On November 14, 2019, SGS's supervision and audit of our company's ISO9001 quality management system 2015 version ended successfully. It is determined that our company's culture media products' quality management system meets the requirements of the ISO9001:2015 standard, and the corresponding certificate was issued to our company on November 27, 2019. This means that although our company has only been established for just two years, the authoritative certification body has recognized our quality management system; it also represents an affirmation of the "Quality First" principle that QuaCell products have always adhered to.
