Copper cathode · verified sellers
Copper cathode suppliers are smelters, refineries, SX-EW mines and the traders who buy from them. A real seller can name the producer and brand, show where the copper is today and accept independent inspection. On Copper Supply every member passes an ID check before they can message you, and you can post a free requirement so sellers come to you.
A real seller can answer four questions without delay: who produced the copper, which brand it is, where it is today, and who owns it. Most real African cathode sits in a named bonded warehouse, at a smelter gate, or on the road to Dar es Salaam, Durban, Walvis Bay or Lobito.
Real sellers price against the LME and can explain their discount or premium: incoterm, location, payment terms and volume. They offer a quantity they can load, often a few hundred tonnes a month to start, not 50,000 MT a month from day one.

Post a buying requirement with your grade, tonnage, incoterm, location and payment terms. It is free. When it goes live, members who sell cathode get an email within minutes, and every Monday all members see it in the market report. Sellers ask for an introduction, you see their profile and what was checked, and you choose who to talk to.
Free to join. Copper Supply never holds trade money and takes no commission on deals.
Against the LME cash settlement price, averaged over an agreed period. Registered Grade A brands in main markets sell at LME plus a premium in US$ per tonne. Non-registered brands and cathode sold inland in Africa sell at a discount to the LME, which covers transport, finance and brand risk.
Grade A is refined copper cathode that meets BS EN 1978 Cu-CATH-1, ASTM B115 Grade 1 or the matching Chinese standard, typically quoted as 99.99% copper. Brands that meet it and are approved by the LME can be delivered against LME contracts. Cathode that meets the chemistry but is not an LME brand is often called non-registered or off-brand.
A real seller can name the producer and brand, prove where the copper is and who owns it, and accept an inspector you appoint. Check the company in its official registry, call the warehouse yourself on its published number, and have the documents reviewed. A price deeper than about LME −20% is a strong sign the offer is fake.
Rod mills, wire and cable makers, brass and tube mills, and the trading houses that supply them. China is the largest importer of refined copper, followed by countries such as India, Turkey, South Korea, Taiwan and Italy.

Typical copper cathode specification
Usually an SCO or FCO from the seller, an LOI or ICPO from the buyer, then an SPA. Delivery needs a certificate of analysis, independent inspection, a warehouse receipt, an export licence, certificates of origin and a bill of lading or road consignment note.
Almost never for Grade A. In 2025 and 2026 real cathode in African bonded warehouses traded at roughly LME −8% to −10%. Any trader could buy real Grade A at −20% and sell it on at once, so such offers are used to collect contacts, documents or fees.
