To be quite honest I dont think anyone can answer that. Most likely, you wont have to pay anything depending on how you prepare the invoice. But, you can go to the aduana website and look up the duties. Also probably have to pay the 18% ITBIS
I purchased an 800 dollar cellphone from google and paid nothing (2 x). I had to wait a week or two as they only ship cellphones on a certain day, but it was worth it.
Good Luck
