Import Tips
• Verify the part is solely for transformers/static converters via manufacturer specs to avoid reclassification as general metal parts
• Include detailed engineering drawings and end-use certificates in documentation to prove HTS 8504 applicability
• Watch for undervaluation pitfalls; cores often require separate valuation from complete units
