Sources: China's smelter group does not set Q4 copper TC/RC guidelines

Sources said that China's leading copper smelters have decided not to set fee guidance for copper concentrate processing in the fourth quarter of 2025. This is the third time in a row they have taken this decision, which highlights a long-term feedstock shortage.

Two sources familiar with the matter confirmed that the decision on Wednesday was taken at a quarterly gathering of members of the China Smelters Purchase Team. The CSPT is a group of sixteen leading smelters who are expected to follow the guidelines in dealings for spot copper concentrate.

Treatment charges and refining costs (TC/RC), a major source of revenue for miners, are usually paid to refine concentrate and tend to decrease when the concentrate supply is tightening. They rise with an increase in ore availability.

The group has not provided such guidance for the second and third quarters, as spot prices have been negative since December. This means that smelters must pay miners.

One of the sources said that there was some discussion about the direction, but they ultimately decided to not set any guidance. It's best to wait until November, when the annual negotiations begin.

All sources asked for anonymity because they were not authorized to speak with media.

Global mining output is growing faster than smelting capacities, resulting in a tightening of concentrate supplies that squeezes smelters’ margins.

The suspension of Freeport’s flagship Grasberg copper mine in Indonesia, which is the second largest mine in the world, has further reduced the prospect of mined supplies.

The Chinese smelters have not reduced their output in a significant way, as the revenue generated from other products such as sulfuric acid, gold and silver, has offset the losses caused by copper sales. This year's copper production is expected to reach a new record.

Some overseas smelters have either reduced output or suspended operations because of a shortage of feedstock.

Chinese smelters have agreed to process concentrates from Chilean miner Antofagasta at no cost, which is a record for the industry. Reporting by Amy Lv in Beijing and Lewis Jackson in London, with editing by Jacqueline Wong & Michael Perry.
