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”
Rio is nowhere as bad as half the rest of the territory in matters of extreme heat. Mato Grosso, Amazonia and Pará are frequently way worse, and also where the majority of illegal forest fires for land clearing happen.
