Siblings Marie-Charlotte Piro and Romain Piro stand among some of the olive trees they harvest in Tuscany, Italy, to create their olive oil. But now, it’s looking elsewhere for growth, thanks to President Trump’s new tariffs on almost everything the United States imports, including olive oil. When he began making olive oil, he sold it by loading up the back of his Volkswagen van, “driving to Paris, knocking on the back door of Michelin-starred restaurants and selling the olive oil in the alley,” his sister recalls. Now President Trump’s new tariffs are adding costs and complications for Italian olive oil producers, including Olio Piro, and their customers. Larger olive oil producers tend to store their olive oil after the fall harvest and then ship throughout the year, meaning that many have had to navigate the changing U.S. tariff rates on a daily or weekly basis.
