The White House has been planning for this eventuality and has many other legal routes to rebuild the tariff wall. On Friday, at a hastily arranged press conference following the decision, an angry Trump said he would invoke Section 122 of the US Trade Act to impose global tariffs of 10 per cent on top of those already in place. The provision allows the president to implement import duties of up to 15 per cent, without congressional approval, for up to 150 days. The president also said his administration would initiate actions under Section 301, which allows him to impose unlimited tariff rates in response to discrimination against US businesses, pending an investigation. There are other legal levers he could pull beyond these options too.
