Formosa Petrochemical Corp., a Taiwan-based refiner and shipowner, has declared force majeure on portions of its petrochemical production and halted parts of its ethylene and propylene output. The company attributed the move to continued disruption of tanker deliveries of crude feedstock tied to the Middle East war.
Why it matters
The move signals how disruptions in the Strait of Hormuz can ripple into downstream petrochemical supply chains far from the Middle East. Formosa's shutdown could affect the availability of ethylene and propylene, key building blocks for plastics and other materials.
Formosa has not quantified the shutdown, so no capacity loss or duration figures are available. The company has only confirmed that portions of its ethylene and propylene output have been halted.
The players
Formosa Petrochemical Corp.
A Taiwan-based refiner and shipowner whose petrochemical operations feed into global plastics and chemical markets.
The details
A Formosa spokesperson said the force majeure notices were triggered by disruption in the Strait of Hormuz, which delayed tanker deliveries of crude feedstock. The company has not said how long operations will remain curtailed or when full output will resume.
Timeline
Force majeure declared with the article published on November 2, 2026; the core event date is not specified in the source.
Market Landscape
Formosa's curtailment shows how shipping bottlenecks in the Strait of Hormuz are reaching upstream feedstock supply and then downstream petrochemical output. The disruption places pressure on integrated producers that depend on steady crude deliveries to keep ethylene and propylene flowing.
Buyers of plastics made from polyethylene and polypropylene could face tighter supply and possible price pressure if the shutdown persists. Formosa's Point Comfort, TX complex produces LDPE, HDPE, and LLDPE, so U.S. resin users may also feel effects depending on how long operations are curtailed.
The takeaway
Supply shocks at chokepoints like the Strait of Hormuz can reach far beyond oil, disrupting the plastics and chemicals that depend on it. Watch for Formosa's updates on restart timing to gauge how long the disruption will last.
