Platts extends feedback period for proposed outright price assessments for clean copper concentrate producer-trader TC/RCs

Platts, part of S&P Global Energy, has extended the feedback period for the proposal to launch the Platts outright price assessments for copper concentrate producer-trader treatment charges and refining charges (TC/RCs) to May 15, 2026.

The proposal was published earlier on April 2 and can be found here. The original feedback period ended April 17.

The proposed launch date of June 1 is also revised to July 1, following the extension of the feedback period.

Platts proposes to assess producer-trader TC/RCs' outright prices, following initial market feedback indicating a preference for outright TC/RCs as they are more reflective of spot market dynamics than existing producer-trader TC/RCs differentials.

Assessment Name Quality Quantity Incoterm Timing Payment
Clean Copper Concentrate Producer-Trader Treatment Charge Cu 25%, Au 1g/mt, Ag 80g/mt, S 32%, Fe 28%, Pb 0.1%, Zn 1%, As 0.2%, Sb 0.02%, Hg 2.5ppm, Bi 150 ppm, F 330 ppm Min 5,000 mt CIF North China main ports Loading 1-3 months forward L/C at sight
Clean Copper Concentrate Producer-Trader Refining Charge Cu 25%, Au 1g/mt, Ag 80g/mt, S 32%, Fe 28%, Pb 0.1%, Zn 1%, As 0.2%, Sb 0.02%, Hg 2.5ppm, Bi 150 ppm, F 330 ppm Min 5,000 mt CIF North China main ports Loading 1-3 months forward L/C at sight

With the launch of the outright producer-trader TC/RCs, the differentials would continue to be published under their existing symbols as calculations using the formulae:

Clean Copper Concentrate Producer-Trader Treatment Charge Differential (PCCCG00) = The proposed Clean Copper Concentrate Producer-Trader TC minus the existing Clean Copper Concentrate CIF China TC (PCCCB00)

Clean Copper Concentrate Producer-Trader Refining Charge Differential (PCCCH00) = The proposed Clean Copper Concentrate Producer-Trader RC minus the existing Clean Copper Concentrate CIF China RC (PCCCC00)

Platts would also backfill the price history for the outright price assessments using the formulae above to Dec. 1, 2021, when the Treatment Charge and Refining Charge Differentials were launched.

Platts spot price assessments consider market information reported to Platts and published throughout the day, including bids and offers, transactions, and other indications, as well as any other data deemed relevant to the assessment process.

Market information received before the 4:30 pm Singapore (0830 GMT) timestamp would be considered for the assessment.

A full description of Platts' assessment methodologies can be found here.

Details of Platts' suite of copper assessments can be found here.

The proposed assessments would be published in Platts Nonferrous Metals Alert on pages MTL/PMA0304, in Platts Metals Daily, and in the Platts price database.
