China's Chemical Juggernaut: Global Producers Squeezed as Beijing Expands
China's massive chemical industry growth is driving down prices and forcing foreign plants, including US facilities, to shut down.
The global chemical landscape is undergoing a seismic shift as China chemical industry expansion reaches unprecedented levels, leaving foreign manufacturers struggling to survive. According to a recent report by the Rhodium Group, Beijing's aggressive push to dominate chemical manufacturing is not only erasing the market share of international firms within China but is also triggering a price war in global markets.
A Massive Surge in Production Capacity
The scale of China's growth is staggering. Over the last 25 years, the country's chemical output has expanded 18-fold. Today, China controls more than 45 per cent of the global production capacity for plastic resins and basic chemicals.
However, this rapid growth has come with a caveat: overproduction. The Rhodium Group notes that China has built capacity that far exceeds its own domestic demand. This imbalance has led to a ripple effect of economic challenges, including:
- Plummeting product prices.
- Massive accumulations of unsold inventory.
- Shrinking profit margins for the Chinese manufacturers themselves.
Foreign Producers Caught in a Double Bind
International chemical companies are currently fighting a war on two fronts. First, they are being systematically pushed out of the Chinese domestic market as Beijing successfully replaces imports with homegrown alternatives. Second, they are facing an onslaught of low-priced Chinese exports flooding their own home markets.
The report suggests that the loss of the Chinese market has actually been more damaging to foreign producers than the rise of Chinese exports in other regions.
The American Fallout: Plant Closures
The real-world consequences of this competition are already appearing in the United States. Westlake Corporation, based in Houston, recently announced the closure of four production units across Mississippi and Louisiana, resulting in the loss of approximately 295 jobs.
These facilities produced industrial materials and chemicals, including polyvinyl chloride (PVC), which is essential for construction and piping. In a filing with the US Securities and Exchange Commission (SEC), Westlake explicitly blamed "global overcapacity" and the surge of low-priced Asian exports for the decision. The company noted that high transportation and manufacturing costs made three of its North American units no longer cost-competitive globally.
Additionally, Westlake is exiting styrene production due to a bleak export outlook. While the company expects the restructuring to eventually boost annual operating earnings, the immediate cost of these closures is estimated at USD 415 million.
Beijing's Strategy Amidst a Property Crash
For two decades, Beijing has prioritized reducing its reliance on imported industrial materials. However, this strategy hit a major snag in 2021 when the Chinese property market began to crash. Since construction is a primary consumer of chemicals, demand plummeted just as new factories were coming online.
Despite this downturn, the Chinese government shows no sign of slowing down. A September 2025 industrial plan, issued by seven government agencies, sets an ambitious target: an average annual growth of over 5 per cent in the value added by the chemical and petrochemical industries for 2025 and 2026.
The Road Ahead: Specialized Chemicals and Trade Wars
The new government plan focuses on:
- Upgrading existing facilities.
- Developing advanced, high-end chemical products.
- Aggressively expanding into international markets.
- Limiting certain types of new production capacities.
The Rhodium Group warns that while these upgrades might make Chinese firms more efficient, they won't necessarily solve the problem of surplus capacity. More concerning for foreign firms is the shift toward "specialized chemicals"—a high-margin segment where international companies have traditionally held a competitive edge.
In response to these pressures, the US is turning toward trade protections. On October 20, the US Department of Commerce launched investigations into whether specific chemical compounds from China are being sold at unfairly low prices to undermine global competition.
