Tridus Magnetics and Assemblies
Tridus Magnetics and Assemblies is a Rancho Dominguez, California-based supplier of permanent magnets and custom magnetic assemblies, specializing in sintered NdFeB magnets under its Tri-Neo brand and engineered assemblies fabricated through its wholly owned subsidiary in Beijing — combining cost-effective Chinese production with California-based rapid prototyping, global quality oversight, and ISO 9001-certified quality assurance. The company serves automotive, industrial, and consumer electronics OEMs with a broad range of magnet shapes, sizes, and grades for applications including PMDC motors, Hall effect sensors, EV generators, electric pumps, and power steering systems, and notably became one of the first companies to receive a Chinese Ministry of Commerce (MOFCOM) export license for rare earth magnets following the 2025 export control restrictions — a significant supply chain advantage for its US customers. In July 2025, Tridus was approved by US Customs and Border Protection as a Foreign Trade Zone (FTZ) operator at its Compton, California facility, further enhancing its ability to manage tariff exposure and streamline customs processing for rare earth magnet imports serving North American manufacturers.
