Games : In X Rebirth 3.0 where can I trade (ore, nividium, crystals, etc.) during the campaign when PMC is super-pissed at me?

Can someone please explain this to me:

I am in the campaign where I have to sell 300 units of food rations (which I did with my Container type ship), and I have 2 Fedhelms and 1 construction vessel.

My Fedhelms are really freaking rich with supplies, but because of my reputation with PMC, I can't seem to trade the goods (ore, nividium, crystals, etc.) ANYWHERE.

Does someone know where I can sell these goods? I've checked all of the metalworks yards (including the friendly ones) and every time I bring up the trade menu (SHFT+T) and I try to select ORE, it says that my reputation with PMC is too low (Even if I'm in DeVries).
