NAICS 311221 – Wet Corn Milling and Starch Manufacturing encompasses the industrial processing of corn through wet milling to produce starch, corn syrup, glucose, and other derived products such as dextrose, maltodextrin, and corn oil. This sector supports government supply chains by providing essential food ingredients for military rations, nutrition programs, and institutional feeding operations, including those managed by the Department of Defense and the U.S. Department of Agriculture. The process involves steeping corn in sulfurous acid, separating germ, fiber, and protein fractions, and refining starch through filtration and drying. While primarily a commercial manufacturing activity, federal demand arises when agencies require consistent, high-purity starches for food service contracts, emergency nutrition reserves, or specialized dietary formulations for federal facilities. No contractor data is available for this NAICS code, indicating limited or no direct federal procurement activity tied to wet corn milling and starch manufacturing. There are no identifiable prime contractors or small business vendors with significant award volumes in government contracting databases, suggesting this sector is not a traditional focus of federal acquisition. No agency data is available, implying that while federal agencies may consume end products derived from this industry—such as corn-based sweeteners in meal kits or starches in processed foods—there is no centralized or documented procurement stream specifically targeting the wet milling process itself. The market context reveals low opportunity density for direct government contracting, as most federal demand is satisfied through indirect supply chains via food service distributors or contract manufacturers. Opportunities for contractors are limited to niche roles supporting compliance, logistics, or quality assurance for USDA or DOD food programs, rather than direct manufacturing awards.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 311221 work as a small business.

1,300 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.
