KUK JE Sang SA

KUK JE Sang SA, a South Korea-based for-profit corporate entity headquartered in Seoul, provides hoist, overhead crane, and sling inspection, testing, preventive maintenance, and repair services to the Department of the Air Force as a prime contractor operating exclusively in full-and-open (unrestricted) contracting, with no subcontract footprint.

KUK JE Sang SA's customer concentration is stark: Pacific Air Forces accounts for 39 of 96 awards and $2.4 million of the $2.9 million combined potential value across the vendor's recent award portfolio. The Department of the Army (split across the Materiel Command Expeditionary Contracting Command Regional Contracting Office and Installation Management Command Pacific Region) represents the next tier with 26 awards and $283 thousand in combined potential value, followed by the Defense Commissary Agency (4 awards, $79 thousand). This heavy Pacific Air Forces concentration reflects KUK JE Sang SA's core business: the vendor holds a single-award indefinite delivery contract with Pacific Air Forces for hoist and sling services at Osan Air Base, South Korea, awarded September 1, 2025, with a ceiling of $631,741.03 and performance through August 31, 2030. Pacific Air Forces has exercised two delivery orders against this contract since award — a base-year firm fixed-price order of $119,542.74 (September 1, 2025, through August 31, 2026) and a first-option-year order of $104,366.57 (September 1, 2026, through August 31, 2027). The underlying IDV replaced a prior single-award contract established August 19, 2020, against which Pacific Air Forces issued four delivery orders between September 2020 and September 2023 totaling $70,789.25.

The vendor's work is classified across maintenance and repair PSCs, with 66 of 96 awards coded to Maint/Repair/Rebuild Of Equipment–Materials Handling Equipment and 30 awards to Commercial and Industrial Machinery and Equipment Repair and Maintenance NAICS. Performance is located at Osan Air Base, South Korea, where KUK JE Sang SA inspects, maintains, and repairs thirty-nine hoists and overhead cranes and thirteen slings supporting flight line and cargo handling operations. The contractor must provide all labor, supervision, tools, parts, equipment, vehicles, and transportation resources and maintain compliance with Air Force Manual 91-203 and inventory tracking systems. Activity remains infrequent (one award per year on average over the past five years), with only one award reaching ultimate completion inside the next twenty-four months ($104 thousand combined potential value), though the base IDV ceiling of $631,741.03 remains exercisable through 2030. The Army's five multi-year IDVs (DAJB0301D0034, W91QVN04D0012, W91QVN15D0029, W90VN620D0001, W91QVN11D0026) collectively account for 69 task orders across the portfolio, representing KUK JE Sang SA's secondary customer stream for materials-handling equipment maintenance at Army installations in the Pacific region.
