Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the width is 600 mm or less
Narrower grain-oriented silicon-electrical steel is classified under heading 72.26.

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
• Provide technical datasheets showing the steel's silicon content (0.6%–6%) and carbon content (≤0.08%) to confirm silicon-electrical steel classification
• Ensure the width is documented as over 600 mm; products at or below this threshold fall under a different tariff item
• Be prepared to explain the domain refinement process if CBSA requests additional classification details
