Clean Copper Concentrate CIF China

  • Spot liquidity picks up as more offers around
  • Market remain mixed


Platts assessed the CIF China clean copper concentrate treatment charge and refining charge at minus $238/mt and minus 23.8 cents/lb, respectively, on Oct. 9, down $3/mt and 0.3 cent/lb, respectively, from Oct. 8.

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

Platts assessed producer-to-trader copper concentrates TC/RC differentials at minus $82/mt and minus 8.2 cents/lb, respectively, on Oct. 9, down by $2/mt and 0.2 cent/lb, respectively, from Oct. 8.

More offers heard for November-loading shipments after the holiday in China.

“Traders may have pressure to declare a discharging port for November loading shipments; there are more offers after the holiday,” a Chinese source said.

Traders were generally asking for bids, instead of an outright offer, amid TC/RCs uncertainties.

“Bids from smelters were at a wide range from index flat to index minus $10s/mt, the market is unstable over the past two days,” a trader said.

A trade done at index minus $15/mt for Q4 loading clean copper concs from trader to smelter, 30,000 mt in total.

A trade was done at an index minus $8 to minus $9/mt for Q4 loading road-transported copper concentrate between trader and smelter, 10,000 mt.

A trade was also heard done at index minus low-$230s/mt for Q4 arrival clean copper concentrates during the week of Oct. 2, 40,000 mt to 60,000 mt in total.

Some traders delayed the November-loading shipment to December due to the relatively quiet demand for the November-loading shipment.

Reduced usage of copper concentrates is still ongoing, and the smelters are sourcing substitutes to avoid restocking copper concentrates.

“There is no improvement on sulfuric acid prices, and production losses are happening to every smelter,” a trader commented slow restocking from smelters, and felt that TC/RCs would be relatively stable in the short-term.

Another trader said that they still prefer to sell on an index basis despite the discount having narrowed, and smelters refraining from restocking is temporary for the November-loading shipment only.

A tender was heard for 2027 loading Red Chris for 40,000 mt in total, bid due on Oct. 16.
