About John Chadwick Corporation
John Chadwick Corporation, doing business as Chadwick John Corp, manufactures precision measurement devices and laboratory equipment for the Department of Defense and Defense Logistics Agency as a prime contractor on purchase orders, competing predominantly in full-and-open procurements without set-aside designation, though Total Small Business awards recur across the footprint. The company is a small business for-profit manufacturer based in Monrovia, California, established in 2001, with primary NAICS codes in Analytical Laboratory Instrument Manufacturing (44 awards) and Optical Instrument and Lens Manufacturing (39 awards), and primary PSC concentration in Optical Instruments, Test Equipment, Components and Accessories (60 awards) and Laboratory Equipment and Supplies (22 awards).
John Chadwick's customer base remains concentrated within Navy and Army commands. The top five customer entities by award count account for 49% of recent awards, led by Defense Logistics Agency Land and Maritime (19 awards, $14 thousand combined potential value) and Naval Sea Systems Command (17 awards, $339 thousand combined potential value), with Naval Supply Systems Command (14 awards, $1.7 million combined potential value) anchoring the dollar ranking. The dollar concentration skews toward Naval Supply Systems Command, which dominates the top-five potential-value breakdown with $1.7 million across fourteen awards; by contrast, Land and Maritime places many small awards. Representative work includes a $127,360 Naval Supply Systems Command purchase order for optical micrometers awarded October 30, 2025; a $46,214 Total Small Business purchase order from Naval Sea Systems Command for 750 units of Microset Replication Compound and 38 units of Microset Nozzle Packs awarded September 7, 2023; and a $25,200 Total Small Business purchase order from Department of Defense Aviation for impression inspection services awarded December 29, 2025.
John Chadwick maintains task-order positions on the GSA Multiple Award Schedule (38 task orders, $170 thousand combined potential value) and two smaller vehicles: a Basic Ordering Agreement with Defense Logistics Agency and an Indefinite Delivery Contract (3 task orders each, the latter valued at $221 thousand combined potential value). The vendor's activity pattern shows recent acceleration — one award in 2024 climbing to fifteen in 2025 — but the combined potential value across all 149 awards remains modest at $3.3 million, with obligated dollars reaching $4.1 million across the lifetime portfolio. Performance locations for representative awards split between the contractor's Monrovia, California facility and customer sites including Portsmouth, Virginia for Naval Sea Systems Command work. The vendor operates as a pure prime manufacturer with no subcontract footprint visible in the award data, focusing on low-to-mid-value specialized equipment production for naval maintenance, aviation support, and medical supply chain operations.
