TSN Co., LTD.

TSN Co., LTD. It Department Division, a for-profit Asian-Pacific American-owned company headquartered in Seoul, South Korea, supplies network infrastructure materials, IT equipment, and facility maintenance services to the Department of Defense in the Korea region as a prime contractor under full-and-open solicitations with no set-aside designations. The company operates exclusively as a prime (100% of its 262 recent awards) and does not subcontract. Over the past several years, TSN Co., LTD. has delivered more than $268.2 million in combined potential value across fiber optic cable installations, network switch procurement, uninterruptible power supply maintenance, cable management components, and electrical infrastructure upgrades to U.S. military installations throughout South Korea.

The vendor's customer footprint is heavily concentrated within the Department of the Army and its regional commands. The top five Army customers by award count account for 76% of recent awards, led by the Department of the Army (96 awards, $2.8 million combined potential value), the Department of the Army Cyber Command (33 awards, $2.2 million), the Department of the Army Installation Management Command Korean Region (24 awards, $481 thousand), the Department of the Army Pacific Command (24 awards, $1.6 million), and the Department of the Army Materiel Command Expeditionary Contracting Command Regional Contracting Office Yongsan 411th CSB (22 awards, $16 thousand). However, the dollar rankings diverge sharply: the Department of the Army Corps of Engineers Engineering District Far East anchors the portfolio with just three awards but carrying $257.9 million in combined potential value — a massive outlier that likely represents one or more indefinite delivery contracts or long-term maintenance agreements. Beyond Army components, TSN Co., LTD. has served the Marine Corps, the Department of the Army Medical Command, and smaller numbers of other federal agencies.

TSN Co., LTD. places task orders under five named Army indefinite delivery contracts, with the largest activity under W91QVN10D0031 (6 task orders, $470 thousand combined potential value). Representative recent work includes a $737.6 thousand definitive contract with Army Cyber Command (awarded September 2022, completing September 2027) for preventive maintenance services at Camp Walker covering 16 AICS units and five UPS units with four-hour service-call response requirements; a $212.5 thousand purchase order from Army Medical Command (September 2024) for network upgrade materials including fiber optic cables, cabinets, and power distribution units to support overseas base modernization; and a $26.2 thousand purchase order from the Department of Defense Korean Region (July 2026) for material and upgrade of gates in Area 1 from copper to fiber backbone for the AIE system. Activity has been volatile — five awards in 2021, three in 2022, five in 2023, three in 2024, and one in 2026 — with only two awards (combined potential value $871 thousand) facing ultimate completion within the next twenty-four months, indicating limited near-term recompete exposure. The vendor's NAICS and PSC profile centers on fiber optic cable manufacturing and installation (28 awards by top NAICS), electrical contracting (18 awards), communications equipment repair and maintenance (14 awards), and cable assemblies (17 awards by PSC).
