29 CFR 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.”
(b) The Standard Industrial Classification (SIC) codes listed in appendix A and B herein are designated in accordance with the Standard Industrial Classification (SIC) Manual, 1987, published by the Executive Office of the President, Office of Management and Budget. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 1 CFR part 51.
