# Acrylics (PMMA): Regulation

Cyanide plants and runaway monomer risks

Source page: https://www.materialinsights.org/chemicals/pmma/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 |
|---|---|---|
| PMMA not classified; MMA flammable liquid category 2, skin sensitiser, STOT SE 3 | UN1247 (MMA monomer) | Runaway polymerisation of MMA in storage; HCN in the ACH route is acutely toxic. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH registration of MMA; Seveso III for HCN sites; food-contact Regulation 10/2011 | Major-hazard controls on ACH plants |
| **EU** | Medical Device Regulation for bone cement and lenses | Strict quality control for medical grades |
| **US** | OSHA PSM and EPA RMP for HCN | Safety management at ACH sites |

#### India

| Rule | Effect |
|---|---|
| **MSIHC Rules 1989 (HCN, MMA)** | Hazardous chemical controls for importers and users |
| **Plastic Waste Management Rules (EPR)** | Limited impact on durable PMMA |

#### Trade measures

- No major MMA or PMMA trade remedy found in sources reached

#### Supply risk

Low to moderate: global overcapacity, with China at 44%. India depends on imports but from many suppliers.
