The Chemours Company’s Hermosillo Cyanide Transloading Facility Achieves Fourth Certification Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that The Chemours Company’s (Chemours) cyanide transloading facility in Hermosillo, Mexico has been recertified in full compliance with the International Cyanide Management Code (Cyanide Code).  This is the Hermosillo operation’s fourth certification in full compliance under the Cyanide Code. The Cyanide Code is a voluntary industry program focused on the safe and environmentally responsible management of cyanide by companies producing gold and/or silver and by companies manufacturing, warehousing, and transporting cyanide.

The Hermosillo cyanide transloading facility was initially certified in full compliance with the Cyanide Code in September 2010 and recertified in February 2014 and in September 2017. As required under the Cyanide Code, the operation was again audited against ICMI’s Production Verification Protocol by independent professional third-party auditors. ICMI has received and accepted the auditors’ Detailed Audit Findings Report, which found the operation in full compliance with the Cyanide Code’s Production Principles and Standards of Practice. The Summary Audit Report and Auditor Credentials Form are available on the ICMI web site on Chemours’ Producer Signatory Company Page. The operation must be re-audited every three years to evaluate continuing compliance with the Cyanide Code.

The Cyanide Code was developed under the aegis of the United Nations Environment Programme by a multi-stakeholder Steering Committee, and is amongst the most established certification programs in the mining sector. The Cyanide Code is intended to complement an operation’s existing obligation to comply with the applicable laws and regulations of the political jurisdiction in which the operation is located.

ICMI has been established to administer the Cyanide Code, promote its adoption, evaluate its implementation, and manage the certification process for operations using, producing, and transporting cyanide. A detailed list of the operations covered by signatory companies’ applications, along with the full text of the Cyanide Code and its implementing and administrative documents, are available at We invite you to read our 2020 Annual Report, which can be viewed here.
