Tariff factoids: https://www.wsj.com/articles/most-economists-see-tariff-effects-on-u-s-economy-as-limited-1536847200 Under President Trump, the U.S. has imposed tariffs on about $113 billion of imports, goods that represented about 4% of all U.S. imports in 2017. Major U.S. trading partners have responded with tariffs on about $70 billion of exports, or about 3% of U.S. exports. The sum of goods that have had tariffs actually imposed is less than 1% of U.S. gross domestic product. These numbers could increase, of course.
