Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If capacity between 1,001-10,000 kVA
Adjacent capacity range uses different statistical suffix.
If imported as refurbished or rewound unit
Used transformers may classify as parts for repair rather than new equipment.
If over 60,000 kVA rating
Higher power handling shifts statistical classification.

Import Tips & Compliance
• 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
