Peak-season freight cost pressure is moving from forecast to invoice. UPS, FedEx and USPS have published holiday price programs that begin in late September or early October, while ocean, air and inland freight indicators point to tighter capacity heading into Q4.
UPS says demand surcharges for U.S. domestic packages requiring Additional Handling, Large Package treatment or Over Maximum Limits start Sept. 27, 2026 and run through Jan. 16, 2027. The largest UPS domestic size-based window runs from Nov. 22 through Dec. 26, when the published demand surcharge reaches $11.90 per package for Additional Handling, $117.50 for Large Package and $590 for Over Maximum Limits.
UPS also starts demand surcharges for UPS Ground Saver, UPS Ground Residential and UPS Air packages on Oct. 25. For the Nov. 22 to Dec. 26 peak window, published UPS Ground Saver and Ground Residential demand charges are $0.75 per package, while UPS Next Day Air and other UPS Air services are listed at $2.50 per package before higher-volume shipper rules are considered.
FedEx has a similar early start. FedEx lists Demand Additional Handling, Demand Oversize and Demand Unauthorized charges beginning Sept. 28, with the highest FedEx U.S. package amounts running Nov. 23 through Dec. 27. In that core window, FedEx lists $11.85 per package for Additional Handling, $117.25 for Oversize and $595 for Unauthorized packages. FedEx residential, express and Ground Economy demand surcharges begin Oct. 26, with the highest listed window also running Nov. 23 through Dec. 27.
USPS has also posted final time-limited 2026 price files for Oct. 4, 2026 through Jan. 17, 2027. The temporary price change affects Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select, with increases varying by service, zone, weight and retail or commercial price category.

Weekly updates
Fuel surcharges remain a moving cost line; for Sept. 21-27, Canada Post lists 44.50% for domestic parcel services, 25.50% for USA and international parcel services, and 23.50% for USA and international packet services.
Carrier pages still need monitoring before shipments are tendered. UPS says demand periods may be extended or otherwise changed, and FedEx says it can reassess or reinstate demand surcharges at its discretion.
Ocean freight is not easing evenly
The National Retail Federation and Hackett Associates said Sept. 9 that this year’s extended import peak was still running later than expected. NRF Vice President Jonathan Gold said, “We thought the peak season would be mostly behind us by now, but that’s not the case.”
Global Port Tracker forecast September at 2.31 million TEU, up 9.6% year over year and slightly ahead of July as the expected busiest month of 2026 for the U.S. ports covered by the report. October was forecast to fall to 2.11 million TEU, while still remaining up 1.7% year over year.
Drewry’s World Container Index for Sept. 17 rose 1% to $4,500 per 40-foot container. The transpacific lane showed more pressure than the headline number: Drewry said Shanghai-to-Los Angeles rates rose 5% to $7,712 per 40-foot container, while Shanghai-to-New York rose 7% to $10,394.
Capacity management is part of the picture. Drewry’s cancelled sailings tracker for Sept. 18 said 77 blank sailings were expected from week 39 through week 43, covering Sept. 21 through Oct. 25, out of 720 planned sailings. That represented an 11% cancellation rate, with 55% of the disruptions concentrated on the transpacific eastbound trade.
Air and inland networks are carrying pressure too
Air cargo is also showing a demand-and-capacity mismatch in North America. IATA said global air cargo demand rose 3.9% year over year in July 2026, while global capacity rose 1.7%. For North American carriers, demand rose 4.8% year over year, while capacity fell 1.5% and the cargo load factor reached 41.2%.
Fuel adds another variable. IATA said jet fuel prices rose 12.2% month over month in July and were 56.9% higher than a year earlier. That does not automatically translate into a single surcharge outcome across every carrier, but it keeps fuel and demand charges high on the invoice-audit list.
Maersk’s September North America market update described domestic ground freight as entering a tighter and more selective phase. The update said truckload volumes had declined over the summer while rates kept climbing, and that capacity, carrier selectivity and driver-qualification enforcement were keeping upward pressure on LTL pricing.
Where ecommerce and physical-goods firms still have room to act
The immediate risk is not only that peak fees exist. It is that many fees are triggered by shipment characteristics that can still be changed: box size, dimensional weight, fulfilment node, service level, residential delivery mix, carrier allocation and timing.
Oversized and hard-to-handle items need early margin review. UPS and FedEx both place the largest published parcel demand charges on packages that trigger handling, size or maximum-limit rules.
Carrier routing should be set by SKU, zone and date. A single default carrier rule can hide the difference between a normal residential surcharge and a peak-week service surcharge.
Inventory timing still matters. Ocean capacity controls and blank sailings can make late replenishment more expensive, less reliable or both, especially around Golden Week and the transpacific peak.
Air freight should be reserved for true priority stock. IATA’s July numbers show demand growth outpacing capacity growth globally, with North America showing demand growth alongside lower capacity.
Fuel and accessorial charges need weekly review. Canada Post’s weekly fuel surcharge model shows how quickly the non-base-rate portion of shipping can change.
Average shipping costs will miss the real exposure
Q4 freight planning based on average order cost is too blunt for this surcharge cycle. The more useful model breaks shipments by billed weight, dimensions, residential or commercial delivery, zone, carrier, service level, fulfilment location and ship week.
Free-shipping thresholds and earlier holiday cutoffs are two remaining commercial levers. Once inventory arrives late, boxes are packed, labels are automated and holiday promises are live, surcharge mitigation becomes customer-service triage instead of a margin decision.
