Heilong Agricultural Chemical Co., Ltd. is a large-scale enterprise with pesticide-based products. A few years ago, with the assistance of the China Chemical Planning Institute, they conducted a survey and screening and planned 17 construction projects with a total investment of approximately RMB 480 million. However, due to shortage of funds, these projects have been set aside for nearly five years.
The Black Dragon Agrochemical Company had used various forms of investment promotion and had contact with 21 large and small companies at home and abroad. However, it was not until July 2004 that the assets were reorganized with China National Chemical Industry Group, which fundamentally solved the problem. Shortly after joining the China Chemical Industry Group, Heilong Agricultural Chemical Co., Ltd. received 10 million yuan of funds for technological upgrading of caustic soda production, 2.4D-acid, and an annual increase of 500 tons of dimethyl tetrachloric acid. Currently, these projects are new. Increase sales revenue by more than 10 million yuan. Heilong Agricultural Chemical Co., Ltd. plans to invest 120 million yuan in the next three years, focusing on six projects such as phosgene series. Among them, an annual output of 300 tons of refined fluazifop-Pyrogen is a good project that has been planned and demonstrated before it is reorganized.
At present, with the help of China National Chemical Industry Group, a number of construction projects are progressing smoothly. In the country's leading position in the annual output of 300 tons of oxalone original drug project. The smooth implementation of the loan guarantee provided by China National Chemical Industry Group is expected to be completed before the end of this year. The strategic cooperation partner agreement established by Heilong Agricultural Chemical Co., Ltd. and a Dalian company for new product development and research projects has also made breakthrough progress. After the reorganization, Black Dragon Agrochemicals revived.
