This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precision machined with mounting holes
Finished articles with features for specific apparatus classify as parts
If pure rare earth compounds before alloying
Chemical compounds of rare earths precede magnet fabrication in 2846
If DC motor armatures containing magnets
Complete electrical machinery takes precedence over components
