# PHA bioplastics: Regulation

Safe to handle, but beware the biodegradable label

Source page: https://www.materialinsights.org/chemicals/pha/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 | none | Low hazard. Main risk is misleading biodegradability claims. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | Single-Use Plastics Directive 2019/904 (PHA counted as plastic); EN 13432; TUV OK compost HOME and OK biodegradable MARINE labels | PHA items are not exempt from single-use rules, removing part of their advantage. |
| **US** | ASTM D6400, D6691 (marine); state compostable labelling laws | Enables compostable and marine claims. |
| **Global** | ISO 17088 and ASTM standards for biodegradation | Certification basis. |

#### India

| Rule | Effect |
|---|---|
| **Plastic Waste Management (Amendment) Rules 2021 and 2024 on compostable and biodegradable plastics (CPCB certification, indicative)** | Compostable items permitted where single-use plastic is banned; biodegradable claims need certification |

#### Trade measures

- None found in sources reached

#### Supply risk

Very few producers and financially fragile; buyers face real counterparty risk, as Danimer's customers found in 2025.
