The U.S. Small Business Administration (SBA) is adopting, without change, its proposed revisions to small business size standards. With the adoption of the proposed changes, SBA incorporates the U.S. Office of Management and Budget's (OMB) North American Industry Classification System (NAICS) revision for 2017, identified as NAICS 2017, into its table of small business size standards. NAICS 2017 created 21 new industries by reclassifying, combining, or splitting 29 existing industries under changes made to NAICS in 2012 (NAICS 2012). SBA's size standards for these 21 new industries have resulted in an increase to size standards for six NAICS 2012 industries and part of one industry, a decrease to size standards for two, a change in the size standards measure from average annual receipts to number of employees for one, and no change in size standards for twenty industries and part of one industry.
