According to a survey by Vietnam Report, 80.8% of construction enterprises reported an increase in project volume in 2024 compared to 2023 (up from 47.4% in the previous survey). Additionally, 84.6% of companies reported a rise in their signed contract value (backlog), laying a foundation for growth in 2025.
Recognizing the booming construction sector in Vietnam—with strong development potential and rising infrastructure demand—many FDI enterprises are entering this field. However, not all investors are aware of the appropriate industry codes for business registration. Don’t worry—this article will help you identify the correct construction codes and guide you on how to combine multiple codes if needed.
What’s included in the latest 2025 construction industry code list?
Vietnam’s economic activity classification system is divided into 5 levels, with 4-digit level codes being the most commonly used for business registration. In the construction sector, these codes fall under Group F – Construction. Below is a list of updated level-4 construction industry codes based on Appendix I of Decision 27/2018/QĐ-TTg:
- 4101 – Construction of residential buildings: Includes individual houses, apartment buildings, and villas.
- 4102 – Construction of non-residential buildings: Offices, factories, shopping centers, and other commercial or industrial buildings.
- 4211 – Construction of railway projects: Rail tracks, railway bridges, and related structures.
- 4212 – Construction of roads: Highways, national roads, overpasses, tunnels, and other road infrastructure.
- 4221 – Construction of power projects: Power plants, substations, and transmission systems.
- 4222 – Water supply and drainage projects: Water systems, wastewater treatment, and irrigation structures.
- 4223 – Telecommunications infrastructure: Projects like BTS stations and fiber optic systems.
- 4229 – Other public utility projects: Parks, parking lots, and other public infrastructure.
- 4291 – Hydraulic construction: Ports, dams, canals, and other water-related structures.
- 4292 – Mining projects: Wells, tunnels, and other mining-related construction.
- 4293 – Industrial processing/manufacturing projects: Factories and storage for the manufacturing sector.
- 4311 – Demolition: Demolishing structures to prepare for new construction.
- 4312 – Site preparation: Land leveling, excavation, dredging, and other pre-construction activities.
- 4321 – Electrical installation: Installing electrical systems, lighting, and equipment.
- 4322 – Plumbing, heating, and air-conditioning: Installing water supply, cooling, and air-conditioning systems.
- 4329 – Other construction installations: Elevators, fire safety systems, and other technical installations.
- 4330 – Finishing works: Painting, plastering, tiling, glazing, and interior decoration.
- 4390 – Other specialized construction activities: Foundation reinforcement, waterproofing, and other specialized works.
Note: If your FDI company operates across multiple sectors (e.g., residential construction and electrical installation), you can register multiple industry codes to cover all business activities.
How to combine multiple construction industry codes for multi-sector businesses
Expanding into areas like residential construction, roadworks, and electrical installation requires combining industry codes to legally cover a wide range of activities. But how can you ensure legal compliance? Here’s a detailed guide from KMC:
Step 1: Identify your business activities
List all the current and intended business activities. Each activity corresponds to a specific code. For example, three different activities require three corresponding codes.
Step 2: Check conditions for combining multiple codes
You can register multiple construction industry codes, but there are legal conditions to meet:
Professional practice certificates
For activities like design or construction supervision (e.g., code 7110), your company must have 1–3 suitable professional practice certificates, depending on the project type. If these professionals are not company members, you must provide labor contracts and official appointment decisions.
Equipment and experience
For large-scale projects (e.g., Level I or II under code 4210), you must demonstrate experience with at least one Level I or two Level II projects. You also need to show the ability to mobilize necessary machinery and equipment (e.g., excavators, rollers).
Capital requirements
Some codes, like general civil construction (code 4100), may not require minimum capital or professional qualifications. However, if you intend to bid on major projects, you must comply with the capital regulations under the Law on Bidding (e.g., statutory capital or escrow deposits).
Step 3: Procedures for registering multiple industry codes
Prepare your documents:
- Notice of business registration information change (Appendix II-1, Circular 02/2019/TT-BKHĐT)
- Meeting minutes of the Board of Members/Shareholders or Owner’s Decision (depending on company type)
- Power of attorney (if the applicant is not the legal representative)
- Notarized copy of the applicant’s ID/passport
- For FDI enterprises: valid copies of the Investment Registration Certificate and Tax Registration Certificate
Submit your application
Submit your documents online to the Department of Planning and Investment using a digital signature or a registered business account. Within 3 working days, the Department will review and issue a certificate confirming the business registration update.
Public disclosure
Within 30 days of receiving the updated registration certificate, you must disclose the information on the National Business Registration Portal. Required documents include the disclosure request form, power of attorney, and ID copies of the applicant.
Choosing the right construction codes is crucial to ensure your business operations are legal and effective. Start by clearly defining your business activities and carefully checking legal requirements. If you need expert advice, don’t hesitate to contact KMC via hotline:
