This happens here too. With mid range appliances, if a brazillian company produces the same kind of products, every imported competition is overtaxed, so the final prices goes up.
This happens in order to make the internal market better for national companies.
Other reasons might be that they simply don't have a distribution center on your country and are paying full taxes in order to sell to you haha.
The only fuckers that goes beyond this is Americans, they get EVERYTHING cheaper than the rest :(
