Clean Copper Concentrate CIF China

Some smelters pay lower TC/RC for urgent demand

Wide gap between bids and offers on fixed TC/RC basis


Platts assessed the CIF China clean copper concentrate treatment charge and refining charge at minus $58.10/mt and minus 5.81 cents/lb, respectively, on March 6, down 90 cents/mt and 0.09 cent/lb from March 5.

Tradable values were heard at minus $55/mt on an M+1 or M+5 pricing basis at the seller's option for May-loading clean copper concentrates, from trader to smelter, normalized to minus 58.10/mt on an M+3 basis.

Platts assessed producer-to-trader copper concentrates TC/RC differentials at minus $45.90/mt and minus 4.59 cents/lb, respectively, on March 6, down $2.30/mt and 0.23 cent/lb from March 5.

Some smelters were still looking for March loading clean copper concentrates, while many are sourcing April cargoes.

“Especially some small-sized smelters, who are less covered by term contracts, are willing to pay lower TC/RCs to fix a spot cargo,” a seller said.

A trade was done at around minus $60/mt between the producer and the smelter for April loading of clean copper concentrates.

A firm offer heard at minus $58/mt from a trader to a smelter for April loading clean copper concentrates.

“I think smelters were not ready to pay the same TC/RC to traders compared to producers,” a trader said.

Offers for a larger volume were heard at minus low-$60s/mt from trader to smelter, while smelters felt it was difficult to accept minus $60s/mt at the moment.

“It is really difficult to negotiate a fixed TC/RC nowadays, so many contracts were booked on an index basis,” a procurement source said.

Bids heard at minus low-to-mid-$50s/mt from smelter to trader for April loading clean copper concentrates.

According to traders, spot TC/RCs were still on a downtrend, and they were flexible to sell on a floating basis for spot contract.

About 20,000 mt to 30,000 mt clean copper concentrates were heard done on an index basis for March loading, producer to smelter, M+3 pricing.
