All of the product data shown on the site is classified using either SITC (Standard International Trade Classification) or HS (Harmonized System).

For historical SITC classification data (1962 - 2000), we use data from The Center for International Data from Robert Feenstra1. For more recent data (2001 - 2017), we use data provided by UN COMTRADE.

For all of the HS data used throughout the site (1995 - 2017) we use the BACI International Trade Database2. The original data comes from the United Nations Statistical Division (COMTRADE), but is cleaned by the BACI team using their own methodology of harmonization.
