Guang’an Chengxin Chemical Company and Inner Mongolia Chengxin Yongan Chemical Company Certified Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Guang’an Chengxin Chemical Company and Inner Mongolia Chengxin Yongan Chemical Company, both located in the People’s Republic of China, have been certified in full compliance under the International Cyanide Management Code (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.

For each operation, ICMI has received and accepted a Detailed Audit Findings Report prepared by an independent professional third-party auditor who evaluated each operation against ICMI’s Cyanide Production Verification Protocol and found each operation in full compliance with the Cyanide Code’s Production Principles and Standards of Practice. The Summary Audit Reports and Auditor Credentials Forms are available on Guang’an Chengxin Chemical Company’s Signatory Company Page and on Inner Mongolia Chengxin Yongan Chemical Company’s Signatory Company Page on the Cyanide Code website. The operations 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. The Cyanide Code is intended to complement an operation’s existing obligation to comply with the applicable laws and regulations of the political jurisdictions 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. 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
