Import Tips
• Verify power rating certification (≤650 kVA) and dielectric type (liquid) via manufacturer specs to confirm 8504.21.00 classification
• Obtain NEMA standards compliance docs; common pitfall is misclassifying dry-type units
• Include test reports for oil insulation to avoid customs holds on safety grounds
