Recently, the price of domestic fluorine chemical related products has risen sharply. At present, the average domestic price of domestic fluorite powder enterprises is close to 2,850 yuan/ton, which is about 7% higher than the price before eleven, and the price has increased by more than 10% since the beginning of September. The average price of hydrofluoric acid exceeded 12,000 yuan / ton, up nearly 20% from the previous month. At the same time, the average price of refrigerant R22 exceeded 22,000 yuan / ton, up 7% from the previous month, and the price rose more than 40% from the beginning of this year. .

The northern fluorite mines have been discontinued and limited production has affected supply. After the 11th holiday, the temperature in the north gradually declined. The fluorite plant in Inner Mongolia and Hebei began to stop in November due to low temperature. At the same time, due to the continuous growth of downstream air conditioner output this year, the current industry inventory is at a low level. The suspension of production by some manufacturers has made domestic supply tight. In the long run, fluorite is listed as a “strategic resource” in China. The reserve-production ratio is much lower than the international average. In order to achieve sustainable development, the state has frequent policies to restrict the expansion of fluorite capacity through strict access standards. Since 2017, environmental protection measures have continued to escalate, frequent inspections have reduced the operating rate of enterprises, and unqualified enterprises have been forced to shut down to further control fluorite production capacity.

The strong price of sulfur supports the rise in the price of hydrofluoric acid. Recently, domestic sulfur prices have continued to rise. At present, some domestic manufacturers are offering close to RMB 1,400/ton, which is more than 18% higher than the price in early September. Therefore, the price of sulfuric acid has continued to rise in the near future. Since the consumption of sulfuric acid in the production of hydrofluoric acid per ton is about 3 tons, the price of hydrofluoric acid has recently risen sharply under the cost of fluorite and sulfuric acid. In the long run, anhydrous hydrofluoric acid is a dangerous chemical. Therefore, it is under the strict control of policies and regulations in production, storage and transportation. In recent years, China has continued to strengthen its work on the import and production management of hydrofluoric acid industry. The capacity of anhydrous hydrofluoric acid is still in a contraction trend.

Production quotas have shrunk and R22 prices have continued to rise. Recently, the price of the second-generation refrigerant R22 has continued to rise, and the current domestic bulk supply is very tight. According to Zhuo Chuang Information, the quotas for domestic refrigerant manufacturers in September-December have been less than 20%. At the same time, domestic air-conditioning enterprises will start a new cold-year production cycle in November, and the situation of tight supply will be further intensified before the end of the year. In the long run, China, as a Party to Article 5 of the Montreal Protocol (ie developing countries), has officially implemented quota management for R22 since 2013. By 2015, China's HCFCs production will be in the baseline year (2009-2010). The average level will be reduced by 10%; by 2020, China's HCFCs will be eliminated by 35%, and in 2025, it will be eliminated by 67.5%, and will be completely eliminated by 2030. Domestic R22 production quotas in 2018 have dropped from 434,000 tons in 2013 to 274,000 tons, and domestic production quotas will drop to 200,000 tons by 2020. At present, China's HCFC-22 production capacity is about 600,000 tons, considering that the room air conditioner R22 use quota is 47,000 tons, the downstream PTEF capacity is about 110,000 tons, and the monomer and TFE route R125 capacity is 106,000 tons, the overall demand for R22. At around 426,000 tons. The new R125 capacity and PTEF capacity in the future will further boost the demand for R22 as raw materials, resulting in a tight supply of R22. At the same time, R22 is used as an intermediate for other refrigerants. The tight supply also checks the supply of other refrigerants, resulting in tight supply of refrigerant.
