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”
Tell them to write it off as engineering samples 🤷. That’s the only thing that comes to mind…
Maybe if you write what tax deductions you have on import, I might have better ideas 😉.
