Amorphous Metal Stacked Transformer Core from China
Stacked laminations made from amorphous metal alloy (metglas) optimized for low-loss distribution transformers. These cores are pre-cut and interleaved for direct incorporation into transformer manufacturing processes. HTS 8504.90.96.38 applies to such unfinished stacked cores destined for transformer assembly.

Import Tips
• Provide material safety data sheets confirming amorphous alloy composition, as these differ from crystalline silicon steel and affect efficiency claims
• Label shipments clearly as 'transformer stacked cores - not for resale as finished goods' to prevent misclassification as complete transformers
