Millberry copper wire scrap for industrial buyers

ISRI defines Barley as 'bare, uncoated, unalloyed copper wire, not smaller than No. 16 B&S wire gauge, free of burnt wire which is brittle.' In practice this means clean wire of 1.6 mm diameter or greater, with no green corrosion, no tin coating and no insulation residue.

Wire below 1.6 mm or that includes very fine telecom wire is classified as Berry, not Barley, and trades at a small discount even though both look similar.

Most Millberry in Kenyan and Tanzanian are produced by mechanical wire chopping plants that strip insulation from end-of-life cable and recover bare copper. The cleanest output comes from single-source feedstock (e.g. one specific cable type from a known utility) processed on modern cable granulators with optical and density sorting.

Lower-quality Millberry can also be assembled by hand-stripping smaller volumes at scrap yards, but the quantity is rarely enough for export-scale lots.

Millberry is shipped in jumbo big-bags (1,000 kg each), in steel drums or bundled. A 20GP container typically carries 22–24 MT, while a 40HC carries 25–27 MT before reaching the cargo weight cap.

Because copper is dense and heavy, container weight always limits the load before volume does. There is no economic case for under-stuffed Millberry containers.

Genuine Millberry delivers 97–99% metallic yield. Losses are limited to small surface oxidation and minute insulation traces missed by the granulator. Smelters and refineries pay near-LME because this material can go directly into the converter or anode furnace without significant pre-treatment.

Material falsely sold as Millberry but containing 5% Birch-Cliff or insulation residue immediately drops yield to 92–94%, which destroys the buyer's margin.

SGS or Bureau Veritas pre-shipment inspection is standard. The inspector checks: average wire diameter, uniformity, absence of tinning, absence of green oxidation, absence of insulation flakes, and a sample melt to confirm copper purity above 99%.

For large contracts a customer's own QC representative may attend loading. We welcome this — clean Millberry has nothing to hide.

Millberry is quoted at 96–98% of LME copper cash settlement, CIF Asian or Middle Eastern port, in USD. The LME reference is usually the cash settlement on the booking day or an agreed average around the bill of lading date.

A quote significantly below 96% LME signals either a different grade or a financially distressed seller — both are reasons for additional due diligence.

Indian copper rod plants, Chinese refineries (through approved import licences), Vietnamese smelters and Turkish brass-and-rod manufacturers are the largest 2026 buyers of Kenyan and Tanzanian Millberry. Each market has slightly different documentation and inspection requirements, which we manage on the buyer's behalf.
