President Donald Trump announced Monday that he will be imposing “substantial” tariffs on any country that does not purchase American-made furniture, presumably in addition to his sweeping so-called “reciprocal tariffs” already placed on hundreds of nations.

Whether Trump’s pledge would boost domestic furniture manufacturing remains to be seen, though the pledge comes just shortly after the president
