If you are shopping online outside the country, be aware of some custom fees charged on imported goods.
The 1.804/1980 Decret foresees the collect of a custom fee for imported goods above USD $ 100,00 or goods of equal amount on other currencies.
For shipments above USD $ 500,00 a customs declaration will be needed. You can learn more about that here (content in portuguese).
To know if an item has been retained due to tax payable, track your package and check if the shipment status is: "completed customs inspection".
Quick tip: You don't need to check on your package's tracking at every time. Turn on EBANX Track notifications and be informed whenever a customs fee needs to be paid in order to release your item.
