Samchong Corporation

Samchong Corporation, a for-profit South Korean company established in 2007 and headquartered in Pyeongtaek, Gyeonggi-do, operates as a prime contractor (100% of recent awards) providing portable latrine rental, cleaning, maintenance, pump-out, septic tank servicing, and debris removal for U.S. military installations in South Korea. The vendor competes full-and-open with no set-aside designations across its federal footprint.

Samchong's customer base is heavily concentrated with the Department of the Air Force, Pacific Air Forces, which accounts for 89 of 155 total awards and $9.1 million of the $15.6 million combined potential value across the portfolio. The Department of the Army Installation Management Command Pacific Region places the second-largest volume at 30 awards with $3.6 million combined potential value, followed by smaller engagements with the Department of the Army Pacific Command ($1.3 million across two awards) and the Department of the Army at $1.3 million. These top three customers represent 90% of combined potential value and 96% of award count. The concentration reflects Samchong's specialized focus on wastewater and sanitation services at forward-deployed U.S. military installations, with place of performance exclusively at Osan Air Base, South Korea.

Samchong's primary vehicle holding is a single-award Indefinite Delivery Contract with Pacific Air Forces, valued at $819,214.97 and effective through June 15, 2029, solicited by the Army Contracting Command. Under this IDC framework, PACAF has issued multiple delivery orders for removal, cleaning, and disposal of portable latrines, grease traps, septic tanks, and lift stations serving 37 portable latrines, 17 grease traps, 14 septic tanks, and 22 lift stations at the installation. Representative delivery orders include a $198,756.80 firm-fixed-price annual contract awarded April 16, 2025 (completion June 15, 2026); an $8,325.33 order issued May 9, 2025 for portable latrine support for the Osan Air Show (completion May 12, 2025); and a $2,495.43 order issued March 2, 2026 for portalets septic services (completion March 20, 2026). Samchong also holds multiple Army IDCs and BPAs for comparable sanitation services at Army installations in the Pacific region. The top five parent vehicles collectively account for 102 task orders and $4.2 million combined potential value.

Award activity has been episodic — one award in 2023, five in 2024, four in 2025, and one in early 2026 — with a combined potential value of $15.6 million and $6.7 million obligated to date (43% of potential value). The vendor's work spans Septic Tank and Related Services (108 awards, the dominant NAICS category), Solid Waste Collection (29 awards), and smaller volumes of sewage treatment and miscellaneous waste management work.
