2026 Peak Season Surcharges: What Canadian Sellers Need to Know

Peak season brings higher volumes and added carrier costs. As Q4 approaches, carriers often introduce temporary surcharges across select services and shipment types. For 2026, some carriers have started releasing their peak-season pricing, with more announcements expected in the coming weeks.

These surcharges vary by carrier, service, destination, weight, and package size, and may apply to domestic, US, or international shipments. We will continue updating this page as new peak-season surcharge information becomes available.

Note: Rates, currencies, effective dates, and applicable services vary by carrier.

2026 Carrier Peak Season Surcharges

Below is the latest peak-season surcharge information announced by carriers.

USPS Peak Season Surcharges

The United States Postal Service (USPS) is applying temporary rate increases from 12:00 a.m. CT on October 4, 2026, to 12:00 a.m. CT on January 17, 2027.

The increases apply to four services only: Priority Mail, Priority Mail Express, USPS Ground Advantage, and Parcel Select. No other USPS products are affected. These increases are added to current rates, which already include the Fuel Surcharge increase from April.

USPS Ground Advantage

Priority Mail

Priority Mail Express

Parcel Select

A few of these increases overlap. For Zones 1 to 4, Priority Mail and USPS Ground Advantage share the same increase at each weight tier:

• 0 to 3 lbs and Cubic Tiers 1 to 3 at +$0.40
• 4 to 10 lbs and Cubic Tiers 4 to 5 (Priority Mail) or 4 to 9 (Ground Advantage) at +$0.65
• 11 to 25 lbs and Cubic Tier 10 (Ground Advantage) at +$1.05
• 26 to 70 lbs and Oversized at +$3.15

UPS Peak Season Surcharges

UPS’s peak window runs from September 27, 2026, to January 16, 2027. It’s longer than the USPS window and starts a week earlier. Unlike USPS, UPS breaks its surcharges into three date periods within that window, with the highest rates landing in the Black Friday through Christmas stretch.

Additional Handling and Large Package

These apply to all package services and are charged per package.

Demand Surcharge

Demand Surcharge amounts vary by service, and for some services, by volume. UPS Ground Residential and UPS Ground Saver, UPS Air Residential, and UPS Air Commercial each fall in a range from October 25 to January 16:

• UPS Ground Residential and UPS Ground Saver: $0.50 to $8.00
• UPS Air Residential: $1.35 to $9.35
• UPS Air Commercial: $1.35 to $2.50

For UPS Ground Saver, UPS Ground Residential, and UPS Domestic Air, there’s also a per-package Demand Surcharge that steps up during the peak weeks:

Additional Handling, Large Package, and Demand Surcharges are subject to qualifying volume criteria, so the exact amount you’re charged depends on your shipping volume with UPS.

Other Peak Season Surcharges

These run for the full peak window, September 27, 2026, to January 16, 2027:

DHL Peak Season Surcharge

DHL Demand Surcharges will apply from October 1, 2026, to February 5, 2027, during the busy shipping season. Rates vary by destination and billing weight and are charged in USD per lb. Fuel surcharge also applies.

The charges above apply to DHL Express Worldwide, DHL Express 12:00, DHL Express 10:30, DHL Express 9:00, DHL Express Envelope, DHL Express Breakbulk, including the respective import and 3rd Country equivalents

What This Means for Your Shipping Costs

These surcharges are per package and get added on top of your existing base rates, regardless of which carrier is handling the shipment.

For a business shipping hundreds of thousands of packages during Q4, even a $0.50 to $1 increase per package adds up fast, and the larger flat surcharges can be significant if any of your products fall into those size or weight categories.

A few things worth doing now, before the peak window opens:

• Check your package dimensions and weights against the surcharge tiers. If any of your products are borderline for Large Package or Oversized classifications, repackaging to bring them under the threshold could save a meaningful amount over the season.
  
  
• Review which carrier and service level make sense for each shipment. Surcharges vary by carrier service and the date period, so the cheapest option earlier in the season may not be the cheapest option during the busiest weeks. If you have flexibility in when orders ship, spreading volume outside that window can reduce costs.
  
  
• Build the increases into your Q4 pricing and margins now. Since these are temporary rate adjustments layered on top of standard pricing, they won’t show up as a permanent rate hike, but they will affect your shipping cost per order for the entire fourth quarter.
  
  
• Watch for additional carrier updates. More carriers are expected to release their 2026 peak season pricing. Stallion will update this post as that happens. In the meantime, see our 2026 U.S. tariff updates to know more about tariffs, duties, and taxes for your US-bound shipments.

Final Thoughts

Peak season surcharges are a regular part of holiday shipping, but the details change each year by carrier, service, destination, and shipment type. The rates in this post reflect the latest 2026 announcements available so far. We will continue updating this page as more carriers release their peak season pricing.
