Singapore Standard Industrial Classification (SSIC)

The Singapore Standard Industrial Classification (SSIC) is the national standard for classifying economic activities undertaken by economic units and is used in censuses of population, household and establishment surveys and in administrative databases. The SSIC adopts the basic framework and principles of the International Standard Industrial Classification of All Economic Activities (ISIC). It is reviewed and updated regularly to reflect significant changes in the structure of the Singapore economy and the emergence of new activities, as well as to align with changes in international standards.
The Accounting and Corporate Regulatory Authority (ACRA) require entities (business or company) to declare their business activities during incorporation. Each entity will have to report at least one business activity (Principal Activity) but no more than two (Secondary Activity). Businesses or companies can change their declared business activities any time after incorporation through BizFile. This information allows the government to know what industry is present in the country to help make policies.
The SSIC comes with two key components, the SSIC code and industry or activity description and follows a hierarchical principle of classification by Section, Division, Group, Class and Sub-class.
The code is based on the latest SSIC Version issued by the Department of Statistics. (Singapore Standard Industrial Classification SSIC 2020)
