Import Tips
• Verify power rating certification from manufacturer to confirm 500-650 kVA range; customs may require test reports
• Include detailed specs on dielectric fluid (e.g
• mineral oil) and voltage ratings in commercial invoice to avoid reclassification
• Check EPA regulations for oil-filled transformers; provide spill containment plans if applicable for U.S. entry
