Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polymer-bonded rather than sintered metal
Bonded samarium-cobalt magnets using plastic binders classify under 'flexible' permanent magnets of heading 8505.19.
If imported as unmagnetized sintered blocks for custom machining
Articles intended to become magnets after further processing may fall under parts of permanent magnets.
If when incorporated into finished industrial machinery valves
Magnets as integral parts of classified machinery take the machinery's tariff heading per GRI 2(b).

Import Tips & Compliance
• Include alloy composition analysis reports; U.S
• Customs may test for samarium content to distinguish from cheaper alternatives
• Label as 'not for consumer sale' if industrial grade to avoid potential toy safety regulations under CPSIA
• Check for anti-dumping duties on Chinese-origin rare-earth magnets through Commerce Department scopes
