The head of Japan Mining Industry Association JMIA said that Japanese copper smelters were negotiating treatment and refinement charges (TC/RCs), which will be implemented in 2026, with global miners. They are seeking to reach agreements at levels other than the benchmarks set by China, which should remain low.

The TC/RCs are the fees that miners pay to refine concentrates into metal. They are a major source of income for smelters. Charges tend to decrease when concentrate supplies are tight and increase when ore is more available.

China is leading the global smelting expansion, which has led to a shortage of concentrates. This has squeezed the margins of smelters.

According to two sources in the industry, for 2025 annual TC/RCs a Chilean mining company and a Chinese smelter have agreed to $21.25 per ton, and 2.125 cents a pound. Japanese smelters, on the other hand, secured better terms of $25 per ton, and 2.5 cents a pound.

Tetsuya Tanahka, Chairman of the JMIA said that Japanese smelters were trying to create a different market from the global benchmark for 2026 by signing contracts on an individual basis rather than following the benchmark.

He said: "It is unclear where the levels will be landed, but these moves are already underway."

He said that the positions of miners vary. Some insist on selling to the highest bidder, which is in line with economic principles. Others see risks when relying too heavily on one country.

Tanaka warned Japanese smelters that they would continue to be faced with tough conditions. A significant impact is expected on earnings next year, as "smelters" in certain regions are likely to negotiate at low TC/RC rates.

In October, Japan and Spain issued a rare statement together expressing their deep concern about the tumbling TC/RCs and warning that both miners and smelters cannot develop sustainably in current conditions.

Tanaka, the president of Mitsubishi Materials, announced on Wednesday that it will reduce its primary copper smelting production by 30 to 40 percent by 2035, as it moves to secondary smelting in order to increase profitability.

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. (Reporting and editing by Thomas Derpinghaus; Yuka Obayashi)
