Notice of Intent to Sole Source Colormetric Test Kits

The Transportation Security Administration (TSA), part of the Department of Homeland Security, has issued a Notice of Intent to Sole Source colorimetric test kits for airport security operations. The notice pertains to TSA ECP Test Kits manufactured exclusively by DetectaChem, which have been selected as the mandatory replacement for existing colorimetric testing equipment across all airports nationwide. The TSA conducted a comprehensive evaluation of multiple state-of-the-art colorimetric kits and determined that DetectaChem's solution provided superior performance in four critical areas. The agency has classified this procurement under NAICS code 334516 for Analytical Laboratory Instrument Manufacturing and PSC code 6630 for Chemical Analysis Instruments. The notice was posted on August 26, 2025, with responses due by September 22, 2025.

The primary objective of this sole source procurement is to standardize airport security screening equipment with DetectaChem's TSA ECP Test Kits based on demonstrated improvements in detection rates, reduced false alarms, faster processing times, and enhanced operational efficiency. The TSA has determined that these kits are the only acceptable solution due to their superior performance characteristics and the fact that they have already undergone extensive evaluation and deployment nationwide. The agency justifies the sole source approach by stating that attempting to deviate from DetectaChem would require substantial duplication of resources across multiple federal agencies in terms of time, money, and personnel. The kits have received approval from the Occupational Safety, Health, and Environment agency and comply with the National Environmental Policy Act, with no significant impact on public health or safety. Given the sole source nature of this procurement, participation is limited to DetectaChem as the exclusive manufacturer and supplier of the required test kits.
