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 |  |  |
| **World output** | not published |  |  |
| **Capacity utilisation** | not published | Songwon reports persistent oversupply and pricing pressure from Asia in 2025 and expects demanding conditions in 2026. | Songwon FY2025 results |
| **Concentration** | BASF, Clariant and Songwon named as leading stabiliser players (2017) | No market shares published in sources reviewed. BASF, Avient, Dow, Lanxess and Evonik named leaders across all plastic additives (BCC 2024). | MarketsandMarkets (2017); BCC Research (2024) |
| **New capacity** | not published | Chinese capacity additions underlie the oversupply cited by Songwon; no named projects retrieved. | Songwon FY2025 results |

#### Top producing countries
 Asia-Pacific (demand) 57% · $34.8 billion of $61.5 billion plastic additives demand (2024) North America (demand) 19% · $11.9 billion (2024)

#### Largest producers: India

| Company | Country | Volume | Year | Source |
|---|---|---|---|---|
| **Vinati Organics** Capacity not verified in sources reviewed. | India | not published | n/a |  |
| **Platinum Industries** Not verified. | India | not published | n/a |  |
| **Baerlocher India Additives** Not verified. | India | not published | n/a |  |
| **Clariant Chemicals (India)** Not verified. | India | not published | n/a |  |

India makes PVC stabilisers widely and has started antioxidant production (Vinati), but imports most high-performance antioxidants and light stabilisers from BASF, Songwon, Adeka and China. Growth in Indian polymer capacity (Reliance, IOCL, HMEL) raises demand.

#### Position by region

| Region | Position |
|---|---|
| **US** | Milliken and alkylphenol producers; US trade measures affect Asian suppliers (Songwon). |
| **EU** | BASF, Clariant, Baerlocher; high energy costs (Songwon). |
| **India** | Import-reliant for high-end stabilisers. |
| **China** | Growing exporter; source of price pressure. |
| **Japan** | Adeka. |
| **Middle East** | Polymer producers are big buyers. |
