Alcoa
Estimated Cost: $32 million in the first quarter of 2019
Alcoa is the leading manufacturer of aluminum in the U.S, so it was hit hard by the 10% tariff on all U.S. aluminum imports imposed by Trump in March 2018. Not surprisingly, Alcoa’s stock price plunged 50% over the next 15 or so months, Market Realist reported.
Alcoa, which ships aluminum from Canada to the U.S., paid around $32 million in tariffs in the first quarter of 2019. There has been some good news for Alcoa, however: In May 2019 Trump exempted Mexico and Canada from the aluminum tariffs.
