Main Market: Asia – Pacific Industrial and Export Hubs
S-Oil target market centers on South Korea and neighboring North Asian manufacturing hubs (China, Japan) because ~60% of refined-product volumes in 2025 flowed into export channels serving these economies, driven by petrochemical feedstock demand and short maritime routes.
Secondary Markets: Southeast Asia, Oceania, US & Europe

Where S-Oil Is Strongest: B2B Petrochemicals and Export Logistics
S-Oil customers are predominantly industrial buyers: refining & petrochemical buyers and fleet/commercial fuel accounts, accounting for the bulk of revenue and ~70% of margin-contributing volumes in 2025 thanks to integrated refinery – chemical operations and port connectivity.
