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"
The former is only possible through institutional compulsion and coercion.
You cannot enforce any contracts without some sort of coercitive force. If the person renting a home stops paying, the landlord will use force to evict the person. The only difference compared to the govt is size. You didn't pay taxes? Here, lemme force you to stay in prison for a while, also here's a fine on top of that.
The latter is through a voluntary contract that expresses the cooperation of both parties to work for each other, as they have a property interest in specific performance of the other
Not all contracts are voluntary and, more importantly, the workers are almost always the weaker party when it comes to negotiation. There's a reason unions (whether they actually do their job is a different matter, let's avoid that for now) and work regulations exist in civilized places, because otherwise, people will end up as slaves or almost slaves. If you leave it to the market to "self-regulate", you'll just get feudalism 2.0, where companies become the new noble houses, lording over their wageslaves (serfs and peasants), who should be grateful they're allowed to work. Not to mention the constant bullshit of "if you work hard enough, you too can become a noble!"
Really, any sufficiently big company will act just like a govt, full of unnecessary bureaucracy
