The steel industry is segmented into Standard Industrial Classifications (SICs) based on the type of processing route used and the final products generated. In 1997, the Office of Management and Budget (OMB) reclassified all U.S. industries under new codes - the North American Industry Classification System, or NAICS [OMB 1997]. These new classifications will be used in the next Census of Manufactures conducted by the Department of Commerce, as well as by other Federal agencies that collect data from industry. However, most industry data are currently only available according to SIC codes.
