About this agency
Department of the Army Materiel Command Expeditionary Contracting Command Regional Contracting Office Yongsan 411th CSB, a sub-office within the Army's overseas acquisition hierarchy, procures supplies, services, and equipment in support of U.S. military operations and personnel stationed in the Korea region. The office conducts contracting on behalf of the regional command and its subordinate elements, with transactional authority over both tactical and administrative requirements.
The office has awarded 7,845 contracts cumulatively since 1988, with combined potential value of $178.9 million and combined dollars obligated of $600.3 million. Recent activity shows steady volume: the office issued 14 awards in 2022, 11 in 2023, 19 in 2024, 15 in 2025, and 16 year-to-date in 2026. The most recent recorded award dates to July 2, 2026. Nine percent of awards in the last five years carry no reported potential value, consistent with Schedule task orders, BPA calls, modifications, or below-threshold purchase orders typical of overseas regional contracting.
Over the last five years, competitive concentration is highly concentrated among the top five primes by award count, which collectively hold 94 percent of recent awards. Bosung Industry Co., LTD. dominates by count with 55 awards valued at $736 thousand combined potential value. Hankuk Vehicles Co., LTD. follows with 14 awards ($61 thousand), and three smaller vendors split the remaining competitive share. By potential value, the competitive picture shifts: A Joint Stock Corporation Jung Won Tour holds a single $5.8 million award, while Bosung Industry transacts heavily through smaller awards. The contracting office has awarded 1,284 distinct prime contractors cumulatively across its portfolio history.
Across all 7,845 awards cumulatively, 7,836 awards carry no set-aside designation (100%), with only 7 awards designated small-business and 2 awards designated Competitive 8(a). The office operates almost exclusively through unrestricted procurements, consistent with overseas regional-contracting practice where vendor capacity and geographic proximity often supersede domestic small-business preferences.
