Copper Cathodes
Copper cathodes are 99.99% pure electrolytic copper plates, the final product of copper smelting and refining. They are the primary traded form of refined copper, used as feedstock by wire rod mills, brass mills, and foundries. LME Grade A cathodes are the global benchmark.

What moves Copper Cathodes pricing
Copper cathodes price as LME 3-month copper plus a physical premium (the 'Yangshan premium' for China, 'Rotterdam premium' for Europe, 'CME Comex' for US). The LME-Comex arb opens periodically, pulling cathodes between regions. Demand is dominated by Chinese power-grid construction, EV motor windings, and renewable energy infrastructure. Supply concentration is extreme: Chile, Peru, and the DRC produce most of the world's cathode-grade material. Strikes at Escondida, Chuquicamata, or Las Bambas can move LME by 5% in days.
How Copper Cathodes cargoes are priced and settled
Standard cathode cargoes are 25 tonnes per container, often shipped as bundled 25-tonne lots. CIF and FOB common, with annual contracts pricing as LME monthly average plus premium and quotational period at buyer's or seller's option. Brand approvals matter: only LME-registered Grade A brands trade at the headline premium. Off-warrant and non-LME-approved brands trade at meaningful discounts.
Copper Cathodes specifications and dispute practice
Grade A cathode (LME spec, 99.99% Cu) is the tradeable standard. Disputes commonly involve oxygen content (pitch and luster), surface oxidation (especially after long warehouse storage), and sulfur. Quality-arbitration LME warehouse rules govern the cure period for off-spec cathodes. Brand discounts can be sticky: a cathode brand that loses LME registration may trade at $50-100/tonne discount for years.
Where Copper Cathodes comes from and where it goes
Top exporters: Chile (Codelco, BHP Escondida, Antofagasta), Peru (Antamina, Cerro Verde), DRC (Glencore, Ivanhoe), Zambia. Top importers: China (refined copper imports run 3-4 Mt/year), South Korea, Taiwan, Japan, Germany, and increasingly the US for grid investment. Concentrate flows separately and prices off TC/RC (treatment and refining charges): the smelter margin.

- Copper Wire RodCopper wire rod is a semi-finished product manufactured by continuous casting and rolling of refined copper. It is the starting material for electrical wire, cable, and conductor manufacturing. Wire rod quality is defined by oxygen content, with oxygen-free copper (OFC) commanding premium pricing.
- Copper ConcentrateCopper concentrate is a semi-processed ore product containing 20-40% copper, produced by crushing, grinding, and flotation of copper-bearing rock. It is the primary feedstock for copper smelters worldwide. Treatment and refining charges (TC/RCs) are a key element of pricing negotiations.
- Copper ScrapCopper scrap is recycled copper sourced from electrical cables, plumbing, demolition, and manufacturing off-cuts. Classified by ISRI codes (e.g., Birch for No.1 bare bright, Candy for No.2 copper), it accounts for roughly 30% of global copper supply and is critical for sustainable metal production.
- Aluminum IngotsAluminum ingots are cast blocks of primary aluminum produced from smelting alumina via electrolysis. They are remelted by foundries and fabricators to produce automotive parts, construction materials, and consumer goods. Standard ingots are 99.7% purity, traded at LME prices plus regional premiums.
- Aluminum BilletsAluminum billets are solid cylindrical logs produced by continuous casting, used as feedstock for extrusion presses to create profiles for construction, automotive, and industrial applications. Alloy grades like 6063 and 6061 dominate the market, with billet diameter typically ranging from 127mm to 406mm.
- Aluminum ScrapAluminum scrap is recycled aluminum collected from beverage cans, automotive components, construction debris, and manufacturing residues. Secondary aluminum production from scrap uses 95% less energy than primary smelting, making it a critical sustainability feedstock. ISRI codes (Taint/Tabor, Tense, Twitch) classify quality.
