Purified terephthalic acid: Regulation

How an Indian quality order switched imports off and on

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

ClassificationUN numberKey risks
Not classified or eye irritation cat 2 under most notifications (indicative)not regulatedCombustible dust; plants handle acetic acid, bromide and high-pressure oxidation.

Main rules

WhereRuleEffect
EUREACH; EU Ecodesign and textile EPR proposalsPressure for recycled polyester content (indicative)

India

RuleEffect
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.
