Smelter Anode Turnings
Smelter anode turnings are machining turnings from anode straightening operations in copper smelters. They are unrefined copper scrap requiring remelting and electrolytic refining, with typical anode impurities preventing direct use.

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.
