What does the post bind?

Trump wrote on Truth Social on Monday that Bombardier must build in the United States if it wants the American market, and said its products were not good enough. The post states a demand plainly; it does not say by what route a sale would be stopped. It is unclear how the president intends to do it.[1]

The product itself makes that demand awkward. Bombardier's jets are built at facilities in Canada, the United States and Mexico and comply with the North American free trade agreement, known as CUSMA in Canada and the USMCA in the US, which Trump signed in his first term. The company runs a factory in Kansas building special mission aircraft with 3,500 American workers, and US-based customers operate 5,100 of its aircraft. The targeted good meets the rules and is already built in part inside the United States.[1]

The instrument that takes effect on Tuesday

One instrument in this file really does bind, and it is not in Washington's hands. Canada's retaliatory tariffs on 20 billion dollars of American goods take effect hours after the post. They follow the collapse of trade talks last month and the 50 per cent tariffs the United States placed on a range of Canadian goods.[1]

Turning a demand into a ban requires an authority that can reach a good which meets the rules and is partly built in the United States. Because the post names no such authority, the weight of the threat depends on which instrument is chosen and on the findings that instrument requires. It may equally be an opening move: if the aim is to bring Ottawa back to the table, the point can be won without any instrument at all.[1]

Who takes the decision?

The parties who would have to comply do not sound willing. Quebec premier Christine Fréchette called the company a source of pride for her province and said Quebec would not let anyone dictate where its firms must produce. The decision to move production sits neither in Ottawa nor in Washington but with the company and the province that hosts it.[1]

The question is not new. In July I took up Washington's new tariff authority under Section 301 and argued that the tariff threatened against the EU became binding only through an investigation producing country-specific findings and a process. The Bombardier post repeats the same gap in another sector: the demand is explicit, the authority unnamed.[2], [1]

The observable signal is simple. A halt to Bombardier sales in the US would come from a published decision naming the company, not from the Truth Social post. Until such a decision appears, Bombardier's standing in the American market rests on the CUSMA rules its Canadian, US and Mexican facilities already meet.[1]
