Question # 9

9. What is the definition of primary SIC code? How can there be more than one SIC code for a facility?
A primary SIC code generally represents those goods produced or services performed by an establishment that have the highest value added. Form R and the Alternate Certification Statement (Form A) provide space for more than one SIC code because a facility may be made up of several establishments each of which may have a different primary SIC code. Note that the North American Industry Classification System (NAICS) is the economic classification system that replaced the 1987 SIC code system. A Federal Register notice was published on June 6, 2006 (71 FR 32464) adopting NAICS codes for TRI reporting.
