China produces over 85% of the world’s neodymium magnets. And China represents 69% of global rare earth element mining in 2025, with this share increasing towards 90% moving downstream through rare earth separation, metallization, and magnet production stages. So if you’re sourcing NdFeB magnets for motors, sensors, or any industrial application, odds are you’ll end up working with a China magnet company at some point. But here’s the thing: there are thousands of suppliers out there. Some unethical suppliers pass off low-grade magnets as high-grade to increase profits. Getting it wrong doesn’t just waste a purchase order. It can stall your production line for weeks. This guide is what we wish someone had handed us on day one. Why China Still Dominates NdFeB Magnet Supply It’s not just about low prices anymore. China’s magnet industry has matured with modern manufacturing technology, competitive pricing, and wide-ranging customization capabilities. From prototyping to large-scale production, suppliers can meet diverse requirements while maintaining consistent quality, and experienced exporters and reliable supply chains make international sourcing more efficient. 5 Things to Check Before Signing a Contract 1. Are They a Real Manufacturer? This trips up more buyers than anything else. Buyers should source directly from […]
