Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cast rather than sintered construction
Cast metal magnets of samarium-cobalt use different manufacturing process, classifying separately from powder-sintered.
If for use in laser systems as beam steering components
Magnets integral to optical instruments classify with the complete article under Chapter 90.
If containing windings as electromagnetic clutches
Devices combining permanent magnets with electromagnetic coils shift to electromagnetic couplings classification.

Import Tips & Compliance
• Obtain supplier's coercivity (BHmax) specifications; values >28 MGOe confirm premium SmCo grade for proper valuation
• Declare country of melt/refine for samarium; Section 232 tariffs may apply to certain rare-earth origins
• Use protective nickel plating documentation to prevent corrosion claims during ocean transit
