I have a question regarding at what stage VAT is levied, and how is it taken into consideration if one is importing from America. Before someone goes and tells me "Do your research" I have tried in vain(EI VAIN

An Example(Figures arent accurate in anyway)
Importing say Remote control cars from America;
#500 Euro worth of goods
#100Euro Shipping
#50 Euro Import Tarrif
=650 Euro cost to my door
Is 22% (I know its soon 23, lets just go with 22 for now) VAT added to this 650 Euro figure? (143 VAT)
Say one estimates to add 100 Euro on top of that to sell the goods for a worth of 750 Euro, is it 22% of this figure?(165 VAT)
Or is it 22% of the value added (I read this on some indian website) of 100 Euro? (22 VAT)
Thx for your time.

PS. I guess one cant claim VAT back from importing from a country outside of the EU?
