Vietstock applied NAICS 2007 (The North American Industry Classification System) for industry classification because of its popularity, comprehension and logical order. In addition, it receives many supports from international organizations and bears a lot of similarities to Vietnam Standard Industrial Classification (VSIC 2007).
When classifying industries, Vietstock takes revenue structure as the first priority. Accordingly, the main business scope of a company is the one which contributes over 50% of the total revenue.
