Trade in Raw Materials visualization represents a subset of the OECD Inventory of export restrictions on industrial raw materials. A detailed methodological note for the Inventory is also available.
Production (2013) and reserves data (2014) are collected and disseminated by the United States Geological Survey (USGS), with the exception of coke and coking coal production data which are disseminated by the U.S. Energy Information Administration and the International Energy Agency (Coal Information 2015) respectively. Access to the data and methodological notes can be found in the Mineral Commodity Summaries and Individual Commodity Data Sheets, Coal Information 2015, EIA, U.S. Energy Information Administration. Export data (2013) are available through the United Nations Comtrade Database.
Reserves refer to known reserves. See definition in USGS Mineral Commodity Summaries 2016, Appendix C—Reserves and Resources. Production is mine production. Year is generally latest available at USGS, usually 2013. Trade data is gross exports (i.e., re-exports are included) aggregated over raw materials and semi-processed products. Exports data generally refer to 2013.
