The International Nickel Study Group (INSG) is an intergovernmental organization established in June 1990, in The Hague, Netherlands, within the framework of the United Nations.

[4] Specifically, this is done by monitoring the nickel economy, exchanging information with members, developing studies on specific issues, to "improv[e] the information available on the international nickel economy".

[3] Currently, the most visible work of the INSG are statistics (World Nickel Statistics)[5][6] and forecasts[7] for the nickel market, being commonly cited or referred in industry news,[8][7] studies on commodities[9] and company reports and presentations.

[10] Members of the INSG are Governments of nickel producing and consuming countries.

Membership is open to countries with interest in nickel production, consumption or trade as well as "intergovernmental organizations with responsibilities in respect of the negotiation, conclusion and application of international agreements, particularly commodity agreements".
