TERMINAL JUNCTION BLOCK,SECTIONAL

What the government is buying
The Navy is soliciting offers for terminal junction blocks, sectional—a type of electrical connector hardware used to organize and distribute wiring in military systems. Terminal junction blocks are foundational components in electrical assemblies, providing secure connection points for multiple circuits while allowing for easier troubleshooting and maintenance. The "sectional" designation indicates these are modular units that can be combined or arranged in segments to fit specific space and configuration requirements.
This requirement falls under NAICS 335931 (Current-Carrying Wiring Device Manufacturing), which covers manufacturers of electrical wiring devices including terminals, connectors, and similar components. The classification code 5940 (Lugs, Terminals, and Terminal Strips) further confirms this is a direct procurement of physical hardware rather than assembly services or design work. These parts typically support naval vessel maintenance, aircraft electrical systems, or shore-based infrastructure—see the solicitation for precise end-use application.

Who can bid
This is a full and open competition with no small business set-aside, meaning any responsible offeror—large or small—can submit a bid. Manufacturers registered under NAICS 335931 and distributors capable of meeting original equipment manufacturer (OEM) specifications are eligible.
Small businesses in this NAICS should note the size standard: see the solicitation or SBA.gov for the applicable employee-based threshold. Because this is open competition, you will compete directly against established defense contractors and possibly the original component manufacturer. Past performance delivering to NAVSUP WSS or similar quality-driven military customers will strengthen your position.
If you hold SAM registration and have the required CAGE code, you are technically qualified to bid. However, success typically requires familiarity with MIL-spec compliance, traceability documentation, and Defense Logistics Agency (DLA) acceptance criteria.
How to put together a competitive bid
For open-competition electrical hardware solicitations, focus on these specifics:
Technical compliance: Obtain the exact specification from the solicitation—likely a military specification (MIL-PRF, MIL-DTL, or SAE/ANSI equivalent). NAVSUP WSS purchases require strict adherence to dimensional, material, and performance standards. Do not assume commercial equivalents will pass first article inspection without prior approval.
Quality documentation: Prepare your quality management system credentials. ISO 9001 or AS9100 certification is often expected; see the solicitation for any mandated QMS standard. Document your lot traceability, material certification, and test report capabilities.
Delivery performance: Analyze your production lead time against the contract delivery schedule. NAVSUP WSS Philadelphia emphasizes on-time delivery for fleet readiness. Price aggressively but sustainably—underbidding to win then failing to deliver damages past performance ratings.
Packaging and marking: MIL-STD-129 and MIL-STD-130 marking requirements apply to most NAVSUP hardware. Confirm if this solicitation requires RFID or unique item identification (IUID).
Next steps
Read the full solicitation on SAM.gov using solicitation number N00383-27-Q-TA18. Download the specification, statement of work, and any drawings or first article test requirements. Note the response deadline of November 20, 2026 at 4:30 PM Eastern Time—late submissions are not accepted. Ensure your SAM registration is active and your entity profile reflects NAICS 335931. If technical specifications are beyond your current capability, consider teaming with a qualified manufacturer or requesting the solicitation's small business advocate for clarification.
