China's Epichlorohydrin Hits Record Profit Margins Amid Tightening Capacity

The market price for epichlorohydrin in China has recently been recorded at approximately RMB 11,000 per tonne, maintaining a level consistently above RMB 10,000 for the past six months and delivering substantial profit margins for producers. Preliminary calculations indicate that the theoretical annual profit margin for China's epichlorohydrin market surpassed 41% from January to November 2025, establishing it as one of the few bulk chemical products sustaining high profitability.

An analysis spanning the past 17 years reveals that China's epichlorohydrin sector has remained profitable for the vast majority of this period. The peak profitability was recorded in 2022, reaching 47%. With the exception of a minor loss in 2009, the market has consistently been in profit. Between 2009 and 2025, the theoretical profit margin for epichlorohydrin averaged around 23%, outperforming many other bulk chemicals and cementing its status as a relatively high-performing product.

A price peak of RMB 12,200 per tonne was observed in September-October 2025. Calculated at a price of RMB 12,000 per tonne, the theoretical profit margin would reach 49%, setting a new historical record.

Related products within the epichlorohydrin value chain - namely epichlorohydrin itself, propylene, liquid chlorine, and epoxy resin - have generally shown synchronised price movements in recent years, although their individual peaks and troughs have occurred at slightly different times.

Examining price fluctuations from 2009 to 2025, epichlorohydrin has demonstrated significant volatility. Its market peak occurred around 2018, reaching RMB 15,000 per tonne, while its trough was around 2016, dipping to RMB 7,300 per tonne. Within the same industrial chain, the historical peak for propylene occurred around 2011, reaching a maximum of RMB 11,000 per tonne, while its trough was also observed around 2016, falling to RMB 6,200 per tonne.

Analysts point to several factors behind the record-high profits in the epichlorohydrin sector:

Firstly, a significant reduction of outdated production capacity has occurred. According to incomplete statistics, China has retired more than 350,000 tonnes of chlorohydrin-based epichlorohydrin capacity over the past two years, accounting for approximately 15% of the current total production capacity. This makes epichlorohydrin one of the few chemical sectors in China where such consistent capacity elimination has taken place, providing firm support for market prices.

Secondly, China's liquid chlorine market is projected to remain in negative price territory through 2025. While driven by multiple factors, this situation undeniably benefits cost control for epichlorohydrin producers. Business Monitor statistics indicate the average liquid chlorine market price for 2025 will be RMB -112 per tonne, reaching as low as RMB -350 per tonne in July 2025. Given that producing one tonne of epichlorohydrin requires approximately 2.1 tonnes of liquid chlorine, this raw material provides a significant cost advantage.

Thirdly, the continuous expansion of wind power installations provides substantial demand support for downstream epoxy resin. Data from the National Energy Administration indicates China's wind power capacity reached 520.68 Gigawatts (GW) in 2024 and is projected to hit 625 GW in 2025 - a new historical peak. As a critical material for wind turbine blades, epoxy resin is extensively used in components including main spars, webs, and nacelle covers. Rough estimates indicate that each GW of wind power capacity consumes approximately 500 tonnes of epichlorohydrin, meaning the sector's rapid growth underpins demand.

Fourthly, the propylene-based production method yields epichlorohydrin at a cost approximately 15% lower than the glycerol-based process. The sustained decline in propylene prices has further enhanced this cost advantage, simultaneously suppressing the market competitiveness of the glycerol method and providing additional support for epichlorohydrin pricing.

Fifthly, policy guidance is shaping the industry. The National Development and Reform Commission's Industrial Structure Adjustment Guidance Catalogue (2024 Edition) classifies chlorohydrin-based epichlorohydrin production as a restricted development industry. It mandates the phasing out of non-compliant facilities by the end of 2025, specifically those exceeding water consumption and waste residue thresholds. Incomplete statistics suggest over 350,000 tonnes of capacity, predominantly chlorohydrin-based, may be subject to phase-out, a move expected to facilitate healthier industry growth.

However, the industry also faces certain developmental challenges:

Firstly, future planned and under-construction projects exceed 1 million tonnes in capacity. Total national production capacity is projected to surpass 3.2 million tonnes. While older facilities are being retired, these new projects will significantly expand industry scale, creating potential supply pressures.

Secondly, traditional chlorohydrin process plants that remain operational generate 40-50 tonnes of wastewater per tonne of product, causing severe equipment corrosion. This imposes significant environmental compliance pressures and high equipment maintenance costs on relevant enterprises.

Thirdly, propylene constitutes approximately 74% of epichlorohydrin's production cost. Recent pressures on propylene prices from increased coal-to-olefins supply, falling crude oil prices, and sluggish polypropylene consumption have provided a cost advantage for epichlorohydrin. However, a potential rebound in propylene prices, possibly led by a new cycle in the chemical industry's basic raw materials, could impact future epichlorohydrin profit margins.

Analysts suggest China's epichlorohydrin sector is poised for profound transformation: the phase-out of chlorohydrin-based capacity will accelerate, glycerol-based methods will dominate new installations, and green processes like bio-based and hydrogen peroxide methods will advance rapidly. The industry will upgrade towards integration and larger-scale operations. Furthermore, new capacity additions are expected to intensify competition, raw material price volatility will persist, and profit margins are forecast to narrow gradually. Enterprises possessing high-end product portfolios and integrated supply chain advantages are likely to maintain relatively stable profitability.
