Well, I tried to find info which I thought I saw somewhere but I can´t so, I might be wrong. Just to not spread false rumours... Clarification from some admin or dev should clarify it better.
I think you can buy it with any ID.
I just bought them at NEWPORT Station (S-13) they Need 5 cargo per unit.
Hope this helps you - I don't know any other place where to buy them.
