Published on September 05, 2026 by MillberryCopper.com Trade Intelligence Desk
Key Takeaways & Summary
Avoid scrap trade fraud. Discover how handheld XRF alloy guns and independent SGS lab assay reports verify 99.9% copper purity before loading 20ft container shipments.
The Hidden Risk of Contaminated or Tinned Copper Scrap
Millberry copper scrap represents the global industry benchmark for clean, unalloyed bare bright copper wire with a minimum purity of 99.9% Cu. When trading under standard ISRI specifications, buyers and refiners calculate pricing directly off live London Metal Exchange (LME) spot rates minus standard smelting and refining discounts.
Industrial processing of copper wire requires strict adherence to physical characteristics: wire diameters must exceed 1.3mm (16 Gauge B&S), with zero presence of tinned coatings, oxide tarnish, or insulation residue. International shipments through major ports like Mundra, Rotterdam, and Jebel Ali utilize 100% Irrevocable Letters of Credit (LC at sight) paired with independent SGS assay testing.
