Yes, it looks like my research now has a global following.
Snuff manufactured in Brazil or more usually snuff manufactured in Europe using Brazilian tobacco crops up quite frequently in older references. There is even an account of Brazilian tobacco plantations in Daniel Defoe’s Robinson Crusoe.
At least one German snuff uses Brazilian tobacco (possibly more than one) but the country itself seems bereft of snuff. The contemporary scene shows plenty of sites for shamanic snuff made by indigenous people from the Amazon basin but nothing that I can see for tobacco nasal snuff - save this one site.
This particular snuff is reviewed here but I don’t understand Portuguese. Nevertheless, the tin is ridiculously tiny and the snuff looks a little coarser and lighter coloured than is usual for SPs. That it has an aroma of bergamot is all I can understand from the reviewer.
