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
