GS Caltex Corporation

GS Caltex Corporation's Middle Product Team Division, a South Korean energy company based in Seoul, supplies aviation turbine fuel to the U.S. Department of Defense as a prime contractor on a portfolio of 292 federal awards worth $4.94 billion in combined potential value, competing on full-and-open basis with no set-aside designations. The vendor operates 100% as a prime contractor with zero subcontract exposure and delivers specialized aviation fuel grades (JA1 and JP5) exclusively to Defense Logistics Agency Energy under single-award indefinite delivery contracts covering the Western Pacific region, with place of performance in South Korea.

GS Caltex's customer concentration is extreme. Defense Logistics Agency Energy accounts for 148 awards carrying $4.39 billion in combined potential value — representing 89% of the vendor's total portfolio dollars and covering roughly 610 million gallons of aviation turbine fuel procurement annually. The second-tier customer, Defense Logistics Agency (non-energy component), holds 74 awards but with substantially lower per-award magnitude. The Department of the Army Materiel Command Expeditionary Contracting Command Regional Contracting Office Yongsan and the Departments of Army and Air Force round out the active set but remain minor by volume and value. No civilian agencies appear in the award portfolio.

The vendor's work flows through five parent IDCs. The largest is a $265.1 million single-award IDC (awarded October 31, 2023, performance through December 31, 2024) that spawned multiple delivery orders ranging from $16.9 million to $39.0 million each. A newer $172.5 million single-award IDC (awarded December 12, 2024, performance through December 31, 2025) replaced it for 2025 performance and has issued delivery orders valued at $21.4 million and $26.2 million. Most recently, on November 20, 2025, GS Caltex won a $129.7 million single-award IDC covering January 1, 2026 through December 31, 2026, under which DLA Energy issued an $80.3 million delivery order on February 26, 2026. Three additional parent vehicles (SPE60016D0453, W91QVN04A0038, SPE60218D0453) carry smaller combined values and likely represent legacy or subordinate fuel procurement programs. The five vehicles collectively show 92 task orders placed against them with material concentration on the top three.

Activity has grown sharply year over year, from two awards in 2022 and 2023 to eight in 2024 and six in 2025, with two awards recorded in 2026 to date. All delivery orders are priced as fixed-price with economic price adjustment to manage fuel-cost volatility. Recent representative awards include a $80.3 million delivery order (February 26, 2026, completion March 26, 2026), a $57.4 million delivery order (April 13, 2026, completion April 30, 2026), a $28.8 million delivery order (August 6, 2025, completion August 26, 2025), and a $26.2 million delivery order (January 31, 2025, completion February 21, 2025). The vendor's NAICS concentration is absolute: 150 of 167 awards (89%) fall under Petroleum Refineries (NAICS 324110), with secondary exposure to Petroleum and Petroleum Products Merchant Wholesalers. GS Caltex operates approximately 785,000 barrels of petroleum refining capacity daily from its South Korean facilities and has held a SAM.gov registration since August 2001.
