China Petrochemicals Market Trends

China’s petrochemical sector is presently defined by aggressive capacity expansion, especially in olefins. In 2023, China contributed about 60 % of global capacity growth, primarily in ethylene and propylene, pushing global utilization rates below 82 %. Ethylene capacity exceeding local demand stood at –1.6 million t in 2024, but is projected to rise by 6.3 million t in 2025, totaling +11.5 million t surplus. Similarly, propylene’s surplus grew from +2.7 million t in 2024 to a forecast +20.3 million t in 2025, representing one of the largest annual capacity jumps. Despite this build-out, operating rates are constrained. Through the downturn since mid‑2023, utilization hovered in the high‑70 % range, with goals to rebound into the mid‑80 % bracket as operators optimize plants and increase runs. Meanwhile, domestic feedstock demand for naphtha, LPG, and ethane rose by approximately 1.7 million barrels per day (mb/d) in 2023 relative to 2019 levels—underscoring the petrochemical sector as a leading consumer segment of crude oil. Trade tensions are also shaping dynamics. In 2024, China imported 62 % of its 1.4 mb/d LPG and ethane from the U.S., and accounted for nearly all U.S. ethane exports; recent tariffs of 34 % threaten to disrupt this supply linkage.

To mitigate supply risk, Chinese firms are investing heavily in ethane crackers, mid‑stream storage, and Very Large Ethane Carriers—spending over USD 16 billion, with 2025 imports forecast between 6.3–8.2 million t. Downstream, China’s crude processing reached a record 14.8 million b/d in 2023, enabling greater petrochem feedstock and integration. However, economic and property-sector weakness in early 2024 led to imports falling by 3.1 % and exports contracting by 1.7 %, which dampened demand for packaging, electronics, and construction-grade polymers. Together, these trends point to a market in transition: record-capacity build-out, oil-linked feedstock surging, and optimizing operations amid shifting domestic demand and geopolitical headwinds. Oversupply is rising: in 2023, global excess capacity for six main building blocks surged to 218 million t, nearly triple the 2000–2022 average of 76 million t. China remains the epicenter, with 2024/2025 olefins expansions outweighing many regional markets combined.

China Petrochemicals Market Dynamics

DRIVER

Rising integration of refinery and petrochemical complexes

In China, over 60% of new capacity between 2020 and 2024 was built through integrated refining and petrochemical complexes. These integrated plants optimize feedstock utilization, lower costs, and increase overall output flexibility. For instance, Zhejiang Petrochemical’s facility in Zhoushan has a crude processing capacity of 20 million tonnes/year and an ethylene production capacity of 4.2 million tonnes/year, with further expansion expected. Hengli Petrochemical’s Dalian complex processes 20 million tonnes/year of crude and yields 1.5 million tonnes/year of ethylene. This model allows producers to shift between fuels and chemicals based on market demands and pricing, giving them competitive agility. The output from these integrated setups has enabled China to meet over 80% of its polymer demand domestically in 2024.

RESTRAINT

Overcapacity and declining utilization rates

One of the key restraints is the growing surplus in olefins and aromatics capacity. Ethylene capacity exceeded local demand by 1.6 million tonnes in 2024 and is forecast to reach a surplus of 11.5 million tonnes by 2025. Similarly, propylene’s overcapacity will expand from 2.7 million tonnes in 2024 to 20.3 million tonnes by 2025. This excess capacity has resulted in ethylene plant operating rates falling below 80%, compared to 88–90% in the early 2010s. Such underutilization raises the unit cost of production and makes it harder for local players to remain profitable in a globally competitive pricing environment. Additionally, export margins are shrinking, as global demand growth slows and supply chain disruptions persist.

OPPORTUNITY

Expansion of downstream specialty chemicals and new material applications

As China shifts towards high-tech manufacturing, demand for specialty petrochemicals—used in semiconductors, EVs, 5G infrastructure, and photovoltaics—is rising. In 2024, the Chinese specialty chemical market surpassed 60 million tonnes, up from 52 million tonnes in 2021. Companies like Wanhua Chemical and Sinochem are investing in high-performance polyurethanes, advanced plastics, and silicone derivatives. China’s “Made in China 2025” initiative has designated key sectors like aerospace, electronics, and green energy for localized chemical innovation. New material investments are set to reach RMB 800 billion by 2026, boosting demand for high-purity solvents, engineering polymers, and flame-retardant additives—all derived from petrochemical feedstocks.

CHALLENGE

Geopolitical tensions and feedstock supply risk

China’s reliance on foreign LPG, ethane, and naphtha feedstock poses a major vulnerability. As of 2023, 62% of China’s 1.4 million barrels/day of LPG and ethane imports came from the United States. However, a 34% tariff imposed on U.S. ethane in 2024 threatens this crucial trade flow. This challenge has prompted significant investment in domestic ethane storage and transportation, including the construction of Very Large Ethane Carriers (VLECs) and multiple ethane terminals. Despite this, the cost of rerouting or switching suppliers could raise feedstock costs by 20–30%. Additionally, trade barriers restrict access to Western technologies used in high-efficiency catalyst systems, automation tools, and environmental compliance equipment, limiting modernization potential.
