Normally, in any country of the world, you do not pay taxes on things, you import just temporary.
I doesn't matter if it is an Ferrari just for pleasure or if it is a new machine you bring in for a trade show for your business. The thing is, that you need to make a customs declaration (and not the easy one that you normally do at the airport as a traveller). You do the full declaration including information for which reason you are importing, when you will export it again, including all the tax codes. Then when you leave you need to declare the export.
