Evaluations are completed using the Avient Supplier Risk Matrix which identifies “high-”, “medium-” and “low-risk” suppliers based upon the following inputs: total business impact, supplier performance, and QMS profile (certification and self-assessment completion). If a supplier is designated as medium or high risk, improvement actions may involve – but will not be limited to – QF-05 completion, an on-site audit request, and/or QMS development. 3.3 Supplier On-Site Audit When deemed necessary, Avient will perform on-site supplier audits to verify suppliers’ compliance with this SQM. This plan shall include, but will not be limited to, provisions for prompt and effective notice to Avient, potential impact, provisions for restoration of disrupted manufacturing capabilities, and resumption of the manufacturing and shipment of products. 4.4 Sub-Tier Supplier Controls Suppliers are responsible for the quality of materials and products provided by their sub-tier suppliers and sub-contractors.
