Yeah, I think that problem was missed out, all you have to do is in your BasicComponents config disable the ability to craft the tin plate (Whereas it has no big usage) Example:
B:"Allow item.basiccomponents:plateTin Crafting"=false
The server owner would also have to do it for your config, maybe you'll see the empty cell recipe yourself, but on the server a tin plate would come out since the server hasn't configured it to make the empty cells. Just contact the owner and tell him to do so for his server.
On another note.
It sucks that MineChem was removed, I really enjoyed that mod.
