USI Inc.

USI Inc., a woman-owned small business based in Madison Heights, Michigan, manufactures industrial components and mechanical parts for the Department of Defense as a prime contractor (95% of recent awards) and subcontractor on ground-vehicle programs. The company is a for-profit manufacturer specializing in valves, wiring harnesses, manifolds, clutch assemblies, and related mechanical components that support military aviation, ground vehicles, and supply-chain operations. USI competes predominantly in full-and-open procurement, though it holds multiple Total Small Business set-asides within the Defense Logistics Agency.

USI's customer base is heavily concentrated within the Defense Logistics Agency. The top five funding agencies account for 95% of recent awards, led by DLA Land and Maritime (181 awards, $4.8 million combined potential value), which sources safety relief valves, fueling manifolds, and regulating valves as source-controlled items for distribution networks. DLA Aviation accounts for 40 awards and $1.5 million in combined potential value through multiple indefinite delivery contracts for wiring harnesses and related aviation components. The Army Materiel Command's Detroit Arsenal contracting command and TACOM Life Cycle Management Command follow, with 10 combined awards anchoring $5.1 million in potential value, driven by a single-award IDC for clutch assemblies (ceiling $1.5 million) awarded in 2019 and multiple delivery orders against it. Recent representative prime awards include a $207 thousand purchase order from DLA Land and Maritime (May 2023) for 78 safety relief valves, a $263 thousand delivery order from Army Materiel Command Detroit Arsenal (December 2022) for clutch assembly 2520-01-067-3899, and a $84.6 thousand purchase order from DLA Land and Maritime (July 2024) for safety relief valves in support of military operations. USI holds two single-award indefinite delivery contracts with DLA Aviation, each with a $250,000 ceiling — one awarded September 2025 for mechanical aviation components and another awarded November 2022 for wiring harnesses running through November 2026 — and issues delivery orders ranging from $5,000 to $10,000 per task against these vehicles.

Award activity has grown from four awards in 2022 to fifteen in 2024, with fourteen awards issued in 2025 and three through April 2026. Only three awards (combined potential value $331 thousand) reach ultimate completion within the next twenty-four months, reducing near-term recompete exposure. In its subcontractor role, USI supplies components and unspecified goods or services to General Dynamics Land Systems on multiple modifications and delivery orders related to M1A2 SEPV3 Abrams tank production and upgrades, including work on the fifth domestic delivery order upgrading M1A1 tanks to SEPV3 and production of 250 tanks for Poland. Across the portfolio, USI's capability concentration clusters in Industrial Valve Manufacturing (86 awards) and Fabricated Pipe and Pipe Fitting Manufacturing (40 awards), with secondary work in Military Armored Vehicle and Tank Component Manufacturing (14 awards) through the General Dynamics subcontracts. PSC coding reflects the same distribution — Valves, Nonpowered (96 awards) dominate, followed by Hose, Pipe, Tube, and Lubrication Fittings (54 awards). All work is performed at the contractor's Madison Heights facility, supporting the DOD's inventory and sustainment operations.
