Cross-References.Show more

NAICS 325311 – Nitrogenous Fertilizer Manufacturing encompasses the production of synthetic nitrogen-based fertilizers, including ammonium nitrate, urea, ammonium phosphate, and other compound formulations used to enhance soil fertility and crop yields. This sector involves chemical processes such as the Haber-Bosch synthesis of ammonia, oxidation reactions, and granulation or prilling technologies to produce stable, application-ready products.

NAICS 325311 – Nitrogenous Fertilizer Manufacturing encompasses the production of synthetic nitrogen-based fertilizers, including ammonium nitrate, urea, ammonium phosphate, and other compound formulations used to enhance soil fertility and crop yields. This sector involves chemical processes such as the Haber-Bosch synthesis of ammonia, oxidation reactions, and granulation or prilling technologies to produce stable, application-ready products. While primarily an industrial manufacturing function, government demand arises through agencies managing agricultural research, conservation programs, and land management operations—particularly those supporting federal farms, national forests, and research stations under the USDA and Department of the Interior. Contracts may involve procurement of fertilizers for experimental plots, restoration projects, or compliance with soil health initiatives under the Farm Bill and related environmental stewardship programs. No contractor data is available for this NAICS code, indicating limited or fragmented procurement activity in the federal marketplace. When contracts do occur, they are typically awarded to chemical manufacturers with expertise in agricultural inputs, including large industrial producers and specialized small businesses certified under SBA programs such as 8(a) or HUBZone, particularly those with EPA-compliant production facilities and logistics capabilities for bulk chemical handling. No agency data is available, suggesting procurement is sporadic and decentralized rather than concentrated among a few major buyers. When demand exists, it is most likely driven by the U.S. Department of Agriculture’s Agricultural Research Service, the Forest Service, or the Natural Resources Conservation Service for research, demonstration, or land rehabilitation efforts. The competitive landscape is sparse, with low opportunity density due to the niche nature of government demand. Contractors with established supply chains for agricultural chemicals and experience in federal compliance for hazardous material handling are best positioned to respond to occasional solicitations, particularly those tied to climate-smart agriculture or soil carbon sequestration pilot programs.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 325311 work as a small business.

1,050 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.
