On October 21st, the Hebei Zhengyuan ammonia unit operated normally. The manufacturer's price today has been reduced by 20 yuan to 2190 yuan/ton, with some of the product being sold externally and primarily used at home, achieving an average daily sales volume of 300 tons. With a total capacity of 600,000 tons (approximately 1644 tons per day) and daily sales of 300 tons, the capacity utilization rate is relatively low, suggesting that there is an oversupply in the spot market, which may lead to increased downward pressure on prices. However, the reduction in price is modest (about 0.9%), which is considered a general bearish factor.
