NAICS 326140 – Polystyrene Foam Product Manufacturing encompasses the production of expanded and extruded polystyrene foam products used for thermal insulation, cushioning, packaging, and structural core applications in government infrastructure and defense systems. This manufacturing sector transforms polystyrene resin into rigid foam boards, molded shapes, and custom-engineered components that meet stringent federal specifications for fire resistance, buoyancy, and dimensional stability. Products in this category are critical to military housing units, naval vessel insulation, temporary field facilities, and protective packaging for sensitive equipment. The industry operates within a highly regulated supply chain, requiring compliance with ASTM, MIL-SPEC, and EPA standards for volatile organic compound emissions and recyclability. No contractor data is available for this NAICS code, indicating limited visibility into prime contractors or small business participation in federal procurement. The competitive landscape may be fragmented among regional manufacturers and specialty fabricators, with potential involvement from large industrial suppliers offering integrated material solutions. No agency data is available, suggesting procurement activity is either decentralized, sporadic, or embedded within broader construction, logistics, or defense equipment contracts rather than tracked as a standalone line item. Demand likely stems from the Department of Defense, General Services Administration, and U.S. Army Corps of Engineers for infrastructure, temporary shelters, and transport packaging. The market context reflects low opportunity density for new entrants due to the specialized nature of foam manufacturing and limited direct federal solicitation. Opportunities exist for contractors with certified production capabilities, particularly those capable of meeting military-grade performance criteria and offering just-in-time delivery for remote or expeditionary operations. Long-term trends point toward increased emphasis on sustainable materials and reduced lifecycle environmental impact, creating potential for innovation in recycled-content foams and low-emission formulations.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 326140 work as a small business.

1,000 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.
