I believe it does NOT apply. I'll try to get more information from my sister who is a lawyer and has recently moved back from Paris to Rio (sigh...) You should also try to call your local embassy/consulate to confirm.
An additional problem will always be dealing with the mood of misinformed (if not corrupt) agents at your port of entry.
I can give you an example: after I moved to the US, I was visiting Rio and needed my laptop for work. So I called the federal police supervisor at GIG
before my flight and asked if there was any provision for me not to pay any duty on it, since I'd be leaving the country a week later with the laptop. He told me that wasn't a problem, and I only needed to sign a document when I arrived and present my laptop when leaving and I'd be exempt. Sure enough, I arrive at GIG
and the agents working there tell me there is no such provision, there never was, and I have to pay the import tax on the computer plus a fine. I try to argue (politely, as I'm not stupid and don't want to be arrested) and point out their lack of logic and rationality but it is to no avail. Fortunately, I remembered the name of their supervisor with whom I had talked on the phone a week before, and they finally let me go (naturally without admitting they were wrong).
Ridiculous. Either follow the law or don't. While I was there arguing, I saw the agents do the same thing with a professor who was returning after teaching for a couple of years at the University of Tokyo. One can imagine he was bringing a lot more in terms of electronics, and the agents were giving him a very hard time. I felt very ashamed of the country.
Anyway, my advice would be to get something in writing from your consulate/embassy to cover your arse and avoid a similar situation.
