From the Document: "The trade practices of U.S. trading partners and the U.S. trade deficit are a focus of the Trump Administration. [...] While tariffs may benefit a limited number of import-competing firms, they also increase costs for downstream users of imported products and consumers and may have broader negative effects on the U.S. economy, as well as several policy implications. The multiple tariff increases applied to date, ranging from 10% to 45%, affect approximately 15% of U.S. annual imports. This amounts to $393.3 billion of imports using 2018 annual data; notably, the tariffs went into effect at various times in 2018 and 2019."
