What Copper Wire Scrap Grades Mean
Copper wire scrap is classified into grades based on purity, insulation, and oxidation. For importers, understanding these grades is essential because the grade directly determines the recovery yield at the smelter and therefore the price you should pay. The most widely traded grade in the international market is Millberry, but several other classifications appear in supply contracts.
Millberry Copper (Bare Bright)
Millberry refers to clean, bare, uncoated copper wire of 99.99% purity, free of insulation, paint, and excessive oxidation. It is the highest-value scrap grade because it requires minimal processing before melting. Our copper wire scrap is supplied as 99.99% Millberry, making it suitable for direct melting by smelters and manufacturers.
Birch and Cliff Grades
Birch/Cliff is a mixed grade that may include slightly oxidised or smaller-gauge copper wire. It carries a lower recovery rate than Millberry and is priced accordingly. Buyers should always confirm whether a quoted price refers to Millberry or a mixed grade, as the difference materially affects landed cost.
Why Grade Verification Matters for Importers
Before committing to a shipment, request sample photos, specifications, and ideally an independent inspection. A reputable supplier will document the grade clearly. Buyers in markets such as Germany, China, and the USA typically require consistent Millberry grade for their recycling operations.
Factors That Affect Copper Scrap Pricing
Scrap pricing tracks the London Metal Exchange copper price, adjusted by grade recovery rate, volume, and logistics. Higher-purity Millberry commands a premium, while mixed grades trade at a discount. Bulk recurring orders generally secure better terms.
