Import Tips
• Provide frequency response test data proving high-frequency design, distinguishing from audio or low-frequency cores
• Label with amorphous alloy composition percentage, as alloy content affects duty calculations and origin rules
• Ship in anti-corrosion packaging; surface damage often leads to rejection as unfit for transformer incorporation
