Import Tips
• Require manufacturer's test report showing no-load loss, load loss, and impedance values for customs valuation
• Coordinate with utility buyer for site-specific voltage requirements before import to avoid returns
• Declare transportation weight accurately; transformers over 100 tons may need special permits
