Data is Plural: “The United States International Trade Commission maintains annual datasets of US import tariffs going back to 1997. The datasets include each impacted product’s eight-digit Harmonized Tariff Schedule code, a brief description, the duty rate, rate type, effective and ending dates, and more. The commission also publishes a tariff search tool and data on upcoming tariff rates. More globally, the World Trade Organization provides tools to query and download data about its members’ tariffs, as well as databases of regional trade agreements and preferential trade agreements.
