Chuo Bussan Co.,Ltd.

Chuo Bussan Co., Ltd., a for-profit Japanese corporate entity headquartered in Fussa, Tokyo, supplies specialized equipment and materials to U.S. military installations in the Pacific region as a prime contractor on full-and-open federal contracts, with no reliance on small business set-asides. The vendor operates exclusively in the prime role (100% of awards) and competes without SBA certifications.

Chuo Bussan's capability footprint centers on equipment procurement and base maintenance materials for Pacific-region Department of Defense installations. The vendor's work spans electrical and power infrastructure (generators, DC power supply units, frequency converters), thermal systems (combined heat plant materials, liquid ammonia), HVAC equipment, and facility consumables (construction materials, landscaping equipment, LED lighting). Representative work includes an April 2026 BPA call order valued at $149,958.63 from Pacific Air Forces for combined heat plant materials at Yokota Air Base in Japan (ultimate completion August 31, 2026), a June 2025 purchase order valued at $124,612.05 from Department of the Army Pacific Region for a generator at Camp Zama (ultimate completion June 15, 2026), and an August 2024 purchase order valued at $44,617.78 from Pacific Air Forces for site survey equipment (ultimate completion November 12, 2024).

Customer concentration is acute and geographically focused. Pacific Air Forces accounts for 46 awards and $5.7 million of combined potential value; the broader Department of the Air Force holds 63 awards and $751 thousand combined potential value; Department of the Army Installation Management Command Pacific Region represents 11 awards and $626 thousand; Defense Logistics Agency Troop Support Pacific holds 3 awards valued at $107 thousand. Together these five customer designations cover 97% of recent award count and 99% of combined potential value. The top parent vehicle is Indefinite Delivery Contract F6256299A0007 (21 task orders), followed by Blanket Purchase Agreement FA520923A0017 (8 task orders, $845 thousand combined potential value) and Indefinite Delivery Contract F6256294A0017 (7 task orders). Chuo Bussan also holds a single-award $4 million BPA with Pacific Air Forces running through September 2026 specifically for combined heat plant materials and services at Yokota Air Base, under which multiple BPA call orders have been executed.

Award activity has been modest and irregular—two awards in 2022, four in 2023, six in 2024, four in 2025, and one in 2026—with combined potential value of $7.9 million across 129 total awards since 1997. Only one award (valued at approximately $150 thousand) faces ultimate completion in the next twenty-four months. The vendor operates with no subcontractor footprint; all awards are prime contracts. Category concentration clusters on motor and generator manufacturing (10 awards), chemicals including ammonia (9 awards), hardware manufacturing (4 awards), and air-conditioning equipment (3 awards), with top PSC codes reflecting generators and generator sets (34 awards) and chemicals (9 awards).
