Polimaster Inc.

Polimaster Inc., a Sterling, Virginia–based manufacturer of radiation measurement and detection equipment, supplies personal radiation detection units and related services to the Department of Homeland Security as a prime contractor under full-and-open competition, with no recurring set-aside designations across its federal footprint.

Polimaster operates as a for-profit corporate entity and has maintained SAM.gov registration since 2004. The company's federal work centers on radiation detection and measurement instruments classified primarily under NAICS 334515 (Other Measuring and Controlling Device Manufacturing), with secondary codes covering detection systems and analytical instruments. Polimaster competes exclusively as a prime — the source records no subcontract work — and across its recent award portfolio carries firm-fixed-price delivery orders for personal radiation detectors, training, accessories, and associated field services.

The company's customer base is heavily concentrated with the Department of Homeland Security. DHS CWMD (Countering Weapons of Mass Destruction) accounts for eight awards worth $214.7 million combined potential value, and DHS USCG (US Coast Guard) accounts for seventeen awards worth $4.2 million. The Army Acquisition Support Center's Joint PEO Chemical and Biological Defense anchors the remaining concentration with two awards totaling $8.28 billion in combined potential value, though obligated dollars against that line total only a small fraction. Across these three customer entities, 78% of Polimaster's awards are placed. The Department of State, the Postal Service, and the DHS Domestic Nuclear Detection Office round out an eight-agency customer set.

Polimaster places most work under the Securing the Cities - Personal Radiation Detectors (STC PRD) IDIQ contract, established in March 2021 with a $121.4 million potential value. Six task orders under STC PRD carry $3.3 million combined potential value and support first responder radiological and nuclear threat detection nationwide. Recent delivery orders include a $254,116.50 firm-fixed-price order from DHS CWMD in April 2026 for 150 personal radiation detection units, a $355,763.10 order in January 2026 for radiation detection devices, and a $569,915.50 order from August 2023 for personal radiation detectors. Polimaster also holds seats on Coast Guard indefinite-delivery contracts HSCG8408DAAS148, HSCG8413DBB5042, and 70Z08418DBB500800, with five, five, and four task orders respectively across those vehicles.

Award activity has been sparse in recent years — one award in 2022, one in 2023, one in 2024, and two in 2026 — reflecting a low-frequency order pattern under established IDIQ vehicles rather than new prime contract wins. All five of Polimaster's most recent delivery orders obligate less than $10 million combined, though the Army's Joint PEO Chemical and Biological Defense line carries optionality with a multi-billion-dollar ceiling.

The company is engaged in manufacturing and distributing radiation detection equipment for defense/homeland security customers, first responders, and commercial users (medical professionals, power plans, etc.). It also provides technical maintenance and repair services related to its products.
