Import Tips

Provide heat treatment specs and Curie temperature data to confirm high-temp suitability under metal magnet classification

ITAR/EAR export control checks required for defense applications; declare cobalt content accurately

Avoid bulk packaging that resembles scrap, which could shift to 8549.11 spent battery materials
