A Quick Guide to understanding the Hong Kong Standard Industrial Classification Code

5 minute read


The Hong Kong Standard Industrial Classification Code (HSIC) is a system that classifies economic units in Hong Kong. It divides each unit into relevant industry categories based on the nature of their major economic activities.

The Census and Statistics Department (C&SD) has implemented the Hong Kong Standard Industrial Classification Code Version 2.0 (HSIC V2.0) since 2009, relying on it for the compilation, analysis, and dissemination of industry statistics. It is widely used as a tool to compare statistical data surrounding national economic activity.

It is useful to know that the concept of HSIC is similar to Singapore’s SSIC, with slight variations. You would need a HSIC code to indicate your major business activities. Keep reading to learn more about HSIC, finding out why it’s important for Hong Kong businesses like yours, and the code that best represents your business activities.

What is a SIC code?

The first version of the Hong Kong Standard Industrial Classification Code (HSIC) was modeled on the ISIC Revision 2 that was introduced to the public in 1990. An updated version of HSIC V1.1 was introduced in 2001. Subsequently, the current version (HSIC V2.0) was released in 2008 and has been in use since 2009.

HSIC V2.0 was developed due to the significant changes in the structure of Hong Kong’s economy. There were too many new economic activities emerging and authorities needed to have a firmer grasp of the region’s economy.

HSIC V2.0 is based on the International Standard Industrial Classification (ISIC) of All Economic Activities Revision 4, which is promulgated by the United Nations Statistics Division. It aims to achieve better relevance, compatibility, and continuity. HSIC V2.0 changed in structure from a 4-level to a 5-level hierarchical system now has 21 top-level groups.

When it comes to changes designed to improve international comparability, HSIC V2.0 has a high degree of conformance with ISIC Rev. 4 (up to level 4).
To meet local requirements, HSIC went from 886 to 1,000 6-digit codes at its most detailed level.

As one might notice, it is similar to the codes of other countries, but is better crafted to suit the specific economy of Hong Kong.

How is it being used?

Logically, both privately-owned companies and government entities have these codes for a number of reasons:

  • Businesses use HSIC codes to identify their existing customers and potential customers by industry.
  • HSIC codes can be used to categorize companies for tax purposes.
  • HSIC codes are used by experts and businesses to create targeted marketing campaigns.
  • Businesses can identify the competition in their industry or region by searching for similar companies through HSIC codes.
  • The government can use HSIC codes to organize and standardize data for various public agencies (e.g. Census and Statistics Department) as well as private companies.

How can I choose a SIC Code for my business in Hong Kong?

It is important to choose a HSIC code that is best suited for the principal activities of your business. You should select a code that best reflects the activities for which you want to acquire a license from the state. To get a better idea, take a look at the list of industry codes (available in both Chinese and English).

For example, if you have a business that produces spices, sauces, and food condiments, it would only make sense to opt for a SIC code 107904.
To check on a specific SIC code in Hong Kong, simply use a code search tool. When you select the code, you will be able to apply for the necessary license that will allow you to operate  the borders of Hong Kong.

There are also detailed explanatory notes for the industries covered in the HSIC that you may want to check for more information.

  2. Under each industry section, there are different second-level categories called industry divisions.
  3. Further on, industry groups are under industry divisions.
  4. The fourth level refers to relevant industry classes.
