The datasets build upon existing national data sources for imports and tariffs: Eurostat’s COMEXT and European Commission’s TARIC data sources for the EU and Census and US International Trade Commission (USITC) data sources for the US.
The EU database is a panel covering all exports of any non-EU country to the group of EU15 countries of any 8-digit product in each year during the period 1997-2016. For this highly disaggregated trade flow, the EU database provides information on: the value and quantity; the applied most favored nation (MFN) tariff the country-product faces in the EU; the unilateral preferences that the country-product can benefit from in the EU in that year (African, Caribbean and Pacific Group of States or Generalized System of Preferences (GSP), Everything But Arms Initiative (EBA)); and the best preferential tariffs that the country-product can benefit from in the EU in that year.
The US database is a panel covering all exports of any country to the US of any 8-digit product in each year during period 1997-2017. For this highly disaggregated trade flow, the US database provides information on: the value and quantity; the applied most favored nation (MFN) tariff the country-product-year faces in the US; the unilateral preferences the country-product can benefit from in the US in that year (e.g., GSP, Africa Growth and Opportunity Act (AGOA)); and the best preferential tariffs that the country-product can benefit from in the US in that year.
