Copper

Copper cathode enquiries are defined by the requested grade, impurity framework, physical form, producer evidence and lot-specific inspection documentation. Public references guide the review; the commercial specification is confirmed only with the quotation.

Copper wire rod is a continuous-cast and rolled feedstock for electrical drawing operations. Procurement review focuses on copper grade, diameter, surface condition, conductivity-related requirements, coil mass and producer test evidence.

Copper ingots and refinery shapes are remelt feed for foundry and alloy production. The quotation must identify the shape, copper basis, controlled residual elements, unit weight and the evidence linking each lot to its producer.

Copper concentrate is traded on a dry-mass and payable-metal basis, with penalties and logistics governed by the complete assay rather than copper content alone. Sampling, moisture determination, transportable moisture limit and independent inspection terms are central to the contract.

Copper scrap is purchased by defined scrap class, physical preparation and recoverable-metal basis. A useful enquiry separates bare copper, alloyed material, insulated cable and mixed residues and states contamination, radiation and waste-shipment controls.
