Permanent Copper Cathodes
Permanent copper cathodes are stainless steel-framed plates used in electrolytic refining to collect high-purity copper deposits. They are classified as unrefined copper or copper anodes for electrolytic refining under tariff item 7402.00.00, as they are integral to the refining process. The deposited copper layer on these cathodes is considered unwrought copper, falling within this heading.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cathodes are refined copper and not for electrolytic refining
Refined copper cathodes fall under heading 7403, which covers refined copper and alloys.
If the cathodes are waste or scrap, not usable as cathodes
Copper waste and scrap are classified under heading 7404, distinct from unwrought copper anodes.
If the cathodes are part of a machine for electrolytic refining
Machinery of Section XVI may be classified under heading 8479, excluding base metal articles.

Import Tips & Compliance
• Ensure the cathodes are described as unrefined copper or anodes for electrolytic refining to avoid misclassification
• Verify the copper content and purity with a certificate of analysis, as CBSA may request it
• If the cathodes are used in machinery, consider whether Section XVI exclusions apply
Related Products under Tariff item 7402.00.00
Anode Casting Wheel Scrap
Overflow and trim scrap from continuous anode casting wheels in copper smelters. This material is unrefined copper returned to the casting circuit, containing typical anode impurities such as oxygen and sulfur, and is not yet suitable for direct use without further refining.
Black Copper Precipitate
Black copper precipitate is a low-grade unrefined copper produced by cementation from copper-bearing solutions, containing impurities like iron and sulfur. It is not suitable for direct use and requires smelting and electrolytic refining, aligning with the tariff item's scope.
Blister Copper Buttons
Blister copper buttons are small castings of blister copper from fire refining, used as test samples or furnace charge. They are unrefined copper with typical purity of 98-99% and gas porosity, requiring electrolytic refining before use.
Cement Copper Nuggets
Cement copper nuggets are unrefined copper recovered by cementation from acidic mine drainage waters, with typical purity of 60-80% copper. They require smelting and electrolytic refining, fitting the tariff item's scope for unrefined copper.
Copper Cliff Anodes
Copper Cliff anodes are cast copper shapes produced from smelter matte, used directly in electrolytic tank houses for refining. They are copper anodes specifically for electrolytic refining, matching the tariff item's description.
Electrolytic Copper Starter Sheets
Electrolytic copper starter sheets are thin stainless steel-backed copper sheets used to initiate cathode deposition in electrolytic refining cells. The deposited copper layer is unrefined and intended for further refining, aligning with the tariff item.
