October 28th News
According to the Spotcom AI assistant, as of October 27, 2026, the spot market for petroleum coke in China showed a clear divergence in prices among different categories. High-sulfur coke prices were adjusted downward, while low-sulfur coke remained relatively firm, with the overall average spot price slightly increasing.

However, the price is currently in a high range within the past year's cycle, and the room for further increases is relatively limited. Market participants should closely monitor the fluctuations in upstream crude oil prices and the pace of rigid demand purchases in downstream sectors such as steel and graphite electrodes.
