“All outsourced, vendor, and subcontractor companies down the entire production/waste chain to the raw material must meet US environmental regulations.”
If they don’t want to do that they can save a lot of effort by onshoring rather than outsourcing to lowest bidder shady overseas companies.
But I think that overall the process is not anywhere near as hard as you say it is. Corporations use purposeful, tactical ignorance to avoid regulations.
Done, fixed the loophole.
