Many small Chinese plants make half the world's resin 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** | not published in sources reached; China output 3.45 Mt in 2024 (estimate) |  | Chyxx 2025 |
| **World output** | world about 6.5-7 Mt (indicative); China 3.232 Mt (2023, up 7.27%) and 3.451 Mt (2024e) |  | Chyxx 2025; world indicative |
| **Capacity utilisation** | not published | Chinese UPR plants are many and small; output rose in 2023-2024 on downstream demand and higher run rates (Chyxx). | Chyxx 2025 |
| **Concentration** | China about half of world output; Asia-Pacific 43.45% of 2025 revenue | The industry is fragmented: many Chinese producers and a few Western groups (INEOS Composites, Polynt, AOC, Scott Bader). Top-5 company share not published. | Mordor via GII 2026; Chyxx 2025; China share indicative |
| **New capacity** | not published | No large named UPR projects found. Growth comes from incremental batch reactors, mostly in China and India (indicative). | indicative |

India has many small and mid-sized UPR makers serving FRP pipes, tanks, panels and quartz stone, but no capacity or output figures were found. Phthalic and maleic anhydride are made locally, while styrene and propylene glycol are imported (styrene and PO tiles).

#### Position by region

| Region | Position |
|---|---|
| **US** | Mature market; large boat, bath and SMC industry. |
| **EU** | Styrene exposure limits and cobalt classification push low-styrene and cobalt-free systems (indicative). |
| **India** | Water pipes and tanks under Jal Jeevan Mission-type programmes, construction and quartz stone (indicative); styrene and PG imported. |
| **China** | About half of world UPR; sensitive to property and quartz stone exports (Chyxx). |
| **Japan** | Small mature market. |
| **Middle East** | Pipe and tank fabricators for desalination and oil and gas (indicative). |
