Forty inches is not a big box. It is a framed poster, a shelf board, a rolled rug, and it is the point where DHL Express stops treating a piece as ordinary. The second longest side has a line of its own at 32 inches. Both are measured per piece rather than per shipment, so a pallet of four awkward cartons collects the charge four times.
Two sides decide the oversize charge and a third number decides whether the piece is accepted at all.
The trigger fits in a single sentence on DHL's US surcharge listing. A fixed charge lands on “every piece, including a pallet, if its longest side exceeds 100 cm (40 in.) or its second longest side exceeds 80 cm (32 in.) for shipments originating in the U.S. and U.S. Territories”. The listing carries an update stamp of July 20 2026 and an effective date of August 3 2026, and was read on 2026-07-31.
Readers skip past two things in it. The first is the second longest side. A long thin tube clears 32 inches easily on width and height, but a squarish carton 42 inches across the base is over on both counts, and there is no partial version of the charge. The second is every piece. Consolidating five oversize cartons onto one waybill does not consolidate the charge; it multiplies it, and a pallet counts as a piece in its own right.
| Charge | What sets it off | How it interacts |
|---|---|---|
| Oversize Piece | Longest side over 100 cm (40 in.), or second longest side over 80 cm (32 in.) | Not applied to a piece that is already carrying the overweight charge |
| Overweight Piece | Scale or volumetric weight over 150 lbs. | Charged per piece, a pallet included |
| Non-Conveyable Piece | Actual weight between 56 lbs and 150 lbs on an export, or packaging a belt cannot carry: shrink wrap, drums and tires, wheels, handles, straps, foam, wood, metal, an unboxed item | Not applied to a piece already carrying the oversize or overweight charge |
| Non-Stackable Pallet | A pallet that cannot be stacked, either because the shipper asks for it or because of its shape, contents or packaging | May be added on top of the other three; not applied to pallets under 25 kg |
The guide puts the fuel surcharge on the weight charge of the shipment and on any transportation-related surcharges, so the per-piece amounts are not the last word on what an awkward carton adds to the bill.
Past the charges sit the acceptance ceilings, and those are the numbers that settle whether a box moves at all. The rate guide states them flatly on every rate page: “DHL Express does not accept shipments exceeding 6,600 lb, or containing pieces exceeding 2,200 lb or 118 inches length, or not meeting DHL standards for packing.” The 2,200 lb figure belongs to a palletized piece; a loose carton is capped far lower.
| Ceiling | DHL Express Worldwide | DHL Express 12:00 | DHL Express 9:00 (10:30 to the USA) |
|---|---|---|---|
| Heaviest loose piece | 150 lb | 150 lb | 56 lb |
| Pieces per shipment | None stated | 10 | 10 |
| Heaviest pallet | 2,200 lb | Pallets not accepted | Pallets not accepted |
| Largest pallet, L x W x H | 118 x 78 x 63 in | Pallets not accepted | Pallets not accepted |
| Heaviest shipment | 6,600 lb | 660 lb | 560 lb |
| Countries and territories served | More than 220 | 151 | 85 |
The row that is not in the guide is worth as much as the ones that are. Against maximum piece dimensions the guide prints a footnote rather than a number, and the footnote says a shipment is unacceptable if its packaging is absent or inadequate, or if carrying it would risk damaging equipment or other packages or injuring staff, with DHL reserving the right to refuse it or send it back. So outside the 118 inch length cap there is no published width and height box for a loose piece, only a judgment made at the counter. The guide adds that these network restrictions can change on 30 days notice.
One more thing sits behind that 150 lb loose piece line: above 150 lbs the guide stops using its weight table and prices the shipment by multiplying total weight by a per-pound zone multiplier. Crossing it changes how the rate is built, not only what it comes to.
The overweight trigger reads “a scale or volumetric weight of 150 lbs.”, which means a carton never has to be heavy to earn it. DHL Express turns volume into weight by dividing centimeters by 5,000, so anything past about 20,800 cubic inches is over the line whatever the scale says. That is a carton around 44 by 30 by 16 inches, a size a flat-packed dresser or a set of shelf panels reaches without effort.
Because the oversize charge steps aside for a piece that is already overweight, a very large carton pays the heavier of the two rather than both. The practical consequence runs the other way from what people expect: splitting one enormous carton into two merely oversize ones can cost more, not less, since each of the two carries its own oversize charge. Work the volume out before deciding how to divide the load. Our DHL volumetric weight page has the divisor and a calculator that takes inches.
DHL Express sells international movement from the United States, and our checkout prices US domestic parcels. For anyone whose oversize box is not leaving the country, the DHL thresholds are still a useful ruler, because they mark sizes worth knowing about. We ran four cartons straddling those lines through the SMKlog calculator to see what the domestic side made of them.
| Carton | Longest / second longest | Where DHL puts it | Cheapest US domestic price |
|---|---|---|---|
| Framed poster, flat carton 39 x 31 x 4 in, 12 lb | 39 in / 31 in | Under both lines | $71.91 UPS Ground |
| Framed poster, flat carton 43 x 33 x 4 in, 14 lb | 43 in / 33 in | Over on both sides | $71.91 UPS Ground |
| Desk top panel, flat carton 48 x 28 x 6 in, 30 lb | 48 in / 28 in | Over on length alone | $83.55 UPS Ground |
| Flat-packed dresser panels 44 x 30 x 16 in, 55 lb | 44 in / 30 in | Overweight on volume, so the oversize charge drops away | $217.31 UPS Ground |
The first two rows are the same poster in two different frames. Four inches of extra length and two of extra width carry the second carton across both DHL lines, and on the domestic side the two landed on the identical price. Whichever ruler applies to a box, an inch either side of a threshold is never worth the risk of guessing at it.
The fourth row is a cliff of a different kind. Its volumetric weight works out near 153 lb on the DHL divisor, arithmetic done here from the dimensions shown, which puts it past the 150 lbs overweight trigger while the scale reads 55 lb. Domestic carriers keep an oversize tier of their own, and it caught the same carton. Its cheapest checkout price on the day was $217.31, against $83.55 for the 48 x 28 x 6 in panel — a longer carton, but a far shallower one. Both are cheapest checkout prices on the same lane and the same date. How the domestic large package charge works covers that side.
DHL revises its surcharge listing on its own schedule and applies different thresholds to shipments originating outside the United States, where the same two charges are written as 100 cm and 80 cm on the sides and 70 kg on the weight. Check the listing against the country the shipment actually leaves from.
For a shipment leaving the U.S., a piece is oversize once its longest side passes 100 cm (40 in.) or its second longest side passes 80 cm (32 in.). The charge lands on each piece separately, a pallet included, and DHL publishes the amount on its US surcharge listing.
No piece may exceed 118 inches in length, no loose piece may exceed 150 lb, a pallet may reach 2,200 lb inside 118 by 78 by 63 inches, and a whole shipment stops at 6,600 lb. Those ceilings come from the DHL Express Service and Rate Guide 2026 for the United States.
Yes. The overweight charge reads whichever is greater of the scale weight and the volumetric weight, so a roomy carton of foam, bedding or empty packaging crosses 150 lbs on volume long before the scale gets anywhere near it.
No. DHL states that the oversize charge is not applied to a piece already carrying the overweight charge, and that the non-conveyable charge is not applied to a piece carrying either of them. A non-stackable pallet charge can still be added on top.
No. The carriers our checkout returns for a US domestic parcel are UPS, FedEx and USPS. This page is here because the piece limits decide whether an awkward box travels on a DHL waybill at all, and they sit scattered across two documents.
