About Us

Yunsheng USA Inc., a subsidiary of the Ningbo Yunsheng Co. Ltd, is focused on developing, manufacturing and marketing high strength, high performance rare earth permanent magnets and magnetic assemblies.   Ningbo Yunsheng Co. Ltd., is located in Ningbo prefecture, the “Silicon Valley of Magnetics” in China, home to 100+ magnet manufacturers.  

Our product quality is assured and recognized worldwide.  We are ISO9001- and ISO14001-certified, and own numerous patents in the magnetics field, including: cast crystallizer and cast strip processes, as well as injection molding techniques.   We also hold the automotive IATF16949 certification, an additional reassurance of our dedication to rigorous quality assurance standards, achieved only by industry leaders.

Yunsheng is a licensed manufacturer and vendor in all patented markets of North America, Europe and Asia.  In 2002, Yunsheng signed a Patent License Agreement with Sumitomo Special Metals Co. for the development, manufacture and sales of licensed NdFeB-type anisotropic, sintered magnets worldwide.  In 2013, Yunsheng renewed its license agreement with Hitachi Special Metals, and remains among an elite group of approved patent licensees.  We are, therefore, able to guarantee that every Yunsheng product is manufactured from our own facilities using licensed materials and certified processes only.  Yunsheng also holds the sublicense to sell NdFeB magnets under Magnequench patents.

For the past two decades, we are the only Chinese magnet manufacturer to maintain a dedicated, USA-based operation for our customers' convenience, outside of China.  This committed investment in infrastructure is to guarantee all our North American customers, personalized customer service and direct factory response while maintaining a very competitive, offshore pricing edge.  Our savings are your profitability!
