NAICS Code for Research and Development

Federal R&D contracting is a specialized corner of government contracting with its own NAICS structure, size standard quirks, and competition dynamics. DoD (through labs like AFRL, ONR, ARL), NIH, NASA, NSF, and DoE collectively contract tens of billions in R&D services annually. Picking the right NAICS affects which labs and agencies' contracts find you in their searches.

Primary NAICS codes for R&D

541715: Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) ($28M size standard, up to 1,000 employees for some sub-categories) The current primary NAICS for most physical, engineering, and life sciences R&D work. DoD, NASA, NIH, NSF, and DoE all contract through this code. Sub-categories exist (aircraft, space vehicles, guided missiles, etc.) with employee-based size standards up to 1,500.

541713: Research and Development in Nanotechnology (1,000 employees) For nanotechnology-specific R&D. Narrower competition pool, NSF and DoE concentrated.

541714: Research and Development in Biotechnology (except Nanobiotechnology) (1,000 employees) For biotech R&D. NIH, DARPA, BARDA contract heavily here.

541712: Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) (varies) Historical R&D NAICS retained in many agency contracting systems for continuity with pre-2017 contracts. Some agencies still use this code by default even though 541715 is the current standard.

541720: Research and Development in the Social Sciences and Humanities ($25M) For applied social science research, policy evaluation, program assessment, educational research. Often used for DOL, ED, and HHS program evaluation contracts.

Secondary NAICS codes to consider

541330: Engineering Services ($25.5M, up to $47M) For R&D firms with significant engineering design practice.

541512: Computer Systems Design Services ($34M) For R&D firms doing software-heavy research, AI/ML research, cybersecurity R&D.

541990: All Other Professional, Scientific, and Technical Services ($17M) Catch-all for specialized research services.

611310: Colleges, Universities, and Professional Schools ($34M) For university-affiliated research organizations or R&D firms with significant educational activities.

Which code should be your primary

The central question for R&D firms is employee-based vs revenue-based size standards.

Revenue-based primary (541715): Most R&D firms land here. $28M revenue ceiling with some sub-categories higher. Standard application.

Employee-based primary (541713, 541714, or 541715 sub-categories): Firms that are labor-heavy relative to revenue (common in R&D) sometimes benefit from employee-based size standards. At 1,000 employees with modest per-employee revenue, you may stay small longer under employee-count rules.

The sub-category designation matters. 541715 has several sub-categories with different size standards up to 1,500 employees for aerospace and defense R&D. If a significant portion of your work fits a specific sub-category, that sub-category's size standard applies to your classification.

541712 vs 541715: If an agency still references 541712 in their solicitation, use 541712. Most agencies have migrated to 541715. When competing on a 541712 solicitation, make sure your SAM profile shows 541712 registration, not just 541715 — they're treated as distinct codes in contracting searches even though they cover largely the same ground.

Size standard considerations

R&D is unique in federal contracting because many NAICS use employee-based rather than revenue-based size standards. This reflects the labor-intensive nature of research work. If your firm is lean (high revenue per employee), revenue-based standards may give more runway. If your firm is labor-heavy (lots of PhDs and research staff at modest per-employee revenue), employee-based standards may extend your small-business window.

Some 541715 sub-categories have specific size standards tied to contract vehicle or work type. Read the solicitation carefully — the assigned NAICS determines which size standard applies for that specific opportunity.

Federal demand snapshot

DoD labs (AFRL, ARL, NRL, ONR) are the largest federal R&D buyers. DARPA drives high-profile breakthrough research contracts. Service branches procure R&D across materials, AI, autonomous systems, directed energy, hypersonics.

NIH contracts medical research through 541715 life sciences sub-categories and 541714 for biotech.

NASA procures engineering R&D through 541715 with specific aerospace sub-categories.

DoE national labs (ORNL, LANL, SNL, etc.) contract significant R&D volume, though much is concentrated in laboratory-operating M&O contracts at a different NAICS.

NSF awards fundamental research grants and contracts through 541715 and specialty codes.

8(a) firms hold a meaningful share of R&D contracts, particularly at smaller DoD labs and HHS research contracts. SDVOSB set-asides in R&D are less common than in services but do occur at DoD medical research and VA-affiliated research programs.
