Commercial Three-Phase Transformer 300 kVA
A 300 kVA three-phase liquid dielectric transformer, mineral oil filled, designed for light industrial use. It converts 480V delta input to 208Y/120V wye output, making it suitable for commercial and industrial power distribution. Its power handling capacity does not exceed 650 kVA, so it falls under tariff item 8504.21.00.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the power handling capacity exceeds 650 kVA but does not exceed 10,000 kVA
Liquid dielectric transformers above 650 kVA are classified under a different tariff item based on capacity.
If the transformer is not liquid dielectric (e.g., dry-type)
Dry-type transformers are classified separately from liquid dielectric transformers.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the transformer meets Canadian Standards Association (CSA) certification for electrical safety
• Declare the correct power handling capacity (kVA) and dielectric type to avoid classification disputes
• Verify if the provincial electrical authority requires additional permits for installation
