About the company
Kastalon Inc., doing business as Kastalon Polyurethane Products, manufactures custom polyurethane components for military and defense logistics applications as a prime contractor operating on full-and-open and total small business set-aside purchase orders and delivery orders from the Defense Logistics Agency. The company is a for-profit Subchapter S Corporation headquartered in Alsip, Illinois, with performance at its facility in Merrionette Park, Illinois. Kastalon competes predominantly under total small business set-asides, which account for roughly half of its recent awards; the other half are full-and-open, non-set-aside delivery orders under its primary IDC relationship with DLA Land and Maritime.
Kastalon's capability portfolio centers on precision-engineered polyurethane pads, assemblies, wheels, chocks, bumpers, hoses, and cable termination chambers for military ground vehicles, maritime systems, and electronic equipment. The company's NAICS profile clusters around aircraft parts manufacturing and miscellaneous elastomers, reflecting the aerospace and defense end-use of its components; primary PSC coding tracks aircraft landing equipment and ground servicing equipment. Representative work includes a $159,795 delivery order from DLA Land and Maritime (April 2022) for terminal pad assemblies under firm fixed-price terms, a $143,500 purchase order from DLA Troop Support Construction and Equipment (April 2022) for 700 wheel-track chocks under total small business set-aside, and a $121,905 purchase order from DLA Aviation (February 2022) for cable termination chambers. Recent work in 2024–2025 includes smaller-value delivery orders ranging from $13,260 to $158,790 for terminal pad assemblies and wheel-track chocks.
Customer concentration is extreme: DLA Land and Maritime accounts for 72 awards (combined potential value $7.6 million) and dominates the portfolio by both volume and dollars. DLA Troop Support Construction and Equipment contributes 31 awards ($836 thousand), with DLA Aviation, Naval Sea Systems Command, and Naval Facilities Engineering Command rounding out the customer set at far lower volumes. These top five customers account for 90% of awards and nearly all potential value. The relationship with DLA is anchored to a single-award Indefinite Delivery Contract (SPE7MX21D0036) valued at $1.9 million running through January 2026, under which Kastalon has issued 26 delivery orders. A second IDC (SPM7M207D7024) with combined potential value $1.1 million and seven task orders is also active, likely with a DLA sub-activity.
Award activity has declined materially: the company received 18 awards in 2022, 13 in 2023, 9 in 2024, and only 5 in 2025, with 2 awards in 2026 through May. Combined potential value across all 145 recent awards stands at $8.8 million, with obligated dollars at $9.3 million. The recompete cliff is minimal—only 2 awards with combined potential value $116 thousand reach ultimate completion within the next twenty-four months, meaning near-term recompete risk is limited but the underlying IDC relationships anchoring the portfolio will require attention as the primary vehicle expires January 2026. Kastalon operates as a 100% prime contractor with no subcontract footprint in the source data, meaning the company does not sub to larger primes and does not pursue teaming arrangements on its own awards.
