What is a pallet-wide container?

A EUR pallet is 1,200 × 800 mm. A standard container is 2.352 m wide inside, and neither side of the pallet divides into that: two pallets set with the 1.2 m side across need 2.4 m, which is 48 mm more than there is. So loaders mix orientations — one band lengthwise, one turned — and a 40 ft takes 25 pallets with a strip of floor left over along one wall.

The pallet-wide box thins its side walls and grows slightly on the outside, to about 2.50 m, which brings the interior to roughly 2.44 m. Now 2.4 m of pallets fits either way: two bands with the 1.2 m side across, or three bands with the 0.8 m side across. On the floor of a 40 ft that makes 30 pallets and on a 45 ft it makes 33 — the count of a European road trailer, which is the point: a truckload moves to a ship or a train with no pallet left behind. The width arithmetic is worked through in pallets in a 40 ft container.

You meet the term in quotes from European short-sea, ferry and rail operators, written as “45 ft PW”, “45 HC PW” or “pallet-wide high cube”. Those operators run the boxes between European ports and inland terminals. On deep-sea services they are rare, because the wider body does not sit in the cell guides of a standard container ship, which are spaced for the 2.438 m ISO width.

When a quote says PW, ask the operator for the internal width and the door opening of the actual equipment. ISO 668 does not fix this size and builders differ by a few millimetres, so treat 2.44 m as a round figure, not a specification. The pallet footprints themselves are in the pallet sizes guide.

The usual mistake is to read “45 ft” and assume 33. A standard ISO 45 ft high cube has the same 2.352 m interior width as every other deep-sea box and holds 27 EUR pallets on the floor; only the pallet-wide 45 holds 33. The same goes for the 40 ft: 25 standard, 30 pallet-wide. If the load plan was drawn for the wide box and a standard one backs up to the dock, five or six pallets stay in the warehouse and need a second booking.

The reverse error costs too: booking pallet-wide equipment for a route that ends with an ocean leg. Check that every carrier on the route accepts it before the pallets are wrapped. And remember whose pallet the box was drawn around — the gain belongs to the 1,200 and 800 mm sides of the EUR pallet, and cargo on other formats or in loose cartons may gain almost nothing from the extra width.
