If the origins are so fuzzy, I guess other manufacturers would very soon adjust their part lists/part origins to avoid the tariff?
Fuzzy is a feature, not a flaw. It allows the president to unilaterally pick winner and losers. Other manufacturers can do all sorts of things to try to be compliant, but ultimately the only way to be in compliance is to bend the knee. They’re welcome to sue, but that could take years and millions to figure out.
Are you arguing that the fuzziness was built into the system previously to allow presidents to pick winners and losers in the auto industry? Do you know if there are clear examples of past presidents actually using that power?
