How to Test & Verify 99.9% Millberry Copper Scrap Purity (XRF & SGS Guide)
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
International copper shipments risk contamination when tinned, copper-clad aluminum (CCA), or brass-plated strands are inadvertently baled with pure Millberry. Even 0.5% tin or zinc contamination degrades entire smelting batches.
Using Handheld XRF Alloy Guns for Instant 2-Second Yard Testing
Portable X-Ray Fluorescence (XRF) analyzers allow yard inspectors and container loaders to non-destructively verify chemical composition in two seconds. High-precision spectrometers detect copper percentages to two decimal places while identifying trace elements like silver, nickel, and antimony.
Step-by-Step SGS Loading Inspection & Moisture Protocol
For international maritime shipments, independent surveyors like SGS or Alex Stewart draw cross-section composite samples from every container during stuffing. They weigh the cargo on certified weighbridges, verify moisture content, and seal container doors with serialized customs bolt seals.
Protecting Container Payment under Irrevocable Bank LC at Sight
By requiring the original SGS Certificate of Quality and Quantity as a mandatory negotiable document under the Letter of Credit, buyers ensure funds are only debited when the cargo meets exact contracted purity specifications.
