How do you get to know about the exporting taxes?
The company I was working for sells TV set top boxes. We have an operation in Brazil doing the assembly of kits. My division was selling a different sort of thing and we were looking into how we could keep the sell price as close to the price to the rest of the world as possible. So the sales guy who was in the country did some investigation and reported back. It wasn't just the straight import tax, it was at every stage some other form of tax got added on and eventually the end user ended up paying close to three times the real price.
As this was a very complex product it wasn't suitable to have the boards assembled and tested in country. The tax relief on the manufacture was tapered according to how technical the manufacturing steps were, so assembling the boards into a final product didn't get rid of it all. There was also a large amount of test equipment we would have to put in the factory and that attracted import tax as well.
In the end it was all put on hold because of licensing decisions being delayed due to up coming elections, with different candidates promising to do different things.
