Competing in this code
80,822 actions and 1,546 IDVs means the transaction cost of a proposal has to be near zero for this code to be profitable. Vendors who succeed sell through catalog vehicles, GSA schedules, and DLA long-term contracts, then let the orders arrive. Chasing individual solicitations at $6,600 a piece does not cover the bid and proposal cost. The two credentials that open the higher-value slice are GSA Approved Products List listing for security containers and locks, and Buy American or Trade Agreements Act compliant domestic sourcing, which a large share of commercial hardware cannot document.
Frequently Asked
NAICS 332510 questions, answered.
What is the SBA size standard for NAICS 332510?
SBA sets it at 750 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 332510 solicitations and eligible for the set-asides in this code.
Which agencies buy locks and builders hardware under NAICS 332510?
FY2025 obligations: DoD ($478 million), GSA ($34 million), State ($6 million), DHS ($4 million), Interior ($3 million). DoD is nearly 90 percent, split between installation facility maintenance and shipboard or vehicle hardware.
Is federal hardware business worth pursuing at $6,600 per award?
Only through catalog vehicles. NAICS 332510 ran 80,822 actions for $537 million in FY2025, so bid and proposal cost per award has to be effectively zero. Vendors who profit here hold a GSA schedule or a DLA long-term contract and receive orders automatically instead of responding to individual solicitations.
What certifications raise the value of a NAICS 332510 registration?
Listing on the GSA Approved Products List for security containers and high-security locks moves you into a smaller, higher-value competitive pool. Documented Buy American or Trade Agreements Act compliant domestic sourcing matters just as much, because a large share of commercial builders hardware cannot substantiate country of origin.
