Amorphous Metal Laminations for Energy-Efficient Transformer Cores from Japan
Thin amorphous metal alloy ribbons cut into laminations for stacking into high-efficiency distribution transformer cores. These offer lower core losses than traditional silicon steel. Specifically covered by HTS 8504.90.96.34 for transformer stacked core laminations.

Import Tips
• Provide material safety data sheets confirming amorphous metal alloy composition (Fe-Si-B)
• Include efficiency certification or DOE compliance docs for energy-efficient transformer applications
• Ensure packaging prevents ribbon edge damage during transit, affecting core performance
