Copper Wire Scrap Millberry Supplier
Copper Wire Scrap Millberry Overview
Copper wire scrap millberry is the highest-grade classification of copper scrap, consisting exclusively of clean, uncoated, unalloyed copper wire free from insulation, paint, tinning, plating, and excessive oxidation.
It is classified under ISRI code “Birch” defined as clean, untinned, uncoated, unalloyed copper wire and cable and is graded as Electrolytic Tough Pitch (ETP) Grade C11000, the same specification used for primary copper wire production.
The material originates primarily from the recycling of pure copper electrical wiring, telecommunications cable, and industrial conductor offcuts, and is processed through modern electrostatic separation and optical sorting systems that have improved purity recovery rates significantly.
Because copper millberry delivers copper content equivalent to primary cathode at substantially lower cost typically 20–30% below virgin copper pricing it is the preferred secondary feedstock for brass mills, copper rod drawing operations, and secondary smelters seeking high-purity, cost-effective raw material for refined copper product manufacture.

Copper Wire Scrap Millberry Suppliers FAQ
Copper wire scrap millberry is the highest-grade classification of recycled copper scrap, consisting of clean, uncoated, unalloyed copper wire free from insulation, paint, tinning, and foreign attachments. It is classified under ISRI code “Birch” and graded as Electrolytic Tough Pitch (ETP) C11000, with copper content of 99.95%–99.99%. It serves as a direct substitute for primary copper cathode as a secondary feedstock in copper rod, cable, and alloy manufacturing.
Commercial copper wire scrap millberry carries a minimum copper content of 99.95%, with premium grades reaching 99.99%. Key impurities including iron, lead, bismuth, zinc, phosphorus, and sulphur are each maintained at or below 0.005%, ensuring the material meets the intake specifications of copper rod mills, brass mills, and secondary smelters. Purity is confirmed by independent SGS Certificate of Analysis per shipment lot.
Millberry copper (ISRI “Birch”) is the highest-grade copper scrap, consisting solely of clean, bare, uncoated, unalloyed copper wire at minimum 1.2mm gauge with no attachments. Number 1 copper scrap (ISRI “Berry”) may include unalloyed copper pipe, solids, and wire but permits a wider range of forms and minor surface oxidation. Millberry commands a higher price and is preferred by rod mills requiring cathode-equivalent purity without additional processing.
Millberry scrap is supplied as hydraulically compressed bales or loose material packed into 20-foot or 40-foot ISO containers. Bales are the standard format for most commercial shipments, enabling efficient container loading, handling at processing plants, and density optimisation to minimise freight cost per tonne. Weight certificates and SGS inspection results are issued at the loading point for every shipment.
