Vietnam Manufacturing Industry Codes 2025: VSIC Comparison Under Decision 36/2025

Vietnam’s manufacturing sector remains the backbone of industrial growth, export expansion, and supply-chain repositioning in Southeast Asia. Yet behind factory openings and capital inflows, one of the most decisive “make-or-break” details for investors is often administrative: the correct classification of manufacturing activities under Vietnam’s industry code system. After the Prime Minister issued Decision No. 36/2025/QĐ-TTg (Decision 36), the country’s industrial classification framework was modernized under Vietnam Standard Industrial Classification (VSIC 2025), replacing the older structure and taking effect on November 15, 2025.

For both foreign direct investment (FDI) and domestic direct investment (DDI), the shift is not cosmetic. Manufacturing industry codes directly shape enterprise registration scope, investment licensing interpretation, compliance reviews, and incentive eligibility. In a sector where companies frequently operate across multiple production stages—components, assembly, testing, and packaging—accuracy in code selection is now central to smooth approvals and long-term regulatory clarity.

1. Why Manufacturing Industry Codes Matter for Investors in Vietnam

Industry classification codes are foundational to how economic activities are defined and processed across business registration, licensing, and government reporting. In Vietnam’s manufacturing context, these codes commonly influence the content and defensibility of enterprise registration dossiers, how investment projects are categorized for review, and how the company’s operating scope is interpreted during inspections. They also matter because manufacturing spans many sub-sectors—from electronics and machinery to textiles, chemicals, and food processing—where sub-classification can determine whether your registration reflects your real production line or remains vague enough to trigger follow-up questions.

International investors also care because standardized classification improves comparability across markets. When Vietnam’s system is more structured and aligned in practice, multinational groups can map Vietnam operations to internal reporting categories more consistently, reducing friction for governance, compliance tracking, and multi-country portfolio analysis.

2. Manufacturing Classification Before 2025 Under the Old VSIC System

Before VSIC 2025, manufacturing codes under the prior structure were workable but often broader than modern manufacturing realities. Many manufacturing businesses fell under large groupings that could blur distinctions between sub-activities, particularly for companies that operated across several niches or production stages. This sometimes created overlap when enterprises needed to describe high-tech production, specialized component manufacturing, or hybrid operations that mix manufacturing with supporting services.

As a result, manufacturers frequently had to add supplementary business lines to represent their full operational scope. While that approach could cover practical needs, it also increased complexity during filings and raised the risk that the registered scope did not fully match the company’s actual production and service activities.

3. Manufacturing Classification After November 15, 2025 Under VSIC 2025 and Decision 36/2025

Under Decision 36/2025, VSIC 2025 moves toward stronger granularity and clearer differentiation across manufacturing segments. The updated framework supports more precise classification for core sub-sectors such as electronics, textiles, chemicals, machinery, and food and beverage processing, while also allowing a cleaner distinction between manufacturing itself and related supporting activities. This matters in practice because factories increasingly rely on specialized services such as testing, precision fabrication, or technical processes that may not be adequately described under broad umbrella codes.

For investors, the key improvement is reduced ambiguity. A clearer mapping between what a factory actually does and what its registration states helps minimize registration friction, improves compliance defensibility, and supports more accurate incentive assessment.

4. Side-by-Side Manufacturing Code Comparison Examples

Manufacturing investors frequently ask for a simplified way to understand the shift, especially because the updated VSIC structure extends into deeper levels of detail. In practical terms, textile manufacturing can move from broad groupings to clearer segmentation by production stages such as spinning, weaving, and dyeing. Electronics assembly can shift from generic “electrical goods” classifications toward more explicit electronics and component assembly categories. Food processing can become more segmented to distinguish beverages, packaged foods, and other sub-types that better match industrial reality.

Because the exact code numbers depend on the final sub-classification level and the precise activity description, investors typically treat these as structural changes rather than one-size-fits-all replacements. The best approach is to map the factory’s processes and products to the closest VSIC 2025 structure rather than forcing a legacy label onto a new system.

5. What VSIC 2025 Means for FDI and DDI: Registration, Compliance, and Incentives

For investment projects, accurate enterprise and investment registration is the first high-stakes impact. When investors select a manufacturing industry code that is too broad, too narrow, or mismatched to the real production line, the result can include longer processing cycles, clarification requests, or later compliance flags. Conversely, an accurate selection helps ensure that registration documents reflect intended operations, which is essential for factories that plan to expand from assembly into component production, or from core manufacturing into testing and supporting functions.

Incentive eligibility is another major consequence. Vietnam’s investment incentive frameworks often connect preferential treatment to specific categories of activities, and manufacturing projects—especially in high-tech or export-oriented areas—may be sensitive to how the activity is formally classified. The correct VSIC 2025 mapping helps investors assess incentives more reliably and avoid situations where a project is operationally eligible but administratively unclear.

6. Tools That Make Manufacturing Code Comparison Faster and More Defensible

The practical challenge after any classification reform is execution. Investors need to translate a business model into a registration-ready set of codes, often under time pressure, and frequently across multiple entities such as a holding company, a project company, and an operations company. This is where tools that accelerate mapping and reduce ambiguity become valuable for both legal and investment teams.

ChatIIP — AI-Powered Industry Comparison is designed for exactly this kind of old-to-new mapping problem. Many investors use ChatIIP to quickly compare old vs. new industry codes, assess the best matches for your manufacturing business model, and generate tailored registration guidance that can be reused across dossiers and internal documentation. Whether you’re setting up a manufacturing holding company, an FDI project entity, or a regional office that manages multiple factory sites, ChatIIP can help interpret regulatory language and map activities to the most accurate VSIC codes, saving time and reducing risk when classification details become the bottleneck.

IIPMap — Visual Investment Insights complements classification work by supporting the location and market side of the decision. In practice, manufacturers are not only choosing codes; they are also choosing industrial zones, infrastructure corridors, and cluster ecosystems that determine logistics performance and labor access. This is why investors use IIPMap, as it offers geographic and investment insight tools that help real estate and manufacturing investors understand market dynamics and investment hotspots across Vietnam. Used together with industry code classification, IIPMap provides both strategic data and market context for on-the-ground decisions, especially when projects depend on proximity to ports, supplier ecosystems, or specialized industrial clusters.

7. Local Market Context and Industrial Updates

Beyond code classification and mapping, investors often need local visibility into industrial activity trends, policy interpretation, and project pipelines. Platforms such as IIP Vietnam can provide ongoing context that helps manufacturers understand segment movements and industrial corridor dynamics, particularly for electronics supply chains, supporting industries, and export-oriented manufacturing.

8. Practical Implementation Steps for Manufacturing Investors

A practical approach starts by listing the full set of production activities you will perform, including processes that might be treated as supporting services or separate sub-activities under a more granular system. From there, investors can map those activities to the best-fit VSIC 2025 structure, identify which code should be primary versus supplementary, and confirm alignment with the project’s licensing and incentive strategy. Many teams then use tools such as ChatIIP to accelerate the comparison and reduce ambiguity, and leverage IIPMap to validate site strategy alongside the administrative setup.

Vietnam’s move to VSIC 2025 under Decision 36/2025 marks a significant shift toward clearer and more internationally comparable industrial classification. For manufacturing investors, the change increases precision and reduces ambiguity, but it also raises expectations for accurate registration scope. Investors who treat industry codes as a strategic foundation—rather than a checkbox—will be better positioned to secure smoother approvals, reduce compliance risk, and build scalable manufacturing operations.

To operationalize that strategy, many investors now rely on ChatIIP for AI-assisted industry comparison and code mapping, while using IIPMap to connect classification with geographic investment insights and industrial hotspot analysis.
