What is a ULD?
ULD stands for ‘unit load device’. It’s a container used to safely transport large quantities of freight.
A ULD is often called a cage.
How much can you load on a ULD?
The total weight of parcels in an Australia Post ULD needs to be under 600kg, including the weight of the ULD itself.
How do you label a ULD?
Use an Australia Post VISA label on the ULDs you’re sending: white for standard sending and yellow for Express Post.
Labels need to be put on two sides of the ULD.
You’ll need to fill in the required information on each label, including the destination, contents and gross weight.
Where do you get the labels for ULDs?
You can order the VISA labels from your lodgement point.
How do you know what your ULD responsibilities are?
There are some legal and safety requirements to follow for the safe assembly, use, storage & transport of ULDs. For example, it’s important to make sure they are stacked correctly and the product is always below the top of the ULD, evenly spaced & balanced within to eliminate damage to your freight whilst in transit.
Follow our Chain of Responsibility to make sure you’re sending ULDs correctly.
