South Korea Chemical Watch: H1 2026 Closing Review of the Force Majeure Wave

South Korea's petrochemical industry closes H1 2026 having experienced one of the most operationally challenging periods in its recent history. Unlike many producing regions where disruptions primarily affected exports, Korean producers faced significant feedstock shortages that forced widespread force majeure declarations across multiple product categories.

For procurement professionals, H1 was defined not only by reduced production but also by contractual uncertainty. As Gulf LPG and naphtha supplies gradually recover, the industry's attention is shifting from crisis response toward the orderly resumption of commercial obligations, making H2 2026 a critical transition period for both producers and international buyers.

South Korea Experienced the Broadest Force Majeure Wave

During the Hormuz disruption, South Korea issued the most extensive wave of force majeure declarations among major global chemical producers.

The country's petrochemical industry relies heavily on imported naphtha and LPG feedstocks. When supply disruptions affected these critical raw materials, many producers faced little choice but to reduce operating rates and invoke contractual force majeure provisions.

Unlike short-term production interruptions, these declarations had legal and commercial consequences extending well beyond manufacturing operations.

For buyers, delivery schedules, contractual obligations and inventory planning all required immediate reassessment.

Feedstock Constraints Hit Both Naphtha Crackers and PDH Plants

South Korea's diversified petrochemical sector depends on two major feedstock streams.

Naphtha crackers produce essential building blocks such as ethylene, propylene and aromatic products, while propane dehydrogenation (PDH) units convert imported LPG into propylene for downstream manufacturing.

Disruptions to both supply chains created simultaneous pressure across the industry.

Products affected included:

• Polyethylene used in packaging and industrial applications.

• Polypropylene serving automotive, consumer goods and healthcare markets.

• Ethylene derivatives supporting plastics, solvents and synthetic materials.

• Propylene-based chemicals produced through PDH operations.

• Numerous downstream specialty chemicals dependent on integrated feedstock availability.

The widespread nature of these disruptions explains why force majeure declarations extended across multiple companies and product families rather than remaining isolated to individual facilities.

Force Majeure Is More Than an Operational Issue

While force majeure often begins with production constraints, its long-term impact is primarily commercial.

These declarations alter contractual obligations, delivery commitments and customer expectations. Even after production resumes, suppliers and buyers must work together to determine how contracts will transition back to normal performance.

Several issues typically require attention:

• Confirmation of force majeure termination dates.

• Updated production schedules.

• Revised shipment priorities.

• Outstanding contractual obligations.

• Inventory allocation for existing customers.

For procurement teams, early engagement with suppliers can significantly reduce uncertainty during the recovery phase.

Improving Feedstock Supply Supports Recovery

Conditions entering H2 2026 are considerably more favourable than those experienced during the peak of the crisis.

The gradual recovery of Gulf LPG and naphtha exports is improving feedstock availability for Korean producers while reducing pressure on international procurement markets.

Several positive developments are supporting recovery:

• More consistent availability of imported naphtha.

• Increasing LPG shipments supporting PDH operations.

• Improved shipping reliability across regional trade routes.

• Better visibility for production planning.

These developments allow producers to focus on progressively restoring operating rates instead of managing emergency feedstock shortages.

Recovery Will Depend on Commercial Coordination

Although feedstock conditions are improving, the end of force majeure declarations will not occur automatically.

Each producer must coordinate closely with customers to determine how contractual performance will resume.

Companies including LG Chem, Lotte Chemical and Hanwha Solutions are expected to prioritise existing contractual commitments before expanding availability for new business.

For buyers, proactive communication is likely to prove more valuable than waiting for market-wide announcements.

The Wind-Down of Force Majeure Begins

As feedstock availability improves, South Korea's petrochemical industry is entering the formal transition from crisis management to commercial normalisation.

The lifting of force majeure declarations is expected to occur progressively rather than simultaneously across all producers and product lines. Individual facilities will resume contractual performance according to feedstock availability, operating rates and customer commitments.

This phased approach should improve supply predictability while allowing producers to stabilise operations before returning to normal commercial activity.

What International Buyers Should Do Now

For companies with active supply agreements affected by force majeure, H2 begins with an important commercial opportunity.

Rather than waiting for individual shipment notifications, buyers should engage directly with Korean suppliers to establish clear expectations for contract resumption.

Priority actions include:

• Confirm the expected termination of force majeure declarations for each affected contract.

• Request updated production and shipment schedules for Q3 deliveries.

• Verify product allocation priorities for existing customers.

• Review contractual obligations that may require revised delivery dates or amended schedules.

• Coordinate logistics planning with freight providers as export volumes continue recovering.

Early communication can help minimise uncertainty while strengthening long-term supplier relationships.

Korean Producers Will Prioritise Existing Commitments

As production gradually returns, Korean producers are expected to focus first on fulfilling contractual obligations before allocating significant volumes to the spot market.

This approach reflects established commercial practice following major operational disruptions.

For buyers with existing agreements, this provides a meaningful advantage over new market participants seeking immediate availability.

Companies with long-standing commercial relationships are likely to receive earlier confirmation of delivery schedules as producers progressively restore operating rates.

Feedstock Recovery Supports Better Operating Rates

The gradual recovery of Gulf naphtha and LPG exports is improving the outlook for Korean petrochemical producers.

Although operating rates are unlikely to return immediately to pre-crisis levels, improving feedstock availability provides greater confidence for production planning throughout H2.

Several factors support this recovery:

• Increasing imports of naphtha for steam crackers.

• Improved LPG availability supporting PDH facilities.

• More stable international shipping conditions.

• Better visibility for procurement and production scheduling.

These improvements reduce the operational uncertainty that characterised much of the first half of 2026.

The Market Outlook for H2 2026

South Korea's petrochemical sector enters H2 2026 under significantly more favourable conditions than those experienced during the peak of the Hormuz disruption.

The industry's challenge is no longer securing sufficient feedstock to maintain operations. Instead, attention has shifted toward restoring contractual performance, rebuilding customer confidence and progressively increasing production as supply conditions continue improving.

For international buyers, the most important priority is active commercial engagement. Companies with force majeure-affected agreements should work closely with Korean producers to confirm resumption schedules, validate Q3 delivery commitments and maintain flexibility while operations continue normalising.

The experience of H1 2026 also reinforces an important lesson for global procurement. Strong supplier relationships, diversified sourcing strategies and proactive contract management remain essential components of supply chain resilience when geopolitical events disrupt international chemical markets.
