Import Tips
• Declare phase configuration, core weight, and B-H curve data to differentiate from single-phase or non-transformer cores during inspection
• Ensure compliance with IEEE transformer standards; non-conforming cores risk seizure as safety hazards
• Use HTS advisory rulings for high-value shipments over 500kg to preempt valuation disputes on material content
