Overview

The North American Industry Classification System (NAICS) is the framework used by U.S. statistical agencies to classify business establishments for producing economic data. NAICS was adopted in 1997 under the Office of Management and Budget (OMB) and was developed jointly by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s national statistics agency to ensure comparability across North America. ¹

Official examples include prescription eyeglasses (other than those made in a retail setting), contact lenses, sunglasses, eyeglass frames, and reading glasses made to standard powers.
