Not sure about immigration procedures at GRU, Brazil, but for many countries at your first port of entry (GRU) you go through immigration & customs with all your carry on and checked baggage and then check in/bag drop for your onward domestic flight.

Thank you - that makes more sense! And I'm not overly surprised that BA gave me an answer to a question that I didn't ask.
I'll pick up my bag and do immigration etc in GRU as you suggest. Thank you so much for setting me straight!
