Animal Testing Policy AVIENT CORPORATION AND SUBSIDIARIES In the normal course of doing business, Avient is required to conduct testing to ensure the safety of its products. We are committed to producing safe products complying with all applicable laws, regulations and industry standards while avoiding unnecessary animal testing. Avient is committed to replacing, reducing and refining the use of animal testing by applying the following practices: • Replace – Before any vertebrae testing, Avient will investigate the use of alternative methods and approaches, including use of data that is already publically available, computational toxicology models and read-across to available data for similar substances. • Reduce – Avient will only consider animal testing if it is a legal requirement, or to ensure the safety of our products, when no suitable alternatives are available.
