About CSE Corporation
CSE Corporation, a Pennsylvania-based manufacturer of industrial safety equipment, supplies self-contained self-rescuer (SCSR) breathing devices and related respiratory protection equipment to federal mining safety and occupational health agencies as a prime contractor exclusively, operating entirely outside the set-aside universe across a small customer footprint.
CSE's business is narrowly specialized in SCSR design, manufacturing, and logistics. The company's Self-Rescuer Long Duration (SRLD) model — the incumbent product for MSHA — is a battery-powered breathing device rated for 60 minutes of emergency air supply, carrying NIOSH and MSHA approvals and a 5-year service life. Representative contracts include a $304,355.90 Total Small Business purchase order awarded by the Mine Safety and Health Administration (MSHA) in April 2026 for delivery of 226 SRLD units and disposal of 554 expired devices across nine MSHA district locations in West Virginia, a $221,624.10 Total Small Business purchase order from MSHA in June 2025 for SRLD devices serving both MSHA's Enforcement Division and the Public Sector Health and Training Center Tech Support Division, and a $336,343.71 firm fixed-price contract from MSHA in July 2021 to replace approximately 300 expiring units with pouches and disposal services. CSE also manufactures trainer units demonstrating SCSR operation and supplies related safety products including gas detection systems.
Customer concentration is severe and two-tiered by dollar value and volume. MSHA dominates both dimensions — 38 awards totaling $4.8 million combined potential value (68% of the portfolio) — with the Centers for Disease Control and Prevention Pittsburgh (25 awards, $983 thousand) far behind. The Department of the Interior, CDC Morgantown, and CDC Office of Acquisition Services round out the active set at one award each. The two customer rankings track closely; MSHA's dominance spans both order count and dollars. CSE has placed four task orders under the MSHA Indefinite Delivery Contract DOLMSH15D0006 carrying $916 thousand in combined potential value. All 75 recent awards in the source are classified to mining or occupational safety NAICS codes — Mining Machinery and Equipment Manufacturing (15 awards), Bituminous Coal Underground Mining (10), Support Activities for Coal Mining (9) — and 40 of the 75 fall under the Safety and Rescue Equipment PSC.
Activity is sparse and flat. The past five years show only seven awards (2022: 2, 2023: 1, 2024: 1, 2025: 2, 2026: 1), reflecting the capital-equipment, replacement-cycle nature of SCSR procurement. One award with a combined potential value of $143 thousand reaches ultimate completion inside the next twenty-four months. CSE operates as a pure prime with zero subcontract engagement in the source data. The company has no seat on government-wide acquisition vehicles, GWACs, or agency BPAs; all work flows through MSHA and CDC spot purchase orders and the single MSHA IDIQ.
