At present, China's soda production capacity is 33.29 million tons, an increase of 0.36% over the end of 2020. In April, Tianjin Soda Industry and Hubei Shuanghuan soda plant were shut down for maintenance, Nanfang soda industry, Jiangxi Jinghao soda industry and Yanhu magnesium industry were reduced for maintenance, and Jinchang ammonia soda plant had not yet produced products. As of April 15, the weighted average operating load of domestic soda plants was reduced to 83.7%, slightly lower than that of the same period last year, and the market supply was sufficient.

In the near future, the downstream photovoltaic glass market is weakening, and the profit situation is not as good as that in the early stage, but the production line changes little, and the heavy alkali consumption is stable; the price of float glass market rises slightly, coupled with the recent natural gas price reduction, the profit situation of float glass manufacturers continues to improve, and Zhuo Chuang information statistics has calculated that the average inventory days of raw material heavy alkali of sample float glass manufacturers are about 45 days, some of which are appropriate Stock in the market. As of April 15, the overall inventory of soda manufacturers was 870000 tons (including some manufacturers' external warehouse and port inventory), of which the heavy alkali inventory was about 480000 tons (including some manufacturers' port and external warehouse inventory), slightly lower than that of last week. The downstream demand of light caustic soda is slightly weak, the resistance to high price soda is obvious, and the main purchase is just demand. The light caustic soda inventory of soda manufacturers has picked up compared with last week.

With the market price rising to a high level and the speculative demand decreasing, there is not much stock preparation action of futures traders and traders, and the light warehouse operation is the main. In this cycle, the ex warehouse quotation of heavy alkali is 1770-1850 yuan / ton (the low end is the early-stage source quotation), and the shipping quotation of light alkali in some early-stage stock trade is more flexible. Most soda manufacturers mainly keep their prices stable. It is reported that the export prices of northwest and central China are adjusted flexibly. At present, the average ex factory price of light soda is 1744.6 yuan / ton, while the price of heavy soda is 1900-2000 yuan / ton. In the near future, the market continued to fluctuate, which had a certain impact on the mentality of the industry. There was a strong wait-and-see atmosphere in the market. In the short term, the domestic soda ash spot market may be weak.

Delivery of goods in May may may form a certain supplement to the market supply. Hubei Shuanghuan and Jiangxi Jinghao are expected to reduce maintenance until the end of this month. In May, Shilian plans to stop for maintenance for 25 days. Huachang Chemical, Zhongyan hongsifang and some ammonia alkali plants have not yet determined the physical examination and repair plan for furniture. If the maintenance plan is gradually implemented, it may form a certain positive support for the market. The photovoltaic glass market is weakening in the near future, and the implementation of the follow-up ignition plan remains to be seen. From May to June, the planned ignition line of float glass is relatively concentrated, and the demand for heavy soda is expected to increase. In the long run, the domestic soda spot market is still optimistic.
