Ensure suppliers adhere to internationally recognized standards such as ASTM D-1238 (for melt flow index), ISO 9001 (quality management), and environmental certifications like ISO 14001. For food-grade or pharmaceutical applications, certifications such as FDA compliance or EU Food Contact approval are critical. Request detailed test reports, Certificates of Analysis (CoA), and compliance certificates for each batch or lot. Implementing third-party testing or audits can verify supplier claims, reducing risks of non-conformance, contamination, or regulatory issues in your target markets.
