The Euro pallet measures 1200 × 800 mm and is certified by the EPAL association. A standard 13.6 m semi-trailer takes 33 of them unstacked, in two rows across, and each one occupies 0.4 loading metres.
In groupage many operators price per pallet, and the exchange of empty pallets is a classic source of disputes. Write on the consignment note how many you hand over and how many you get back.
