As a small variety of yellow phosphorus, the market trend in the first half of the year is similar to that of previous years. It has always been a wave of trading patterns, and the price has been maintained at a narrow range of 14,000 to 15,000 yuan (ton price, the same below). On July 3, CCTV's "Focus Interview" exposed the phenomenon of yellow phosphorus production in some areas of Guizhou. The industry has serious exhaust gas exhaust and phosphorus and phosphorus mud pollution. Affected by this news, Guizhou Huang Phosphorus enterprises have all ceased production and rectification. The yellow phosphorus plants in Yunnan and Sichuan have been “stopped”, resulting in a sharp drop in the overall operating rate of the industry. The market supply has dropped sharply, coupled with insufficient downstream inventory, and product prices have soared. However, the industry believes that there is no positive change in the demand side, and the price surge caused by external factors will not last too long. With the elimination of short-term interference factors and the resumption of production shutdown, the yellow phosphorus market will return to silence.
