# Propylene: Regulation

Ample supply, but a US-China propane trade risk

Source page: https://www.materialinsights.org/chemicals/propylene/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 |
|---|---|---|
| Flammable gas cat 1; gas under pressure | UN1077 | Highly flammable; heavier than air so leaks pool at ground level. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH; Seveso III; EU ETS (cracker benchmark) | Carbon cost on cracker-based supply. |
| **US** | OSHA PSM; EPA RMP | Process safety rules for large inventories. |
| **China** | Tariffs on US propane (34% to 125% in April 2025, 10% from 14 May 2025) | Reshaped PDH feed sourcing (S&P Global). |

#### India

| Rule | Effect |
|---|---|
| **MSIHC Rules 1989** | Propylene listed as a hazardous chemical; safety reports for major sites. |
| **PESO SMPV(U) Rules 2016** | Licensing for pressurised storage and transport. |
| **BIS Quality Control Orders on polymers** | PE QCO rescinded Nov 2025 (CareEdge); check BIS for PP status. |

#### Trade measures

- China tariffs on US propane (10% since May 2025)
- 2026 Hormuz disruption affecting Gulf propane and PP

#### Supply risk

Overall supply is ample. Feed risk sits in propane trade between the US, Gulf and China. Not on any critical raw material list.
