Carrier peak charges on home deliveries start this week. Put them next to your promo calendar
UPS started its residential demand charge on October 25 and FedEx starts today. Most of the bill is already set, but when you run your promotions isn't, and for bigger shippers that timing changes the rate.
UPS residential peak demand charges began October 25, 2026 and FedEx's begin October 26; both peak between about November 22 and December 27, and USPS builds its increase into label prices from October 4 to January 17, 2027. Three things are still in your hands: which service each order ships on, how much weekly volume you push above your carrier baseline, and whether parcel dimensions trip handling charges. Lay those against your promo calendar week by week.
What started this weekend
Two dates on the carrier calendar matter more to online stores than the ones around Thanksgiving. According to EasyPost's summary of the 2026 carrier notices, UPS started its residential demand charges on October 25. FedEx starts its own today, October 26. Those are the charges that land on nearly every parcel a direct-to-consumer brand ships, because nearly every one of them goes to a home.
Both carriers then step up again for the busiest stretch: UPS from November 22 to December 26, FedEx from November 23 to December 27. The charges run until mid-January. USPS works differently. Its temporary increase, in effect since October 4, is built into the label price by weight and zone rather than added as a separate line, and it runs through January 17, 2027.
EasyPost's comparison with last year found that the residential demand charges rose the most, roughly 22% to 32% depending on carrier and service. If you budgeted from last year's handling and oversize surcharges, you planned around the charges that rose least.

What you can still change
Most of the bill is already decided. Contract language was set by late September, and the volume baselines that bigger shippers are measured against were calculated earlier in the year. EasyPost names three levers that remain, and they're worth taking in order.
Service mix. The same delivery promise can often ride on a service with a lower demand charge. That's a routing rule in your shipping software, not a contract renegotiation.
Weekly volume against your baseline. This one applies to high-volume shippers. UPS uses a separate tier for shippers above 20,000 packages who ship above their baseline. EasyPost's example: just over 105% of baseline, a ground residential package carries $1.75 instead of $0.50 during the shoulder weeks. FedEx recalculates a dynamic charge every week from your volume, and applies it two weeks later. Just above a 105% peaking factor, a ground package carries $1.70 instead of 80 cents.
Packaging and dimensions. Additional handling and oversize charges hit parcels that cross a size or weight threshold, or whose declared dimensions don't match what the carrier measures. EasyPost calls this the only lever that pays back inside a week.
The second lever is where marketing comes in. If Black Friday, Cyber Monday and a mid-December flash sale all spike volume in the same weeks, that spike can push you into a higher tier. Your promo calendar is now a shipping rate decision, whether marketing knows it or not.

The calendar, week by week
Treat this as a working template. The dates come from the carrier notices as summarized above; the actions are ours.
This week (October 26 to November 1). Pull last year's weekly parcel counts by carrier and service and put them next to this year's promo calendar. If you're a high-volume UPS or FedEx shipper, ask your carrier rep or shipping platform for your baseline figure in writing. Then flag every week where planned volume looks more than 5% above it.
Early November (November 2 to 15). Fix the packaging problems. List your top-selling items that sit near a size or weight threshold and check their dimensions in your product data against a tape measure. A box one inch smaller can move a parcel out of a handling charge for the rest of the season.
The shoulder week (November 16 to 21). This is the last week before the highest rates at both carriers. If you can pull an early-access sale or a loyalty preview into it, that volume ships at shoulder rates. Remember that FedEx's dynamic charge applies two weeks after the week it's calculated on, so a big week now shows up on later labels.
Peak (November 22 to December 27). Check your routing rules every Monday. If one carrier's tier has jumped for you, shift the orders that can move to another carrier or service without breaking the delivery promise.
Cutoff week (December 14 to 19). USPS lists December 17 for Ground Advantage, December 18 for Priority Mail and December 19 for Priority Mail Express as the last recommended days to ship for delivery by Christmas. Put the right date on product pages and checkout per shipping method, and switch it off the day after.
January. The charges run until January 16 at UPS and January 17 at FedEx and USPS, which covers most holiday returns. Your returns policy and label choices still matter for the first two weeks of the year.
How the work moves
Three levers, in order
- Measure
Last year's weekly parcels next to this year's promos.
- Flag
Weeks planned above 105% of your baseline.
- Move
Pull a promo into the shoulder week if possible.
- Route
Shift eligible orders to a lower-charge service.
- Resize
Fix boxes near handling thresholds.
Who owns which piece
The work splits along lines most stores already have, which is why it slips. Marketing owns the promo dates. Operations owns carrier accounts and routing rules. Whoever manages the catalog owns the dimensions. Nobody owns the place where all three meet.
For the next eight weeks, name one person who sees all three each Monday: the volume forecast, the routing rules and any packaging fixes still open. It's a short meeting, but someone has to run it.
Bring three numbers to it: last week's parcels by carrier and service, next week's forecast against your baseline, and the count of orders that shipped on a more expensive service than they needed. The third number is usually the easiest to fix, because it comes from a rule someone wrote years ago and never revisited. A default that sends every order over a certain value by an express service, for example, may have made sense once and costs much more in December.
If marketplace orders ship on the same carrier accounts as your own store, include them too. They count toward the same weekly volume.
What not to do
Don't cut free shipping in a panic in the second week of December. Customers notice, and by then most of the surcharge bill is already set. Don't promise delivery dates the carriers haven't promised you. And don't move every order to the cheapest service without checking its transit time against the ship-by dates. Saving money on shipping doesn't help if the gift arrives on December 27.
