Getting FCC type aproval is a system between the manufactuer and the FCC.
None of the Baofeng, Quansheng radios have gone through the FCC hoops to get approved.
It is an expensive process and would increase the cost of a radio.
For amateur bands, there is no type acceptance, so an export type would have to meet with Brazilian laws.
It can take some time for customs to release such imports, so have patience.
