About this file
This is a Statement of Work (SOW) from the Federal Protective Service (FPS), a division of the Department of Homeland Security (DHS), for the manufacture and delivery of Canine Explosive Scent Kits (CESKs) to support the FPS Explosives Detection Canine Program.
FPS seeks high-fidelity, standardized CESKs containing pure explosives and chemical precursors used in explosives manufacturing. Each Regional CESK contains 14 items including ammonium nitrate, C-4, dynamite, HMX flake, Composition A-5 powder, C-2 sheet explosives, Semtex 1A, smokeless powders, TNT, sodium chlorate, potassium chlorate, black powder, and potassium perchlorate, each packaged in specified quantities (ranging from 1-4 pounds per item) with precise sub-packaging requirements. The Headquarters CESK contains these same items plus an additional 12 items including ammonium nitrate/fuel oil, Emulsion Dyno AP, calcium ammonium nitrate, Cast Booster, Composition B Flake, detonating cords, hexamine, nitromethane, pyrodex, and safety/time fuse. All materials must be packaged in unprinted medical-grade Tyvek breather bags with high-density film, vacuum-sealed in MIL-PRF-8170E metallic shielding bags, and labeled with specific information including manufacturer, UN classification, batch/lot number, Net Explosive Mass, and the FPS contact number. Each kit includes extinction training aids (blank/uncontaminated control samples) to ensure canines do not alert to packaging materials. Deliveries are FOB destination CONUS with the contractor responsible for all shipping costs and DOT compliance. The Government will order a maximum of 28 Regional CESKs and one Headquarters CESK in Ordering Periods 1, 3, and 5, and 29 Regional CESKs in Ordering Periods 2 and 4, with delivery required 30 days after order receipt to specified FPS regional office locations across the United States and Puerto Rico.
The contract is structured as a Firm-Fixed-Price agreement with a base period from October 1, 2026 through September 30, 2027, and four option years extending through September 30, 2031. The contractor must demonstrate at least five years of experience in chemical scent formulation for working dogs and provide three references from government or law enforcement agencies with successful delivery of explosive training aids within the last 36 months. All contractor personnel involved in manufacturing, logistics, and delivery must pass background checks within the last three years, be U.S. Citizens or legally authorized to work with sensitive security materials, and sign a Non-Disclosure Agreement protecting shipping details, destinations, quantities, and proprietary formulations. The Government has 15 business days post-delivery to inspect shipments for quantity, damage, and chemical purity, with the contractor responsible for correction and re-delivery at no additional cost. The contractor assumes all liability for hazardous materials transport until formal Government Acceptance and is solely responsible for fines, cleanup costs, or legal fees resulting from improper packaging or non-compliance with DOT/IATA regulations. Technical Point of Contact is Mr. John J. Hogan at (703) 245-2481 or (202) 567-1689; Contracting Officer's Representative is Ms. Shontay Cokley at 703-639-3755.

Federal Protective Service
Law Enforcement Operations Division
Statement of Work (SOW) for Canine Explosive Scent Kits (CESK)
April 13, 2026
Department of Homeland Security (DHS)
Federal Protective Service (FPS) Statement of Work (SOW)
1.0 STATEMENT OF WORK
1.1 Background
The Federal Protective Service (FPS) uses its security expertise and law enforcement authority to protect federal government facilities and safeguard the millions of employees and visitors who pass through them every day. With a presence in every state and territory, the FPS mission is to prevent, protect, respond to, and recover from acts of terrorism and other hazards threatening the federal government’s essential services, ensuring the continuity of the U.S.
Government.
The FPS Canine Operations Branch's Explosives Detection Canine Program supports the mission of FPS through utilization of law enforcement canine teams that travel to Federal facilities and aid in security efforts. The Canine Operations Branch provides Explosives Detection Canine Teams (EDCT) which render federal properties safe and secure for federal employees, officials, and visitors by providing a strong visible and psychological deterrence against criminal and terrorist acts. The EDCTs conduct searches and sweeps for explosive components and respond to threats to federally owned, leased, or secured property.
1.2 Scope
The objective of this contract is to provide the FPS with high-fidelity, standardized Canine Explosive Scent Kits (CESKs). These CESK are critical for the initial imprint, training, maintenance, and operational certification of EDCTs. The scope encompasses the manufacture, specialized packaging, and multi-year delivery of regional, and headquarter CESKs, including, specific “extinction” training aids to ensure canine accuracy.
FPS intends to acquire multiple CESKs for the FPS Explosives Detection Canine Program through a Purchase Order.
1.3 Specific Requirements:
1.3.1 CESK Requirements
Each CESK and its individual component CETA shall be made, handled, packaged, stored, and transported in a manner to protect against spillage, cross contamination, degradation, and safe handling.
The Government reserves the right to have each CETA tested for purity. The CESKs shall contain pure explosives and chemical precursors used in the making of explosives.
The CESKs shall not contain pseudo-explosives, non-detonable training aids, or inert products.

1.4 Packaging of Canine Explosive Training Aids
1.4.1 Each CETA item shall be packaged in an unprinted, medical-grade, breathable
Tyvek (Type 1059B or 1073B) pouch and one side made of .003” Precision Clean high-density film. An ionizing bar shall be used to reduce static and allow substance to drop more freely inside the bag when filling. An A-B-C sealer machine or similar device will be used to ensure seals are straight and tight.
1.4.2 Each breather bag will have a double heat seal to provide extra security and help prevent blow outs or spillage during transportation and training use.
1.4.3 The contractor shall ensure the heat sealer is set to the correct temperature to ensure a “fusion seal” rather than a “tack seal.”
1.4.4 The secondary shielding bag/pouch must provide a minimum thickness of
0.004 inches and function to prevent electrostatic discharge and vapor barrier to contain volatile organic compounds (VOCs). This secondary pouch shall be vacuum-sealed within a MIL-PRF-8170E Type I Opaque Metallic Shielding Bag.
1.4.5 To ensure scent purity, the exterior of the secondary bag must be decontaminated with an alcohol-based solvent after sealing to remove transfer odors.
1.4.6 Each bag/pouch shall be labeled with the explosive component contained inside, product manufacturer, UN classification, Batch/Lot Number, Net Explosive Mass (N.E.M), the Ex-Number (Explosives Approval Number), and a Serialized Number. Labels must include the warning: EXPLOSIVES - DANGEROUS Handle Carefully for high and low explosives, or FLAMMABLE SOLID – DANGEROUS Handle Carefully for oxidizers. If found, contact the Federal Protective Service 1-800-437-7411 shall be on each bag/pouch containing the material.
