I suppose a plan of this magnitude has been going on for years already, and has not been impacted by the recent tariff drama.
But I wonder if the steel tariffs uncertainty would play a role in the future for implantation in the US. Risk averse companies may think twice before locating a plant in a geographical zone where raw material prices and supply chain parts may change prices wildly and unpredictably. This kind of political unstability is not good for the business environment in the US.
Also, NAFTA is still the law of the land, since congress has not ratified its replacement (
