HS Code for Dysprosium (HS 2846.90)
Dysprosium is the most strategically critical heavy rare earth - added at 0.5-6% to NdFeB magnets to raise coercivity at 150-200 degC (essential for EV traction motors, wind turbine generators, aerospace actuators). China's April 2025 export permit on Dy/Tb/Sm/Gd/Lu magnet materials pushed magnet supply chain into acute risk mode.

Frequently asked questions
NdFeB magnets lose coercivity above 80-100 degC. EV traction motors run at 150-180 degC. Adding 3-6% Dy (grain-boundary diffusion or bulk) raises intrinsic coercivity from ~1000 kA/m to ~2500 kA/m. Without Dy (or partial Tb substitute), NdFeB magnets thermally demagnetise in service.
