Rongsheng Petrochemical: Revenue reached 148.63 billion yuan in the first half of the year! The 76 billion yuan Jintang project is accelerating construction.
Rongsheng Petrochemical is an important producer of polyester, new energy materials, engineering plastics, and high value-added polyolefins in China and Asia. The company primarily operates the Zhejiang Petrochemical Refining and Chemical Integration Project, which has the capacity to process 40 million tons of crude oil, 8.8 million tons of paraxylene (PX), and 4.2 million tons of ethylene annually, with a globally leading integration rate in refining and chemical operations.
The financial data of Rongsheng Petrochemical for the first half of 2025 reflects the structural challenges faced by the traditional refining industry.Operating revenue was 148.63 billion yuan, a year-on-year decrease of 7.83%; net profit attributable to shareholders was 602 million yuan, a significant year-on-year decline of 29.82%, with a net profit margin of only 0.41%.This is reflected in the context of a downward shift in international oil prices and a trend toward a more balanced supply and demand for crude oil, revealing that a profit model relying solely on refining and chemical operations can no longer sustain high growth.
It is worth noting that Rongsheng Petrochemical's high value-added product segment performed well, offsetting some downward pressure: Revenue from chemical products (accounting for 40.87% of total revenue) increased by 5.46% year-on-year to 607.421 billion yuan. Polyester chemical fiber films (accounting for 7.48% of total revenue), benefited from a differentiated product layout, saw a year-on-year revenue surge of 31.53% to 111.255 billion yuan, reflecting the gradual effectiveness of the company's "reduce oil, increase chemicals" strategy.
Although data from the National Bureau of Statistics shows that the processing volume of crude oil in industries above designated size reached 361.61 million tons from January to June 2025, a year-on-year increase of 1.6%, the overall profitability of the industry has not improved accordingly. This indicates that the refining industry has entered a mature stage, and companies must seek new growth points through extending the industrial chain and upgrading their product structures. Among them,The total investment in the Rongsheng Petrochemical Jintang New Materials Project has increased from the initial 67 billion yuan to 76 billion yuan.This demonstrates the company’s firm commitment to the new materials sector. The core highlight of this project lies in its production capacity layout for high-end chemical materials, especially the construction of a 200,000-ton-per-year POE (polyolefin elastomer) facility.
In the first half of 2025, despite the impact of industry cycles and financial market fluctuations, which put short-term pressure on revenue and net profit attributable to the parent company, Rongsheng Petrochemical demonstrated resilience in its main business with the growth of net profit excluding non-recurring items and the outstanding performance of high value-added products. Leveraging the core advantages of Zhejiang Petrochemical's integrated refining and chemical operations, strategic collaboration with Saudi Aramco, and forward-looking layout in the new materials sector, the company's long-term growth logic is clear. In the future, as new materials projects come on stream, international expansion is implemented, and the green and digital transformation progresses, Rongsheng Petrochemical is expected to further consolidate its position as a global chemical leader, achieving dual improvements in scale and quality, and creating sustained returns for shareholders.
In the context of a sluggish recovery in overall demand in the petrochemical industry, private refining and chemical enterprises are under short-term performance pressure. They are navigating through the industry's downturn by deepening the integration of their industrial chains, intensifying research and innovation in high-end materials, and exploring overseas markets as tools to transcend the industry's downcycle.
