U.S. reporting companies that manufacture products (or have others manufacture products) that contain 3TG metals or their derivatives (tantalum, tin, tungsten and gold) that are necessary to product functionality or production are required to assess their supply chains and report to the SEC on whether those materials are sourced from the Democratic Republic of Congo and adjoining countries. We expect our global supply chain partners to do the same, whether or not they are subject to the reporting requirements of the Act. Avient is equally committed to complying with the reporting obligations under Section 1502 of the Act and the related rule issued by the SEC.
