Yes, you’re looking at ~92% tax right there. Final price jumped from ~113 dollars (584BRL) to ~220 dollars.
EDIT: A bit of clarification, when buying from abroad there’s a flat 60% federal tax if the thing + shipping price surpasses 50 dollars. Then there’s a state tax that can vary between 17-25%, which goes on top of the total taxed value. Part of the tax is literally “tax of a tax”
I think the real irony is that, up to 1993, it’s safe to say 99% of all computers we had here were contraband, because the taxes back then were even more absurd. Never mind the hyperinflation of the time.
