# Purified terephthalic acid: Regulation

How an Indian quality order switched imports off and on

Source page: https://www.materialinsights.org/chemicals/pta/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 or eye irritation cat 2 under most notifications (indicative) | not regulated | Combustible dust; plants handle acetic acid, bromide and high-pressure oxidation. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH; EU Ecodesign and textile EPR proposals | Pressure for recycled polyester content (indicative) |

#### India

| Rule | Effect |
|---|---|
| **BIS quality-control order on PTA (stalled Chinese imports from mid-2023; revoked late 2025)** | Reopened Chinese supply to Indian yarn makers (S&P Global) |

#### Trade measures

- India's QCO revocation in late 2025 (S&P Global)
- US tariffs on Chinese goods weigh on polyester textile exports (Argus, 2025)

#### Supply risk

High concentration in China. India's import dependence makes its textile industry exposed to Chinese pricing and trade policy. Not on critical lists.
