In the Avient Supplier Code of Conduct, which is applicable to the suppliers of ColorMatrix, Avient prescribes that its suppliers should not use slavery or human trafficking in connection with any product supplied to Avient. The procedure outlines how supplier risk is made visible and actionable through the use of the “Vendor Risk Matrix” as well as understanding the status of the suppliers’ current management system.
