Chaoda Valves has obtained CE certification from the European Union. CE certification is limited to basic safety requirements regarding the safety of humans, animals, and goods, not general quality requirements. Harmonized directives only stipulate essential requirements; general requirements are the task of standards. Therefore, the accurate meaning is: the CE mark is a safety conformity mark, not a quality conformity mark. It represents the “essential requirements” that form the core of European directives. The “CE” mark is a safety certification mark, considered a passport for manufacturers to access the European market. CE stands for European Conformity (CONFORMITE EUROPEENNE). In the EU market, the “CE” mark is a mandatory certification mark. Whether a product is manufactured within the EU or in other countries, it must bear the “CE” mark to circulate freely in the EU market, indicating that it complies with the basic requirements of the EU’s “New Approach to Technical Harmonization and Standardization” directives. This is a mandatory requirement under EU law. In response to new changes in the relevant clauses of EU CE certification, Chaoda submitted its product certification application and successfully obtained it. Since first obtaining EU CE certification in 2014, Chaoda valve products have passed certification, fully

Chaoda Valve Group Co., Ltd. has received certification from TÜV SÜD Management Services Ltd., confirming that it has established and implemented a quality management system within the scope of “valve design and sales,” and has passed the audit. ISO is the abbreviation for the International Organization for Standardization. In 1987, the International Organization for Standardization published the ISO 9000 international standard for quality management systems, suitable for use by various industries worldwide to improve the quality of their products, projects, or services. The ISO 9001 quality system specifies the requirements for a quality management system, including developing quality assurance models for design, production, installation, and service, used by organizations to demonstrate their ability to provide products that meet customer requirements and applicable regulatory requirements. For external stakeholders, when customers learn that the supplier manages according to international standards, has obtained ISO 9000 quality system certification, and is subject to rigorous audits and regular monitoring by certification bodies, they can be confident that the company can consistently provide qualified products or services, thus confidently entering into supply contracts and expanding the company’s market share. It can be said that the benefits are immediate and significant in both aspects. Chaoda Valve has

Zhejiang Chaoda Valve Co., Ltd. (later upgraded to Chaoda Valve Group Co., Ltd.) obtained API 600 certification from the United States on November 17, 2003, certificate number 600-0011. The product range includes bolt-connected steel gate valves with bonnets. API is the abbreviation for the American Petroleum Institute. Founded in 1919, one of API’s important tasks is to standardize equipment used in the oil and gas industry, ensuring the safety, reliability, and interchangeability of equipment used in this industry. API certification, which was once a potential need, became an explicit requirement during China’s accession to the WTO. Orders for oil machinery products increasingly emphasize API product quality recognition, due to API’s special status in the oil industry. Currently, both global oil purchasers and manufacturers widely adopt API standards. Purchasers consider whether products meet API standards and whether manufacturers have obtained API certification as prerequisites and important qualification conditions for bidding. API certification can be divided into three main categories: API individual certification, API quality management system and environmental management system certification, and API product certification. Companies need to determine which type of API certification they should apply for based on the categories of products they manufacture. API certification provides companies with
