Rongsheng Petrochemical (Rongsheng), established in 1995 and headquartered in Hangzhou, China, is a leading global petrochemical enterprise. In this year's Chemicals 50 report by Brand Finance, Rongsheng ranks as the only Chinese brand among the sector’s top five most valuable names globally.
The brand leverages the world's largest single-site refining and chemical integration project, Zhejiang Petroleum & Chemical Co., Ltd. (ZPC), which has a refining and chemical integration capacity of 40 million tonnes per year. This project enables Rongsheng to build a comprehensive industrial chain spanning from crude oil to downstream advanced materials.
As a benchmark for China's private petrochemical industry, Rongsheng demonstrates strong brand competitiveness through its focus on the research and development of high-end chemical materials, digital transformation, and green and low-carbon development.
Strategic alliances and global expansion as drivers of brand value growth
The growth of Rongsheng's brand value reflects its forward-looking approach to global strategic partnerships. From 2025 to early 2026, Rongsheng further deepened its cooperation with global energy giant, Saudi Aramco. At the end of 2024, the two parties signed a Framework Development Agreement aiming to jointly advance the expansion of the Saudi Aramco S-Oil Refinery (SASREF) project in Jubail. This strategic partnership supports the stability of raw material supply while strengthening Rongsheng’s position in the global market through technological collaboration and market synergies.
In 2026, Rongsheng's brand value grew by 2%, enabling it to retain its position among the world’s top five most valuable chemical brands. This achievement highlights Rongsheng's operational resilience in a complex environment and reflects its increasing influence across the global petrochemical value chain.
Technological innovation and digital transformation as drivers of core brand competitiveness
Technological innovation remains Rongsheng's strongest asset in retaining brand success. The brand consistently maintains high investments in R&D, focusing on clean energy, high-end materials, and environmentally sustainable processes. In February 2025, Shengyuan Chemical Fiber, a subsidiary of Rongsheng, was selected for Zhejiang Province's 'Smart Factory' certification list, reflecting authoritative acknowledgement of its Al-driven industrial and digital transformation efforts.
By deeply integrating Al technology across its operations, Rongsheng has achieved intelligent monitoring and dynamic optimisation throughout its entire production process, improving production efficiency and ensuring consistent product quality. This proactive adaptation of emerging technologies has reinforced Rongsheng’s leadership in specialised markets, including high-end polyester fibers.
Sustainable development and ESG governance: Reshaping a green brand image
Rongsheng is taking a leading role in addressing climate change within the industry. Its MSCI ESG rating improved from BBB to A, marking the company’s highest performance to date and one of the top ratings achieved by a Chinese chemicals brand. Rongsheng’s efforts in carbon emission reduction, water resource management, and corporate governance exceed the global industry average. By integrating sustainability initiatives into its brand strategy, Rongsheng has successfully built trust among stakeholders, reinforcing a green, low-carbon, and international brand image.
Looking ahead, Rongsheng will continue to enhance its brand through new, quality-driven initiatives. By expanding global partnerships, accelerating digital transformation, and upholding ESG commitments, Rongsheng is not only maintaining its brand presence but also advancing the global petrochemical industry towards higher quality and more sustainable development.
