Neodymium Disc Magnets N52
High-strength neodymium-iron-boron (NdFeB) disc-shaped permanent magnets made primarily of metal alloys, grade N52 for maximum magnetic strength. These are supplied in unmagnetized form intended for magnetization after import and used in motors, sensors, and holding applications. Classified under HTS 8505.11.00 as metal articles intended to become permanent magnets after magnetization.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily ceramic or ferrite composition
Ferrite magnets fall under non-metal permanent magnets in 8505.19
If imported as assembled electric motor component
Complete motor stators with embedded magnets classify under electric motors
If as replacement parts for magnet assemblies
Parts of permanent magnet articles go to 8505.90

Import Tips & Compliance
• Verify metal composition exceeds 50% by weight and obtain magnetization certification if pre-magnetized to avoid reclassification
• Include material safety data sheets (MSDS) for rare earth elements; ensure RoHS compliance for electronics applications
