About the company
MSE Supplies LLC, a minority-owned, Asian-Pacific American-owned limited liability company based in Tucson, Arizona, supplies specialized advanced materials, semiconductor substrates, and laboratory instrumentation to federal research and development agencies as a prime contractor (87% of recent awards) and as a subcontractor on defense electronics programs. The vendor competes on full-and-open (no set-aside) basis for the vast majority of its prime work, with one Total Small Business set-aside award; the company's customer agencies typically identify MSE Supplies as a sole-source provider of specialized materials and equipment, a pattern reflected across recent awards.
MSE Supplies' customer concentration is acute: the National Aeronautics and Space Administration's Shared Services Center accounts for 15 of 23 total awards and $648 thousand of $969 thousand combined potential value (67% of all awards by count, 67% of all dollars). The Department of the Navy's Office of Naval Research holds five awards valued at $58 thousand, while the Department of Commerce National Institute of Standards and Technology, the Navy's Naval Sea Systems Command, and the Defense Advanced Research Projects Agency round out the active set with one award each. The top two customers by dollar value track the top two by award count — a concentration signal — with NIST's single award ($247 thousand) elevating its potential-value rank above ONR despite ONR's five-award volume.
Capability portfolio centers on homoepitaxially grown silicon carbide (SiC) and gallium nitride (GaN) semiconductors, sapphire and ceramic substrates, hydrogen gas generators, hot isostatic presses, ultrasonic welding machines, and benchtop laboratory heat presses. Representative prime awards include a $70 thousand sole-source purchase order from NASA's Shared Services Center (December 2024) for homoepitaxially grown N-type and P-type 4H-SiC on semi-insulated substrates supporting propellant production research; a $31.7 thousand sole-source award from NASA (August 2025) for a high-capacity alkaline hydrogen generator at 0.4 megapascals purity exceeding 99.999% supporting Mars Propellant Production proof-of-concept; a $22.2 thousand award from the Shared Services Center (August 2025) for a 60-ton automatic hot isostatic press; and a $16.4 thousand Total Small Business purchase order from Naval Sea Systems Command (May 2025) for a glove-box-compatible MSE Pro 800W ultrasonic welding machine for inert-gas environments. The vendor's primary NAICS codes span Semiconductor and Related Device Manufacturing (6 awards), Other Electronic Component Manufacturing (5 awards), and Analytical Laboratory Instrument Manufacturing (4 awards), with PSC concentration in Laboratory Equipment and Supplies (10 awards) and Miscellaneous Fabricated Nonmetallic Materials (6 awards).
Recent activity has grown from two awards in 2022 to six in 2024, with four awards in 2025 and one so far in 2026. In its subcontractor role, MSE Supplies delivers customized piezoelectric langasite crystals to BAE Systems on the High Operational Temperature Sensors Program and fiber-optic components and advanced substrates to Raytheon on classified or proprietary electronics development efforts. Combined dollars obligated ($1.1 million) exceed combined potential value ($969 thousand) by 13 percent, indicating actual invoiced revenue has run above contract ceiling projections in this portfolio.
