If Trump really raises the drawbridge of tariffs, Mexico will be the one to pay the heaviest bill. In the globalized world, the United States is a big consumer that imports almost everything. And much of it is imported from neighboring Mexico, whose vulnerability reaches even to Italy: in fact, Mexico has 1,800 Italian companies, according to a census by CaMexItal, the Italian-Mexican Chamber of Commerce. Of those, a large chunk also have factories: about 300. What will happen to Mexico will have present repercussions in Italy: many of those 300 factories were built on Mexican soil to take advantage of lower costs and then export to the wealthy United States, given the geographic proximity as well. It is a Made in Italy in Mexico that serves to keep products competitive (and make more margins). Any new taxes on imported goods to encourage the return of foreign production at home (reshoring), however, are likely to be a shingle for Italian companies. Scrolling down the list of Italy in Mexico, there are all the country's big industrial giants: from ENI to Leonardo, from Ferrero of sweets to Pirelli; from Brembo to Campari. The biggest slice of the pie is made up of Italian companies that have relocated: first and foremost Ferrero of Alba. In 2012, the global confectionery giant opened a factory in San Jose. Forty-five thousand tons of Nutella and Kinder chocolate come out of that factory every year: 40% take the North American route.
