PPC raises the 2026 Japan Copper Premium to a record $330/T

Pan Pacific Copper (PPC), Japan’s largest supplier, has offered to sell the metal to domestic customers for a record price of $330 per metric ton by 2026. This was revealed on Friday by a source within the company.

It reflects fundamentals of demand and supply. The physical delivery rate is three times higher than the benchmark LME price of $88, and is paid over and above LME benchmark prices. The rate also includes costs such as taxes and transport.

The source said that this year's rise is due to a steep fall in treatment and refining fees (TC/RCs), which are the fees miner pay to smelters for converting concentrate into refined metal. This has boosted the raw material acquisition costs, prompting a company to pass on the burden to its customers.

Concerns that the United States could impose tariffs on ingots of copper later this year has sparked speculative metal flows into North America. This has led to a tightening of supply in Asia.

Source declined to identify themselves due to the sensitive nature of the subject.

Mitsui Mining and Smelting, Marubeni and JX Advanced Metals own 47.8% of PPC. Mitsui Mining and Smelting holds 32.2% and Marubeni 20%.

As their global counterparts, Japanese copper smelters also face a tumbling TC/RC, shrinking margins for smelting due to a lack of concentrate supply, and growing smelting capacities in China.

Two?sources who are familiar with the situation said that Antofagasta, a Chilean copper miner, and a Chinese copper smelter reached an agreement last month to have zero TC/RCs by 2026.

In 2025, the lack of supply at mines such as Grasberg in Indonesia and Kamoa-Kakula, in the Democratic Republic of Congo, was so severe that spot processing fees became negative. Smelters were left paying for a source of revenue they normally rely on. (Reporting and editing by Clarence Fernandez; Yuka Obayashi)
