On August 21, the synthetic ammonia market in Southwest China continued to be weak. The reference for mainstream factories in Sichuan and Chongqing was 2,580 - 2,700 yuan/ton, and the price of ammonia collected in Guizhou was around 2850 yuan/ton. In the short term, the market is not good enough, prices are operating under pressure, and we will wait and see the trend of surrounding markets.
