City Chemical LLC

City Chemical LLC, a woman-owned small business manufacturer based in West Haven, Connecticut, supplies specialized inorganic chemicals and reagents to the federal government as a prime contractor, overwhelmingly through the Naval Supply Systems Command's blanket purchase agreements.

City Chemical operates as a for-profit corporation with 517 total federal awards on record spanning from 1998 through August 2026. The vendor competes entirely under total small business set-asides across its federal footprint — all BPA calls and purchase orders carry the total small business set-aside designation. The company's NAICS profile centers on all-other basic organic chemical manufacturing (201 awards) and analytical laboratory instrument manufacturing (116 awards), with supporting activity in basic inorganic chemical manufacturing (92 awards). PSC coding clusters heavily on chemicals (476 awards), with minor exposure to chemical analysis instruments and gas generating systems.

Customer concentration is extreme and by design. Naval Supply Systems Command accounts for 428 of 517 awards (83%) and $61.6 million of $63.2 million combined potential value (97%). The next-largest customer, Defense Logistics Agency Aviation, holds 23 awards worth $118 thousand — roughly 500 times smaller. The Transportation Security Administration, Department of the Navy proper, and Naval Sea Systems Command together account for fewer than 25 awards combined. This concentration reflects City Chemical's core business model: recurring supply of nuclear water chemicals and fleet-readiness materials to the Navy's logistics backbone.

City Chemical holds two primary BPAs with Naval Supply Systems Command, both awarded March 31, 2022, with performance extending through March 31, 2027. The first BPA (N0010422AZ601) carries a $27 million ceiling and has generated 56 task orders; the second (N0010417AAF01) carries a $13 million ceiling and has generated 72 task orders, for combined recent activity of $6.5 million across 128 calls. Three additional smaller BPAs (N0010414A7000, N0010417AAM01, and a third vehicle) account for 48 additional task orders. All BPA calls employ firm fixed-price pricing and are performed at City Chemical's West Haven facility. Representative product lines ordered under these vehicles include ammonium hydroxide ($220,340 in December 2025), sodium phosphate tribasic ($220,300 in March 2024), morpholine ($85,743 in July 2025), mercuric nitrate, chloride indicators, silver nitrate, hydrazine compounds, potassium iodide, nitric acid, sodium nitrate, zinc oxide, and buffer kits. Individual task-order ceilings range from approximately $6,000 to $287,000.

Beyond the Navy's dominant footprint, City Chemical has taken spot work from the Transportation Security Administration for chemical laboratory procurement — two orders in 2023 ($23,810 and $51,677) and one in 2024 ($51,677) for laboratory chemicals — and sporadic orders from Defense Logistics Agency Aviation for aircraft maintenance chemicals. The vendor subcontracts minimally; one sub-award on record is a $100+ thousand task under General Dynamics Information Technology for threat-mitigation and engineering support, suggesting occasional pass-through supply work on larger defense prime contracts.

Activity has remained steady across the past five years, averaging 18–25 awards per year, with 2026 showing only 8 awards so far (partial-year data through August). The recompete cliff for the next 24 months is modest — only two awards totaling $264 thousand face completion before October 2028, indicating minimal near-term recompete pressure on the core BPA portfolio, which does not expire until March 2027. City Chemical has maintained continuous SAM.gov registration since August 2001, signaling long-term federal supplier status. The vendor's tight coupling to Naval Supply Systems Command and total-small-business set-aside posture creates a narrow competitive moat against full-and-open competition but leaves little room for customer diversification or upmarket expansion into larger prime vehicles.
