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. 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. In these cases, Avient commits to minimize the number of animals as much as possible. • Refine – Avient does not have animal testing facilities, any necessary studies are conducted by external testing facilities that are certified by Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) and that are committed to utilise methods that minimize pain, discomfort and distress before, during and after the test period.
