Import Tips
• Obtain manufacturer test reports showing Curie temperature and core loss data for classification support
• For high-volume imports, consider bonded warehouse storage to manage duties on slow-moving inventory
• Distinguish between sendust cores (different HTS) via alloy composition certificates
