I have found some useful postings on handling unit.
But I still like to further clarify or confirm my understanding is correct.
Simply put :
A handling unit is a container truck. Correct?
I also like to confirm the following:
1. these are packaging materials : Carton, Pallet and container.
2. A handling unit can consist of other handling units. But what is an example of this? Could someone give me a clearer example? Is it a Container ship containing many container trucks with containers?
