Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is in the form of billets rather than wire-bars.
Billets are a separate unwrought refined copper form under the same subheading.
If the copper is not refined (e.g., contains impurities above refined copper limits).
Other unwrought refined copper products not elsewhere specified.

Import Tips & Compliance
• Ensure the copper content meets the definition of refined copper (≥99.85% by weight) to qualify for this tariff item
• Provide a mill certificate or assay report to the CBSA to support classification
• Verify whether the wire-bar ends are simply tapered or worked; if worked beyond simple tapering, it may be classified elsewhere
