Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If composed primarily of ferrite oxides
Oxide-based magnets like ferrites have their own subheading, excluding metallic rare-earth alloys from 'other'.
If of Alnico composition
Alnico (aluminum-nickel-cobalt) magnets have a distinct subheading within the 'other' permanent magnets category.

Import Tips & Compliance
• Provide alloy certificates proving SmCo composition to distinguish from cheaper ferrite alternatives during customs review
• Declare intended end-use (e.g
• aerospace) in documentation to support classification and potential duty exemptions
• Ensure packaging prevents corrosion, as oxidation can lead to reclassification or rejection at entry
