# Polybutadiene rubber: Regulation

Tyre labels and coming EU abrasion limits

Source page: https://www.materialinsights.org/chemicals/polybutadiene/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 |
|---|---|---|
| not classified as polymer; residual butadiene (carcinogen 1A) and hexane controlled | not regulated | Butadiene and solvent fire and explosion risk at plants; pyrophoric aluminium alkyl catalysts. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | Tyre Labelling Regulation (EU) 2020/740; Euro 7 tyre abrasion limits to follow | Favour Nd-BR for low rolling resistance and wear |
| **EU** | REACH; IED emission permits | Solvent and butadiene emission controls |
| **US** | EPA NESHAP for polymers and resins; OSHA butadiene standard | Plant controls |

#### India

| Rule | Effect |
|---|---|
| **Hazardous and Other Wastes Rules: waste tyre EPR (2022)** | Tyre recycling obligations |
| **MSIHC Rules 1989 (butadiene)** | Hazard controls at Reliance plants |

#### Trade measures

- No major BR trade remedy found in sources reached

#### Supply risk

Moderate. Many producers, but butadiene supply depends on naphtha cracking. Nd-BR depends on Chinese rare-earth supply for its catalyst (rare earths are on EU, US and Indian critical lists).
