The Department of Homeland Security, specifically the Transportation Security Administration (TSA), intends to modify an existing contract for Enhanced Metal Detectors (EMDs) using other than full and open competition. This modification aims to sustain the safety and contingency stock inventory of EMDs, which are critical for maintaining security protocols at transportation facilities. The TSA plans to award a sole-source modification to CEIA U.S.A, LTD, located in Hudson, Ohio, under the authority of FAR 6.302-1. Interested parties may express their interest or capability to respond to this requirement within 15 days of the notice, and inquiries should be directed to Jacqueline Thring at jacqueline.thring@tsa.dhs.gov.
