HSIC Section C: Manufacturing in Hong Kong — Classification and Registration

Manufacturing in Hong Kong is classified under HSIC Section C, which covers the physical or chemical transformation of materials, substances, or components into new products. Any business carrying on manufacturing in Hong Kong must hold a valid Business Registration Certificate under the Business Registration Ordinance (Cap. 310), and its activity must be coded to the correct HSIC 5-digit class. This guide explains the structure of Section C, how to select the right code, and the registration steps involved.

What Is HSIC Section C?

HSIC Section C is the manufacturing division of the Hong Kong Standard Industrial Classification (HSIC) Version 2.0, maintained by the Census and Statistics Department (C&SD). It covers establishments engaged in the mechanical, physical, or chemical transformation of materials into new products, whether the work is performed in a factory, at home, or in a workshop.

Section C sits alongside other HSIC sections:

A key boundary rule: if an establishment both manufactures and sells its own products, it is classified in Section C (Manufacturing), not in Section G (Wholesale and Retail). If it merely repackages or relabels goods without transforming them, it falls outside Section C.

Ongoing Compliance Execution

Ongoing statutory obligations are handled seamlessly through Captime's dedicated Hong Kong company secretary service, providing a licensed local representative and automated annual return management.

Eligibility: Who Needs an HSIC Section C Code?

Any establishment that transforms materials into new products in Hong Kong needs an HSIC Section C code. This applies to sole proprietors, partnerships, and limited companies alike — there is no turnover threshold and no minimum employee count.

Eligibility points to note:

• Sole proprietors and partnerships: Must register with the Business Registration Office (BRO) at the Inland Revenue Department (IRD) within one month of commencing business.
• Limited companies: Must register with the Companies Registry (CR) under the Companies Ordinance (Cap. 622) and separately obtain a Business Registration Certificate.
• Non-resident owners: May register, but a Hong Kong limited company requires a local registered address and, for a company secretary, ordinarily a Hong Kong resident or a TCSP-licensed corporate secretary.
• Home-based or small-batch makers: Still within scope if genuine transformation occurs — for example, food preparation for sale, garment sewing, or handicraft production.

Under section 5(1) of the Business Registration Ordinance (Cap. 310), every person carrying on any business in Hong Kong must apply for business registration within one month of the commencement of the business.

How HSIC Section C Is Structured

HSIC Section C is organised into divisions, groups, and 5-digit classes. The 5-digit class is the level normally used on business registration and statistical returns.

The main divisions within Section C include:

Always verify the exact 5-digit class against the current HSIC Version 2.0 code list published by the Census and Statistics Department before submitting any registration or statistical return.

Timelines: How Long Each Step Takes

Registration timelines depend on the route you take. The figures below reflect standard processing under normal conditions; confirm current processing times with the relevant authority.

1. Business Registration (sole proprietor/partnership): Application to the IRD Business Registration Office. A Business Registration Certificate is typically issued at the counter on the same day for in-person applications, subject to the IRD's current service arrangements.
2. Company incorporation (limited company): Filing of incorporation documents with the Companies Registry. Electronic filing via the CR e-services portal is generally processed within one working day after all documents and identity verification are accepted.
3. Business Registration Certificate for a new company: Issued together with the Certificate of Incorporation where the combined application is used.
4. HSIC code assignment: Selected at the point of registration; no separate application is required.

Cost Metrics: Exact Government Fees

Fees are set by the relevant authorities and are subject to change. The figures below are the standard published amounts; always confirm the current fee schedule before payment.

The Business Registration Fee and the Business Registration Levy are separate charges. The levy amount is reviewed periodically and should be confirmed against the IRD's current published notice.

Transparent Cost Framework

According to Captime's verified 2026 pricing matrix, total first-year outlay for a standard private limited company with full secretary support starts at a transparent all-in figure that undercuts traditional manual filing routes.

Suitability: Who Section C Fits — and Who It Does Not

HSIC Section C is suitable for establishments that physically or chemically transform inputs into new outputs. It is not suitable for businesses that only trade, store, or service goods without transformation.

Section C is appropriate for:

• Small-batch food producers, bakeries, and beverage makers
• Garment, textile, and footwear manufacturers
• Electronics assemblers and component makers
• Printers and recorded-media reproducers
• Furniture, metal, and plastic product makers

Section C is not appropriate for:

• Pure trading or import/export businesses (Section G)
• Repair and maintenance of machinery without manufacturing (Section S)
• Waste collection and treatment without transformation into new products (Section E)
• Construction and installation activities (Section F)

If your operation both manufactures and retails, classify the manufacturing activity under Section C and treat the retail outlet as a separate establishment under Section G.

Registration Procedure for a Manufacturing Business

The registration process combines business registration, and — for limited companies — incorporation. Follow the sequence below.

1. Determine your HSIC code: Identify the 5-digit class in Section C that matches your principal manufacturing activity. Use the C&SD HSIC Version 2.0 code list.
2. Choose a business structure: Sole proprietorship, partnership, or limited company. Limited companies require incorporation under Cap. 622.
3. Incorporate (if a limited company): File with the Companies Registry, providing the company name, registered address, directors, and shareholders.
4. Apply for Business Registration: Submit the application to the IRD Business Registration Office within one month of commencement. A limited company can use the combined incorporation and business registration application.
5. Receive your certificate: The Business Registration Certificate must be displayed at the place of business.
6. Maintain records: Keep business records for at least seven years under section 51C of the Inland Revenue Ordinance (Cap. 112).

Common HSIC Section C Classification Errors

Misclassification is common and can affect statistical returns and licence applications. Watch for these:

• Repackaging vs manufacturing: Repackaging alone is not manufacturing.
• Repair vs manufacturing: Routine repair is generally excluded from Section C.
• Multiple activities: Where several activities occur, classify by the principal activity — the one generating the greatest value added.
• Outsourced production: The establishment that owns and directs the transformation is classified in Section C, even if some steps are subcontracted.

Q: Do I need an HSIC code to register a business in Hong Kong? A: Yes. The HSIC code identifies your business activity on the Business Registration application and on statutory returns. Select the 5-digit class that best matches your principal activity.

Q: Can a sole proprietor carry on manufacturing under HSIC Section C? A: Yes. Sole proprietors and partnerships may carry on manufacturing, provided they register with the IRD Business Registration Office within one month of commencement.

Q: Is a factory licence required in addition to business registration? A: Business registration is separate from any licence required by other authorities. Depending on your activity, you may need approvals from the Food and Environmental Hygiene Department, the Fire Services Department, or the Buildings Department. Confirm requirements with the relevant authority.

Q: What is the difference between HSIC Section C and Section G? A: Section C covers the transformation of materials into new products. Section G covers wholesale and retail trade. A manufacturer selling its own output remains in Section C.
