Raw materials are sourced from qualified suppliers with supplier qualification and monitoring systems in place. We also perform risk assessments for critical raw materials used in GMP processes every three years. This includes visual inspection of raw materials with documentation tracking of the Certificate of Analysis (CoA), Certificate of Origin (CoO), TSE/BSE statements, and animal-free statements, if applicable. Identity confirmation is performed for some critical raw materials before accepting. For animal-derived materials, we always source from countries considered to be a negligible or controlled BSE risk.
