Electrolytic Copper Refinery Turnings Scrap
Fine copper turnings and shavings generated during machining of refined copper anodes, with copper assay under 94%. Classified as waste and scrap under HTS 7404.00.30.20 due to refined copper source and low purity from wear. Primarily used in secondary copper smelting.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from alloyed refined copper anodes
Alloy scrap (brass/bronze) from refining has separate statistical reporting even at <94% total copper.
If contaminated with significant iron (>40%)
High-iron copper-bearing scrap classified as ferrous waste under Chapter 72, based on predominant material.
If insulated copper wire turnings rather than anode scrap
Wire scrap with insulation falls under Chapter 85 electrical waste, regardless of copper content.

Import Tips & Compliance
• Submit detailed chemical composition report; turnings often contaminated with oils requiring pre-shipment cleaning certification
• Verify no alloying elements exceed brass/bronze definitions to prevent Chapter 74 alloy scrap classification
