Overview of NAICS (North American Industry Classification System)
The North American Industry Classification System (NAICS) is an industry classification system developed jointly by the United States, Canada, and Mexico. Introduced in 1997, NAICS serves as a standard industry classification method that more accurately reflects the economic activities and industry structures of each country, replacing the SIC (Standard Industrial Classification) system. NAICS classifies each industry with a six-digit code and plays a crucial role in the collection of economic statistics, industry analysis, market research, and business strategy development.
The implementation of NAICS reflects the integration of trade and business within the North American region, providing a foundation that facilitates business activities, particularly for international companies and global trade relations. This system is jointly managed by the three countries and is reviewed every five years, allowing it to incorporate up-to-date information that meets the needs of changing industries and emerging markets.
The Use of NAICS and Its Impact on International Business
Beyond the United States, Canada, and Mexico, NAICS is also referenced by international companies and economic analysis institutions for industry comparison and statistical standardization across countries. For example, companies and market research firms that use corporate databases can leverage NAICS codes to identify target markets and conduct positioning analysis. Additionally, NAICS codes are utilized to understand market size, growth trends, and competitive environments within specific industries, aiding in the development of international business strategies.
