Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copper is alloyed (e.g., with silver or other elements above limits)
Copper alloy plates/sheets/strip are classified under subheading 7409.19.
If the product is in bar or rod form rather than plate/sheet
Bars and rods of refined copper fall under heading 7407.
If the product is drawn into wire for busbar connections
Wire of refined copper with cross-section up to 6 mm falls under heading 7408.

Import Tips & Compliance
• Provide a certificate of analysis confirming ETP copper composition (≥99.9% Cu) to support refined copper classification
• Note that busbar applications may require additional electrical safety certifications
• Keep records of the coil's dimensions for CBSA verification
