U. S. Small Business Administration 

Table of Small Business Size Standards 

Matched to 

North American Industry Classification System Codes 

This table lists small business size standards matched to industries described in the North 

American Industry Classification System (NAICS), as modified by the Office of Management and 

Budget effective January 1, 2012. The latest NAICS codes are referred to as NAICS 2012. 

The size standards are for the most part expressed in either millions of dollars (those 

preceded by “$”) or number of employees (those without the “$”). A size standard is the largest 

that a concern can be and still qualify as a small business for Federal Government programs. For 

the most part, size standards are the average annual receipts or the average employment of a firm. 

How to calculate average annual receipts and average employment of a firm can be found in 

13 CFR § 121.104 and 13 CFR § 121.106, respectively. 

SBA also includes the table of size standards in the Small Business Size Regulations, 

13 CFR § 121.201. This table includes size standards that have changed since the last publication of 

13 CFR § 121. 

For more information on these size standards, please visit http://www.sba.gov/size. 

If you have any other questions concerning size standards, contact a Size Specialist at your 

nearest SBA Government Contracting Area Office (list at the end of the table), or contact the Office 

of Size Standards by email at sizestandards@sba.gov or by phone at (202) 205-6618. 

These size standards are effective

1. [Reserved].

2. NAICS code 237990 – Dredging: To be considered small for purposes of Government 

procurement, a firm must perform at least 40 percent of the volume dredged with its own 

equipment or equipment owned by another small dredging concern. 

3. NAICS code 311421 – For purposes of Government procurement for food canning and 

preserving, the standard of 1,000 employees excludes agricultural labor as defined in section 

3306(k) of the Internal Revenue Code, 26 U.S.C. 3306(k). 

4. NAICS code 324110 – To qualify as small for purposes of Government procurement, the 

petroleum refiner, including its affiliates, must be a concern that has either no more than 1,500 

employees or no more than 200,000 barrels per calendar day total Operable Atmospheric 

Crude Oil Distillation capacity. Capacity includes all domestic and foreign affiliates, all owned or 

leased facilities, and all facilities under a processing agreement or an arrangement such as an 

exchange agreement or a throughput. To qualify under the capacity size standard, the firm, 

together with its affiliates, must be primarily engaged in refining crude petroleum into refined 

petroleum products. A firm’s “primary industry” is determined in accordance with 

13 CFR § 121.107.

5. NAICS code 326211 – For Government procurement, a firm is small for bidding on a 

contract for pneumatic tires within Census NAICS Product Classification codes 3262111 and 

3262113, provided that:

a) The value of tires within Census NAICS Product Classification codes 3262113 that it 

manufactured in the United States during the previous calendar year is more than 50 

percent of the value of its total worldwide manufacture, 

b) The value of pneumatic tires within Census Classification codes 30111 and 30112 

comprising its total worldwide manufacture during the preceding calendar year was less 

than 5 percent of the value of all such tires manufactured in the United States during 

that period, and

c) The value of the principal product that it manufactured, produced, or sold worldwide 

during the preceding calendar year is less than 10 percent of the total value of such 

products manufactured or otherwise produced or sold in the United States during that 

period.

6. NAICS Subsectors 333, 334, 335 and 336 – For rebuilding machinery or equipment on a 

factory basis, or equivalent, use the NAICS code for a newly manufactured product. Concerns 

performing major rebuilding or overhaul activities do not necessarily have to meet the criteria 

for being a "manufacturer" although the activities may be classified under a manufacturing 

NAICS code. Ordinary repair services or preservation are not considered rebuilding. 

7. NAICS code 336413 – Contracts for the rebuilding or overhaul of aircraft ground support 

equipment on a contract basis are classified under NAICS code 336413. 

8. NAICS Codes 522110, 522120, 522130, 522190, and 522210 – A financial institution's 

assets are determined by averaging the assets reported on its four quarterly financial 

statements for the preceding year. "Assets" for the purposes of this size standard means the 

assets defined according to the Federal Financial Institutions Examination Council 041 call 

report form for NAICS Codes 522110, 522120, 522190, and 522210 and the National Credit 

Union Administration 5300 call report form for NAICS code 522130.

9. NAICS codes 531110, 531120, 531130, and 531190 – Leasing of building space to the 

Federal Government by Owners: For Government procurement, a size standard of $38.5 million 

in gross receipts applies to the owners of building space leased to the Federal Government. The 

standard does not apply to an agent. 

10. NAICS codes 488510, 531210, 541810, 561510, 561520 and 561920 – As measured by 

total revenues, but excluding funds received in trust for an unaffiliated third party, such as 

bookings or sales subject to commissions. The commissions received are included as revenue.

11. NAICS code 541711 and 541712:

a) "Research and Development" means laboratory or other physical research and 

development. It does not include economic, educational, engineering, operations, 

systems, or other nonphysical research; or computer programming, data processing, 

commercial and/or medical laboratory testing.

b) For research and development contracts requiring the delivery of a manufactured 

product, the appropriate size standard is that of the manufacturing industry.

c) For purposes of the Small Business Innovation Research (SBIR) program only, a different 

definition has been established by law. See § 121.701 of these regulations.

d) Research and Development for guided missiles and space vehicles includes evaluations 

and simulation, and other services requiring thorough knowledge of complete missiles 

and spacecraft.
43

12. NAICS 561210 – Facilities Support Services: 

a) If one or more activities of Facilities Support Services as defined in paragraph (b) (below 

in this footnote) can be identified with a specific industry and that industry accounts for 

50% or more of the value of an entire procurement, then the proper classification of the 

procurement is that of the specific industry, not Facilities Support Services.

b) "Facilities Support Services" requires the performance of three or more separate 

activities in the areas of services or specialty trade contractors industries. If services are 

performed, these service activities must each be in a separate NAICS industry. If the 

procurement requires the use of specialty trade contractors (plumbing, painting, 

plastering, carpentry, etc.), all such specialty trade contractors activities are considered 

a single activity and classified as "Building and Property Specialty Trade Services." Since 

"Building and Property Specialty Trade Services" is only one activity, two additional 

activities of separate NAICS industries are required for a procurement to be classified as 

"Facilities Support Services."

13. NAICS code 238990 – Building and Property Specialty Trade Services: If a procurement 

requires the use of multiple specialty trade contractors (i.e., plumbing, painting, plastering, 

carpentry, etc.), and no specialty trade accounts for 50% or more of the value of the 

procurement, all such specialty trade contractors activities are considered a single activity and 

classified as Building and Property Specialty Trade Services.

14. NAICS 562910 – Environmental Remediation Services:

a) For SBA assistance as a small business concern in the industry of Environmental

Remediation Services, other than for Government procurement, a concern must be 

engaged primarily in furnishing a range of services for the remediation of a 

contaminated environment to an acceptable condition including, but not limited to, 

preliminary assessment, site inspection, testing, remedial investigation, feasibility 

studies, regulatory compliance, remedial design, containment, remedial action, removal 

of contaminated materials, nuclear remediation, storage of contaminated materials and 

security and site closeouts. If one of such activities accounts for 50 percent or more of a 

concern's total revenues, employees, or other related factors, the concern's primary 

industry is that of the particular industry and not the Environmental Remediation 

Services Industry.

b) For purposes of classifying a Government procurement as Environmental Remediation 

Services, the general purpose of the procurement must be to restore or directly support 

the restoration of a contaminated environment. This includes activities such as 

preliminary assessment, site inspection, testing, remedial investigation, feasibility 

studies, regulatory compliance, remedial design, remediation services, containment, 

nuclear remediation, and removal of contaminated materials or security and site

closeouts. The general purpose of the procurement need not necessarily include 
44

remedial actions. Also, the procurement must be composed of activities in three or 

more separate industries with separate NAICS codes or, in some instances (e.g., 

engineering), smaller sub-components of NAICS codes with separate and distinct size 

standards. These activities may include, but are not limited to, separate activities in 

industries such as: Heavy Construction; Special Trade Contractors; Engineering Services; 

Architectural Services; Management Consulting Services; Hazardous and Other Waste 

Collection; Remediation Services; Testing Laboratories; and Research and Development 

in the Physical, Engineering, and Life Sciences. If any activity in the procurement can be 

identified with a separate NAICS code, or component of a code with a separate distinct 

size standard, and that industry accounts for 50 percent or more of the value of the 

entire procurement, then the proper size standard is the one for that particular 

industry, and not the Environmental Remediation Service size standard.

16. NAICS code 611519 – Job Corps Centers. For classifying a Federal procurement, the 

purpose of the solicitation must be for the management and operation of a U.S. Department of 

Labor Job Corps Center. The activities involved include admissions activities, life skills training, 

educational activities, comprehensive career preparation activities, career development 

activities, career transition activities, as well as the management and support functions and 

services needed to operate and maintain the facility. For SBA assistance as a small business 

concern, other than for Federal Government procurements, a concern must be primarily 

engaged in providing the services to operate and maintain Federal Job Corps Centers. 

17. NAICS code 115310 – Support Activities for Forestry – Forest Fire Suppression and Fuels 

Management Services are two components of Support Activities for Forestry. Forest Fire 

Suppression includes establishments which provide services to fight forest fires. These firms 

usually have fire-fighting crews and equipment. Fuels Management Services firms provide 

services to clear land of hazardous materials that would fuel forest fires. The treatments used 

by these firms may include prescribed fire, mechanical removal, establishing fuel breaks, 

thinning, pruning, and piling.

18. NAICS code 541519 – An Information Technology Value Added Reseller (ITVAR) provides 

a total solution to information technology acquisitions by providing multi-vendor hardware and 

software along with significant value added services. Significant value added services consist 

of, but are not limited to, configuration consulting and design, systems integration, installation 

of multi-vendor computer equipment, customization of hardware or software, training, product 

technical support, maintenance, and end user support. For purposes of Government 

procurement, an information technology procurement classified under this exception and 150-

employee size standard must consist of at least 15% and not more than 50% of value added 

services, as measured by the total contract price. In addition, the offeror must comply with the 

manufacturing performance requirements, or comply with the non-manufacturer rule by 

supplying the products of small business concerns, unless SBA has issued a class or contract 

specific waiver of the non-manufacturer rule. If the contract consists of less than 15% of value 

added services, then it must be classified under a NAICS manufacturing industry. If the contract 
45

consists of more than 50% of value added services, then it must be classified under the NAICS 

industry that best describes the predominate service of the procurement.

19. NAICS Sector 92 – Small business size standards are not established for this sector. 

Establishments in the Public Administration sector are Federal, State, and local government 

agencies which administer and oversee government programs and activities that are not 

performed by private establishments. Concerns performing operational services for the 

administration of a government program are classified under the NAICS private sector industry 

based on the activities performed. Similarly, procurements for these types of services are 

classified under the NAICS private sector industry that best describes the activities to be 

performed. For example, if a government agency issues a procurement for law enforcement 

services, the requirement would be classified using one of the NAICS industry codes under 

NAICS industry 56161, Investigation, Guard, and Armored Car Services.
