Many large American companies will have trouble with the tariffs. Just because they advertise as Made in the USA, a lot of parts are made abroad and imported to build the final product. Brands like Fender make nice guitars in Mexico.
Also set to raise American production costs, Ontario, Canada's most populous province, is adding a 25% surcharge to all electricity exports sent to the U.S. 85% of potash, an essential ingredient used by the farming industry in the U.S. comes from Canada. Wait until those good ol' boys realize this.
