Shandong Laiyu Chemical Co., Ltd., established in 1984 and headquartered in Shandong Province, is a professional magnesium salt manufacturer integrating R&D, production, and sales of magnesium salt products, organic new materials, fertilizers, soil conditioning solutions, environmental protection products and engineering, as well as health-focused projects. The company boasts its own R&D team and a full set of advanced testing equipment.

　　Laiyu places environmental protection at the forefront of its corporate development. The “three wastes” (waste gas, wastewater, and solid waste) from industrial production have been properly managed: solid waste is converted into fertilizers, and water is recycled. The company has passed the environmental review of Laizhou City and has been officially accepted and filed by the Yantai Municipal Environmental Protection Bureau. Beyond its own environmental governance, Laiyu actively undertakes social responsibility in this field. In response to severe smog conditions in China, the company successfully developed and produced dust suppressants and haze-removing agents, contributing to the nation's environmental efforts. Moreover, Laiyu established Shandong Laimei Environmental Technology Co., Ltd. in Binzhou, where it developed China’s first complete set of equipment to convert waste into fertilizers, practicing the circular economy.

　　With a registered capital of RMB 50 million and over 300 employees, the company has a strong R&D team and comprehensive testing facilities. It has established collaborative research partnerships with Beijing Institute of Technology, Soochow University, Qingdao University of Science and Technology, and Beijing University of Aeronautics and Astronautics Materials Research Institute.

　　Laiyu's product portfolio includes magnesium salts such as magnesium sulfate, magnesium acetate, magnesium carbonate, magnesium hydroxide, magnesium chloride, and magnesium acetate; sodium salts including sodium sulfite and sodium metabisulfite; medium-and-trace-element fertilizers and soil conditioners like magnesium fertilizer, calcium-magnesium fertilizer, potassium-magnesium fertilizer, and silicon-calcium-magnesium fertilizer; high-performance organic new materials such as allyl compounds; environmental products like dust suppressants and de-icing agents; and specialty health products. The company also offers customized formulations for certain products, such as liquid magnesium sulfate and potassium-magnesium sulfate. In addition to products, Laiyu provides comprehensive soil conditioning solutions, using new-type fertilizers to remediate soils—successfully achieving significant crop yield increases in “Belt and Road” initiative projects. Driven by innovative technology, Laiyu develops environmental products, undertakes environmental engineering projects, and implements circular economy practices.

　　Laiyu's products are exported to more than 110 countries and regions, with the largest market share in China and a strong presence in the high-end international market. The company holds REACH EU registration and FAMI-QS certification, as well as ISO 22000 Food Safety Management System certification, KOSHER, HALAL, feed-additive production license for magnesium sulfate, food-additive production license for magnesium sulfate, SEDEX, HACCP, GMP+, and other accreditations.

　　In 2020, Laiyu obtained AEO (Authorized Economic Operator) advanced certification, becoming a customs advanced-certified enterprise.

　　With over 40 years of R&D accumulation and cultural heritage, Laiyu has built a complete magnesium salt industrial chain centered on the circular economy and has achieved remarkable accomplishments. The company has established strategic partnerships with internationally renowned brands across multiple industries, serving as a global supplier to many multinational corporations and over 40 Fortune 500 companies.

　　Laiyu has made significant contributions to standardization work. In 2012, the company participated in drafting the national standard for food-grade magnesium sulfate (GB 29207-2012), and in 2017, it took part in revising the industry standard for industrial magnesium sulfate (HG/T 2680-2017).

　　Laiyu is committed to operating with integrity. The company closely integrates employees' personal development with corporate growth, providing a platform for them to realize their value and continuously improve. As a socially responsible enterprise, Laiyu balances the interests of all stakeholders and works with partners along the value chain to build a shared community for mutual development.

　　Where society needs, the company responds. Laiyu consistently focuses on solving critical social issues through its R&D capabilities and product diversity, delivering greater value to society. It closely links production with customer needs and green environmental protection, wholeheartedly contributing to the sustainable development of both enterprises and the environment, as well as to the prosperity of employees, families, and cities.
