More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the alloy is not a master alloy but a copper-silicon alloy
Copper alloys not meeting master alloy criteria fall under heading 74.03.
If the cut pieces are further worked into profiles
Worked copper profiles are classified under heading 74.07.

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 silicon content is 10% and the product is not malleable to meet the master alloy definition
• Provide detailed composition data to the CBSA for classification
• Verify if the cut pieces are considered 'unworked' to avoid reclassification under other headings
