Epoxy resins: Production
Why half the world's epoxy plants sit idle
Why half the world's epoxy plants sit idle What this tab covers Who makes it and how much: world capacity and output, utilisation, the top producing countries and companies globally and in India, concentration, new capacity coming, and each region's position.| Measure | Figure | Detail | Source |
|---|---|---|---|
| World capacity | about 6.5 Mt/yr (2023); China about 3.4 Mt/yr (2023, up 13%), expected above 3.7 Mt/yr | PRChem via GII, 2025 | |
| World output | about 3.27 Mt (2023) | PRChem via GII, 2025 | |
| Capacity utilisation | about 50% (2023, derived) | 3.27 Mt output over 6.5 Mt capacity. Chinese plants commissioned in 2023-2024 met weak demand; some starts were delayed by poor margins (SCI99). | PRChem via GII; SCI99 2024-2025 annual report summary |
| Concentration | China about 52% of capacity; Asia-Pacific over 5 Mt/yr, about 77% (2023, derived) | Top-5 company share not published. Large Chinese makers include Jiangsu Sanmu and Shandong Bluestar Dongda (named in US cases). | PRChem via GII; US ITA 2025 |
| New capacity | about 0.5 Mt/yr named outside China, plus several Chinese projects | Aditya Birla +123 kt/yr (FY2025-26); DCM Shriram 75 kt/yr (2029); Chimcomplex Romania 50 kt (2025); Akkim Turkey 43 kt (2025); AO GC Titan Russia 40 kt (2028); Ruixiang China 95 kt (2024); Anhui Hengxing, Zhejiang Haobang and Dongying Hebang building plants (PRChem; Grasim). | PRChem via GII, 2025; Grasim Q3 FY2025 |

India has two main producers, Aditya Birla and Atul, and still imports enough for DGTR to impose five-year duties of $37-483/t on liquid epoxy from China, Korea, Saudi Arabia, Taiwan and Thailand in November 2025 (Indian Chemical News). India has no BPA plant, so all BPA is imported (BPA tile). National demand is not published in sources reached.
Position by region
