# 4.5.5 Prefer Unitload

In actual loading operation, sometimes it is required to generate a unitload (pallets, boxes) first, and then mix and load the rest of the goods .

You should check the \[Prefer unit load], and set the \[Minimum volume usage rate required for unit load]. As long as the volume usage rate of the container can reach the \[Minimum volume usage rate required for unit load], the unitload (pallet, box) will be preferentially generated, and then the remaining cargoes will be mixed and loaded. If the container does not reach the \[Minimum volume usage rate required for unit load], no unitload will be generated, and the cargoes will be mixed and loaded according to the default algorithm. For specific operation methods, you can see the application cases below.
