Cummins
Estimated Cost: $250 million in 2019
You can be forgiven if you’ve never heard of Cummins, but it’s an important engine in the economy — at least in the sense that the company makes engines for a wide variety of machines. Cummins estimates that tariffs will cost it some $250 million in 2019, and only $100 million of that can be attributed to the tariffs on steel and aluminum. The other $150 million is from direct tariffs on its own engines, many of which are manufactured in China and then imported.
