This U.S. industry comprises establishments primarily engaged in (1) manufacturing phosphatic fertilizer materials or (2) manufacturing phosphatic materials and mixing with other ingredients into fertilizers. Cross-References.Show more

NAICS 325312 – Phosphatic Fertilizer Manufacturing covers the production of inorganic phosphorus-based fertilizers, including superphosphates, triple superphosphate, ammonium phosphates, and other compound fertilizers derived from phosphate rock and chemical processing. This sector supports agricultural and land management programs that require nutrient-rich soil amendments, particularly in federal land restoration, USDA conservation initiatives, and research plots managed by agencies like the Forest Service and Agricultural Research Service.

NAICS 325312 – Phosphatic Fertilizer Manufacturing covers the production of inorganic phosphorus-based fertilizers, including superphosphates, triple superphosphate, ammonium phosphates, and other compound fertilizers derived from phosphate rock and chemical processing. This sector supports agricultural and land management programs that require nutrient-rich soil amendments, particularly in federal land restoration, USDA conservation initiatives, and research plots managed by agencies like the Forest Service and Agricultural Research Service. While not a traditional defense or infrastructure category, phosphatic fertilizer manufacturing plays a critical role in sustaining federal land use, environmental remediation, and experimental agriculture programs that rely on controlled nutrient application. The production process involves precise chemical synthesis, acidulation, granulation, and quality control to meet USDA and EPA standards for agricultural inputs. No contractor data is available for this NAICS code, indicating limited or no direct federal procurement activity tied to prime contractors specializing exclusively in phosphatic fertilizer manufacturing. The sector is likely served indirectly through agricultural supply vendors or environmental services firms that source fertilizers as part of broader land management contracts rather than through direct manufacturing awards. No agency data is available, suggesting that purchases of phosphatic fertilizers are not centralized or formally tracked as discrete procurement line items. Demand likely arises from decentralized programs within the USDA, DOI, and EPA related to soil health, erosion control, and research station maintenance. The competitive landscape is sparse in the federal contracting space, with opportunities concentrated among small businesses supplying specialty fertilizers under micro-purchase thresholds or as part of bundled environmental services contracts. Procurement trends indicate a growing preference for sustainable, low-impact nutrient formulations, creating niche openings for firms with expertise in controlled-release phosphates or environmentally compliant production methods.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 325312 work as a small business.

1,350 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.
