Seojin TNS Co., LTD

Seojin TNS Co., LTD, a South Korea-based facility maintenance company, provides Level 2 custodial and cleaning services to the Pacific Air Forces across military installations in the Asia-Pacific region as a prime contractor on a single-award Indefinite Delivery Contract. The vendor competes on an unrestricted, non-set-aside basis and holds no SBA certifications. All ten awards in the source data are prime contract vehicles issued by Pacific Air Forces, with no subcontract activity.

Seojin TNS operates exclusively under a single IDC awarded by Pacific Air Forces on February 1, 2024, valued at $3.39 million with a performance period through December 31, 2028. The contract scope encompasses restroom and locker room cleaning, trash removal, sweeping, mopping, vacuuming, carpet shampooing, spot cleaning, and dusting services. Delivery orders under this IDC have ranged from $7,877 for special event facility services to $640,355 for Level 2 restroom and locker room cleaning through December 2025. Representative work includes a $171,675 three-month custodial services delivery order at Osan Air Base covering January through March 2026, a $230,059 facility cleaning delivery order completed in July 2024, and a $12,786.91 delivery order issued February 17, 2026, for custodial service at Osan Air Base in support of Exercise USF 26. Eight delivery orders totaling $1.3 million in combined obligated dollars have been issued under the parent IDC to date.

Customer concentration is absolute: Pacific Air Forces accounts for 100% of the vendor's award footprint across all ten awards and the full $4.6 million in combined potential value. The vendor's activity peaked in 2024 with five awards, declining to three in 2025 and two in 2026 (through mid-February). Combined obligated dollars stand at $1.3 million against $4.6 million in combined potential value, indicating 27% drawdown to date on the IDC ceiling. The vendor executes all work independently without identified subcontractors, demonstrating internal capacity to manage facility maintenance operations across multiple PACAF installations in South Korea. Performance is priced on a firm fixed-price basis across all delivery orders.
