Some French consumers are looking for ways to do without American products to protest President Donald Trump’s policies on Ukraine. But close trading ties and the nature of multinational companies is making it tough to identify which products to boycott.

You just have to scan the barcode and it will check it against its database.
It is a pretty straightforward design that should be easy to implement/expand for specifically US products.
As a start many of the companies that are boycott targets for their complicity in Israeli crimes are also US-American or heavily involved with the US.
