Import Tips
• Verify lamination thickness and insulation coating meet transformer core stacking specifications to avoid reclassification
• Provide manufacturer specs confirming use solely for stacked transformer cores, not wound cores
• Check for steel origin certificates as anti-dumping duties may apply to certain silicon steel imports
