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”
Is that some sort of import tax or an absolutely insane sales tax?
Federal import tax, plus state tax based on the total value with the federal tax
Both taxes are also applied on product price+shipping. So it would be a state 17~18% tax on top of a 60% federal tax on product+shipping+ 15 BRL delivery fee.
