TC Chemicals, LLC

TC Chemicals, LLC, a self-certified small disadvantaged business headquartered in Pearland, Texas, manufactures and supplies fuel system icing inhibitor (FSII) and diesel fuel additive (LIA) chemicals to the Department of Defense as a prime contractor under a single-award indefinite delivery vehicle with the Defense Logistics Agency Energy. The company operates from a production facility in Brookside Village, Texas, and competes entirely on full-and-open delivery orders without set-aside designations across its current IDV vehicle (though the underlying IDV itself carries a partial small business set-aside).

TC Chemicals' entire federal footprint centers on one customer and one product line: FSII and diesel fuel additives for military fuel system operability in cold weather environments. DLA Energy accounts for all 822 awards and $89.2 million in combined potential value tracked in the source. The company has executed sustained recurring delivery orders under its current single-award IDV (SPE60222D0751, awarded December 23, 2024, with an $8.618 million ceiling through March 31, 2027) since that contract's establishment. The prior IDV, which ran through July 2024 with a $27 million ceiling, carried 532 delivery orders from November 2021 forward. The current IDV has generated 12 delivery orders to date (as of early March 2026), ranging from $26,085.97 to $616,036.17, with most issued under partial small business set-aside and recent orders (August 2025 forward) issued without set-aside. Representative recent awards include a $616,036.17 delivery order on January 5, 2026; a $66,397.11 delivery order on December 15, 2025; and a $39,024.50 delivery order on January 28, 2026 — all fixed-price with economic price adjustment and all for FSII supply to DLA Energy.

Activity over the past five years shows a sharp decline: 174 awards in 2024, 179 in 2023, 174 in 2022, then only 10 in 2025 and 4 through March 2026. This trajectory reflects the transition from the prior $27 million IDV (which expired July 2024 after generating hundreds of small delivery orders monthly) to the new $8.6 million IDV awarded December 23, 2024. The source data window captures the gap between vehicle recompetes. DLA Energy has centralized ordering under the two active IDVs: the legacy SPE60219D0759 (228 task orders, $8.6 million combined value) and SPE60219D0760 (46 task orders, $2.1 million combined value) remain in the portfolio alongside the current primary vehicle SPE60222D0751. All delivery orders are fixed-price with economic price adjustment. Place of performance spans the Continental United States, Europe, the Middle East, and Guam; work is performed at the Brookside Village production facility. TC Chemicals delivers approximately 4.8 million gallons of FSII and 112,500 gallons of LIA annually to support global military fuel system requirements.

TC Chemicals has no subcontractor footprint, no parent contract vehicles outside DLA Energy, and no teaming arrangements in the source data. The vendor is 100% dependent on DLA Energy and 100% focused on a single commodity class (fuel system additives under PSC Miscellaneous Chemical Specialties and NAICS 325998 Petroleum Refineries). The vendor competes on full-and-open delivery orders once a vehicle is awarded; the vehicle itself carries the small disadvantaged business set-aside designation, but individual orders do not. All obligations are to a single federal agency, making TC Chemicals a highly specialized, single-customer defense supplier with no diversification or subcontracting reach into the broader federal contractor ecosystem.
