LME Grade A copper cathode at 99.99% copper to BS EN 1978 Cu-CATH-1. Full impurity assay on every Mill Test Certificate, priced on LME plus premium with quotational period agreed in writing.
LME Grade A is the copper cathode benchmark, corresponding to BS EN 1978:1998 Cu-CATH-1 and broadly equivalent to ASTM B115 Grade 1. It is not simply "99.99% copper" — it sets ceilings on individual impurity elements, because certain traces degrade conductivity and hot-working far out of proportion to their concentration.
Request the Mill Test Certificate showing the actual assay against these limits, not a supplier statement that material is "99.99% pure". A cathode meeting overall copper content while breaching the bismuth or selenium ceiling will cause wire breaks at the drawing stage.
Copper is exchange traded. Every credible offer is structured as LME price plus a premium, and buyers new to copper sometimes compare a fixed-price offer against an LME-linked one and reach the wrong conclusion.
Agree the quotational period in writing before the order is confirmed. Two offers with identical premiums but different QPs are not the same offer — in a volatile market the QP moves landed cost more than the premium does.
On specifications: the figures above reflect standard industry specifications for this product. Your actual batch values are confirmed on the Mill Test Certificate or Certificate of Analysis issued against your specific lot — provided with every shipment, and with sample orders before you commit to bulk. We do not ask buyers to take a specification on trust.
Copper is high value per container and independent verification at load port is standard rather than optional.
HS Code 7403.11. RoHS declaration available on request for European electrical supply chains.
MOQ is discussed at order stage. Pricing on LME plus premium with QP agreed in writing. Payment by advance TT, LC at sight, or DP/DA case by case.
It is the copper cathode quality standard set by the London Metal Exchange, corresponding to BS EN 1978:1998 Cu-CATH-1 and broadly equivalent to ASTM B115 Grade 1. It requires minimum 99.9935 percent copper with strict ceilings on individual impurity elements. Only cathode from LME-registered brands may be delivered against LME contracts.
Because certain trace elements degrade performance out of all proportion to their concentration. Bismuth above 2 ppm causes hot-shortness during rod casting. Selenium, tellurium and bismuth together above 3 ppm cut conductivity and ductility. A cathode can meet overall copper content and still breach one of these ceilings, causing wire breaks at the drawing stage.
As LME cash settlement price plus a fixed premium in dollars per tonne. The premium reflects destination, quantity and delivery terms. Agree the quotational period in writing before the order is confirmed, because two offers with identical premiums but different averaging windows are not the same offer, and in a volatile market the QP moves landed cost more than the premium does.
Refined copper cathodes and sections of cathodes are exported under HS Code 7403.11. Copper wire rod falls under 7407.10. We declare the correct code on all shipping documents.
Yes. Copper is among the highest value commodities by container, and independent sampling and assay at load port by SGS, Bureau Veritas or Intertek is standard practice rather than an optional extra. It covers weight verification, sampling, chemical analysis and packing condition before the cargo sails.
