In 2020, under the influence of the "black swan" of the coronavirus, all industries including the glass industry have suffered considerable impact.

Due to the severe impact of the coronavirus, the average inventory level of float white glass from January to March exceeded 50 days, and the price quickly fell from a high of 1,800 yuan/ton to a historical low of 1,200-1300 yuan/ton. All float glass companies are generally at a loss. Especially in March-April, the market price of original glass sheets fell all the way, and even fell to the lowest price of 53 yuan/heavy container in central China in five years. Because the demand side is difficult to influence and play a role, under the coordination of the association, the float glass company jointly reduced production by 30% in order to stabilize the market price.

When the industry was in a downturn, a company in Shandong took the lead in raising the price. The price at that time was a high ex-factory price of 64 yuan/heavy container. At the beginning, the industry did not think that this wave of price increases was a hype. However, the price increase has been going on for more than a few months! Companies focusing on high-end glass have increased from the lowest ex-factory price to about 1,800 yuan/ton. As of May 14, 2020, a company’s single-day price increase was 120 yuan/ton, the highest single-day price increase in ten years.

It can be said to be "rise"! Professor Niu Xiao believes: This is not a rise! Is returning to normal and reasonable prices!
