The United States Small Business Administration (SBA) is increasing the small business size standards for 22 industries in North American Industry Classification System (NAICS) Sector 48-49, Transportation and Warehousing, and retaining the current standards for the remaining 37 industries in that Sector. As part of its ongoing comprehensive review of all size standards, SBA has evaluated all receipts based standards for industries in NAICS Sector 48-49 to determine whether they should be retained or revised. SBA did not review the employee based standards for industries in NAICS Sector 48- 49, but will do so at a later date with other employee based size standards.
