Even if it is exclusively sourced/manufactured all within one state it will almost certainly be considered to be within federal jurisdiction.
Wickard v Filburn indicates that even if the item/material is exclusively sourced from inside only one state it still can
affect interstate commerce by changing overall supply.
In that case, Filburn was growing wheat to use as animal feed. He was growing it all in one state, it wasn't ever even being sold. He was using it all himself.
SCOTUS found that because the grain he grew affected overall supply, it still affected interstate supply and therefore it could still be regulated federally.
