Import Tips

Magnetize post-import if possible to qualify as 'articles intended to become permanent magnets' and defer duty

Comply with ITAR/EAR if destined for defense applications; magnets > certain field strength may be controlled

Batch test for Curie temperature certification (>300°C typical for SmCo) to support high-temp claims
