NAICS 423320 – Brick, Stone, and Related Construction Material Merchant Wholesalers encompasses the wholesale distribution of masonry and hardscape materials used in federal infrastructure and facility construction projects. This includes manufactured brick, structural and decorative stone, concrete block, pavers, mortar, and related masonry accessories sold to contractors, public works departments, and federal construction managers. These wholesalers serve as critical supply chain intermediaries, connecting manufacturers with end-users on projects ranging from military base renovations and VA hospital expansions to Corps of Engineers flood control structures and GSA building retrofits. While not directly performing construction, these distributors enable compliance with federal procurement standards for durable, code-compliant building materials and often support Just-in-Time delivery requirements on time-sensitive federal job sites. No contractor data is available to identify top performers in this NAICS code within the government contracting space. The competitive landscape is likely composed of regional and national wholesale distributors, some of which may hold small business certifications, but no dominant primes or specialized federal suppliers are currently identifiable from available award records. No agency data is available to pinpoint primary buyers. However, demand is typically driven by agencies managing physical infrastructure, including the Department of Defense, General Services Administration, Department of Veterans Affairs, and the U.S. Army Corps of Engineers, particularly during capital improvement cycles or disaster recovery efforts requiring durable, long-life masonry components. The market context reflects moderate opportunity density with low barriers to entry for qualified distributors, though success requires familiarity with federal procurement regulations, including FAR compliance, material certification requirements, and delivery timelines. Contractors with established logistics networks and pre-qualified vendor status on GSA schedules or agency-specific blanket purchase agreements are best positioned to capture recurring demand in federal construction supply chains.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 423320 work as a small business.

150 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
