I also need to find a close raw material trader but cant because there is no HIP 36601 in Inara?
Being quite far out of the Bubble, most raw materials are more or less the same distance away - back in the Bubble.
Note that there is no shard site with selenium. If you want to completely fill up on all raw materials in this fashion, you will essentially need four full trips. Filling up all lower grade materials by down-trading is possible from a full bin of grade 4 as it requires 106 units of the G4 to do this. Thus, the four trips required if you want to fill all raw materials in this fashion will be:
1. Fill all the grade 4 materials and trade down for the grade 1-3 materials in the same categories. Everything that is left you can cross trade for the grade 1-3 materials in category 4 (iron, zinc, tin).
2. Fill everything up and cross trade to category 4 grades 1-3. Spend any remainder on cross trading for selenium.
3. If necessary, fill everything up and cross trade for selenium.
4. Fill all remaining grade 4 bins.
You may get away with only 3 trips depending on how full your material bins are at the moment as you may fill up your category 4 materials (including selenium) in step 2 and then you can skip step 3. Do not forget to down trade all of your grade 4 materials before going to the shard sites in step 1 as this will allow you to harvest more materials once you get there.
