Hebei Shuangxing Photographic Chemical Co., Ltd., abbreviated as "Hebei Shuangxing," is located in Wuyi County, Hengshui City, Hebei Province. Established in 1981, it is one of the earliest manufacturers of EDTA in China. Hebei Shuangxing is dedicated to integrated research and development, production, and sales, offering EDTA and DTPA series chelating agents, EDTA series metal salts, DTPA series metal salts, as well as photographic chemicals such as EDTA ferric ammonium salt, ammonium thiosulfate, potassium sulfite, and customized non-standard related chemical products, serving modern life. Adhering to the "Shuangxing" philosophy of "mutual benefit and shared prosperity with customers," Hebei Shuangxing continuously develops products that meet customer needs and improves process quality levels. It has established a collaborative mechanism with chemical research institutions and universities, combined with customer requirements, to provide customized services for related products, offering multiple choices to customers while reducing supply risks and procurement costs. The corporate values of Shuangxing Photochemical revolve around striving for four areas of satisfaction: customer satisfaction, employee satisfaction, social satisfaction, and shareholder satisfaction, maintaining the order and balance among these four aspects. Customer satisfaction means delivering the right quality and quantity of products at the right price to the specified location at the right time. Employee satisfaction involves establishing a people-oriented philosophy, valuing human resources, providing a safe and comfortable working environment, and offering a platform where effort and reward align, allowing employees to realize their personal value—satisfied employees produce products that satisfy customers. Social satisfaction entails creating a conscientious enterprise from the perspectives of safety, environment, taxation, and employment, contributing to social value and progress. Shareholder satisfaction means building a long-term and stable return platform for shareholder investments, ensuring the company operates sustainably under the guidance of correct values and provides reasonable returns to shareholders.
