NAICS 324191 – Petroleum Lubricating Oil and Grease Manufacturing covers the production of specialized lubricants, greases, and base oils derived from petroleum refining processes, including mineral-based and synthetic formulations engineered for high-performance applications. These products are critical for maintaining operational readiness in military vehicles, aircraft, marine systems, and heavy equipment, where thermal stability, oxidation resistance, and load-bearing capacity are essential. In government contracting, this NAICS supports sustainment and maintenance operations across defense and logistics chains, ensuring equipment reliability under extreme environmental and operational conditions. The sector bridges industrial manufacturing with mission-critical defense supply chains, requiring strict adherence to military specifications such as MIL-PRF-2104E and MIL-PRF-23699. The leading contractor in this sector is ONEIDA BUSINESS ENTERPRISES, INC., a small business specializing in the formulation, packaging, and distribution of defense-grade lubricants and greases tailored to military standards. The competitive landscape is concentrated among niche manufacturers with certified production capabilities and established quality control systems compliant with DoD procurement requirements. The Department of Defense is the primary buyer, driving demand through maintenance programs for armored vehicles, jet engines, naval propulsion systems, and field-deployed machinery. Procurement is tied to readiness cycles, depot-level overhauls, and forward-deployed logistics support, with emphasis on supply chain resilience and long-term storage stability. The market is characterized by high barriers to entry due to stringent specification compliance, certification requirements, and limited qualified suppliers. Opportunities exist for small businesses with expertise in specialty lubricant blending, military specification testing, and just-in-time logistics support. Demand remains steady as modernization efforts and extended equipment service life increase reliance on high-performance lubrication systems.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 324191 work as a small business.

900 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.
