TOA Oil Kogyosho Co., LTD

TOA Oil Kogyosho Co., LTD, a for-profit Japanese corporation based in Yachiyo, Chiba, operates exclusively as a prime contractor delivering hazardous and non-hazardous waste collection, transportation, and disposal services to Department of Defense installations in the Pacific Region, with no subcontractor footprint.

The vendor's customer concentration is heavily skewed to a single agency. The Department of the Army Installation Management Command Pacific Region accounts for 94% of awards and $4.3 million of the combined $4.4 million potential value across all recent federal work, with the Department of the Air Force Pacific Air Forces and the Defense Finance and Accounting Service accounting for the remaining activity. TOA Oil operates two indefinite-delivery vehicles: IDC F6256202D0015 (5 task orders) and IDC FA520925D0003 (2 task orders, $324 thousand combined potential value). Recent delivery orders under these vehicles include a $164,364 firm fixed-price order awarded January 1, 2025, and a $159,219 order awarded December 1, 2025, both for collection, transportation, and disposal of grease, waste oil, and sludge at U.S. Army Garrison Japan installations in the Kanto Plain region, running through November 2025 and November 2026 respectively.

The vendor's capability portfolio is narrowly specialized: non-hazardous waste treatment and disposal (11 awards), hazardous waste treatment and disposal (3 awards), and support activities for oil and gas operations (2 awards), predominantly characterized by PSC codes for trash and garbage collection, sewage and waste operations, and waste treatment and storage. Award activity has been sparse and episodic — 17 total awards since 2002, with only two in 2025 and one in 2024. One award (combined potential value $159 thousand) reaches ultimate completion inside the next twenty-four months, presenting minimal recompete exposure. The vendor has obligated $3.1 million against combined potential value of $4.4 million, representing a 70% obligation rate, suggesting active contract performance against its overseas facilities support mandate.
