Platts to publish daily calculated outright price assessments for clean copper concentrate producer-trader TC/RCs

Following industry feedback, Platts, part of S&P Global Energy, will launch daily outright price calculations for copper concentrate producer-trader treatment charges and refining charges (TC/RCs), effective July 1, 2026.

Industry feedback has indicated a preference for outright TC/RCs as being more directly reflective of how they are expressed by the market.

The new calculations will reflect the sum of Platts' existing CIF China Clean Copper Concentrate TC/RC assessments and Producer-Trader TC/RC Differentials to them. The CIF China Clean Copper Concentrate TC/RC assessments reflect the market-clearing price between producers and smelters.

The calculations will use the following formulae:

Calculated Clean Copper Concentrate Producer-Trader TC (CCPTT00) = The existing Clean Copper Concentrate CIF China TC (PCCCB00) plus the existing Clean Copper Concentrate Producer-Trader Treatment Charge Differential (PCCCG00).

Calculated Clean Copper Concentrate Producer-Trader RC (CCPTR00) = The existing Clean Copper Concentrate CIF China RC (PCCCC00) plus the existing Clean Copper Concentrate Producer-Trader Treatment Charge Differential (PCCCH00).

Platts will also backfill the calculations using the formulae above to Dec. 1, 2021, when the Treatment Charge and Refining Charge Differentials were launched.

The calculations will reflect the following specifications:
