The International Copper Study Group (ICSG) is an intergovernmental organisation of copper producing and consuming states that functions as the international commodity board for copper. Its main purpose is to increase copper market transparency and promote international discussions and cooperation on issues related to copper. As of 2015, ICSG Share in the World Copper Market represents 76 percent of world copper mine production, 84 percent of world copper refined production and 81 percent of the world copper refined usage.
The creation of the ICSG was negotiated in 1989 in Geneva and was agreed to in a multilateral treaty known as the Agreement establishing the Terms of Reference of the International Copper Study Group. The ICSG came into existence on 23 January 1992, with headquarters in Lisbon, Portugal.
