DSA Detection LLC

DSA Detection LLC, a North Andover, Massachusetts-based manufacturer of security and detection equipment, operates as a prime contractor (99% of recent awards) under total small business set-aside designation, supplying explosive trace detection consumables, inert training materials, and security screening equipment to federal agencies. The company is a for-profit limited liability company structured as a manufacturer of goods; it has been registered in SAM.gov since 2006 and competes almost exclusively under small business set-asides.

Customer concentration is extreme and decision-flipping: the Transportation Security Administration accounts for 196 of the vendor's 275 total awards (83% of award count) and $51.1 million of the $58.5 million combined potential value (87% of dollars). The Department of Homeland Security broadly (including TSA, National Protection and Programs Directorate, and Office of Procurement Operations) anchors 91% of combined potential value across 200 awards. The Department of Justice Federal Bureau of Investigation, the Department of the Navy, and the Defense Logistics Agency are tertiary customers with low-dollar footprints. This concentration reflects DSA Detection's role as a specialized consumables supplier to aviation security operations: recent prime awards include a $64.5 thousand TSA purchase order (September 2025) for 6,000 packs of 500DT Explosive Trace Detection sample swabs for Kennedy International Airport; a $61.1 thousand TSA award (August 2025) for QSB220 ETD sample traps to Minneapolis-St. Paul and Denver international airports; a $44.85 thousand TSA award (August 2025) for sample traps to Miami International Airport; a $491.1 thousand Department of Homeland Security order (April 2022) for 40 inert covert security testing kits for Federal Protective Service red team operations; and a $48.6 thousand Department of Justice Federal Bureau of Investigation order (October 2023) for inert blasting caps. Most awards are firm fixed-price purchase orders with 30- to 90-day delivery windows.

DSA Detection's parent vehicles are TSA-administered blanket purchase agreements: the top three BPAs (HSTS0407AOSO004, HSTS0515AOSO906, and HSTS0512AOSO074) carry 165 combined task orders and $13.9 million in combined potential value. A Naval Sea Systems Command indefinite delivery contract (N0016406D8585) generated 17 task orders worth $315 thousand. The vendor's footprint is characterized by high-frequency, low-dollar transactions — the source records 275 total awards with a median purchase-order structure, reflecting TSA's consumables replenishment model rather than large system contracts.

Activity has accelerated in recent years: one award in 2022, two in 2023, two in 2024, six in 2025, and one in 2026 year-to-date. The source does not surface a recompete cliff. In its subcontractor role, DSA Detection delivers checkpoint maintenance and global security engineering and supply chain services to Leidos and General Dynamics Information Technology under threat-mitigation and inspection program task orders, though sub work represents only 1% of the recent award portfolio. The Service Contract Inventory dataset captures minimal activity — only two records across FY2022–FY2024 as a named subcontractor, with 0.1 FTE deliveries in each reported fiscal year — reflecting that DSA Detection's federal revenue model is goods procurement (purchase orders for physical equipment and consumables) rather than billable service delivery above the $150 thousand SCI reporting threshold.

DSA Detection manufactures and distributes its own brand of DHS-approved trace detection consumables used in the operation and maintenance of all explosive trace detection (ETD) instruments commercially available. DSA also manufactures X-ray correct inert explosive simulants, IED training aids, and test articles used in training screeners to identify threats and to verify security checkpoint equipment is properly identifying threats. DSA then combines all its products and training expertise into comprehensive and in-depth classroom training for threat recognition and security equipment operation, tailored to meet all levels of detection.
