In 2018, due to the decline in the export volume of citric acid, the major manufacturers of citric acid had a vicious competition. From the beginning of the price of 5000 yuan/ton all the way down, at the end of the lowest 3800 yuan/ton, the country's manufacturers without profit or loss operation. Citric acid rebounded strongly after February 2019 and should return to a reasonable level in my estimation. There is still room for a rebound.
