Clean Copper Concentrate CIF China

  • Smelters bid lower to fight for clean concs
  • Small-sized smelters were also looking to buy


Platts assessed the CIF China clean copper concentrate treatment charge and refining charge at minus $88/metric ton and minus 8.80 cents/lb, respectively, April 30, down by $1.50/mt and 0.15 cent/lb from April 29.

Platts currently applies zero TC/RC spreads when normalizing M+5 pricing to M+3 for smelters' purchases based on market surveys.

Platts assessed producer-to-trader copper concentrates TC/RC differentials at minus $50/mt and minus 5 cents/lb, respectively, on April 30, down by $1.50/mt and 0.15 cent/lb from April 29.

Despite short-term uncertainties over sulfuric acid prices, smelters maintained positive margins and were keen to restock copper concs, according to a trader.

“Large-sized smelters still face a great shortage, and small-sized smelters were also looking to buy,” a trader said.

A firm offer was heard at minus $95/mt from trader to smelter for June loading clean copper concs.

“Although bids still at minus mid-to-high-$80s/mt, we may see minus $90s/mt get done soon,” the same trader said.

Another trader said that smelters can accept lower TC/RCs for Asia-origin, prompt-arrival clean copper concs to capture the current margin.

“Some smelters who were relying on road-transported and domestic copper concs only operate at 50%,” a second trader said.

Escondida tender heard for June to July loading, M+3 pricing, 10,000 mt, bid due on May 4.

A trader with June-to-July loading shipments on hand said they were not in a rush to sell.

“It is normal to see that traders were waiting for the last minute to offer,” the trader added.

Firm offers remained quite limited relative to smelter demand, and some sellers felt there was still room for TC/RCs to decline further.

Smelters were more interested in bidding a fixed TC/RCs for June to July loading cargoes, “and bids were very conservative for the forward loading months,” a third trader said.

Platts is part of S&P Global Energy.
