S-Oil Corporation

S-Oil Corporation's Fuel Product Overseas Marketing Team Division supplies naval distillate (F76) and aviation turbine fuels (JP5 and JA1) to the Defense Logistics Agency Energy as a prime contractor under single-award Indefinite Delivery Vehicle contracts, with no subcontractors and no small business set-aside participation. S-Oil is an international organization and for-profit entity headquartered in Seoul, South Korea at 192 Baekbeom-ro, Mapo-gu, structured as a South Korean oil refiner and operates exclusively as a prime contractor (100% of awards).

Customer concentration is extreme and monolithic. Defense Logistics Agency Energy accounts for 286 of 295 awards (97% coverage) and $14.71 billion of the $15.19 billion combined potential value. The remaining eight awards, attributed to Defense Logistics Agency in the source, align with DLA Energy operations. This is a single-customer enterprise serving one federal agency through one division.

S-Oil holds five active IDV vehicles under the Western Pacific Purchase Program (WESTPAC). The most recent, awarded November 20, 2025, carries a $736.7 million ceiling through December 31, 2026, authorizing procurement of approximately 201.8 million gallons of F76 naval distillate, 140.5 million gallons of JP5 aviation turbine fuel, and 280.4 million gallons of JA1 aviation turbine fuel. Prior vehicles include a $767.4 million IDV awarded December 13, 2024 (through December 31, 2025, now expired), an $869.9 million contract through December 31, 2024, a $681.6 million contract through December 31, 2023, and a $171.9 million contract through December 31, 2022. All five vehicles carry single-award, non-competitive status. The five highest-activity parent vehicles collectively account for 136 task orders and $2.54 billion in combined potential value.

Capability work is exclusively bulk fuel delivery. Representative delivery orders include a $37.5 million order for F76 naval distillate completed April 15, 2026; a $34.7 million order for F76 completed March 20, 2026; a $23.8 million order for aviation turbine fuel completed March 5, 2026; and a $26.5 million order for aviation turbine fuel completed July 2, 2025. All contracts employ fixed-price structures with economic price adjustment provisions. Performance occurs exclusively in South Korea, where S-Oil maintains refining and distribution infrastructure. Delivery modes include tanker, barge, truck, railcar, and pipeline. All recent delivery orders carry 15 to 90-day performance periods.

Activity is stable and recurring. The source records 14 awards in 2022, 30 in 2023, 29 in 2024, 31 in 2025, and 6 in 2026 (through March 26). The combined potential value across all 295 awards reaches $15.19 billion, with $7.14 billion obligated to date (47% execution rate). S-Oil has maintained this role as DLA Energy's primary strategic fuel supplier in the Western Pacific theater since at least 2004, receiving over 50 delivery orders totaling more than $1 billion in cumulative value since 2019 alone. The recent activity trajectory reflects sustained high-volume ordering: 23 delivery orders issued under the current WESTPAC IDV as of the most recent data point total approximately $428 million in cumulative obligations.

S-Oil competes exclusively full-and-open, non-set-aside. No small business, HUBZone, SDVOSB, WOSB, 8(a), or other SBA set-aside designation applies to any award in the source. NAICS concentration is 285 awards in Petroleum Refineries (primary), with two awards in Petroleum and Petroleum Products Merchant Wholesalers. PSC concentration is Liquid Propellants and Fuels, Petroleum Base (173 awards) and Fuel Oils (122 awards).
