If you're looking for the player base commodities you won't find them listed, not even in FLStat.
However, if you check the Bases list in FLStat it will tell you if commodity is sold there or not, for E.G Plasfoam Conduits are not in the commodity list, but if you check Rugen Station (Omega 3), it lists them as a commodity that's sold on the base.
What I done was, looked at where you bought the old player base commodities, checked what stations sell them, then check that list of stations for the new commodity. I found them all this way.
If you're looking for Ores/Minable commodities, you need to use FL Companion 2.01, load it as admin, and then "Load Dynamic Economy...", then they it will show sell points for Ores.
