SIC

According to the FAQs on the CCR website:

SIC Codes Standard Industrial Classification Code Codes that classify the type of business an organization offers. Used for an EPA certification. Occupational Safety & Health Administration(OSHA)

According to the NAICS website (http://www.census.gov/eos/www/naics/faqs/faqs.html#q8):

8. What is the Standard Industrial Classification (SIC) system? Is it still being used?

NAICS replaced the SIC in 1997. Now the Federal statistical agencies use NAICS for the collection, tabulation, presentation, and analysis of economic statistics. There will be no further revisions of the SIC, which was last updated in 1987. It is possible that other organizations and state and local agencies are continuing to use the SIC for their own purposes, but these non-statistical uses are outside the scope of the Federal economic statistical programs.

To find the SIC codes and their descriptions, visit the Occupational Safety & Health Administration (OSHA) website, which maintains a SIC Manual.

To learn more about the differences between the original 1997 NAICS and the SIC, visit the "History" link on this website.

A detailed conversion (concordance) between the SIC and 2002 NAICS is available in Excel format for download at the "Concordances" link on this website. There are no plans to develop a concordance between the SIC and 2007 NAICS.
