Fluctuation of Calcined Coke Price in the International Market in Early 2025 and the Quality of Tanlin Carbon Electrode Paste

In early 2025, the price of calcined coke in the international market has shown significant fluctuations. This has attracted widespread attention from the industry, as calcined coke is a crucial raw material for Tanlin Carbon’s electrode paste production.

Price Fluctuation of Calcined Coke

According to relevant data, in February 2025, the price of calcined coke in Northeast Asia increased by 9.4% to $0.35/kg$, while the price in Europe decreased by 3.2% to $0.3/kg$. The prices in North America and the Middle East remained unchanged at $0.24/kg$ and $0.15/kg$ respectively. In the Chinese market, affected by the sharp rise in the price of low – sulfur petroleum coke, the price of calcined coke has also shown a significant upward trend. For example, in the first ten days of February, the price of ordinary – quality low – sulfur calcined coke in the market increased by 2400 yuan/ton compared with the beginning of the year, with an increase of 34.29%.

Factors Influencing Price Fluctuations

The main factor influencing the price of calcined coke is the supply and demand relationship. On the supply side, the output of petroleum coke, the raw material of calcined coke, is affected by factors such as the operating rate of refineries and the quality of crude oil. On the demand side, the downstream industries of calcined coke, such as the electrolytic aluminum and negative electrode material industries, have a great impact on its demand. For example, the electrolytic aluminum industry is expected to perform strongly in 2025, and the start – up of aluminum plants is expected to continue to rise, which will increase the demand for calcined coke. In addition, the development of the emerging negative electrode material industry has also become a supporting factor for the price of calcined coke.
