They are called "import duties" in English, and every country sets its own rates. The Portuguese term appears to be "Imposto sobre a Importação"; perhaps you can find an official Brazilian government website.
There is usually a "duty free allowance". If the value of your purchases is more than this amount, then you will need to declare your purchases at customs when you enter Brazil. If it's like most other countries, the customs officials will determine the value of the goods (it will help if you can show the purchase receipt) and tell you how much you owe. You should be prepared to pay on the spot, or else the goods may be held at the airport until you come back and pay later.

Note: if you open the boxes and somehow you show some use, the market value will be decreased (think not about you, but the value one random person will think such open cases will have), so you may get lower than allowance (or in any case you may pay less). Jan 22, 2019 at 9:16
1This answer is correct. You can bring up to US$500 free from taxes, if arriving by air (300 by sea or roads]. Above that value the tax is 50%. I’ll find an official government site stating that and post as an answer.– gmauchJan 24, 2019 at 0:58
