HS 2846.90Metals

HS Code for Samarium (HS 2846.90)

Samarium is a light REE used mainly in SmCo (samarium-cobalt) permanent magnets - which retain magnetism at up to 350 degC (vs 150-200 degC for NdFeB). SmCo dominates aerospace, defence (missile actuators, satellite reaction wheels), and some medical devices. April 2025 China export permit covers Sm along with Dy/Tb/Gd/Lu.

Frequently asked questions

SmCo vs NdFeB for defence?

SmCo has higher temperature stability (350 degC vs 200 degC), better corrosion resistance, and higher radiation tolerance - critical for missile seekers, tactical radar, and space actuators. NDAA Section 844 restricts DoD from procuring Chinese-origin SmCo/NdFeB from 2027; drives US/Australian supply-chain investment.
