window.

What happens to shipping rates after peak season ends?

The peak surcharges are scheduled to end in mid-January: January 16, 2027 for DHL eCommerce and January 17, 2027 for USPS. What rates return to after that is up to the carriers. USPS’s April transportation increase expires on the same day, and carriers often publish new annual rates at the start of the year, so brands should not assume shipping costs will go back to early 2026 levels. The safest plan is to budget for the new year’s rates once carriers announce them.

How can supplement brands reduce peak shipping costs?

The math is simple to run. A brand shipping 2,000 single-bottle orders a month pays about $1,100 more at a $0.55 surcharge, which is manageable when it is planned for and painful when a holiday discount has already thinned the margin.

The most effective moves happen before the busiest weeks. Match each order to the right service level, since not every customer needs the fastest option and a few extra days of transit can save real money on gift orders placed early. Look at your offers too: a bundle that ships as one package pays one surcharge, while the same supplements split across two orders pay two. A few other habits help:

  1. Set your free shipping threshold with surcharges in mind, so a holiday discount does not erase the margin on small orders.
  2. Run holiday promotions earlier in November, before the highest-cost weeks.
  3. Publish clear order cutoffs for Christmas delivery so customers order on time.
  4. Review your carrier mix by weight, because the cheapest service for a 4 oz package is not always the cheapest for a 2 lb bundle.

How do fulfillment partners handle peak season surcharges?

If you work with a fulfillment partner, carrier surcharges usually reach you through their shipping rates, but partners handle them in different ways. Some pass each surcharge straight through as a line item. Others build peak costs into a flat rate for the season, absorb part of the increase, or offer several service levels so brands can trade a few days of transit for a lower price.

Before the busiest weeks, it is worth asking your partner a few direct questions:

  1. Which carriers and service levels ship your orders, and can you change them?
  2. Will surcharges appear as separate line items or be built into your rates?
  3. Do your rates change during the highest-cost weeks, or hold steady through the season?
  4. What are the holiday order cutoffs for each service level?

On Demand Fulfillment shares these details directly with its clients, so brands know what to expect before peak volume arrives. Brands planning to launch a private label supplement line can learn more about how shipping works when they get started with ODF.

When should you ship for Christmas delivery?

USPS recommends shipping Ground Advantage by December 17 for delivery by Christmas in the contiguous U.S., and by December 16 for Alaska, Hawaii and U.S. territories. Slower ground services need earlier cutoffs, so check your fulfillment partner’s holiday deadlines for each service level and publish your own customer cutoffs a few days ahead of them.


Frequently asked questions about 2026 peak season shipping surcharges

Are only USPS and DHL raising rates for the holidays? No. Peak surcharges are industry wide, and UPS, FedEx and other carriers announced holiday fees for 2026 as well.

When do 2026 peak season shipping surcharges start and end? USPS peak pricing runs from October 4, 2026 to January 17, 2027. DHL eCommerce surcharges run from October 25, 2026 to January 16, 2027, with the highest rates from November 22 to December 26.

Will shipping rates go back down after January? The peak surcharges are scheduled to end in mid-January, but each carrier decides what its rates return to. Many carriers publish new annual rates at the start of the year, so brands should plan around those announcements.
