Guoheng Youhe Advanced Materials’ Laboratory has once again successfully passed the CNAS supervision review, and its technical strength has been recognized by international authorities.

Recently, the testing laboratory of Guangdong Guoheng Youhe Advanced Materials Co., Ltd. (referred to as "Guoheng Advanced Materials") successfully passed the supervisory review of the China National Accreditation Service for Conformity Assessment (CNAS) again in April 2026. This achievement indicates that the company has continuously maintained an advanced international level in terms of testing technology capabilities, quality management systems, and data credibility, providing more authoritative quality assurance for global customers.

CNAS is the only national-level laboratory accreditation body in China. Its accreditation qualifications serve as the core pass for international mutual recognition of testing data. It is rigorously evaluated in accordance with the internationally applicable ISO/IEC 17025 standard, covering all dimensions of technical capabilities, equipment management, personnel qualifications, and quality systems. Laboratories that pass the evaluation can issue reports with the CNAS and ILAC logos, and these reports can be mutually recognized in 106 economies around the world.

Since its accreditation by CNAS in 2015, Guoheng Advanced Materials Testing Laboratory has always strictly controlled the entire testing process in accordance with the highest international standards. During this supervision review, the review experts conducted a comprehensive audit through on-site operations, equipment verification, personnel assessment, and record tracing. They unanimously determined that the laboratory's technical capabilities are stable and reliable, its management system is continuously effective, and its testing data is accurate and traceable, fully meeting the requirements of the CNAS accreditation criteria. As a result, the laboratory successfully maintained its accreditation status.

The testing laboratory serves as the core hub for the company's quality control and an important support for technological innovation. This time, it has continuously obtained CNAS accreditation, providing international-level technical support for the research and development of environmental-friendly new materials, product quality testing, and supplier qualification review. This ensures that each batch of products meets the strict environmental and quality standards both domestically and internationally, helping the company maintain its leading position in the circular economy and green manufacturing sector.

Currently, international trade has increasingly strict requirements for the authority and mutual recognition of product inspection reports. The CNAS accreditation qualification has become an important threshold for enterprises to participate in international competition. Guoheng Advanced Materials’ successful passing of the CNAS supervision review is not only an authoritative endorsement of the company's technical strength and quality management, but also effectively eliminates technical barriers in international trade, enhances the credibility and competitiveness of products in the global market, and lays a solid foundation for further expanding overseas markets and deepening international cooperation.

In the future, Guoheng Advanced Materials will take this successful CNAS assessment as an opportunity to continuously uphold the concepts of "quality first, innovation as the core, and green development". It will continuously upgrade its testing technology, improve its management system, and strengthen its R&D capabilities. With international-leading quality standards and technical levels, it will provide customers with higher-quality products and services, and contribute more to the high-quality development and green low-carbon transformation of the advanced materials industry.
