Formosa Petrochemical, a Taiwan-based refiner and shipowner, has declared force majeure on portions of its petrochemical production after tanker delays through the Strait of Hormuz disrupted crude feedstock deliveries. The company has halted parts of its ethylene and propylene output, and operators dependent on those feedstocks should expect supply uncertainty.
Why it matters
The disruption traces to the ongoing Middle East war, which has delayed tanker deliveries of crude feedstock moving through the Strait of Hormuz. Because force majeure lets a producer suspend contractual obligations when outside events prevent performance, buyers of affected petrochemical products may face delayed or reduced shipments.
Formosa has not released volume, capacity, or duration figures for the halted ethylene and propylene output, so the scale of the disruption cannot yet be measured against prior production. The affected Point Comfort, Texas complex produces LDPE, HDPE, and LLDPE, but no shares or tonnage were reported.
The players
Formosa Petrochemical Corp.
A Taiwan-based refiner and shipowner whose petrochemical operations supply ethylene and propylene to downstream plastics markets.
Formosa Plastics USA
The U.S. subsidiary operating an integrated petrochemical complex at Point Comfort, Texas, producing polyethylene resins.
The details
Formosa Petrochemical's force majeure notice covers portions of its petrochemical production, which depends on crude feedstock moving by tanker. When those tankers are delayed in the Strait of Hormuz, the refinery loses the raw input it needs to keep ethylene and propylene units running. A company spokesperson attributed the force majeure notices to the Strait of Hormuz disruption. The company's U.S. arm, Formosa Plastics USA, runs an integrated complex at Point Comfort, Texas that produces LDPE, HDPE, and LLDPE polyethylene resins, though no link between that complex and the halted output was specified in the source.

Market Landscape
The disruption sits within a broader pattern in which the ongoing Middle East war has repeatedly interrupted tanker traffic through the Strait of Hormuz, with effects now reaching petrochemical producers in Asia and the United States. Producers with long-haul feedstock dependence are more exposed to chokepoint delays than integrated suppliers with alternate sourcing.
Operators who buy ethylene, propylene, or polyethylene resins should ask suppliers for written confirmation of allocation and delivery timelines and assess alternate sourcing options. Procurement teams should confirm contract force majeure clauses with qualified counsel before assuming any relief or penalty.
The takeaway
Operators should treat the Strait of Hormuz as a live supply risk for petrochemical feedstocks and build delivery-delay buffers into procurement plans. Watch for Formosa's next disclosure on the duration of the shutdown and which units are affected before committing to new resin volumes.
