Since yesterday I have CMM's etc in my surface outpost port.
1) Build on a HMCW a surface outpost port Civilian (Nona for example)
2) Build a refinery hub on the same planet as your outpost port = only two items in the market of the port
3) Build a space farm and a military hub = otherwise you might get into lockdown etc
4) Build a secundary hub on the same planet as your outpost port
After that check your market of your outpost port, normally you would have more than 2 materials in the market and you might see CMM etc
Success
