G200 EU is a potash feldspar imported from Spain that is being sold by Imerys as an equivalent to the now unavailable G200 Feldspar because the of the mine closure in 2013 due to the deposit being depleted. Also due to the Custer Feldspar mine closure we are recommending either the G200 EU Feldspar, G200#2R Feldspar or the Mahavir Feldspar as suitable potash replacements.
