I'm also interested in this.
I tried searching on the ANATEL site and didn't see any model in there.
I was wondering if it wasn't expressif's interest, if anyone (not the manufacturer) could start the homologation process.
Here are the requirements for doing so (in Portuguese):

Assembling the ESP8266 in a Brazilian Factory and then start the homologation process a possibility?
I think that would be way expensive.
Do you know of any other WiFi modules that are homologged in Brazil?
