The next peak surcharge date on the 2026 calendar does not belong to a national carrier. It belongs to OnTrac, the regional carrier plenty of DTC brands added for the specific purpose of keeping peak costs down.
OnTrac's published surcharge schedule puts its peak demand surcharges in effect from September 26, 2026 through January 15, 2027. That first date is 19 days away.
The fees that start first are about your box, not your customer
The start dates are not uniform, and the split is the interesting part.
Four demand surcharges begin September 26:
- Demand Additional Handling: $11.00 per package
- Demand Large Package: $110.00 per package
- Demand Over Max Limits: $595.00 per package
- Demand Unauthorized: $595.00 per package
One waits until October 24:
- Demand Residential: $1.00 per package
The residential fee is the one that touches nearly every DTC order, and it is the one OnTrac holds back for another month. The fees landing first are all triggered by dimensions or by packaging that falls outside spec.
Read that ordering as a signal. OnTrac is pricing the cost of handling awkward freight through peak, well before it prices the cost of driving to houses. If you ship apparel or supplements in poly mailers, September 26 will not show up on your invoice. If you ship anything bulky, or anything in a carton that trips additional handling, September 26 is the date your unit economics change.
The gap between those two categories is large. Eleven dollars on an additional handling package is a rounding error next to $110 on a large package. Brands that have never checked which of their SKUs cross those thresholds are about to find out by invoice.
Diversifying carriers does not dodge peak fees this year
The old play was straightforward. Peak surcharges landed hardest on the national carriers, so brands moved volume to a regional network and kept some margin. That play does not work the same way in 2026.
Transportation Insight's weekly industry summary, published September 2, made the point directly: alignment across carriers on peak surcharges removes the option of shifting volume to avoid them. Its recommendation was to build the surcharge schedules into fourth quarter cost models now rather than after invoices reflect them, and to review contract terms for surcharge caps or negotiated exceptions before the September effective dates arrive.
That matches what the rest of the calendar looks like. UPS, FedEx, USPS, and Amazon Shipping have all posted 2026 peak schedules, and we walked through how they stack in the 2026 peak fee breakdown. Adding a fifth carrier to the mix now gets you capacity. It does not get you an exemption.
So the lever worth pulling is not carrier selection. It is package characteristics, and that is a lever you actually control.
What this means for your brand
If you ship 1,000 to 25,000 orders a month, here is the work worth doing in the next two weeks.
- Pull your dimensions on your top 20 SKUs by volume. Measure the shipped carton, not the product box. Girth and longest side are what trigger the large package charges.
- Find the packages already paying additional handling. They are on your current invoices, off-peak, at the year-round rate. Anything on that list gets more expensive on September 26.
- Read the surcharge language in your carrier agreement. Caps and exceptions exist, but they only help if someone asks before the window opens.
- Rebuild the Q4 landed cost model with peak numbers in it. Not base rates. Peak rates, by week, since several carriers step their fees up further from late November.
The brands that get hurt here are the ones treating every order as one average shipping cost. Peak surcharges are not average. They concentrate on a small share of your order profile, and that share is knowable right now.
Some of this is fixable with packaging work rather than pricing changes. A carton that measures a half inch under a threshold ships at a different price than one a half inch over. Consolidating a two-box order into one properly sized carton can remove a surcharge entirely. That is kitting and packing work, and it pays for itself fastest during the exact window that starts this month.
It also matters where the boxes ship from. Moby Dick runs out of Canal Winchester in the Columbus metro, which puts 60% of the US and Canadian population inside 600 miles and reaches 90% of customers in two days by ground. Shorter zones mean fewer packages riding long distances at peak rates. If your current setup is sending bulky items across the country to reach the Midwest and East, the zone math is working against you before any surcharge applies.
If you want a second set of eyes on which of your SKUs are about to cross a threshold, get in touch. That review takes an afternoon and it is worth doing before September 26, not after.
FAQ
Does the OnTrac peak surcharge apply to every package?
No. The four surcharges starting September 26 apply to packages that trigger additional handling, large package, over max limits, or unauthorized package criteria. The $1.00 residential demand surcharge is broader, and it does not start until October 24 per OnTrac's published schedule.
How long do the 2026 OnTrac peak surcharges last?
OnTrac lists the peak demand surcharge period as September 26, 2026 through January 15, 2027.
Should we switch carriers to avoid peak surcharges?
Switching now is unlikely to help on fees. Every major network has published a 2026 peak schedule, so a new carrier mostly buys capacity rather than savings. Reducing the number of packages that trigger dimension-based surcharges is the more reliable path.
What is the deadline to act?
September 26 for anything bulky moving on OnTrac. Contract conversations should happen sooner, since carrier partners generally see the market tightening through October and into the holiday weeks.
