Most carrier surcharges cost a few dollars. This one costs more than a thousand. The excess fee — UPS calls it “Over Maximum Limits,” FedEx calls it the “Unauthorized Package” charge — reached $1.875 per package in 2026, up from $1,325 in 2025. That represents a 41% increase in a single year, and is the largest single line item most shippers will ever see on a parcel invoice.
The worst part is how easy it is to trigger. One box that’s an inch too long, or a pallet-sized carton that a worker assumed was «probably fine,» and a $90 shipment becomes a $1,965 shipment. There is no partial credit and no sliding scale: the package either meets the limits or it does not.
Here is exactly where the lines are drawn in 2026, what has changed this year, and how to keep oversized freight out of the parcel network in the first place.
What triggers the fee for exceeding the maximum limits?
Both UPS and FedEx charge a fee when a package exceeds anyone of three thresholds. You don't have to exceed all three.
- Actual weight over 150 lbs — 151 lbs is over the limit.
- Length over 108 inches — measured only along the longest side.
- Length plus girth greater than 165 inches — where girth is 2 × width + 2 × height.
That third measurement is the one that trips people up. A box that is 80 inches long but 25 inches on each side adds up to 80 + (2 × 25) + (2 × 25) = 180 inches. Nothing about it looks extreme, and it exceeds the limit by 15 inches.
Carriers measure the packed box, not the product. Padding, double-boxing, and a bulging side all count. A carton that bulges outward during transit can be remeasured at a sorting hub and billed days after it was handed over.
The 2026 Escalation Ladder
The over-limit fee is the top rung of a three-step ladder. Each step has its own thresholds, and knowing where you stand tells you how much wiggle room you have left.
| Overload | Triggers (any one) | Typical Cost in 2026 |
|---|---|---|
| Additional Handling (Dimensional) | Cubic volume greater than 10,368 cu in; long or irregularly shaped packaging | Approximately $30–$50 per package |
| Large Package / Oversized | Longest side over 96 in; length plus girth over 130 in; cubic volume over 17,280 cu in; actual weight over 110 lbs | $219.50–$331.00, depending on zone and residential status |
| Exceeding Maximum Limits / Unauthorized Package | Weight over 150 lbs; length over 108 in; length plus girth over 165 in | $1.875 per package |
The rates shown are published list prices and are for reference only—your actual cost depends on your carrier agreement, service level, zone, and any negotiated surcharge caps.
Two details in that middle row are more important than they appear. Large Package shipments carry a Minimum billable weight of 90 lb, so a 40-lb oversized box is billed as if it weighed 90. And when the Large Package Surcharge applies, the Additional Handling fee is not charged on top — the surcharges do not stack at that stage.
What changed in 2026: cubic volume became a trigger
This is the change that caught many shippers off guard midway through the year. In January 2026, both carriers added cubic volume as a standalone trigger for dimensional surcharges. Previously, oversize assessments were based on length and length plus girth. Now, a package is also measured based on its total volume.
FedEx announced the expanded assessment on January 12, 2026. UPS followed later that same month. The thresholds are the same for both carriers:
- Over 10,368 cubic inches → additional handling due to size
- Over 17,280 cubic inches or more 110 lbs → oversized / large package
Cubic volume is simply length × width × height in inches. To visualize 10,368 cubic inches: a 24″ × 24″ × 18″ box is exactly 10,368 cubic inches. That is a standard-looking cardboard box that many shippers use daily and that previously passed through without any dimensional surcharge at all.
The practical consequence is that Light, bulky freight is now detected earlier. Furniture parts, pet crates, bicycle boxes, planters, "mattress-in-a-box" products, and display fixtures all moved up a notch without changing anything about how they are packed.
The math behind the decision between parcel and freight
Once a shipment is close to 150 lbs or 165 inches in total, parcel shipping is no longer the cheapest option. Compare the options before you print the label, not after.
| Shipment | Parcel Outcome | Better route |
|---|---|---|
| One 160-pound crate | Base rate + $1.875 over the maximum fee | LTL freight on a pallet |
| 112" long tube, 45 lbs | Base rate + $1.875 (length over 108″) | LTL, or cut into two 56-inch tubes |
| Three 55-pound boxes, same address | 3 × base rate, no oversize fees | Hundredweight / Multiweight Pricing |
| 26″ × 26″ × 20″ cardboard, 60 lbs | Base rate + large package surcharge, minimum billable weight of 90 lb | Redesign carton under 17,280 cu in |
Splitting one over-limit package into two compliant ones is almost always cheaper than paying the fee—two base rates plus two large package surcharges still come to well under $1,875. The limits apply per package, not per shipment.
Seven Ways to Stay Under the Limit
- Measure the packaged box, not the product. Tape, corner protectors, and void fill all add inches.
- Calculate the length and girth for every SKU longer than 60 inches. Incorporate it into your product data so that it is checked only once, rather than for each order.
- Add cubic volume to your packaging audit. Any box larger than 24″ × 24″ × 18″ now warrants a second look.
- Use rigid boxes, not soft bags, for anything heavy. Bags change shape and are remeasured to a larger size.
- Take a photo of your measurements — Make sure the tape measure is visible at the start and end of the run — so you have proof to challenge a remeasurement.
- Set a hard system block At 145 lbs and 160 inches combined, so nothing close to the limit can print a shipping label without a manual override.
- Price in LTL (in parallel) for anything over 110 lbs. A single pallet is often more cost-effective than a single oversized package, even before surcharges are applied.
If you have already been billed
A charge for exceeding maximum limits is disputable when the carrier’s measurement is incorrect—and remeasurements are not infallible. Retrieve the shipment record, compare the billed dimensions with your own documented measurements, and file a dispute within the carrier’s specified timeframe. Shippers who routinely audit invoices catch these issues; those who do not end up paying them.
Also check whether the package was delivered. FedEx reserves the right to reject, return, or dispose of unauthorized packages entirely. If the package is returned to you, you may be responsible for the fee plus return shipping costs for a shipment that never reached the customer.
The bottom line
At $1,875 per package, the fee for exceeding maximum limits is not a cost of doing business—it is a packaging failure with a price tag. The thresholds have not changed in years: 150 lbs, 108 inches, and 165 inches combined. What changed in 2026 is that cubic volume now pushes ordinary-looking boxes into the surcharge brackets sooner, which means the gap between «fine» and «catastrophic» is narrower than it used to be.
Measure once, using the packed box as a reference, and send anything close to the limits as freight. It takes a minute and is worth $1,875.
