Fire-Refinery Anode Scrap
Scrap copper anodes returned from fire refining operations, containing 95-98% copper with slag inclusions. HTS 7402.00.00.00 covers this unrefined copper material destined for re-melting and electrolytic refining. Typically briquetted or as-is for furnace feed.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing significant alloying elements per subheading notes
Copper waste/scrap with defined alloy compositions (brass, bronze) classifies under 7404 alloy scrap.
If predominantly slag with copper recovery value only
Slag/ash from refining with copper content treated as mineral residues under Chapter 26.
If contaminated with ferrous materials exceeding 2%
Ferrous scrap containing copper falls under iron/steel waste classification.

Import Tips & Compliance
• Submit spectrographic analysis confirming copper content below refined thresholds (under 99.25%)
• Provide recycling loop documentation showing material flows back to electrolytic refining
• Segregate from copper alloy scrap; alloying elements change classification to Chapter 74 alloy headings
Related Products under HTS 7402.00.00.00
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 falls under HTS 7402.00.00.00 as unrefined copper not suitable for direct use without further processing. This material is typically used as feed for fire refining processes.
Copper Cliff Anodes
Copper Cliff anodes are cast copper shapes produced from smelter matte, used directly in electrolytic tank houses for refining. Classified under HTS 7402.00.00.00 as copper anodes specifically for electrolytic refining. These anodes dissolve during electrolysis to deposit pure copper cathodes.
Electrolytic Copper Starter Sheets
Thin stainless steel-backed copper sheets used to initiate cathode deposition in electrolytic refining cells. Under HTS 7402.00.00.00 as copper anodes for electrolytic refining when considering the deposited copper layer. These starter sheets become perpetual cathodes after initial deposition.
Cement Copper Nuggets
Nugget-form unrefined copper recovered by cementation from acidic mine drainage waters. Classifies under HTS 7402.00.00.00 as unrefined copper requiring smelting and electrolytic refining. Typical purity 60-80% copper with iron/silica impurities.
Anode Casting Wheel Scrap
Overflow and trim scrap from continuous anode casting wheels in copper smelters. HTS 7402.00.00.00 as unrefined copper anodes material returned to the casting circuit. Contains typical anode impurities (oxygen, sulfur) preventing refined classification.
Blister Copper Buttons
Small button-shaped castings of blister copper from fire refining, serving as test samples or furnace charge. Under HTS 7402.00.00.00 as unrefined copper ahead of electrolytic refining. Typical 98-99% Cu with gas porosity characteristic of blister form.
