About Miller-Stephenson Chemical Co Inc.
Miller-Stephenson Chemical Co Inc., a Danbury, Connecticut-based manufacturer of specialty chemical products for defense and federal applications, operates as a Subchapter S corporation supplying lubricants, cleaners, adhesives, and preservative compounds to the Department of the Navy, Department of the Army, and Department of the Air Force as a prime contractor under full-and-open (non-set-aside) purchase orders. The company competes exclusively outside set-aside vehicles and has not secured positions on government-wide IDIQs or GWACs.
Miller-Stephenson's federal portfolio spans 254 prime awards dating to 1996, with recent work concentrated in aircraft and shipboard lubricants, specialty cleaners, and industrial chemical compounds for military maintenance and operations. Recent representative awards include a $110,466.90 firm fixed-price purchase order from Naval Supply Systems Command for Krytox 143AB lubricating oil in 0.5 kg cans designated as Special Emphasis material (Level I) for critical shipboard systems (awarded July 9, 2025, performance at Danbury facility), a $56,532.79 purchase order from Naval Supply Systems Command for aircraft grease (awarded December 8, 2025, completion June 12, 2026), and a $10,917.90 purchase order for Chemours Company Krytox 240AB compliant with MIL-PRF-27617 type II specifications (awarded July 15, 2025, completion January 20, 2026). The company also supplies aerosol cleaner extensions and brush attachments through the General Services Administration and holds a position on GSA BPA GS06FMILST with three task orders.
Customer concentration centers on Navy logistics and supply operations. The Department of the Navy Naval Supply Systems Command represents the top funding source by potential value ($1 million across 16 awards, 67% of recent dollars), while Naval Sea Systems Command ranks highest by award count (63 awards, $191 thousand combined potential value). The Department of the Army Materiel Command (including Communications Electronics Command, TACOM Life Cycle Management Command, and Joint Munitions Command) and the Department of the Air Force Air National Guard account for the remaining portfolio. These top five customer offices cover 57% of awards by count and 89% of combined potential value.
Product concentration reflects military demand for lubricants and cleaners. The company's top NAICS categories are all-other miscellaneous chemical product manufacturing (104 awards) and adhesive manufacturing (56 awards), with petroleum lubricating oil and grease manufacturing representing 12 awards. PSC coding shows 78 awards for cleaning and polishing compounds, 66 for oils and greases (cutting, lubricating, and hydraulic), and 41 for preservative and sealing compounds. Recent annual activity remains sparse — one award in 2021, one in 2022, two in 2024, three in 2025 — with combined obligated dollars of $1.7 million across the entire portfolio. All performance occurs at the company's Danbury, Connecticut facility. Miller-Stephenson has no subcontractor footprint in the federal award data and operates without subcontractors on its primes.
