Node import with taxonomy hierarchical last item

I would like to import serveral nodes. There is a taxonomy field on node type and my terms are in hierarchical structure, for example Washing/Soap, Bathing/Soap

My csv looks like this:

If i wanna keep the taxonomy hierarchical how can i import these terms to be distinguished from each other(cos there are two soaps with different term id). I cant use the Soap word with both, this is why there should be sg(in this case parents(Washing and Bathing)) which could identify the Soap word.

So how can such nodes be imported like these? THX
