Cu-ETP copper rod at 8mm standard diameter, minimum 99.90% copper and 100% IACS conductivity to ASTM B49. Oxygen controlled 200–400 ppm, priced on LME plus premium with conductivity stated on every Mill Test Certificate.
ETP stands for Electrolytic Tough Pitch, designated Cu-ETP or UNS C11000. It is the standard conductor-grade copper rod worldwide. The defining characteristic is controlled oxygen content: enough to scavenge impurities into oxides, low enough to avoid embrittlement.
IACS — International Annealed Copper Standard — is the conductivity benchmark. 100% IACS is the reference conductivity of pure annealed copper; well-produced ETP rod meets or slightly exceeds it. If a supplier cannot state IACS conductivity on the Mill Test Certificate, treat that as a red flag: for wire and cable manufacturers it is the single most commercially important property.
Rod and cathode are different stages of the same supply chain. Buying the wrong one means either paying an unnecessary conversion premium or receiving material you cannot process.
If you operate a continuous cast rod line, buy cathode and avoid the conversion premium. If you draw wire directly from rod, buy rod. Buying rod when you have a rod mill means paying twice for the same conversion.
Copper rod is priced as LME plus a premium, and the premium includes the cast-and-roll conversion cost over cathode.
Agree the quotational period before the order is confirmed. In a volatile copper 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 7407.10 (bars, rods and profiles of refined copper). Coil weight and packing to buyer specification.
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.
ETP stands for Electrolytic Tough Pitch copper, designated Cu-ETP or UNS C11000, with minimum 99.90 percent copper and controlled oxygen between 0.02 and 0.04 percent. It is the standard conductor-grade rod worldwide, supplied most commonly at 8mm diameter for drawing into building wire, power cable, magnet wire and automotive harness wire.
IACS is the International Annealed Copper Standard, the reference conductivity of pure annealed copper. Well-produced ETP rod meets or slightly exceeds 100 percent IACS. For wire and cable manufacturers conductivity is the single most commercially important property, so if a supplier cannot state IACS on the Mill Test Certificate, treat it as a red flag.
If you operate a continuous cast rod line, buy cathode and avoid the conversion premium. If you draw wire directly, buy rod. Buying rod when you already have a rod mill means paying twice for the same conversion, and buying cathode without melting capability leaves you with material you cannot process.
Because ETP copper needs some oxygen. It scavenges impurities into oxides, which keeps them out of the copper matrix and preserves conductivity. Too little and impurities stay dissolved; too much and the copper becomes embrittled, particularly during hot working. The 200 to 400 ppm window is the balance point.
Bars, rods and profiles of refined copper, including 8mm ETP rod, are exported under HS Code 7407.10. Copper cathode falls under 7403.11. We declare the correct code on all shipping documents.
As LME cash settlement plus a premium, where the premium includes both the base cathode premium and an additional conversion premium covering cast and roll. Agree the quotational period in writing before the order is confirmed, because in a volatile market the averaging window moves landed cost more than the premium does.
