C11000 Copper Prices November 2, 2026

 The shape in that chart is the whole story of this week. Copper broke downward; the mill quotes barely flinched. Plate, which carries the highest metal share of any C11000 form, gave back $0.06/lb against a $0.125/lb move in the metal. Tube, which is barely half metal, gave back $0.03. If you were waiting for the LME drop to show up on your quote, it has not arrived yet - and the reason is mechanical rather than commercial, which is good news, because mechanical means predictable.

C11000 is electrolytic tough-pitch copper - ETP. It is copper refined electrolytically to 99.90% Cu minimum and then cast in a way that deliberately leaves a small, controlled amount of oxygen in the metal: 0.02–0.04%, present as cuprous oxide (Cu₂O). That oxygen is not contamination. It is what makes ETP the cheapest high-conductivity copper you can buy, and it is also the single reason C11000 cannot be brazed or welded in a hydrogen-bearing atmosphere. Everything a buyer needs to know about this grade follows from that 0.03%.

The melt move this week was −$0.125/lb. The C11000 plate quote moved −$0.060/lb. Here is the full arithmetic, line by line, in USD per lb of finished plate.

Two of those lines are temporary and one is permanent, and telling them apart is the whole decision. The premium catch-up and the high-cost inventory are both decaying - they unwind on their own within four to six weeks. The conversion line is not: it will not move unless mill order books thin out. So the $0.065/lb still owed to you is real, it is dated, and it arrives in December.

On a 5,000 lb plate order that is $325. On a 20,000 lb annual busbar programme it is roughly $1,300. That is worth a conversation, but it is not worth a line stoppage, so here is the decision rule.

The Wait-Or-Buy Rule For This Week

If your next consumption is more than eight weeks out: split the order - 60% now, 40% in December. You collect the pending $0.065 on the back half without running your line dry.

If you are inside six weeks: buy now. The $325 on a 5,000 lb order does not cover one day of downtime, and thin-gauge strip and seamless tube are not going to give you the drop anyway.

Watch the Midwest premium, not the LME ticker. When the premium rolls over, the full decline has worked through the chain. That is your signal, and it arrives before the quote does.

Cumulative move is now −2.70% from the October 19 high. If your supply agreement carries a reset trigger - commonly LME moving more than 3–5% from the order date - you are close. For December deliveries, ask for metal-price-at-shipment instead of a fixed price; that clause is precisely what captures the pending $0.065.

Before you wait for copper to fall further, check how much of what you are buying is copper. On seamless tube it is barely half, which means waiting on the LME is close to pointless for tube buyers - the conversion leg and mill capacity set that price.

Read that table alongside the snapshot and the week resolves cleanly. The two forms that fell least - thin-gauge strip at −$0.04 and seamless tube at −$0.03 - are the two forms with the lowest metal share. They are priced off rolling capacity and cleaning and drawing line availability, and the Q4 book for both is still full. Copper falling 1.90% simply is not the variable that moves them.
