I. Why Anhui's Chemical Sector Deserves Separate Attention

Anhui's chemical industry defies easy labeling. The province simultaneously hosts a petrochemical corridor along the Yangtze River, a coal-chemical basin in northern Anhui, and a phosphate-resource belt in Tongling — three distinct structural logics overlaid on the same map. The provincial government has institutionalized this arrangement through four officially designated chemical bases: the Anqing Petrochemical Base, the Huainan New-Type Coal Chemical Base, the Dingyuan Salt Chemical Base, and the Huaibei New-Type Coal Chemical Synthetic Materials Base.

Anhui is also among the Chinese provinces undergoing the most visible structural adjustment in chemicals: large central-enterprise projects are landing, local state-owned firms are under financial stress, and listed companies are making deliberate moves toward new materials. Understanding these concurrent dynamics is essential to reading the sector accurately.

II. Geographic Clusters: Three Poles, Distinct Hinterlands

The Anqing Petrochemical Pole, in southwestern Anhui, is the province's largest petroleum refining and chemical base, anchored by Sinopec's Anqing Branch. In 2023, the company's refinery-to-chemicals restructuring project reached full operation, featuring the world's first commercial-scale 3-million-ton/year heavy oil catalytic cracking (RTC) unit and China's largest dry-gas-to-ethylbenzene unit at 400,000 tons/year. The Anqing High-Tech Zone is designated as one of the five major refining-and-chemical bases in the Yangtze River Economic Belt, targeting a 100-billion-yuan new-materials industrial park.

The Northern Anhui Coal-Chemical Pole is centered on Huaibei and Huainan. The Huaibei New-Type Coal Chemical Synthetic Materials Base covers a planned 20.4 square kilometers; by 2023 it had achieved industrial output of 20.9 billion yuan, with 57 resident enterprises including 33 above-scale companies, 2 large state-owned enterprises, 5 listed companies, and 5 foreign-invested enterprises. Huaihua Group (under Wanbei Coal-Electricity Group) is the region's oldest coal-chemical enterprise, specializing in concentrated nitric acid, ammonium nitrate, and urea. Its concentrated nitric acid production and sales have consistently ranked among the national top, holding more than 20% of the domestic market share.

The Tongling Phosphate-Chemical Pole is led by Tongling Chemical Industrial Group and Anhui Liuguo Chemical (SSE: 600470). Tongling Chemical, founded in 1991, exceeded 23 billion yuan in revenue in 2022, ranking among China's Top 500 manufacturers. Liuguo Chemical focuses on integrated phosphate fertilizer and phospho-chemical production; its 2023 annual revenue was 8.062 billion yuan (per annual report), with a planned fertilizer output of 2.52 million tons. Products include diammonium phosphate, monoammonium phosphate, compound fertilizer, refined phosphoric acid, and phosphate salts, making it one of East China's largest listed phospho-chemical companies.

III. Key Enterprises and Supply Chain Structure

Anhui's chemical supply chain has a relatively clear vertical structure.

Upstream resource inputs: crude oil (imported, transported via the Yangtze), coal (produced locally in northern Anhui), and phosphate rock (primarily sourced from Guizhou and Yunnan, with limited local deposits in Tongling). Anqing Petrochemical's RTC unit maximizes conversion of crude oil into light olefins and aromatics, opening a core "crude → olefins → new materials" pathway for downstream synthetic material producers.

Mid-stream chemicals: Huaihua Group dominates the nitric-acid-based products segment; Tongling's phospho-chemical cluster leads in phosphoric acid and compound fertilizers, covering most major categories of agricultural chemicals.

New-materials extension layer: Wanwei Hi-Tech Materials (SSE: 600063), headquartered in Chaohu, best represents this layer. The company operates four segments — chemicals, chemical fibers, building materials, and new materials — with core products in polyvinyl alcohol (PVA) and downstream PVB resin and PVB film. Annual capacity includes 20,000 tons of PVA fiber, 38,000 tons of PVB resin, and 22,000 tons of PVB film. The company is actively transitioning from calcium-carbide-acetylene-based PVA to ethylene-based PVA, and plans a roughly 10-billion-yuan ethylene-based functional PVA facility in Jiangsu province — one of the most explicit new-materials commitments by any Anhui chemical enterprise.

IV. Structural Dependencies Across the Value Chain

Anhui's chemical sector carries identifiable structural vulnerabilities. The petrochemical segment depends entirely on externally sourced crude oil and is sensitive to Yangtze River freight disruptions. High-quality phosphate rock is concentrated in Guizhou and Yunnan; Tongling's local ore grades are comparatively modest. The coal-chemical segment, while backed by northern Anhui's own coal production, faces constraints on extraction volume and coal quality.

On the demand side, Anhui chemicals serve three primary markets: the Yangtze River Delta's manufacturing sector (synthetic materials and fine chemicals feeding textiles, automotive, and electronics supply chains); the agricultural market (fertilizers remain the revenue backbone of Liuguo Chemical and peers); and the expanding new-energy materials market (electrolyte solvents, functional films, etc.). The room to move up the value chain is substantial, but the paths diverge, and the competitive landscape remains fragmented.

Sales teams supplying upstream materials to these manufacturers can use Tianxia Gongchang to filter factory directories and decision-maker contacts by region and chemical sub-category, enabling precise outreach to procurement leads across Anhui's chemical industry.

V. Transition Pressures: An Uneven Provincial Picture

Anhui's provincial authorities issued detailed measures for high-quality chemical park development in March 2024, targeting 50% coverage of "six-in-one integrated" parks by 2025 and full coverage by 2027, with an explicit push toward circular, green, and smart-park standards. Under China's dual-carbon framework, provincial policy has set hard deadlines for factory relocation into designated parks and for "one cluster, one strategy" environmental remediation.

The impact on different actors is uneven. Sinopec's Anqing unit has already completed a major structural shift through capital investment, with a clear new-materials trajectory. Liuguo Chemical's phosphate fertilizer business is exposed to commodity-cycle volatility, and a diversification path is still taking shape. Wanwei Hi-Tech's new-materials strategy is backed by real investment commitments, though the flagship project is being built in Jiangsu rather than Anhui — a telling signal about the relative attractiveness of on-shore conditions.

Whether Anhui can successfully graft a new-materials layer onto the three-pillar petrochemical, coal-chemical, and phosphate-chemical structure depends on the pace of park infrastructure improvements, supply-chain resilience, and the accumulation of differentiated technical capabilities in a nationally competitive market. The question remains open, but several critical milestones are landing between 2023 and 2025, making this a sector worth watching closely.
