A Guide to Hong Kong Standard Industrial Classification Code

As Hong Kong’s economy expanded, new industries emerged, requiring a more precise classification system. HSIC V2.0 was designed to:

• Improve accuracy and relevance in business classification.
• Align with global industry classification standards while adapting to Hong Kong’s unique economic structure.
• Expand from a four-level to a five-level hierarchical system, increasing classification detail.
• Increase the number of industry categories from 886 to over 1,000 six-digit codes.

Why Does the HSIC Code Matter for Your Business?

The HSIC Code isn’t just a registration requirement—it affects regulations, government policies, and business strategy. Choosing the right code ensures compliance, accurate industry data, and better decision-making. Here’s why it matters:

1. Required for Company Registration

When registering a company in Hong Kong, you must select an HSIC Code that reflects your business activities. This ensures the government keeps accurate records and categorizes businesses correctly. The Census and Statistics Department (C&SD) uses this information for economic reporting and industry analysis.

2. Impacts on Government Policies and Industry Regulations

HSIC codes help the government track industry performance and shape policies that affect businesses. Certain sectors may receive tax incentives, funding opportunities, or regulatory benefits based on their classification. Using the correct HSIC code ensures your business is classified appropriately for any industry-specific policies.

3. Essential for Market Research and Business Strategy

Businesses can use HSIC codes to analyze industry trends, assess competition, and make informed strategic decisions. Understanding how companies in your sector are classified helps with benchmarking and identifying market opportunities. If you're considering Hong Kong offshore company formation, proper classification can also impact regulatory requirements and tax benefits.

4. Used for Economic and Statistical Reporting

Government agencies, investors, and analysts rely on HSIC codes to study market trends, employment rates, and sector growth. Choosing the right code ensures your business data is accurately reflected in economic reports, which can influence industry forecasts and investment trends.

Understanding the Structure of HSIC Codes

The HSIC Code follows a five-level structure, grouping businesses from broad industry categories down to specific activities. This system ensures businesses are classified accurately for registration, reporting, and policy-making.

Here’s how the structure works:

1. Industry Section (Top Level) – 1 Letter Code (A-U)

At the highest level, businesses are grouped into 21 major industry sections, each represented by a single letter (A to U). This gives a general idea of what sector a business belongs to.

Example:

• **G: **Import/export, wholesale, and retail trades
• J: Information and communications

2. Industry Division – 2-Digit Code (01-99)

Each Industry Section is broken down into 88 Industry Divisions, using a two-digit numeric code. This level provides a bit more detail about the business type.

Example:

• 47: Retail trade (under Section G)
• **62: **Computer programming, consultancy, and related activities (under Section J)

3. Industry Group – 3-Digit Code (011-990)

Industry Divisions are further divided into 221 Industry Groups, represented by a three-digit code. This level focuses on the nature of the business in more depth.

Example:

• 472**: **Retail sale of food, beverages, and tobacco in specialized stores (under Retail Trade - 47)
• 620: Computer programming and software development (under Computer Services - 62)

4. Industry Class – 4-Digit Code (0110-9900)

The 483 Industry Classes provide an even more specific classification by defining the main business activity.

Example:

• 4721: Retail sale of food in specialized stores (under Retail Food Sales - 472)
• **6201: **Software development (under Computer Programming - 620)

5. Industry Sub-class (Most Detailed) – 6-Digit Code (011000-990000)

At the most detailed level, 1,001 Industry Sub-classes define the exact nature of a business using a six-digit code.

Example:

• **472105: **Retail sale of fresh fruits and vegetables (under Retail Sale of Food - 4721)
• **620101: **Development of mobile applications (under Software Development - 6201)

This five-level system makes it easier to classify businesses accurately, ensuring clarity in registration, compliance, and economic reporting. Each level refines the classification, so businesses fall into the right category without overlap.
