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”
On the other hand, in the USA I bought a MikroTik CRS312 12-port 10Gbps network switch from a Latvian online store (Getic) for ~$500 plus $20 shipping, and didn’t have to pay any import duties/taxes because it’s under the $800/day duty-free limit. Way cheaper than buying it in the USA, where the same item is commonly $600 + taxes.
Australia is similar and has a $1000 duty-free limit, however online stores that have a lot of Australian customers do need to charge Australia sales tax (GST) of 10%. It can still end up cheaper, so there’s still a lot of grey imports in Australia (which is where you buy products that are available in Australia from an online store in a different country because it’s cheaper).
