At present, China's coking industry is facing widespread operational challenges and is experiencing losses across the entire sector. The domestic price of coke has dropped to 950 yuan per ton, while the average export price has fallen to 130 U.S. dollars per ton—a 50% decline. This sharp drop has led to a significant backlog of products, as overcapacity continues to plague the market. Meanwhile, the cost of raw coal has been rising, further squeezing profit margins. As a result, coke has become one of the few industries identified by the National Development and Reform Commission as being in surplus. During a recent coke market symposium in 2005, industry experts called for stronger macroeconomic control over the coking sector, emphasizing the need to accelerate restructuring, eliminate outdated production capacity, and promote industrial upgrading. Since 2002, rapid economic growth and the expansion of the steel industry have driven a surge in investments in the coking sector. At that time, China had not yet introduced an access system for the coking industry, allowing many small-scale coke ovens that did not meet national industrial policies to operate unchecked. This led to a dramatic increase in domestic coke production capacity. According to official data, in 2002, China’s total annual capacity for machine-made coke was 108 million tons. By the end of 2005, this had more than doubled to approximately 320 million tons—almost tripling in just three years. Additionally, there were ongoing projects with an annual capacity of 100 to 150 million tons. These figures far exceed the actual market demand, which stands at around 270 million tons per year. Currently, China’s total coking capacity is spread across more than 1,300 enterprises, with an average production of less than 200,000 tons per company. In addition, there are tens of millions of tons of unregulated "soil coke" (unlicensed or illegal coke production) still in operation. These facilities are not only inefficient but also contribute to severe environmental pollution and poor resource utilization. They do not align with national coking industry policies and pose a serious challenge to sustainable development in the sector. (Yao Wen)
