§ 510.21 SIC codes.

(a) The Conference Report specifically cites Puerto Rico's annual Census of Manufacturing Industries as a source of average hourly wage data by industry. Industries in that census are organized by Standard Industrial Classification (SIC), the statistical classification system used for a variety of governmental and statistical purposes. With respect to non-manufacturing industries, or other industries not included in the Census of Manufacturing, the Conference Report stated that data “should be at a level of specificity comparable to the four digit Standard Industry Code (SIC) code level.”
