ULD (Unit Load Device)

What is a ULD?

A ULD (unit load device) is a device used to move cargo being shipped as airfreight. More specifically, a ULD is used to consolidate cargo in order to assist with the loading process onto an airplane.

ULDs come in two forms: pallets and containers.

Netted cargo pallets staged on an airport tarmac beside a WGA cargo Boeing 747, with DHL aircraft in the background.

Pallets

An empty aluminum air cargo container (ULD) with an open front, metal floor and walls, and a documentation pouch on the side panel

How will air cargo be consolidated?

Air cargo can be tendered loose to an airline, and the airline will load the air shipment into a ULD with other shipments.

Shippers can also book a ULD container and load the ULD themselves. Then a trucker at destination can pick up the entire ULD and deliver it to a warehouse to be deconsolidated.
