Who buys copper cathode

  • Rod mills and cable makers turn cathode into 8 mm rod and wire. They are the largest end users.
  • Brass mills, tube mills and other fabricators buy cathode for sheet, strip, tube and alloys.
  • Trading houses buy at the mine, smelter or warehouse, take the transport and finance risk, and sell on to end users in China, India, Turkey, the Gulf and Europe.
  • Regional traders in the Gulf and East Africa often buy bonded stock at port.

China is by far the largest importer of refined copper. India, Turkey, South Korea, Taiwan, Vietnam and Italy are also large buyers.

What buyers need from you

  • Clear title: your company name on the warehouse receipt or export papers, or a written explanation of the chain
  • Brand and producer, with the certificate of analysis for each lot
  • Location and incoterm, for example FCA bonded warehouse Dar es Salaam or EXW smelter gate Kolwezi
  • Access for their inspector to weigh, sample and assay
  • Legal export: a valid export licence and, for DRC road cargo, one set of papers per truck

Buyers who have been burnt before will ask for a trial of one to three trucks. That is normal. See trial orders.

Payment terms you will meet

  • TT after inspection in a bonded warehouse, with the goods transferred into the buyer's name on payment. Common for trial lots.
  • Letter of credit at sight, often for contracts after the trial. See letters of credit.
  • Cash against documents (CAD) for shipped cargo.

Be careful with buyers who ask you to pay for anything first, or who send "proof of funds" with no bank you can contact. See how to verify a copper buyer.

Questions people ask

How is copper cathode priced?

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.

What is Grade A copper cathode?

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.

How do I know a copper cathode seller is real?

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 run the documents through a fraud check. A price deeper than about LME −20% is a strong sign the offer is fake.

Who buys copper cathode?

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.

What documents are used in a copper cathode deal?

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.

Is copper cathode at LME −20% real?

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.
