Unit Load Devices & Intermediate Bulk Containers

A unit load device (ULD) is any type of freight container, aircraft container, aircraft pallet with a net, or aircraft pallet with a net over an igloo. Overpacks and freight containers for radioactive material are not included in the definition of a unit load device.

Each ULD containing dangerous goods that require hazard labels must clearly display on its exterior an indication that dangerous goods are contained. A ULD identification tag has prominent red hatchings on both sides. The primary and subsidiary hazard class and division must be marked on the tag. If the ULD contains a CAO label, that information must be included on the tag. The tag must be removed from the ULD when the dangerous goods are removed.

The only dangerous goods permitted for transport in an IBC are UN 3077, Environmentally hazardous substances, solid, n.o.s. IBCs must be marked with appropriate handling labels. The markings must indicate the maximum stacking weight or the IBC cannot be stacked.
