Donald E. Harman Co

Donald E. Harman Co, operating through its Harman Company Division, is a Richardson, Texas-based small business supplying mechanical power transmission components and automotive spare parts to the Defense Logistics Agency (DLA) as a prime contractor exclusively under total small business set-asides. The company is a family-owned, for-profit entity that has held federal contractor registration since February 2002 and operates across NAICS categories including speed changer and gear manufacturing (29 awards), mechanical power transmission equipment manufacturing (20 awards), and metal valve and pipe fitting manufacturing (18 awards).

The company's capability portfolio centers on defense logistics consumables: rotating air unions, straight flange adapters, disk brake shoes, clutch assemblies, internal gears, hub bodies, control assemblies, bolts, and related power transmission components. Representative recent work includes a $64,961 total small business set-aside purchase order from DLA Land and Maritime for 19 units of straight flange adapters awarded August 2025; a $53,880 total small business set-aside award for 15 straight flange adapters from DLA Land and Maritime issued January 2026; a $175,200 total small business set-aside purchase order for clutch assemblies from DLA Land and Maritime in December 2022; and three single-award indefinite delivery contracts, each with a $250,000 ceiling, awarded by DLA Land and Maritime in October 2022, October 2023, and May 2025 to enable delivery-order procurement of clutch assemblies, control assemblies, and brake components on an as-needed basis.

Customer concentration is extreme: DLA Land and Maritime accounts for 96 of 115 awards (3.2 million dollars combined potential value), with DLA Aviation placing 7 awards ($134 thousand), the Department of the Treasury Bureau of Engraving and Printing issuing 6 awards ($15 thousand), and three other DoD and Navy components sharing the remainder. The top three vehicles are single-award indefinite delivery contracts (IDC SPE7L320D61KN carrying 3 task orders worth $37 thousand, IDC SPE7L320D61XX with 3 task orders totaling $26 thousand, and IDC SPE7L324D60DL with 1 task order valued at $4 thousand), all supplied through DLA Land and Maritime. The company competes entirely under total small business set-asides; no full-and-open awards appear in the source footprint.

Activity has accelerated modestly: four awards in 2022, six in 2023, ten in 2024, and thirteen in 2025, with two awards recorded in 2026. Combined potential value stands at $3.4 million across all 115 awards, with $1.9 million obligated (56% realization). The vendor operates exclusively as a prime contractor; no subcontract awards appear in the source data. The company holds no subsidiary teaming relationships, multi-agency GWACs, or vehicles outside the DLA Land and Maritime IDC portfolio. Harman Company Division's business model is transactional and narrow—small dollar-value purchase orders and delivery orders against single-award IDCs for mechanical spare parts required by military fleet maintenance operations, with no exposure to systems integration, engineering services, or non-DLA customer bases.
