The Transportation Security Administration needs to procure Potassium Chlorate, Potassium Perchlorate, and Ammonium Nitrate for its National Explosives Detection Canine Team Program. Market research conducted in February 2026 identified two potential suppliers, City Chemical and Thermo Fisher Scientific. City Chemical confirmed it can provide the full requirement within the specified timeframe, while Thermo Fisher Scientific could not supply one of the chemicals. As a result, TSA determined that only City Chemical can meet the precise product, quantity, and timeline needed. No budget amounts or performance location were specified.
