About
Built from two years inside the copper trade
From late 2024, our founder, Xavier Williams, worked as a broker in physical copper: cathode, concentrate, ore and scrap from the DRC, Zambia, Tanzania and Mozambique, for buyers in China, the UAE, India, Turkey and Europe. The work happened where the trade happens: on WhatsApp, LinkedIn and email, in bonded warehouses and at smelter gates.
There were hundreds of conversations, and very few signed contracts. Looking back over every message, the reasons were almost never the copper itself. Payment terms that could never meet. Buyers asking for prices no real seller could give. Chains of brokers, none willing to name their principal. Forged certificates of origin, recycled warehouse receipts and warehouses that only existed online.
And through all of it, people on every side kept asking for the same thing: proof that the other side is real.
So that is what Copper Supply is built around. The marketplace is free, because buyers and sellers should be able to find each other without a toll. What we charge for is trust: checking people and companies, checking documents, and due diligence on counterparties. Those services are useful whether or not a cargo ever moves, which means we have no reason to push anyone into a deal.
How we work
Six things we hold ourselves to
We never hold trade money
We are not a party to your deal and never take custody of funds or goods. That keeps us honest, and keeps your money between you, your counterparty and your banks.
Badges say exactly what was checked
Every badge names the level, what was checked and the date. It never claims more, and it expires.
No invented numbers
No made-up member counts, views, deal volumes or testimonials. If a number isn't real, we don't show one.
Producers are verified free
Genuine mines and plants are the scarce side of this market. We pay for their verification so buyers can find them.
Plain words, built for phones
Many traders read English as a second language and work from a phone on slow data. Every screen is written and built for that.
Your documents stay private
Files are private until you share them, and open only through links that expire in minutes.
