OK, these folk with an Arkansas postal address claim to ship to Brazil and most everywhere else:

I take it you don't want to wait 10 years for blueberry seeds to produce a plant that you can harvest fruit from?

:-)

You might want to tell them to not draw too much attention to the packaging but I've found when I lived in Switzerland if you ship via UPS or FedEx customs tends not to be a problem.

Good luck.

Hi, I have contacted Berries Unilimited that you recommended above, but they said they don't ship abroad... too bad... Thanks anyway.

You may have better luck with companies that can ship blueberries in-vitro as tissue culture plantlets. Such companies can usually supply the phytosanitary certificate needed to comply with your import permit, since the plantlets are sterile.

The drawback is that you have to order a whole flat, and also have the greenhouse and misting facilities to root the plantlets and acclimate them.

Nourse Farms ships to Canada, but I don't know about Brazil? Worth asking.
