City Chemical LLC

City Chemical LLC, a woman-owned small business manufacturer of inorganic chemicals and reagents based in West Haven, Connecticut, operates as a prime contractor supplying specialized nuclear water chemicals and laboratory reagents to the Department of the Navy under total small business set-aside contracts and blanket purchase agreements.

The vendor's footprint is extraordinarily concentrated: the Naval Supply Systems Command accounts for 426 of 514 total awards (92% of volume) and $61.5 million of the $63.1 million combined potential value across all federal work. This concentration reflects City Chemical's strategic role as a recurring supplier of commodities critical to Navy nuclear water programs and fleet readiness. The Department of the Navy broadly has placed 17 additional awards totaling $497 thousand, while the Defense Logistics Agency Aviation has issued 23 awards valued at $118 thousand. Two other customer agencies—the Department of Homeland Security Transportation Security Administration and Naval Sea Systems Command—represent marginal activity. The top-customer rankings align: NAVSUP dominates both volume and dollars, with no meaningful divergence.

City Chemical's capability portfolio centers on Federal Supply Class 6810 nuclear water chemicals delivered through two large BPAs established March 31, 2022. The first BPA (N0010422AZ601), valued at $27 million through March 31, 2027, has generated 72 task orders totaling $2.7 million in combined potential value. The second BPA (N0010417AAF01), valued at $13 million through the same expiration, has produced 54 task orders worth $3.7 million. Representative task-order work includes a $286,783.20 silver nitrate call (March 12, 2026), a $220,340.10 ammonium hydroxide call (December 4, 2025), a $187,947 hydrazine dihydrochloride call (March 5, 2026), a $126,555 hydrazine reagent purchase order (April 29, 2024), and a $263,970 sodium phosphate definitive contract (June 25, 2025). Additional product lines ordered under these BPAs include morpholine, nitric acid, potassium iodide, sodium nitrate, chloride indicators, mercuric nitrate, zinc oxide compounds, and buffer kits, with individual call values ranging from approximately $6,000 to $250,000. The vendor also holds five additional smaller BPAs under NAVIS, reflecting a diverse BPA portfolio structured to distribute nuclear water chemical sourcing across multiple vehicle numbers while maintaining total small business set-aside status.

Two TSA purchase orders for chemical laboratory supplies (July 5, 2024 and June 5, 2023, each under $52,000) represent the only non-set-aside work in the prime portfolio and the only activity outside Navy nuclear water programs. City Chemical subcontracts minimally—the source records only one sub-award, a July 2025 task order under General Dynamics Information Technology for threat mitigation, engineering, and image support services on the SST 4.0 IDIQ, representing negligible sub engagement relative to the prime footprint.

Award volume has remained stable year over year (19 to 25 awards annually from 2022 through 2025, with only 5 awards recorded through March 2026), and recompete exposure in the next twenty-four months is minimal—only one award with a $244 thousand ceiling faces completion within that window. The two primary NAVSUP BPAs, which anchor the customer relationship and drive the bulk of ordering, run through March 31, 2027, providing visibility through that date. City Chemical's registration in SAM.gov since August 2001 and its narrow, deeply rooted supplier relationship with NAVSUP indicate a specialized, stable footprint with minimal product and customer diversification.
