Steel - why Tier 4?
Mats (iron and coal) are both A3. And steel is lvl 60 to make, steel picks 66, etc. (On par with coal at 60). Steel should be in Tier 3 crafting, or some adjustment made to keep things sensible and in line (e.g. coal moving up a tier).
Aluminum being Tier 4 should mean smelting and using it should be Tier 4. Etc.

I don't see an inherent problem with the requirements being different, but I do agree that they should be in the same region, since otherwise there's a lot of travel involved - and when it's 15 minutes each way, that's quite problematic. In this particular case, it's even worse since there is not a region 4 in the game yet, so the raw materials pile up indefinitely and take up inventory space while waiting for the update.
