# Acrylonitrile: Regulation

Toxic, carcinogenic and releases cyanide when it burns

Source page: https://www.materialinsights.org/chemicals/acrylonitrile/regulation/

What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.

#### Hazards

| Classification | UN number | Key risks |
|---|---|---|
| Flam. Liq. 2; Acute Tox. 3 (oral, dermal, inhalation); Carc. 1B; Skin Irrit. 2; Eye Dam. 1; Skin Sens. 1; Aquatic Chronic 2 | UN1093 | Toxic and carcinogenic; can polymerise violently if uninhibited; fires release hydrogen cyanide. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH (restricted occupational exposure); Seveso III | strict workplace limits |
| **US** | OSHA ACN standard (2 ppm TWA); EPA HON rule (2024) | emissions controls at plants |

#### India

| Rule | Effect |
|---|---|
| **MSIHC Rules 1989 (ACN listed as hazardous chemical)** | storage and import licences |
| **DGTR ADD recommendation on NBR (25 Sep 2025)** | protects the downstream nitrile rubber chain (Apcotex) |

#### Trade measures

- India NBR ADD recommendation (Sep 2025)
- No ACN-specific duties identified in India

#### Supply risk

India has no domestic ACN, so its ABS, acrylic fibre and acrylamide chains rely on imports from North-East Asia. Global oversupply makes supply plentiful for now.
