Federal Classification
What Are NAICS Codes?
The North American Industry Classification System (NAICS) is the standard used by federal statistical agencies to classify business establishments for collecting, analyzing, and publishing statistical data related to the U.S. business economy.
For government contracting, NAICS codes help agencies identify qualified vendors and set small business size standards. They are essential for procurement officers searching for contractors with specific capabilities.
MH Chew Associates operates under multiple NAICS codes, reflecting our diverse expertise in scientific consulting, environmental services, and engineering.
