About Chester Supply, LLC
Chester Supply, LLC, a small disadvantaged business and Asian-Pacific American-owned limited liability company headquartered in Manchester, Missouri (with a second location in Ballwin, Missouri), supplies electrical components, industrial equipment, and specialized military-grade parts to federal agencies primarily as a prime contractor under total small business set-asides. The vendor competes almost exclusively within set-aside vehicles, reflecting its SBA certification posture across the federal footprint.
Chester Supply's customer concentration is heavily weighted toward a single vehicle: the GSA Federal Acquisition Service accounts for 1,999 of 2,287 total awards (87% of award count) and $21.8 million of $28.8 million combined potential value (76% of dollars). The Defense Logistics Agency Land and Maritime division represents the second-largest customer by both volume (172 awards) and value ($2.6 million combined potential value), followed by Naval Sea Systems Command ($2.5 million across five awards), the Department of Energy Western Area Power Administration ($180 thousand), and Materiel Command Joint Munitions Command ($296 thousand). The gap between award volume and dollar concentration signals that GSA awards tend to be smaller, individual purchase orders, while DLA Land and Maritime and Navy awards carry larger line values.
Chester Supply's capability footprint is dominated by purchase orders and delivery orders for discrete electrical and industrial components. Representative work includes a $1.308 million total small business set-aside for an isolation transformer delivered to Puget Sound Naval Shipyard (DLA Land and Maritime, June 2024); a $76.092 million total small business set-aside for computer subassemblies (DLA Land and Maritime, September 2025); an $25.303 million total small business set-aside for lighting system components for Yosemite National Park (GSA Pacific West Region, August 2025); and recurring orders for circuit breakers, motor starters, relays, connectors, switches, filters, and related electrical equipment in the hundreds to tens of thousands of dollar range. The vendor also holds a single-award indefinite-delivery contract with DLA Land and Maritime valued at $250 thousand (awarded February 2026, completion February 2027) for specialized connector products. GSA work spans office supplies, electrical equipment, tools, and miscellaneous commercial items, each issued as individual purchase orders under the Multiple Award Schedule or governmentwide small business set-asides.
Activity trajectory shows sharp contraction. Chester Supply received 1,772 awards in 2023 (the baseline year in the source), fell to 261 in 2022, then collapsed to 23 awards in 2024, 53 in 2025, and only 13 in 2026 through April. Combined potential value tracks the same decline, dropping from $28.8 million peak (concentrated in 2023) to current run-rate levels reflecting dozens of micro-orders under $10 thousand each. The vendor's NAICS concentration is extreme: 1,998 of 2,287 awards (87%) fall under NAICS 332999 (Saw Blade and Handtool Manufacturing), though the actual work performed spans electrical components and equipment — a classification mismatch that likely reflects GSA schedule coding rather than core capability. Top PSC codes align more accurately: Sets, Kits, and Outfits of Hand Tools (1,997 awards), Circuit Breakers (34), Connectors (28), and Electrical Hardware (25).
Chester Supply operates exclusively as a prime contractor; the source reports zero subcontract activity. The vendor holds position on the GSA Multiple Award Schedule (with 22 task orders recorded) and multiple DLA Land and Maritime indefinite-delivery contracts, though most work is awarded as individual purchase orders rather than task orders against standing vehicles. No recompete cliff or material future exposure is evident in the source; the dramatic drop in award volume from 2023 to 2026 suggests either market contraction, loss of GSA schedule placement, or reduced ordering velocity from standing customers rather than completion of large multi-year contracts facing recompete.
