About the company
Distribution Specialists Inc., doing business as DSI, supplies fluid condition monitoring equipment and diagnostic instruments to defense logistics and Navy operations as a prime contractor on full-and-open purchase orders. The Sterling, Virginia-based for-profit Subchapter S corporation competes without set-aside designations on most work, though a small share of awards carry Total Small Business set-asides; the vendor does not hold SBA 8(a), HUBZone, SDVOSB, or other formal certifications.
DSI's capability portfolio centers on viscometers (tube-type and heated), water-testing reagent sets, electronic analyzers, oil condition test kits, and accessories such as end plugs, caps, power cords, and technical manuals. These supplies support military readiness through the Defense Logistics Agency's Medical Supply Chain and Land and Maritime divisions and the Department of the Navy's supply systems. Representative work includes a $246,600 water-testing reagent set order from Naval Supply Systems Command (July 2022), a $129,150 reagent set purchase order from Naval Supply Systems Command (July 2025), a $41,000 water-testing reagent set from DLA Land and Maritime under Total Small Business set-aside (April 2024), a $28,700 reagent set from DLA Land and Maritime under Total Small Business (December 2023), and a $21,240 water-testing reagent set from DLA under Total Small Business (December 2025). The vendor also supplies individual instruments valued between several hundred and roughly $18,500 per transaction.
Customer concentration sits heavily with DLA divisions. The Defense Logistics Agency Troop Support Medical accounts for 136 awards with $442 thousand combined potential value; DLA Land and Maritime holds 57 awards with $510 thousand; and Department of the Navy Naval Supply Systems Command carries 7 awards with $495 thousand. These three customers represent 89% of award count and 94% of combined potential value. DLA Aviation and Naval Sea Systems Command round out the active set. The vendor has served 10 distinct federal agencies over its award history.
Recent activity shows growth from 13 awards in 2022 to 19 in 2025, with 7 awards issued in 2026 year-to-date. One award (the NAVSUP reagent set valued at $129,150) reaches ultimate completion inside the next twenty-four months. All 236 awards in the source are prime contracts; DSI carries no subcontract relationships documented in the award record. The combined potential value across all awards is $1.6 million, though obligated dollars total $2.5 million, indicating repeated orders and task completions exceeding initial contract ceilings. The vendor has maintained continuous federal registration since February 2002 and competes predominantly on small-dollar transactions ranging from under $200 to roughly $250,000, with the bulk of awards issued as purchase orders under DLA's medical and maritime supply chains.
