International Copper Study Group
The International Copper Study Group (ICSG) is an intergovernmental organisation of states that functions as the international commodity board for copper. Its main purpose is to ensure transparency in the international copper trade.
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.
