John H Carter Co Inc.

John H Carter Co Inc., a Baton Rouge, Louisiana-based supplier of specialized industrial equipment and aerospace components, operates as a prime contractor (61% of recent awards) and subcontractor on federal procurements for valve, regulator, pump, and control system hardware, competing predominantly under full and open competition rather than set-asides. The company is an undesignated for-profit entity with a subsidiary, Controlworx LLC, and has maintained a federal contracting presence since 2006.

John H Carter Co Inc.'s customer footprint centers almost entirely on NASA's Stennis Space Center operations through the agency's Shared Services Center. Twelve prime purchase orders valued at $1.2 million in combined potential value flow from NASA SSC, representing 100% of the top-customer ranking by both award count and potential value. The remaining seven awards across the Department of Energy Office of Cyber Security, the Department of the Navy Naval Sea Systems Command, the Department of the Army Corps of Engineers Engineering District New Orleans, and NASA Marshall Space Flight Center account for less than $100 thousand combined. This concentration reflects John H Carter Co Inc.'s role as a specialized supplier for Stennis Space Center's A1 Test Stand and associated rocket engine testing infrastructure, where the vendor provides TESCOM pressure reducing regulators, Anderson Greenwood relief valves, HPIW auxiliary supply pump packages, and related high-precision control system components essential to SLS program support. Representative prime awards include a $239,667 firm fixed-price purchase order (September 2025) for delivery and installation of a Goulds 3409S split-case auxiliary supply pump package with 600 horsepower motor; a $203,300 purchase order (June 2023) for TESCOM valves under sole-source procurement; and a $153,249 purchase order (July 2023) for approximately forty valves and repair kits. Most recent awards occurred in June and April 2026 for TESCOM components and RS25 TESCOM regulators respectively.

Activity has remained episodic but consistent — one award in 2007, then dormancy until four awards in 2023, ramping to seven in 2025 and five through June 2026. Two awards totaling $240 thousand face ultimate completion within the next twenty-four months. On the subcontractor side, John H Carter Co Inc. delivers specialized industrial equipment under Fluor Federal Petroleum Operations LLC's Strategic Petroleum Reserve facilities management and operation contract, supplying gate valves, pump assemblies, actuators, and ball valve assemblies since 2024. The vendor also provided umbilical tubing fittings and ISS fittings to Syncom Space Services LLC on a cost-plus-incentive-fee IDIQ. John H Carter Co Inc.'s capability profile is narrowly defined by its specialized manufacturing and supply expertise in pressure control, flow regulation, and industrial pumping equipment for federal aerospace and energy infrastructure.
