NAICS 562211 – Hazardous Waste Treatment and Disposal encompasses the safe handling, treatment, stabilization, transportation, and final disposal of regulated hazardous wastes, including chemical, biological, and radioactive materials. This sector supports federal compliance with the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), providing critical services such as incineration, chemical neutralization, landfill engineering, and decontamination of contaminated sites. Government contractors in this space deliver specialized engineering solutions for remediation, waste characterization, and regulatory permitting, often working in high-risk environments requiring strict adherence to EPA and DOT protocols. This NAICS is integral to federal environmental stewardship, supporting cleanup missions across military installations, research facilities, and public health infrastructure. Top contractors in this sector include AAECON GENERAL CONTRACTING LLC, CONSULTECH ENVIRONMENTAL LLC, and RE-ENGINEERED BUSINESS SOLUTIONS, INC., representing a mix of small businesses and niche environmental engineering firms with deep expertise in hazardous materials management. These firms typically compete on technical capability, regulatory compliance experience, and rapid response capacity rather than scale, reflecting a market where specialized certifications and field operational proficiency are decisive advantages. The Department of the Interior, Department of Health and Human Services, Department of Defense, and Department of Justice are the primary federal buyers, driven by missions ranging from legacy site remediation at former defense facilities to the safe disposal of pharmaceutical and laboratory wastes from federal research labs and correctional medical programs. Demand is consistently tied to environmental enforcement actions, facility decommissioning cycles, and ongoing compliance obligations. The competitive landscape is characterized by high barriers to entry due to permitting, safety, and logistics requirements, creating concentrated opportunities for firms with proven track records in federal environmental remediation. Contracting trends favor integrated service providers capable of end-to-end waste management, from sampling and analysis to final disposal and documentation, with increasing emphasis on sustainable treatment technologies and real-time monitoring systems.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 562211 work as a small business.

$47.0M
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.
