In 2012, the overall performance of listed nitrogen fertilizer companies showed a significant upward trend. This was driven by lower sales costs, higher selling prices, strong domestic demand in the first half of the year, and a robust export performance in the second half. Additionally, the ample supply of natural gas helped improve profitability. Meanwhile, listed compound fertilizer companies continued to innovate, introducing new products and enhancing their agricultural services, which contributed to a notable increase in profits. However, the industry also faced challenges, such as overcapacity, which led to prolonged low prices for phosphate and compound fertilizers. As a result, phosphorus-based chemical companies either maintained flat performance or even suffered losses.
According to an analysis of the annual reports of 25 listed fertilizer companies in 2012, several nitrogen fertilizer firms saw impressive growth. For example, Cangzhou Dahua, Hualu Hengsheng, Jianfeng Chemical, and Xinlianxin reported net profit increases of 310.88%, 27.31%, 33.53%, and 72.4% respectively. Xinlianxin Fertilizer Co., Ltd. achieved a net profit of 311 million yuan, a 72.4% year-on-year increase, marking a new high since its listing. The company attributed this growth to reduced average cost of sales for urea and methanol, as well as higher selling prices.
Despite the overall positive trend, some nitrogen fertilizer companies experienced declines. Huachang Chemical and Liaotong Chemical, for instance, saw sharp drops in net profit—199.77% and 97.67% year-on-year. However, their fertilizer segments still showed improvement compared to the previous year. Unfortunately, these gains were not enough to offset the losses from other petrochemical operations within the companies.
In contrast, phosphorus chemical companies struggled with overcapacity and high production costs, leading to consistently low prices for phosphate and compound fertilizers throughout the year. This resulted in flat or negative performance for many firms. Yuntianhua, for example, reported operating revenue of 9.893 billion yuan but suffered a total loss of 5.17 billion yuan and a net loss of 548 million yuan. The company's performance was further affected by increased downtime at its ammonia and urea plants.
On the other hand, compound fertilizer companies like Kim Jung-dol and Xindu Chemical demonstrated strong profitability. Kim Jung-dol’s net profit attributable to shareholders reached 550 million yuan, up 25.31% year-on-year. Other companies also saw substantial improvements, with net profit growth ranging from 41.05% to 5.40%. These gains were largely due to the introduction of innovative products such as slow-release, nitro-compound, and water-soluble fertilizers, along with enhanced agrochemical services. Xindu Chemical, while experiencing lower net profit due to ongoing construction projects, still managed to grow its operating income by 5.64% compared to the previous year.
Wedge Prism
Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.
Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.circle wedge,square wedge,irregular wedge...Every materials,sizes,wedges and coatings may be available by custom orders. Standard and broadband antireflection coatings are available upon request.
