The Small Business Administration (SBA) is amending its size regulations by establishing a new table of small business size standards for industries as the North American Industry Classification System (NAICS) defines them. These new size standards are effective beginning with Fiscal Year 2001, which starts on October 1, 2000. Small business size standards currently exist for most industries under the Standard Industrial Classification (SIC) system. SBA has determined that NAICS is a better description of industries in the U.S. economy than the SIC system for purposes of establishing size standards.
